abstract = {We report from a study exploring the boundaries of the peripheral perception of vibro-tactile stimuli. For three days, we exposed 15 subjects to a continual vibration pattern that was created by a mobile device worn in their trouser pocket. In order to guarantee that the stimuli would not require the subjects' focal attention, the vibration pattern was tested and refined to minimise its obtrusiveness, and during the study, the participants adjusted its intensity to just above their personal detection threshold. At random times, the vibration stopped and participants had to acknowledge these events as soon as they noticed them. Only 6.5% of the events were acknowledged fast enough to assume that the cue had been on the focus of the participants' attention. The majority of events were answered between 1 and 10 minutes, which indicates that the participants were aware of the cue without focussing on it. In addition, participants reported not to be annoyed by the signal in 94.4% of the events. These results provide evidence that vibration patterns can form non-annoying, lightweight information displays, which can be consumed at the periphery of a user's attention.},

abstract = {Virtual navigation on a mobile touchscreen is usually performed using finger gestures: drag and flick to scroll or pan, pinch to zoom. While easy to learn and perform, these gestures cause significant occlusion of the display. They also require users to explicitly switch between navigation mode and edit mode to either change the viewport's position in the document, or manipulate the actual content displayed in that viewport, respectively. SidePress augments mobile devices with two continuous pressure sensors co-located on one of their sides. It provides users with generic bidirectional navigation capabilities at different levels of granularity, all seamlessly integrated to act as an alternative to traditional navigation techniques, including scrollbars, drag-and-flick, or pinch-to-zoom. We describe the hardware prototype, detail the associated interaction vocabulary for different applications, and report on two laboratory studies. The first shows that users can precisely and efficiently control SidePress; the second, that SidePress can be more efficient than drag-and-flick touch gestures when scrolling large documents.},

abstract = {A novel interaction style is presented, allowing in-pocket music selection by tapping a song's rhythm on a device's touchscreen or body. We introduce the use of rhythmic queries for music retrieval, employing a trained generative model to improve query recognition. We identify rhythm as a fundamental feature of music which can be reproduced easily by listeners, making it an effective and simple interaction technique for retrieving music. We observe that users vary in which instruments they entrain with and our work is the first to model such variability. An experiment was performed, showing that after training the generative model, retrieval performance improved two-fold. All rhythmic queries returned a highly ranked result with the trained generative model, compared with 47% using existing methods. We conclude that generative models of subjective user queries can yield significant performance gains for music retrieval and enable novel interaction techniques such as rhythmic filtering.},

abstract = {This paper introduces VibPress, a software technique that enables pressure input interaction on mobile devices by measuring the level of vibration absorption with the built-in accelerometer when the device is in contact with a damping surface (e.g., user's hands). This is achieved using a real-time estimation algorithm running on the device. Through a user evaluation, we provide evidence that this system is faster than previous software-based approaches, and accurate as hardware-augmented approaches (up to 99.7% accuracy). With this work, we also provide an insight about the maximum number of pressure levels that users can reliably distinguish, reporting usability metrics (time, errors and cognitive load) for different pressure levels and types of gripping gestures (press and squeeze).},

From our analysis we identify three guidelines for mobile annotation systems design in biological fieldwork that we argue also extend to other domains: allowing the management of space through user control over annotation processes, promoting structured but flexible annotation through user-defined annotation formats, and providing robust and comprehensive integration of disparate data sources to allow ad hoc, exploratory queries.},

abstract = {The paper reports on the growing phenomena of art-making on mobile devices and contributes findings from two studies of artists' responses to iPad painting apps: the first is a series of exploratory workshops where artists were recruited to engage with a range of art apps, the second is a series of in-depth interviews with two artists who had incorporated the device and Brushes app into their painting practice over a period of months and years. The artists in both studies generally agreed that the devices and apps were easy to use and enjoyable but remained ambivalent about the technologies and outcomes. Although there was excitement around new creative possibilities there were also tensions around the status of the work being produced. The paper reflects on the role of popular digital production apparatus and information exchange on the constitution of artist-identities at a time of rapid techno-cultural change. It argues that while tablet computing and art apps have democratized certain artistic processes these technologies have generated conflict with traditional conceptions of art and curation.},

Usually, a paper tag is attached to each patient containing their classification and the results of an initial, quick diagnosis. Several projects have aimed to electronically augment the process by using ubiquitous computing components. In this paper we present drawbacks of introducing technology to the process, which have not been discussed elsewhere, based on an extensive set of expert workshops discussing the employment of technology in triage with the aid of technology probes. Our main finding is that the common set of functionalities of electronic triage systems involves unwanted reconfiguration of triage processes. By presenting a set of implications for the design of these mobile technologies, we show how potential negative effects can be mitigated.},

If the app on the mobile screen requires user interaction when something exciting is about to happen on the TV screen, the user needs to shift attention from the TV to the mobile screen, spoiling the whole experience. This paper presents WeBet, a mobile game that prompts users to bet if a goal is about to happen during a football match, without requiring their visual attention. WeBet aims to study if this concept conveys an exciting user experience by allowing a natural interaction with the mobile screen without looking at it. Results from a preliminary user test helped to validate our approach and identified important refinements for future work.},

abstract = {We propose a technique called voice augmented manipulation (VAM) for augmenting user operations in a mobile environment. This technique augments user interactions on mobile devices, such as finger gestures and button pressing, with voice. For example, when a user makes a finger gesture on a mobile phone and voices a sound into it, the operation will continue until stops making the sound or makes another finger gesture. The VAM interface also provides a button-based interface, and the function connected to the button is augmented by voiced sounds. Two experiments verified the effectiveness of the VAM technique and showed that repeated finger gestures significantly decreased compared to current touch-input techniques, suggesting that VAM is useful in supporting user control in a mobile environment.},

In this paper, we investigate the single-handed thumb performance of eyes-free, absolute position control on mobile touch screens. Both 1D and 2D experiments were conducted. We explored the effects of target size and location on eyes-free touch patterns and accuracy. Our findings show that variance of touch points per target will converge as target size decreases. The centroid of touch points per target tends to be offset to the left of target center along horizontal direction, and shift toward screen center along vertical direction. Average accuracy drops from 99.6% of 2\texttimes{}2 layout to 85.0% of 4\texttimes{}4 layout, and average per target varies depending on the location of target. Our findings and design implications provide a foundation for future researches based on eyes-free, absolute position control using thumb on mobile devices.},

We focus on the disambiguation step needed when several objects are selected with a rough pointing gesture. A usual disambiguation technique forces the users to switch their focus from the physical world to a list displayed on a handheld device's screen. In this paper, we explore the balance between change of users' focus and performance. We present two novel interaction techniques allowing the users to maintain their focus in the physical world. Both use a cycling mechanism, respectively performed with a wrist rolling gesture for P2Roll or with a finger sliding gesture for P2Slide. A user experiment showed that keeping users' focus in the physical world outperforms techniques that require the users to switch their focus to a digital representation distant from the physical objects, when disambiguating up to 8 objects.},

The work at hand is concerned with the design of innovative user interfaces (UI) for viewing MVVs. As a first contribution four different MVV UIs are designed. While different in design, their common aim is to allow a pleasant viewing and perspective switching experience by reducing the cognitive effort associated with constructing a mental map of the scene. This is achieved by incorporating the spatial relationships of the available views in the UI elements. As a second contribution a quality model is developed and a methodical evaluation process is designed. This is used to evaluate and compare the UIs. In a third contribution we use principal component analysis (PCA) to reveal information about the perceptual quality space which helps validating our proposed quality model. Based on the findings, a series of conclusions for best design practices are provided.},

Lens-like approaches have significant potential because they can support navigation-selection, navigation-annotation, and other such compound tasks by off-loading navigation to the nonpreferred hand while the preferred hand annotates, marks a location, or draws a path on the screen. Our experimental results show that the Chameleon Lens is significantly slower than Pinch-Flick-Drag for the navigation subtask in isolation. But our studies also reveal that for navigation between a few known targets the lens performs significantly faster, that differences between the Chameleon Lens and Pinch-Flick-Drag rapidly diminish as users gain experience, and that in the context of a compound navigation-annotation task, the lens performs as well as Pinch-Flick-Drag despite its deficit for the navigation subtask itself.},

Since no physical device is involved, users can switch quickly and effortlessly among a number of devices.We demonstrate the potential of Imaginary Devices with Grand Theft Auto, a game that requires players to change between roles often and quickly, and we examine the viability of the concept in two user studies. In the first study, we found that participants produced a wide range of postures to represent each device but all were able to reproduce the correct posture after a short demonstration. In the second study, we found that Imaginary Devices afford precise input control and approach the baseline performance set by physical devices.},

Moreover, the lack of scientific evidence about the concrete impact of mobile phones' screen size on usability raises questions both to practitioners and researchers. In this paper, we investigate the impact of a mobile phone's screen size on users' effectiveness, efficiency and perceived usability as measured using System Usability Scale (SUS). An experiment was conducted with 60 participants, which interacted with the same information seeking application on three different devices of the same brand that differed on their screen size. A significant effect of screen size on efficiency was derived, leading to an important finding that users who interact with larger than 4.3in screens are more efficient during information seeking tasks.},

Even though driving itself has remained relatively unchanged, there are now a wide variety of new in-car tasks, which people perform with both integrated infotainment systems and their mobile devices. To gain insights into this new task context and how it could be improved, we conducted a qualitative, contextual study in which we observed real-life car journeys with eight participants. The focus was on user interaction with touchscreen mobile devices, due to their wide range of functions and services. The findings show that the car is an extension of other contexts and it contains a rich set of infotainment tasks, including use of social media. Drivers emphasized gesture interaction and the use of non-visual modalities, for replacing visual information and notifying of changes in the driving context. Based on the findings, we present design implications for future in-car infotainment systems.},

abstract = {Mobile devices are being used in more and more complex settings such as cars or medical environments and these environments are causing serious distractions for the mobile user. This paper presents novel research that investigates mobile user experiences when interacting with cognitively demanding distractions. This research finds that, surprisingly, the user's primary task is not always affected by the distraction but, in this case, the actual interaction between user and device is. This observation initially appears to contradict current research which suggests that a distraction will affect the primary task. The main conclusion of this paper is that a user, when dealing with distraction, can balance their cognitive processes by applying less cognitive resources to the mobile device interaction in order to maintain their performance at the primary task. Essentially, the interface can appear more difficult and less user friendly.},

abstract = {Pinching and spreading gestures are prevalent in mobile applications today, but these gestures have not yet been studied extensively. We conducted an exploratory study of pinch and spread gestures with seated participants on a phone and a tablet device. We found device orientation did not have a significant effect on gesture performance, most pinch and spread tasks were completed in a single action, and they were executed in 0.9-1.2 seconds. We also report how participants chose to sit with the mobile device, variations in gesture execution method, and the effect of varying target width and gesture size. Our task execution times for different gesture distances and precision levels display a surprisingly good fit to a simple Fitts's Law model. We conclude with recommendations for future studies.},

abstract = {We present a single-handed and eyes-free Japanese kana text input system on touch screens of mobile devices. We first conducted preliminary experiments to investigate the accuracy with which subjects could single-handedly point to and flick without using their eyes. We found from the results that users can point at a screen that was divided into 2 x 2 with 100% accuracy and that users can flick at a 2 x 2 grid without using their eyes with 96.1% accuracy using our algorithm for flick recognition. The system used kana letter input based on two-stroke input with three keys to enable accurate eyes-free typing. First, users flick for consonant input, and then similarly flick for vowel input. We conducted a long-term user study to measure basic text entry speed and error rate performance under eyes-free conditions, and readability of transcribed phrases. As a result, the mean text entry speed was 51.2 characters per minute (cpm) in the 10th session of the user study and the mean error rate was 0.6% of all characters. The mean text entry speed was 33.9 cpm in the 11th session, which was conducted under totally eyes-free conditions and the mean error rate was 4.8% of all characters. We not only measured cpm and error rate, but also measured error rate of reading, which we devised as a novel metric to measure how accurately users can read transcribed phrases. The mean error rate of reading in the 11th session was 5.7% of all phrases.},

abstract = {Drawing and handwriting play a central role in primary schools. So far handwriting is practiced mainly on paper and blackboards. Providing tasks on paper can be challenging in developing countries. With the potential availability of mobile phones in classrooms, there is a new medium that can be used. We determined the effect of different touch technologies on children's handwriting for 18 third grade and 20 sixth grade participants. Children drew and wrote using different input techniques. We measured their performance and asked teachers to assess the legibility. We show that writing on touchscreens is less legible and slower than on paper. Further, the comparison of touchscreen technologies indicates that capacitive screens operated with a stylus yield the highest readability and are faster to use for writing than resistive screens. In contrast to these quantitative findings participants from third grade indicated that they prefer resistive screens with a thin stylus compared to using capacitive screens with a stylus or fingers.},

abstract = {This Note introduces a keyboard design that affords ten-finger touch typing by utilizing a touch sensor on the back side of a device. Previous work has used physical buttons. Using a touch sensor has the benefit that it retains the form factor and does not insist on a peripheral device. Moreover, any layout can be used. However, it is difficult to hit targets on a flat surface with no haptic feedback. Sandwich Keyboard is a prototype that folds any three-row keyboard layout and thus, by retaining the finger-to-letter assignment, supports transfer. Sandwich Keyboard includes an algorithm for constant adaptation of key targets in the back. We also learned that the detection of key presses from finger release enhances the performance of touch-typing on a multitouch sensor. After eight hours of training, experienced typists of the QWERTY and of the Dvorak Standard Keyboard (DSK) layout reached 26.1 and 46.2 wpm, respectively. We discuss improvements necessary for further increasing both speed and accuracy.},

The auto-segmentation algorithm was designed for practicality; it is extremely simple, requires only public domain data for training, and runs very fast on low-power devices. Drawings may also be included with the text. Experimental data indicates the effectiveness of our system, even for novice users.},

Results indicate that location-sharing decisions depend on the perceived visibility of the check-in, blur boundaries between public and private venues, and can initiate tensions within the foursquare friend network. We introduce the concept of "check-in transience" to explain factors contributing to impression management and argue that sharing location is often used as a signaling strategy to achieve social objectives.},

The user can benefit from enriching the 2D-map-based navigation with panoramic imagery from the citizen's perspective, hence gaining an authentic view of the frequent landmarks that urban environments include. In this paper we describe the user-centered design of a mobile street-imagery-based navigation service supporting navigation and exploration of unfamiliar cities. The service was evaluated with a field trial using tourists as participants. The participants used the service freely for the pedestrian navigation tasks that were relevant to them during the trial period. This approach shed light on issues that have not been raised by previous studies on image-based navigation, which have relied on more formal test tasks. The study confirmed that the images help with detecting the destination or assessing the atmosphere of a remote location but brought into focus the real world challenges related to downloading times and positioning accuracy.},

Our system primarily uses automatically detected business signs as landmarks, and currently works in a half dozen cities around the world. We have also evaluated our system and found that people can effectively navigate solely using landmark enhanced panoramas of decision points along the route.},

abstract = {We present a study that investigates the potential of combining, within the same interaction cycle, deformation and touch input in a handheld device. Using a flexible, input-only device connected to an external display, we compared a multitouch input technique and two hybrid deformation-plus-touch input techniques (bending and twisting the device, plus either front- or back-touch), in an image-docking task. We compared and analyzed the performance (completion time) and user experience (UX) obtained in each case, using multiple assessment metrics. We found that combining device deformation with front-touch produced the best UX. All the interaction techniques showed the same efficiency in task completion. This was a surprising finding, since multitouch (an integral input technique) was expected to be the most efficient technique in an image docking task (an interaction in an integral perceptual space). We discuss these findings in relation to self-reported qualitative data and observed interaction-procedure metrics. We found that the interaction procedures with the hybrid techniques were more sequential but also more paced. These findings suggest that the benefits of deformation input can still be observed when deformation and touch are combined in an input device.},

We designed a new graphical password scheme called Touchscreen Multi-layered Drawing (TMD) specifically for use with touchscreens. We conducted an exploratory user study of three existing graphical passwords on smart phones and tablets with 31 users. From this, we set our design goals for TMD to include addressing input accuracy issues without having to memorize images, while maintaining an appropriately secure password space. Design features include warp cells which allow TMD users to continuously draw their passwords across multiple layers in order to create more complex passwords than normally possible on a small screen. We compared the usability of TMD to Draw A Secret (DAS) on a tablet computer and a smart phone with 90 users. Results show that TMD improves memorability, addresses the input accuracy issues, and is preferred as a replacement for text passwords on mobile devices.},

However, there are no empirical studies that explore whether this is actually the case on an everyday basis. In this paper, we present the results of a real world user study across 21 days that was conducted to gather such insight; we compared the performance of Android-like patterns to personal identification numbers (PIN), both on smartphones, in a field study. The quantitative results indicate that PIN outperforms the pattern lock when comparing input speed and error rates. However, the qualitative results suggest that users tend to accept this and are still in favor of the pattern lock to a certain extent. For instance, it was rated better in terms of ease-of-use, feedback and likeability. Most interestingly, even though the pattern lock does not provide any undo or cancel functionality, it was rated significantly better than PIN in terms of error recovery; this provides insight into the relationship between error prevention and error recovery in user authentication.},

We found that users are generally concerned about insiders (e.g., friends) accessing their data on smartphones. Furthermore, we present the first evidence that the insider threat is a real problem impacting smartphone users. In particular, 12% of subjects reported a negative experience with unauthorized access. We also found that younger users are at higher risk of experiencing unauthorized access. Based on our results, we propose a stronger adversarial model that incorporates the insider threat. To better reflect users' concerns and risks, a stronger adversarial model must be considered during the design and evaluation of data protection systems and authentication methods for smartphones.},

abstract = {In this paper we compare one single-screen touch interaction with an automated teller machine (ATM) against two alternative second-screen ATM interactions using a smartphone. In an experimental laboratory study, those three ATM interactions were compared by means of workload (NASA-TLX), usability (SEQ, UMUX) and technology acceptance (selected TAM3-scales and additional scales for trust and security) in a randomized, controlled within-subjects design (n=24). In one smartphone ATM interaction the Personal Identification Number (PIN) was entered on the mobile phone, in the other smartphone ATM interaction the PIN was entered on the PIN-pad of the ATM. The results indicate that overall second-screen ATM interaction all interaction done on the mobile phone -- performed best.},

One particular research direction is the automatic context-aware adaptation of input modalities in multimodal mobile interfaces. We present existing adaptive multimodal mobile input solutions and position them within closely related research fields. Based on a detailed analysis of the state of the art, we propose eight design guidelines for adaptive multimodal mobile input solutions. The use of these guidelines is further illustrated through the design and development of an adaptive multimodal calendar application.},

abstract = {Automating tasks can make a smartphone easier to use and more battery efficient. However, currently little work has been done to help end-users to create such automations. In this paper, we explore an approach for automating smartphone tasks by demonstration. We have developed a mobile application called Keep Doing It that continuously records users' interactions with their smartphones. After users performed a task that they would like to automate, they can ask our application to create the automation based on their latest actions. Since users only have to use their smartphones, as they would naturally do, to demonstrate automations, we believe that our approach can lower the barrier for creating smartphone automations. Overall, an initial evaluation of the approach suggests that users would be willing to automate their phones by demonstration.},

IVRs are telephone-based, and similar to the world wide web in many aspects, but currently lack support for content sharing. Our approach uses 'audio codes' to let people share their call positions, and allows callers to hold their normal (low-end) handsets together to synchronise. The technique uses remote generation and recognition of audio codes to ensure that sharing is possible on any type of phone without the need for textual literacy or an internet connection. We begin by exploring existing user needs for sharing, then evaluate the technical robustness of our audio-based design. We demonstrate the value of the approach for voice service users over several separate studies--including an eight-month extended field deployment--then conclude with a discussion of future possibilities for such scenarios.},

Our work focuses on the Community Radio (CR) ecosystem in India, and through extensive field-studies we develop an in-depth understanding of the operations, strengths and challenges of a CR station. Based on this, we outline the design of a system that combines the content creation processes of a CR station with the mobile web. The system was evaluated with the users of a CR station in Bangalore over a month long deployment. Our key take-away is that the incorporation of a mobile web based delivery system can play a critical role in expanding the reach and consumption of community media in the target communities. Conversely, the relevance of CR content and role of radio jockeys (as trusted members of the community) can be a key driver in adoption of the mobile web in these communities. Together, such a hybrid approach points the way forward for more successful deployments of community media systems, and reveals several interesting HCI issues to be studied further.},

A key component of all branchless banking systems is a mechanism to provide receipts to users after each transaction as evidence for successful transaction completion. In this paper, we present results from a field study that explores user perceptions of different receipt delivery mechanisms in the context of a branchless banking system in India. Our study shows that users have an affinity for paper receipts: despite the provision of an SMS receipt functionality by the system developers and their discouragement of the use of paper, users have pro-actively initiated a practice of issuing and accepting paper receipts. Several users are aware of the security limitations of paper receipts but continue to use them because of their usability benefits. We conclude with design recommendations for receipt delivery systems in branchless banking.},

The study provides implications for the design of car-based collaborative media and considers how hands- and eyes-free natural interfaces could be tailored to the complexity of activities in the car and on the road.},

Via a survey of 398 enterprise workers, we find that people believe phone use interferes with meeting productivity and collaboration. While individuals tend to think that they make productive use of their own phones in meetings, they perceive others as using their phones for unrelated tasks. To help smartphones create a more collaborative meeting environment, we present an application that identifies and describes meeting attendees. We deploy the application to 114 people at real meetings, and find that users value being able to access information about the other people in the room, particularly when those people are unfamiliar. To prevent users from disengaging from the meeting while using their phones, we employ a gaming approach that asks trivia questions about the other attendees. We observe that gameplay focuses attention within the meeting context and sparks conversations. These findings suggest ways smartphone applications might help users engage with the people around them in enterprise environments, rather than removing them from their immediate social context.},

To this end, we present insights from two studies an interview study and a large-scale survey highlighting that while WhatsApp offers benefits such as cost, sense of community and immediacy, SMS is still considered a more reliable, privacy preserving technology for mobile communication.},

abstract = {In this paper, we investigate how smartphone applications, in particular web browsers, are used on mobile phones. Using a publicly available widget for smart phones, we recorded app usage and the phones' acceleration and orientation from 1,330 devices. Combining app usage and sensor data we derive the device's typical posture while different apps are used. Analyzing motion data shows that devices are moved more while messaging and navigation apps are used as opposed to browser and other common applications. The time distribution between landscape and portrait depicts that most of the landscape mode time is used for burst interaction (e.g., text entry), except for Media apps, which are mostly used in landscape mode. Additionally, we found that over 31% of our users use more than one web browser. Our analysis reveals that the duration of mobile browser sessions is longer by a factor of 1.5 when browsers are explicitly started through the system's launcher in comparison to being launched from within another app. Further, users switch back and forth between apps and web browsers, which suggest that a tight and smooth integration of web browsers with native apps can improve the overall usability. From our findings we derive design guidelines for app developers.},

We draw upon ethnographic field studies of collaborative hunting, where hunting dogs are tracked and their location made visible on digital maps. We discuss mobility of two different kinds. First, we refer to mobility as the practice of physical movements of hunters, dogs and prey. Second, we refer to the movement of symbolic objects on a digital map screen, i.e. screen mobility, and the interpretational work that the hunters do to make sense of it. Representations of motion on a screens, are of ongoing practical concern for the hunters. We show how they interpret such mobility in terms of accelerations, distance, trajectories and temporal alignments. The findings are used to revisit mobility theories and populate them with new notions to inspire design in broad domains.},

Device-specific models outperform unadapted user-specific models from different devices. However, with both user- and device-specific data, we demonstrate that our approach allows to combine this information to adapt models to the targeted device resulting in significant improvement. On average, adapted models improved accuracy by over 8%. We show that models can be obtained from a small number of touches (≈60). We also apply models to predict input-styles and identify users.},

Our techniques automatically determine the thumb's physical comfort zone and only require minimal thumb movement to reach distant targets on the edge of the screen. A controlled experiment shows that BezelSpace is significantly faster and more accurate. Moreover, both techniques are application-independent, and instantly accommodate either hand, left or right.},

The proposed device is accompanied by a new vocabulary of gestures and techniques that increase the expressiveness of the standard capacitive stylus. These techniques are: 1) detecting the orientation that the stylus is pointing to, 2) selecting colors using locations beyond screen boundaries, 3) recognizing different spinning gestures associated with different actions, 4) inferring the pressure being applied to the pen, and 5) identifying various pens associated with different operational modes. These techniques are achieved using commonly available smartphones that sense and analyze the magnetic field produced by a permanent magnet embedded in a standard capacitive stylus. This paper explores how magnets can be used to expand the design space of current pen interaction, and proposes a new technology to achieve such results.},

abstract = {Many current smartphones need to be recharged every day despite only average usage. This problem is intensified when phones need to track their location on a continuous basis. We provide a yet unavailable platform for accurately measuring the energy consumption of different hardware/software solutions comparing up to three variants in a mobile setting. We show that the accuracy of our system is similar to a fixed, commercial system but is especially useful to evaluate and optimize technology and algorithms that require the phone to be used on the go.},

We report how we used the Inspirational Bits method to inspire the design of novel NFC usage scenarios and application ideas for ATMs in a joint industry and academia project. We describe a set of small applications exposing different properties of NFC (henceforth, referred to as NFC-Bits) and how they informed and inspired collaborative design ideas for different use cases. The NFC-Bits reveal a broad range of NFC characteristics in a playful manner. We outline some of the developed use cases and describe features of MyPocketATM, an application stemmed from these ideas.},

abstract = {Reading is an activity that is not only informative or pleasurable, but can have significant social benefits. Especially in a family setting, it is part of the interaction between children and their parents, it helps create a bond between children and their grandparents, and even bring adults and their older parents closer. However, with families increasingly living or spending time in different locations or managing busy schedules that afford very little time together, the social opportunities enabled by reading are often lost. Furthermore, reading can be a challenge for older adults or for those with impaired eyesight. To address these problems, we are proposing ALLT -- an Accessible, Large-Print, Listening and Talking e-book. ALLT is a tablet-based e-reading application that enhances the capabilities of e-book readers through customizable and intelligent accessibility features. It provides support for asynchronous "reading together" by synchronizing the audio recording of one user with the text that is later read by another user. This addresses the needs of a variety of users, from visually impaired adults reading together with a loved one, to children being able to replay an interactive story previously read together with their grandparents. In this demo paper we present ALLT's features and detail how they support asynchronously reading together.},

Such a virtual transparency is usually implemented using video captured by a single camera rendered on the device's screen. This removes binocular-disparity, which may undermine user's ability to correctly estimate depth when seeing the world through the magic-lens. To confirm such an assumption this paper presents a qualitative user study that compares a magic-lens implemented on a mobile phone and a transparent glass replica. Observational results and questionnaire analysis indicate that binocular-disparity may play a significant role in participants' depth perception. These promising results led to the subsequent implementation of a stereoscopic magic-lens prototype on a commercially available mobile device.},

abstract = {Handheld Augmented Reality (AR) is often presented using the magic-lens paradigm in which a magic-lens is a transparent interface. Such transparency is usually implemented by rendering camera captured video on the device's screen. The transparency quality is limited by the video stream quality which may be affected by: unfocused camera lens, poor lighting conditions and limited video stream resolution. All these factors may reduce the readability of the AR scene. To address quality of rendering and increase scene readability, this paper presents an enhanced virtual transparency solution where segments of the scene are replaced by high definition digital content. The proposed enhanced virtual transparency isdemonstrated through the design of a digital magnifying glass which has been implemented on of-the-shelf mobile phone.},

The validation is done using some basic scenarios in which the users interact with various services available on the street. The user interface elements are represented by AR anchored objects (still pictures) and floating objects that are giving visual cues to where services are available. The users are aided in their actions by freezing the user interface when the device is down tilted so that they could easily manipulate the objects.},

In order to evaluate operability, we conducted a user experiment: a time trial for target selection. The subjects completed the task with the proposed controller in 44% less time than with a conventional wireless mouse. We confirmed that the proposed method can reliably follow finger gestures.},

abstract = {Interaction design for mobile applications is challenging due to the diversity of technologies and devices. In addition, the now ubiquitous multi-touch screens demand novel and engaging interface metaphors. In this paper, we report insights and three practical results from a workshop with undergraduate students. The aim was to experiment with new technologies by providing a set of creativity techniques for ideation. By tackling interaction design both for tablets and smartphones, flexible interface metaphors were developed.},

abstract = {This paper presents the motivation, design, and pilot evaluation of CountMeIn, a pervasive collaborative game to improve the waiting time experience (e.g., waiting for a train, or traffic light to turn green). We tested two versions of CountMeIn, an NFC-based and touchscreen version in a small pilot study. Our early results showed that the NFC-based version increases collaboration, and was overall more positively perceived than the touchscreen version. We discuss the challenges ahead in deploying CountMeIn in a real-world setting.},

abstract = {In this paper, we present results from an ongoing participatory design research project that focuses on the design and evaluation of a tagging-system and corresponding visualizations to support actors and visitors of an urban gardening project. The contributions of this work are threefold. First, it addresses the yet underexplored field of integrating context information beyond location and time into mobile tagging systems and folksonomies. Second, it suggests novel visualizations to explore tagged data and folksonomies beyond tag clouds and simple map representations on mobile phones. And third, it gives novel insights into supporting the embedded practices of a DIY (Do-It-Yourself) urban gardening community with interactive systems based on ethnographic fieldwork and participatory design.},
