techniques with the ability of the human visual-brain system and the haptic-motoric system to explore and analyze complex data comprehensively. This kind of visualization merges several aspects of different research areas, such as In-symbolic information sources, in order to help users understand and analyze such data. For most practical applications,(More)
Input from the lower body in human-computer interfaces can be beneficial , enjoyable and even entertaining when users are expected to perform tasks simultaneously. Users can navigate a virtual (game) world or even an (empirical) dataset while having their hands free to issue commands. We compared the Wii Balance Board to a hand-held Wiimote for navigating a(More)
The hands are highly suited to interact with large public displays. It is, however, not apparent which gestures come naturally for easy and robust use of the interface. We first explored how uninstructed users gesture when asked to perform basic tasks. Our subjects gestured with great similarity and readily produced gestures they had seen before; not(More)
FeelSound is a multi-user application for collaboratively composing music in an entertaining way. Up to four composers can jointly create acoustic music on a top-projection multi-touch sensitive table. The notes of an acoustic instrument are represented on a harmonic table and, by drawing shapes on an instrument's table, a sample is created. These samples(More)
In this paper we discuss an approach towards passively observing students in a driving simulator. The goal is to enhance the learning experience for students taking lessons in this simulator. To this end, a virtual driving instructor is provided with added information consisting of the gaze behavior of its student. The gaze behavior is defined by estimated(More)
