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 T-less 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.
