Summary: Most activity-aware systems designed to support mobile workers in dynamic environments, such as hospitals or industrial plants, typically consider the use of mobile devices and large displays. However, we envision potential benefits of using ubiquitous micro-displays as support of mobile workers activities. Particularly, in this paper we show how the use of situated micro-displays, as a mechanism for embedding information into a physical environment, can contribute to improve the performance and experience of mobile workers in those scenarios. The article also describes the prototype of a micro-display network designed to support people performing spatially distributed activities. It also presents a user study that helps understand how the spatial distribution of situated micro-displays impacts on the mobile workers performance.

Summary: This study addresses the influences of Spanish teenagers' usage intensity of the Spanish online social networking site Tuenti on their psychological wellbeing. Tuenti is the social networking site that is most preferred and used by Spanish adolescents. Hypothesized relationships are analyzed by structural equation analysis in a sample of 344 Spanish adolescents aged 12 -- 17 with an online Tuenti profile. Teenagers' usage intensity of Tuenti was positively related to the degree of socializing on the social networking site. Furthermore, socializing on Tuenti had a significantly positive influence on teenagers' perception of wellbeing. This relationship was not direct, however, but mediated by the intervening variables of self-esteem and loneliness. Results confirmed that Tuenti has become a suitable platform for the development, consolidation and growth of Spanish teenagers' social relations. Contrary to some previous research pointing to a detrimental effect of SNS use on mental health and psychological wellbeing, the findings of this study are in line with those of a number of authors who suggest that SNS use may on the whole be positive for users, including most teenagers.

Summary: Mobile collaboration is required in several work scenarios, i.e. education, healthcare, business and disaster relief. The features and capabilities of the communication infrastructure used by mobile collaborative applications will influence the type of coordination and collaboration that can be supported in real work scenarios. Developers of these applications are typically unaware of the constraints the communication infrastructure imposes on the collaborative system. Therefore, this paper presents an experimental study of how ad-hoc networks can effectively support mobile collaborative work. The article analyzes several networking issues and it determines how they influence the collaborative work. The paper also presents the lessons learned and it provides recommendations to deal with the networking issues intrinsic to ad-hoc networks.

[5] USES OF EYE TRACKING TECHNOLOGY IN DESIGN POSTERS: Eye Tracking / Medina, Eliana / Cuddihy, Elisabeth / Goldberg, Eli / Ramey, Judith A. Proceedings of the Human Factors and Ergonomics Society 52nd Annual Meeting 2008-09-22 v.52 p.1574-1578

Summary: Eye tracking technology has caught the attention of designers who wish to better understand how users visually interact with products and technologies. Given the availability of eye tracking technologies, which are able to measure users' eye gaze on computer screens, designers and researchers can employ eye tracking to answer a very wide variety of questions about users' visual behavior, cognition, and visual attention strategies. Yet, commercial eye tracking software typically provides a limited number of out-of the-box analysis tools for understanding the massive amount of data generated during eye tracking sessions. This poster (1) surveys the range of questions that people have successfully asked using eye tracking technology and (2) summarizes how raw eye tracking data is transformed into higher-level constructs that are more appropriate for analysis and the kinds of analysis that can be performed. The goal of this poster is to help designers make more informed decisions when considering the use of eye tracking to aid them in design.

Summary: A major challenge for virtual reality (VR) interfaces is to provide realistic human interactions with the virtual world in more natural ways; one solution is to use a device called the VirtuSphere (VS). The VS provides a mechanism for walking in VR in semi-natural way; however, users have to adapt to walking in a moving platform, having limited visual feedback and integrating motion cues with physical responses. In this study we report on the challenges novice users of this virtual reality locomotion device encounter when performing navigation tasks in a virtual environment in two visual conditions (first-person and third-person viewpoint). We analyzed how performance, simulator sickness, and satisfaction vary under these two viewpoint conditions. We found that motion sickness and balance disturbance were more pronounced for the first-person viewpoint group than for the third-person group. However the first-person viewpoint group performed better and enjoyed the experience more than the third-person view group.
