Embedded hand sensor technology recognizes faces

Omron Corp. has developed a hand gesture recognition technology that, unlike conventional gesture recognition technologies, does not need a trigger motion such as waving a hand to start the recognition process. The technology is said to be capable of simultaneously recognizing the position, shape and motion of a person's hand or finger from a moving image.

Combined with the company's facial image sensing technology, gesture recognition can be started automatically based on the analysis of interrelation between the position or direction of the face and the hand shape or position.

The technology allows users to control devices in a natural manner, such as operating a TV set with hand movements or releasing the shutter of a camera via a hand gesture. It uses techniques such as statistical classification of a large number of existing images and model-fitting technology, both of which were developed over several years inside the company. Through the modeling of hand shapes, this new technology enables fast recognition of gestures using a small amount of memory. It recognizes hand gestures from a an image as small as 40 pixels from about 10cm to several meters and can be used on smartphones and tablets with a recognition speed of 30fps using a 1GHz Qualcomm SnapDragon processor. The small program size means it can be embedded in a wide range of other devices.

The company says it will further develop its image sensing technology for detecting faces and recognizing human movements, aiming to create technology to correctly interpret the intention of users, such as judging what they are trying to do through the analysis of gestures.
