Abstract:
Several interaction metaphors and techniques have been proposed to allow a
natural interaction in virtual environments. Usually all these techniques
are designed to be used with input devices such as wands, 3D mice or gloves.
However, the availability of a new generation of auto-stereoscopic displays
now makes it possible to exploit virtual experiences in new scenarios. In
this paper we propose a variation of the ray-casting technique suitable for
use with a standard mouse. With this proposed technique, users can move a 3D
cursor in the virtual world without worrying about the third dimension and
without losing the level of immersion provided by the 3D display.
