Designing natural user interfaces for large surfaces

Abstract: A range of emerging technologies and applications enables more natural and human centered interfaces so that interacting with computers and content becomes more intuitive. This will be important as computing moves from the desktop to being embedded in objects, devices and locations around us and as our “desktop” and data are no longer device-dependent but follow us across multiple platforms and locations. The impact of Apple’s iPhone and an increasing number of multi-touch surfaces show that users' expectations about using these devices in their daily lives have increased. The reaction to these natural interface implementations has been very dramatic. With the increasing development of interactive walls, interactive tables, and multitouch devices, both companies and academics are evaluating their potential for wider use. These newly emerging form factors require novel human– computer interaction techniques which will be discussed in this presentation. My research goal is to design, develop, and evaluate natural user interfaces that will enable everyone, not just experts, to use large, interactive surfaces. In this talk, we will describe particular challenges and solutions for the design of tabletop and interactive wall environments that can be used for teaching and brainstorming in a more exciting and enjoyable way.

Short Bio: Michael Haller is a professor at the department of Interactive Media of the University of Applied Sciences Upper Austria (Hagenberg, Austria), head of the Media Interaction Lab (, head of the Austrian Research Center NiCE, and responsible for interactive computer graphics, human computer interaction, and augmented reality. His core areas of expertise are visualization and interaction. He received Dipl.-Ing. (1997), Dr. techn. (2001), and Habilitation (2007) degrees from Johannes Kepler University of Linz, Austria. His current focus is on innovative interaction techniques and interfaces for next generation working environments. Currently, he leads a team of over 15 researchers and students. In 2004, he received the Erwin Schrödinger fellowship award presented by the Austrian Science Fund for his visit at the Human Interaction Technology Laboratory (HITLabNZ), University of Canterbury (New Zealand), and the Integrated Media Systems Center (IMSC), University of Southern California (USA). The research output includes 17 journal papers and book chapters, and has been presented already in high quality academic conferences (ACM CHI, ACM UIST) and several demonstrations including ACM SIGGRAPH, Disney's New Technology Forum, and Ars Electronica Festival.

Scientific Visualization at the EMCL

Abstract: Visualization is the key element for exploration of numerical simulations and raises the impact of scientic computing in an interdisciplinary context. From the scientists workplace over high performance visualization installations to mobile devices, scientic visualization oers intuitive access to high performance computing. In the Engineering Mathematics and Computing Lab (EMCL) at the Karlsruhe Institute of Technology (KIT), new approaches are researched and developed, for innovative visualization concepts in the application areas of meteorology, biotechnology and energy research.

Short Bio: Sebastian Ritterbusch holds a M.Sc. in Applied Mathematics from the University of Massachusetts in Amherst, a Diploma in Techno-Mathematics and a Doctorate in Mathematics from the University of Karlsruhe. Since 2003, he is teaching and conducting research at the University of Karlsruhe and has received a distinguished teaching award of the state of Baden- Württemberg. Since 2009, he is the head of the Computing Laboratory for Scientic Visualization in the Engineering Mathematics and Computing Lab (EMCL) at the Karlsruhe Institute of Technology (KIT), where he is also managing an European EUREKA Eurostars project in the field of mobile visualization.

MR Application Development using the inVRs Framework

Abstract: To improve the development process of Virtual Environments (VEs) and Networked Virtual Environments (NVEs) the inVRs (interactive networked Virtual Reality system) framework provides a clearly structured approach for the design of highly interactive and responsive NVEs. The latest version has been extended to supporting Augmented Reality rendering which now allows the framework to cover the whole MR continuum. It consists of three independent modules, one for interaction, one for navigation, and one for network communication, two interface layers to support a variety of output and input devices, and a system core which stores and manages the state of the VE. Additional tools provide a valuable extension to the framework and support fast prototyping for MR application development.
