Human interface based on finger gesture recognition using omni-directional image sensor

A camera is not a special device for a personal computer. An omni-directional image sensor is a camera that can capture a surrounding image in every direction at a time by using a convex mirror and a video camera. When we grab the omni-directional sensor, the camera captures image of fingers. We propose a human interface based on finger gesture recognition using an omni-directional image sensor. By grabbing the omni-directional image sensor, a user can input commands to the computer. The finger image provides the number of fingers, their area, and their position. The proposed interface recognizes the operations of pushing, pulling, rotating and translating the change of these finger parameters. We implemented the interface for operation of a virtual object using finger gestures to a prototype system.
