Three-Dimensional Graphics and Realism – Virtual Reality

Virtual traveling technique in virtual environment (VE) is one of the interaction techniques. It aids user to travel freely in VE. Even though there are a lot of virtual traveling techniques, all is only based on the way of specifying the target position. In this paper, we proposed new travel technique called Forve which are allowed to specify the desired velocity and acceleration of travel. We evaluate its usefulness by conducting quality factors analysis. Subjects are required to travel through virtual corridors until reaching the end of the corridor. All subjects use various velocity control techniques while using the pointing technique for specifying the target position. Results indicate that the force-based technique is more efficient for specifying velocity and acceleration in VE
