Interactions with high volume complex three-dimensional data using traditional two-dimensional computer interfaces have, historically, been inefficient and restrictive. However, during the past decade, virtual reality (VR) has presented a new paradigm for human-computer interaction. This paper presents a VR human-computer interface system, which aims at providing a solution to the human-computer interaction problems present in today’s computer-aided design (CAD) software applications. A data glove device is used as a 3D interface for CAD model manipulation in a virtual design space. To make the visualization more realistic, real-time active stereo vision is provided using LCD shutter glasses. To determine the ease of use and intuitiveness of the interface, a human subject study was conducted for performing standard CAD manipulation tasks. Analysis results and technical issues are also presented and discussed.
