Designing in virtual reality (DesIRe): A gesture-based interface

In this paper, our purpose is to focus on detection of dynamic gestures and find the thresholds to detect gestures for a gesturebased system, DesIRe (DESigning In virtual REality). DesIRe treats virtual reality as a platform of virtual clay and allows realtime dynamic interaction with an object to perform a number of design operations. We developed an interface using a stereoscopic display environment and combining elements of gesture recognition and motion capture. The system architecture of DesIRe include following components: Vizard Virtual Reality Toolkit, an immersive projection system (VISOR), an optical tracking system (specifically the PPT system and the in-house gesture recognition software), and Data Input System (a data glove). In DesIRe, the user has control of a hand-shaped cursor which is guided by a single infrared LED and linked to the data glove finger states and orientation in order to provide an immediate, visual feedback. In this paper, we present an approach to represent the finger states using binary digits in gesture detection and demonstrate the thresholds. We found that thresholds are glove specific.
