Mobile devices offer great opportunities in the field of collaborative learning. They are especially interesting in their ability to provide digital information while still supporting social interactions between group members, which are essential elements of coordinated and shared activities. However, in truly mobile conditions, e.g. outdoors, the high variability of groups spatial configurations can potentially modify coordination mechanisms. We designed and tested an orienteering mobile learning game to better understand how device use shaped collaboration in highly mobile conditions. The study involved four groups of three students all equipped with tablets. We focused our analysis on the relationship between participants' arrangements (F-formations), their device usage and coordination mechanisms (i.e. awareness, regulation, information sharing, and discussion). Our results emphasize the importance of considering the transitions between arrangements more than F-formations per se. We discuss the implications of these findings for the design and analysis of mobile collaborative activities.

A key problem in the area of citizen engagement is to make people aware of opportunities to participate and to motivate them to take action. We propose an approach that uses geofences and proactive notifications on mobile devices to raise citizen awareness of engagement opportunities in situ and to trigger the exploration of these opportunities. Notifications are automatically triggered in the near vicinity of engagement opportunities based on space, time, and user preferences. We conducted two user studies to investigate our approach. A field-based study revealed specific usage patterns and motivational aspects of the situated discovery of engagement opportunities. A lab-based comparison study investigated the pragmatic and hedonistic qualities of our application. Results indicate that users prefer to be informed in situ even when they do not necessarily interact with notifications straight away.

Persons that suffered from a cardiac disease are often recommended to integrate a sufficient level of physical exercise in their daily life. Initially, cardiac rehabilitation takes place in a closely monitored setting in a hospital or a rehabilitation center. Sustaining the effort once the patient has left the ambulatory, supervised environment is a challenge, and drop-out rates are high. Emerging approaches such as telemonitoring and telerehabilitation have been proven to show the potential to support the cardiac patient in adhering to the advised physical exercise. However, most telerehabilitation solutions only support a limited range of physical exercise, such as step-counting during walking. We propose BoB (Back on Bike), a mobile application that guides cardiac patients while cycling. Design choices are explained according to three pillars: ease of use, reduce fear, and direct and indirect motivation. In this paper, we report the results from a field study with cardiac patients.
患有心脏病的人经常被建议在日常生活中进行足够的体育锻炼。最初，心脏康复是在医院或康复中心的密切监测环境中进行的。一旦病人离开了门诊、有监督的环境，维持这种努力是一个挑战，而且辍学率很高。诸如远程监测和远程康复等新兴方法已被证明具有支持心脏病患者坚持建议的体育锻炼的潜力。然而，大多数远程康复解决方案只支持有限范围的体育锻炼，例如步行时的步数。我们推荐BoB (Back on Bike)，这是一个指导心脏病患者骑车的移动应用程序。设计选择是根据三个支柱来解释的:易用性，减少恐惧，直接和间接动机。在本文中，我们报告了对心脏病患者进行实地研究的结果。

In order to navigate through the world, people who are blind and visually impaired typically use maps through either textual directions or tactile printouts. However, visual maps on a touchscreen are not accessible to this population. Two prototypes were designed to test users' ability to trace graphical lines and directions through maps on a touchscreen using haptic feedback from an Android smart watch and tablet. With the first prototype, we show that blind and visually impaired users had lower threshold than sighted users for determining the distance between two lines on a touchscreen, suggesting their enhanced ability to form representations of spatial distance from tactile vibrational cues. With the second prototype, we show that it is feasible for blind and visually impaired users to follow directions through graphical maps based on vibrational cues. We believe these results show that our prototypes have the potential to be effective in real-world applications.

The rise of smartwatches calls for efficient, convenient and suitable text input methods for these small computers. The minuscule size of these screens brings many challenges on how to interact with these devices. Keyboard design requires optimization for these small screens to provide a good user experience and fast text entry method on these devices. We introduce SwipeKey, a text input method that uses swipe directions to allow multiple inputs per button and thus allows for an increase in the effective size of input buttons. We have conducted thorough experiments optimizing SwipeKey to create a fast, low-error, and easy to learn soft keyboard for smartwatches. These benefits result from having a keyboard that emphasizes the use of swipe motions. Our user study results show that with a specific combination of swipe directions and corresponding button size, SwipeKey users achieved a speed of 11 in words per minute (WPM), a 53% improvement from baseline (7.2 in WPM) and dramatically decreased character error rate (CER) from the baseline of 10% down to 3.4%.

While HCI for development (HCI4D) research has typically focused on technological practices of poor and low-literate communities, little research has addressed how technology literate individuals living in a poor infrastructure environment use technology. Our work fills this gap by focusing on Lebanon, a country with longstanding political instability, and the wayfinding issues there stemming from missing street signs and names, a poor road infrastructure, and a non-standardized addressing system. We examine the relationship between technology literate individuals' navigation and direction giving strategies and their usage of current digital navigation aids. Drawing on an interview study (N=12) and a web survey (N=85), our findings show that while these individuals rely on mapping services and WhatsApp's share location feature to aid wayfinding, many technical and cultural problems persist that are currently resolved through social querying. We discuss our results in light of problems that any map user encounters in poor infrastructure environments.
