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)
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)
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)
FeelSound is a multi-user, multi-touch application that aims to collaboratively compose, in an entertaining way, acoustic music. Simultaneous input by each of up to four users enables collaborative composing. This process as well as the resulting music are entertaining. Sensor-packed intelligent environments form the target location of FeelSound, varying(More)
Large displays are highly suited to support discussions in empirical science. Such displays can display project results on a large digital surface to feed the discussion. This paper describes our approach to closely involve multidisciplinary omics scientists in the design of an intuitive display control through hand gestures. This interface is based upon a(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)
