The latest in the most popular head-to-head fighting video series, Super Street Fighter IV by Capcom, now features spectating functionality. Coupled with audio chat, players can both watch and participate in matches with anyone in the world. We describe a video analysis of over 36 hours of gameplay in SSF4. Our results show that players can deftly structure audio when spectating to transform gameplay in SSF4.

Prototyping is a well-studied activity for interaction designers, but its role in computer game design is relatively unexplored. The aim of this study is to shed light on prototyping in game design. Interviews were conducted with 27 game designers. The empirical data was structured using qualitative content analysis and analysed using the design version of The Activity Checklist. The analysis indicated that six categories of the checklist were significant for the data obtained. These categories are presented in relation to the data. The roles of externalization and internalization are specifically highlighted.

We present a new technique for combining linear movement, rotation and vision tracking for two-handed motion tracking and provide links to open source tools and applications for next generation 6DOF motion tracking and visualisation of exertion games.

This paper explores techniques to manipulate remote 3D objects on direct-touch tabletops using absolute and relative mapping modes. A user study was conducted to compare absolute and relative mappings in support of a rotation task.

We present a study investigating the performance in a 3D object manipulation task with a mouse and a dedicated input device (SpaceNavigator). Previous research delivered ambiguous results about the performance in different 3D tasks. Therefore we used placement (only translation) as well as docking (translation and rotation) tasks.

We contribute a novel model for the embodied navigation of a-priori unknown information spaces with spatially-aware displays. The model is inspired by physiological aspects of the human body. We have empirically validated the model in a controlled experiment with 32 participants.

Our research aims at helping families work together to achieve a healthier lifestyle, increasing their awareness of what they currently do and what they could do differently. We built a prototype collaborative platform for families to see if we could facilitate health discussions and encourage supportive behaviour within the family.

This paper presents a software tool that was created to help care staff become more familiar with a person with dementia in a limited timeframe. A study was conducted with three care home managers to collect initial response, usefulness and usability ratings of the software in a care home environment.

Distributed Cognition (DCog) has been proposed as being a better approach to analyzing healthcare work than traditional cognitive approaches, due to the collaborative nature of healthcare work. This study sought to explore this by applying two DCog frameworks, DiCoT and the Resources Model, to the analysis of infusion pump use in an Intensive Care Unit

In this paper we explore the notion of creating personally evocative collections of content from publicly available material.
