SensingSam Ryu, Do Hyong Koh, Dongseok Ryu · 2011
In this work, we examined a touchless mouse, which is a Human-Machine Interface (HMI) device for non-contact gesture inputs to a computer system. The touchless or T-less mouse is used by moving a finger without touching any device or surface. We evaluated it according to the guidelines and testing procedures for evaluating computer pointing devices. Via data collection and statistical techniques, the Tless mouse was compared to a conventional mouse. The results indicated that the average completion time with the T-less mouse is longer than that with a conventional mouse. The number of errors with the T-less mouse were not significantly higher than that with a conventional mouse. A majority of the participants indicated that the T-less mouse could be a useful alternative in special situations in which a conventional mouse cannot be used.
