An evaluation of techniques for grabbing and manipulating remote objects in immersive virtual environments

Abstract

Grabbing and manipulating virtual objects is an important user interaction for immersive virtual environments. We present implementations and discussion of six techniques which allow manipulation of remote objects. A user study of these techniques was performed which revealed their characteristics and deficiencies, and led to the development of a new class of techniques. These hybrid techniques provide distinct advantages in terms of ease of use and efficiency because they consider the tasks of grabbing and manipulation separately.

This capability is desirable in many VR applications and is typically accomplished using ...
