An evaluation of touchless hand gestural interaction for pointing tasks with preferred and non-preferred hands

Abstract

Performance evaluations of touchless gestural interaction are generally done by benchmarking pointing performance against existing interactive devices, requiring the use of user's preferred hand. However, as there is no reason for this interaction to be limited to only one hand, evaluation should rightfully consider both hands. In this paper we evaluate the performance of touchless gestural interaction for pointer manipulation with both the preferred and non-preferred hands. This interaction is benchmarked against the mouse and the touchpad with a multidirectional task. We compared the performance between all devices, improvement in performance between 2 rounds, and the degradation of performance between hands. The results show the mouse has no performance increase between rounds but high degradation across hands, the touchpad has medium performance increase and medium degradation, and gestural interaction has the highest performance increase and the lowest degradation between hands.
