Direct Manipulation Video Navigation (DMVN) systems allow a user to directly drag an object of interest along its motion trajectory and have been shown effective for space-centric video browsing tasks. This paper designs touch-based interface techniques to support DMVN on touchscreen devices. While touch screens can suit DMVN systems naturally and enhance the directness during video navigation, the fat finger problems, such as precise selection and occlusion handling, must be properly addressed. In this paper, we discuss the effect of the fat finger problems on DMVN and develop three touch-based object dragging techniques for DMVN on touch screens, namely Offset Drag, Window Drag, and Drag Anywhere. We conduct user studies to evaluate our techniques as well as two baseline solutions on a smartphone and a desktop touch screen. Our studies show that two of our techniques can support DMVN on touch screen devices well and perform better than the baseline solutions.

Leading practice in mobile user experience design presents complex opportunities and challenges not always fully revealed in academic exploration and research. Addressing users with cultural and behavioural differences; understanding economic imbalances and wide demographic ranges amongst individuals and networks; including ethical considerations such as right to privacy and confidentiality, authorship, and transparency; perception and cognition; larger sustainability concerns; and understanding often ignored biases within the client group - these many factors define the contemporary user experience design landscape. How can we create a space for innovation that takes these constraints and people's context and aspirations into account? Mark Vanderbeeken will illustrate these challenges with examples from Experientia's practice, particularly through a project they recently conducted with Intel.

The need for text entry on smartphones and other touch-screen devices is key for many tasks and also a key factor in the usability of these devices. Physical and cognitive issues associated with age can aggravate the task of text entry for older adults. Technological exclusion due to low usability can present a significant problem both for social and ongoing business-related tasks with older adults. This paper investigates a new touch-screen keyboard design for older adults that combines the familiar QWERTY keyboard layout with physical gesture. User studies with older adults showed our keyboard reduced miss-taps, but was slower to use, and raised issues for further research.

Personal digital technologies have become the tools of reproduction for personal narration and broad cultural critique. Mobile social media enables individuals to function as storytellers and public commentators, with practices that offer an explicit engagement between people, places, and things. Mobile technologies and mapping tools enable direct connection to place, involving local communities and public dissemination. Mobile narratives and their creators can also make a larger contribution to collective memories of place, speaking back to aspects of culture at large.

It is important to recognize emergency responders? needs during emergency response to workplace incidents in order to propose solutions to facilitate responders? tasks and resolve incidents in a timely manner. To understand emergency response procedures involved in workplace incidents, we interviewed McGill Safety personnel. We identify potential areas of improvement in their procedures, which help us to shape research objectives. We then propose methods to address these objectives. We focus our investigation on a spill scenario and briefly describe our mobile solution to assist in this use context.

Protective barriers are often deployed to safely guide sea turtle hatchlings to the ocean but the barriers are contentious for they impede foot and vehicle traffic of beach users. Our goal is to develop a wireless system that can detect sea turtle hatching to enable "just in time deployment" of barriers, and notify tourists so they can watch sea turtles emerge from nests, generating awareness and compassion for these endangered species. We report on the development of a sensor and data acquisition system capable of detecting nest hatching activity in the harsh environment of a beach, including sensor selection, wireless networking, low-power design, data processing and environmental packaging. Field tests confirm the suitability of a low-cost low-power three-axis accelerometer and mobile networks for detecting and remotely communicating sea turtle hatching activity.

Biometric authentication relies on an individual's inner characteristics and traits. We propose an active authentication system on a mobile device that relies on two biometric modalities: 3D gestures and face recognition. The novelty of our approach is to combine 3D gesture and face recognition in a nonintrusive and unconstrained environment; the active authentication system is running in the background while the user is performing his/her main task.

While wearable technologies are suitable for remotely controlling mobile devices, few studies have examined user preferences for one- or two-handed touch interaction with these wearables, especially when worn on the wrist and hand area. As these locations are recognized as socially acceptable and preferred by users, we ran a study of touch interaction to remotely control mobile devices. Our results suggest users prefer swipe gestures over touch gestures when interacting with wearables on the wrist or hand, and that users find both one- and two-handed interactions suitable for wearable remote controls.

Mobile phone applications have received intensive attention by marketers due to the high engagement of users and its positive persuasive impact on brand. However, how can companies get on the right track of designing branded apps? Little research has been done on the identification of the elements which can be used to design branded apps strategy. Our research aims to offer a design framework of branded apps by identifying constructs from the perspective of company, user and technology respectively. By evaluating 84 mobile apps from top 11 FMCG (Fast Moving Consumer Goods) brands, we examine the usage of mobile interaction, social interaction and brand interaction in current branded apps design.

Research has shown that traditional usability evaluation methods cannot be readily applied to the evaluation of native smartphone applications. This research investigates this issue by adapting two usability evaluation methods, applying each at different stages of the design life cycle. Both adapted methods, when combined as a framework, may help in the design of more usable native smartphone applications.
