One-Finger Interaction for Ubiquitous Environment

Abstract

We propose a new interaction technique called “One-finger Interaction” for the ubiquitous environment in a home. One-finger Interaction is an interaction technique for performing various operations through movement of the index finger. It is possible for the user to operate from a distance. Additionally, because the user uses only a LED device and fingertip recognition is very sensitive, this method can be readily used in various environments. The user can also change the menu according to personal preferences and applications. We developed two prototype interfaces for One finger Interaction. One is an interface that allows one to execute operations by moving one’s fingertip and crossing icons. The other is one in which the user selects a rough position of the menu by the general direction of movement of one’s fingertip, then selects a specific position by moving one’s finger in a circular fashion. These interfaces allow the user to perform various operations by movement of the fingertip. Also, because it is possible to move from the end of one operation to the next action instantaneously, the user can operate menus continuously.
