Pointing in the air: Measuring the effect of hand selection strategies on performance and effort

Abstract

The research presented in this paper aims at measuring the effect of selection strategies on free-hand pointing performance and effort. Different evaluations are presented which shows that the selection strategies and the feedback do influence the pointing performance. In the main evaluation presented in this paper, three selection strategies, namely dwell, thumb and pinching, are compared. There was no winning selection strategy, although there was a significant effect of the selection strategies on the pointing performance. Further, the paper shows that it is not enough to compare only the performance of the user, but also the effort, comfort and the selection errors must be taken into account. © 2013 Springer-Verlag.
