Magic Ring: a self-contained gesture input device on finger

Control and Communication in the computing environment with diverse equipment could be clumsy, obtrusive, and frustrating even just for finding the right input device or getting familiar with the input interface. In this paper, we present Magic Ring (MR), a finger ring shape input device using inertial sensor to detect the subtle finger gestures and routine daily activities. As a self-contained, always-available, and hands-free input device, we believe that MR will enable diverse applications in the intelligent computing environment. In this demonstration, we will show a prototype design of MR and three proof-of-concept application systems: a remote controller to control the electrical appliance like TV, radio, and lamp using simple finger gestures; a natural communication tools to chat using the simplified sign languages; a daily activity tracker to record daily activities such as room cleaning, eating, cooking, writing with only one MR on the index finger.
