In this paper, the design of an armband-type non-touch space input mouse for human computer interface is presented. Demand for a non-touch type input system has been increasing with the development of large-display technology. One of the non-touch type input system is a system based on gesture recognition. There is a lot of research on gesture recognition systems based on vision, but the presented device has advantages in terms of accuracy. The globe type input system is already developed, but the users do not want restrictions on finger actions. Unlike a glove type device, an armband device type does not constrain finger movements. We designed an armband- type space input mouse by using arm movement and wrist gesture actions.

A variety of research for input device is being conducted [1]-[4]. Demand for a non-touch type input system has been increasing with the development of large-display technology. One of the non-touch type input system is a system based on gesture recognition. There is a lot of research on gesture recognition systems based on vision, but the presented device has advantages in terms of accuracy. Users would like to control devices by using small motions. The globe type input system is already developed, but the users do not want restrictions on finger actions. Unlike a glove type device, an armband device type does not constrain finger movements. In this paper, the design of an armband-type non-contact space input for human computer interface is presented. An armband-type non-touch 3D space input mouse is I/O interface technology for manipulating various devices using a user's arm/wrist gestures. The user wears the device on the wrist in contactless 3D space environment, such as a large smart interactive TV or HMD. We designed an armband-type space input mouse by using arm movement and wrist gestures. The practical considerations of an armband-type non-touch space input system are the contactless interface based on multi-sensor; the natural behavior of users such as arm, and wrist motion recognition; and convenience, such as small size unrestricted motions.
