Two-handed and one-handed techniques for precise and efficient manipulation in immersive virtual environments

Abstract

Two-handed control techniques for precisely and efficiently manipulating a virtual 3D object by hand in an immersive virtual reality environment are proposed. In addition, one-handed and two-handed techniques are described and comparatively evaluated. The techniques are used to precisely control and efficiently adjust an object with the speed of one hand or the distance between both hands. The controlled adjustments are actually position and viewpoint adjustments. The results from experimental evaluations show that two-handed control methods that are used to make the position and viewpoint adjustments are the best, but the simultaneous use of both one-handed and two-handed control techniques does not necessarily improve the usability. © Springer-Verlag Berlin Heidelberg 2008.
