Comparative Analysis of Interaction Techniques in Virtual Reality

Abstract

Virtual Reality is an emerging breed in technology. It is gaining an increasing amount of interest and considerable work is being done on it recently. A virtual environment without any user interaction can quickly lose users' interest. To make virtual environment more captivating, user interaction with virtual world is important. The paper reviews recent technologies and methods of human-computer interaction in the virtual environment. First a thorough examination of recent work done on different ways of interacting with virtual environment was carried out. Based on this review a variety of virtual reality interaction techniques were identified and then categorized into four major categories namely, haptic devices, gesture recognition, brain-computer interface, and gaze-based interaction. These techniques were evaluated against certain predefined parameter. An extensive analysis of the different techniques and their literature has led to a consolidated review that is presented in this paper.

Copyright Protection of 3D Digitized Sculptures by Use of Haptic Device for Adding Local-Imperceptible Bumps

“…In recent years, haptic devices have advanced significantly, so there are so-called haptic hands. A haptic hand is a robotic hand whose design is simplified and created to imitate the human hand and provide haptic force feedback in all joints at the moment of contact with an object in the virtual environment [42,[50][51][52][53][54][55][56][57][58][59]. Authors feel that using a haptic hand for digital sculpting and adding protection would allow for a more realistic sculpting experience than what was achieved with the haptic device used in this research.…”
