Finger in air: touch-less interaction on smartphone

Abstract

In this paper we present a vision based intuitive interaction method for smart mobile devices. It is based on markerless finger gesture detection which attempts to provide a 'natural user interface'. There is no additional hardware necessary for real-time finger gesture estimation. To evaluate the strengths and effectiveness of proposed method, we design two smart phone applications, namely circle menu application - provides user with graphics and smart phone's status information, and bouncing ball game- a finger gesture based bouncing ball application. The users interact with these applications using finger gestures through the smart phone's camera view, which trigger the interaction event and generate activity sequences for interactive buffers. Our preliminary user study evaluation demonstrates effectiveness and the social acceptability of proposed interaction approach.
