In this article we present the findings of two ethnographic studies embedded into two broader projects on interactive television in the home environment. Based on previous research on the home context and inspired by ongoing trends around interactive television, we explored basic concepts, such as the extended home, and new interaction techniques, in(More)
Increasing use of mobile phones in leisure and communication with digital images are important and current issues in the field of telecommunications. However, little is known about how images would be used in leisure related communication. According to our experience field trials are the best way of studying it. In this paper, we describe a field-trial case(More)
This workshop addresses current needs in the games developers' community and games industry to evaluate the overall user experience of games. New forms of interaction techniques, like gestures, eye-tracking or even bio-physiological input and feedback present the limits of current evaluation methods for user experience, and even standard usability(More)
Online communities of different types have become an important part of the daily internet life of many people within the last couple of years. Both research and business have shown interest in studying the possibilities and risks related to these relatively new phenomena. Frequently discussed aspects that are tightly bound to online communities are their(More)
Tag clouds have become a frequently used interaction technique in the web. Recently several approaches to present tag clouds with the tags semantically clustered have been proposed. However, it remains unclear whether the expected gains in performance and advantages in interaction actually can be realized as no empirical evaluations of such approaches are(More)
This paper reports about a human-robot interaction field trial conducted with the autonomous mobile robot <i>ACE (Autonomous City Explorer)</i> in a public place, where the <i>ACE</i> robot needs the support of human passers-by to find its way to a target location. Since the robot does not possess any prior map knowledge or GPS support, it has to acquire(More)
This book chapter describes an approach of evaluating user experience in video games and advanced interaction games (tabletop games) by using heuristics. We provide a short overview of computer games with a focus on advanced interaction games and explain the concept of user-centred design for games. Furthermore we describe the history of heuristics for(More)
It can be argued that one of the main reasons for playing games is to achieve an emotional reaction of the player. To be surprised, happy, angry or anxious - to perceive different emotional states - is one of the main reasons to play games. The "Emotional Flowers" game harnesses the player's emotions as the primary means for the game interaction. Within the(More)
In order to support drivers to maintain a predefined driving speed, we introduce ChaseLight, an in-car system that uses a programmable LED stripe mounted along the A-pillar of a car. The chase light (i.e., stripes of adjacent LEDs that are turned on and off frequently to give the illusion of lights moving along the stripe) provides ambient feedback to the(More)
