China,Japan : Fujitsu Develops 3D Gesture Recognition Technology Capable of Complex Tasks with a Single PC or Tablet Camera [TendersInfo (India)](TendersInfo (India) Via Acquire Media NewsEdge) Fujitsu Laboratories Limited and Fujitsu Research and Development Center Co., Ltd. of China today announced the development of 3D hand gesture recognition technology that, using video captured on a single PC or tablet camera, can detect not only vertical and horizontal hand motion, but also the forward and backward movements of increasing or decreasing distance of a hand from the display. With existing hand gesture recognition technology it has been possible to detect hand motions along the vertical and horizontal axes, which represent operations similar to moving a mouse cursor. However, detecting forward and backward hand motions changing distance to perform the same function as a mouse click has proven difficult. Fujitsu Laboratories and Fujitsu R&D Center have developed technology for accurately and quickly detecting the area of a hand based on models of palms, as well as a technology that detects forward and backward hand motions. This has made it possible for users to perform click operations through intuitive "push" gestures. The new technology makes it possible to use hand gestures to perform a host of complex operations. For instance, a user can wave his or her hand up and down to make a menu selection on a PC and then confirm the selection with a "push" gesture, even from a distance. Maps and other images can also be expanded or shrunk with "push" and "pull" gestures. Details of the new technology will be announced at the International Conference on Machine Vision Applications (MVA) 2013, to be held starting May 20 at Ritsumeikan University in Kyoto, Japan. In recent years, attention has been gathering around hand gesture recognition technologies, which enable devices to be controlled through natural human movements. This approach to operating a device through hand motions that are detected with a camera is typically employed in situations when a user is physically separated from a PC or tablet device, when the user's hands are wet or dirty, or when the user does not want to directly touch a publically accessible device due to hygiene concerns. When attempting to substitute hand gestures for mouse operations, it has been possible to detect vertical and horizontal hand motions that are similar to how a mouse cursor moves, but detecting depth, as in forward and backward hand motions, which are equivalent to mouse clicks, has been difficult. Detecting forward and backward hand motions with a single camera relies on changes in the area of the user's palm. When the user is wearing short-sleeved clothing, however, or when the background is a color similar to the user's skin tone, it is difficult to distinguish between the user's palm and the background. As a result, it has been impossible to accurately extract the area of the user's hand from the background. (c) 2013 Euclid Infotech Pvt. Ltd. Provided by Syndigate.info an Albawaba.com company |
