Two talks on Tangibles

Interacting with Multiple Displays Using Tangible Windows, Gestures and Gaze & Tangible Musical Interfaces

Speakers: Raimund Dachselt & Martin Kaltenbrunner

Everybody is welcome

TALK 1 - Prof. Raimund Dachselt: Interacting with Multiple Displays Using Tangible Windows, Gestures and Gaze


To find more efficient and user-friendly ways of exploring information spaces, we investigate natural interaction in multiple-display environments. In particular, tabletops and mobile devices are among the interactive surfaces which are operated by touch, gestures, pen or other types of tangible interaction. The talk will outline two avenues of current research. One is the usage of tangible magic lenses which elegantly unite input and output space. These are optically tracked, lightweight displays that provide intuitive spatial exploration of rich 2D and 3D datasets. By moving one or multiple hand-held magic lenses through the physical interaction volume, corresponding data is displayed, thus serving as a window into virtuality. Besides interaction WITH lenses, interaction techniques also include input directly ON the lenses by means of pen and touch and the usage of a head-coupled perspective. Another avenue of research is the multimodal interaction with large displays in the distance. Among others, the talk will introduce techniques for gaze-supported interaction. Thereby, the user's gaze is used in combination with multitouch input on mobile handhelds to provide easy ways of selecting, positioning and manipulating objects on remote displays.


Raimund Dachselt is university professor of computer science at Technische Universität Dresden (TUD), Germany, where he heads the Interactive Media Lab Dresden ( since April 2012. After studying computer science in Dresden and Glasgow, he joined the Multimedia Technology Group at TUD, where he received his PhD in 2004 in the area of interactive 3D graphics ( As a post-doctoral researcher and academic assistant in Dresden he conducted research on zoomable user interfaces and faceted browsing for personal information and media management. In 2007 Raimund started building up his own User Interface & Software Engineering group at the Otto-von-Guericke-University of Magdeburg as an assistant professor. In April 2011 he was appointed associate professor at the same university. His main research interests are novel visualization and interaction techniques for environments with multiple interactive displays and combined input modalities, among them multitouch and pen interaction as well as tangible and gaze-supported interaction. Dr. Dachselt is a member of the IEEE Computer Society, ACM SIGCHI and SIGMM. He has co-organized several international workshops and has extensively served as a program committee member, organizer and reviewer of international conferences and workshops. He is the European coordinator of the transatlantic exchange program LEIF between eight Canadian and European research institutions.

TALK 2 - Prof. Martin Kaltenbrunner: Tangible Musical Interfaces


In his talk Prof. Kaltenbrunner will outline the genre of Tangible Musical Interfaces in general and the Reactable in particular, including a hands-on demonstration of the present version of the instrument.


Martin Kaltenbrunner is Professor at the Interface Culture Lab at the University of Art and Design in Linz. Before his return to Austria he worked as researcher and lecturer at the Pompeu Fabra University in Barcelona, at the MIT Medialab Europe in Dublin, and further European universities. As co-founder of Reactable Systems he had been mainly responsible for the interaction design concepts behind the Reactable, a tangible modular synthesizer. The instrument has been shown at several international media art and music festivals, and was awarded with the Golden Nica for Digital Music, two D&AD Yellow Pencils and the Prize of the City of Barcelona. Kaltenbrunner mainly publishes in the context of human computer interaction conferences and his research on tangible interface tools has been employed for the realization of numerous artistic and scientific projects in that area.
