Interactive Manipulation in Virtual Environments

摘要

Virtual Reality Environments need to integrate effective techniques to manipulate objects. The interaction covers the haptic and visual aids in the virtual environments. Haptic interfaces use can improve the interaction helping to identify the intention of the user to adapt the visual interface to help in the manipulation operation. Also, when haptic interfaces integrate physical behaviour simulation, the users have more feedback to interact with other users. The aim is to briefly describe these techniques as well as some algorithms to predict and automate some of the interaction processes when an object is manipulated. A combination of haptic devices and algorithms, depending on the application desired can give an important support for better interaction. This paper presents an overview of such techniques.
