The DabR - A multitouch system for intuitive 3D scene navigation

Abstract

Multi-touch capable displays are one of the central emerging technologies in Human Computer Interfaces and many commercial applications like the Apple iPhone or the Microsoft Surface already show the benefit of this interaction technique. But most of the applications are limited to 2D interaction and only little effort has been spent on intuitive 3D interaction techniques. Since 3D scene navigation is a central aspect of 3DTV applications we present easy and intuitive multi-touch gestures to control a virtual 3D camera. These gestures were implemented on The DabR - a complete and robust multi-touch system designed at our institute. The underlying computer vision algorithms to cover the tracking of the users' fingers are GPU accelerated to ensure very low latency for the interaction.
