SMSlingshot a shared encounter in urban space

Interaction design is increasingly situated beyond the desktop and demands new approaches, if it is made for Urban Space. Public and semi-public spaces add new challenges in terms of interaction theory, technology and sociology. SMSlingshot is an interactive unban installation (also named a Shared Encounter) and research vehicle that helps to explore these new challenges

Desktop-Gluey: Augmenting Desktop Environments with Wearable Devices

International audienceUpcoming consumer-ready head-worn displays (HWDs) can play a central role in unifying the interaction experience in Distributed display environments (DDEs). We recently implemented Gluey, a HWD system that 'glues' together the input mechanisms across a display ecosystem to facilitate content migration and seamless interaction across multiple, co-located devices. Gluey can minimize device switching costs, opening new possibilities and scenarios for multi-device interaction. In this paper, we propose Desktop-Gluey, a system to augment situated desktop environments, allowing users to extend the physical displays in their environment, organize information in spatial layouts, and 'carry' desktop content with them. We extend this metaphor beyond the desktop to provide 'anywhere and anytime' support for mobile and collaborative interactions

Human-Computer Interaction in Mobile Context : A Cognitive Resources Perspective

Human-computer interaction is currently shifting its focus from desktop-based interaction to interaction with "beyond the desktop", which is embedded into everyday activities. In order to support users more elegantly, these mobile, wearable, and ubiquitous computing devices are envisioned to adapt inte lligently to their context. Thus far, however, the mobile use contexts per se have received attention, as most research has been technology-driven. Drawing from cognitive psychology, user modeling in human-computer interaction, and ethnomethodology, a framework is put forward here to analyse mobile use situations from the point of view of resource competition. The framework assumes that mobility is inherently multitasking and easily leads to competition for cognitive and other human resources. This "cognitive resource competition" framework is elaborated and associated with the psychological principles of capacity and multitasking. It looks at the typical social, interactional, cognitive, and physical tasks in mobility, relates them to the typical cognitive resources they compete for, and, based on known capacities of cognitive faculties, pinpoints restrictions and resources for action that can emerge in a given mobile situation. It is argued that the approach is useful for identifying the perceptual, attentional, and cognitive capabilities of a user in a mobile situation. The approach has implications for the design and innovation of intelligent, context-sensitive user interfaces and services. Furthermore, a practical method for making human resources visible in a design session is proposed and evaluated

3D Interaction Techniques for Virtual Shopping : design and preliminary study

Virtual Reality is now recognized as a powerful tool for the assessment and rehabilitation of both motor and cognitive impairments. In this context, effective Virtual Environments (VEs) that simulate everyday tasks must be proposed. We have developed a virtual supermarket (VS) in which the user can explore and collect various items using a shopping cart. Four interaction techniques have been designed and compared in terms of usability, performance and workload with healthy volunteer participants. These techniques go beyond the desktop paradigm by offering a more immersive and intuitive way of interaction. Results showed that participants were more efficient in terms of performance (completion time and travelled distance) using the game-pad rather than using full body gestures. However, they had more fun performing the task under these conditions

Workshop on Desktop Search

The first SIGIR workshop on Desktop Search was held on 23rd July 2010 in Geneva, Switzerland. The workshop consisted of 2 industrial keynotes, 10 paper presentations in a combination of oral and poster format and several discussion sessions. This report presents an overview of the scope and contents of the workshop and outlines the major outcomes

Establishing the design knowledge for emerging interaction platforms

While awaiting a variety of innovative interactive products and services to appear in the market in the near future such as interactive tabletops, interactive TVs, public multi-touch walls, and other embedded appliances, this paper calls for preparation for the arrival of such interactive platforms based on their interactivity. We advocate studying, understanding and establishing the foundation for interaction characteristics and affordances and design implications for these platforms which we know will soon emerge and penetrate our everyday lives. We review some of the archetypal interaction platform categories of the future and highlight the current status of the design knowledge-base accumulated to date and the current rate of growth for each of these. We use example designs illustrating design issues and considerations based on the authors’ 12-year experience in pioneering novel applications in various forms and styles
