Development of an interface based on special feature of iris

Abstract

This paper proposed an intuitive interface based on blinking input with non-contact state. Fast of all, user's eyes taken to the computer was detected by the Haar-like feature amount. The position of user's iris was estimated by varying the threshold in the binalization procedure. Here, we utilized the blink actions as an input interface and the open/close state were judged by the area of the iris. When the area was decreased, the system recognized that the user closed the eye. This constructed system was applied to the operation for the communication-aid.
