HUMAN PERFORMANCE EVALUATION OF MANIPULATION
SCHEMES IN VIRTUAL ENVIRONMENTS
Proceedings of VRAIS'93: First IEEE Virtual Reality Annual International
Seattle, Sept 1993.
This paper presents the results of one of the first experiments in a research
programme aimed at systematically investigating manipulation schemes
for spatial input, from a human factors point of view. A three dimensional
design space model is proposed as a framework for such investigations and
four options within this model are tested in a 6 degree-of-freedom target
acquisition task within a virtual environment. Experimental results indicate
strong performance advantages for isometric sensing combined with rate
control and for isotonic sensing combined with position control. A strong
interaction between sensing mode and mapping function is found. The
findings are discussed in relation to the literature on spatial manipulation.
