Design of an armband type contact-free space input device for human-machine interface

In this paper, the design of an armband type noncontact space input for human-machine interface is presented. Demand for a non-contact type input system has been increasing with the development of large-display technology. One of the non-contact type input system is a system based on gesture recognition. Unlike a glove type device, an armband device type does not constrain finger movements. We designed two different-types of armband space input systems for user interface. One is an arm band type space input system that uses arm movement and finger actions; the other is an armband type space input system by using arm movement and wrist snap actions.
