Abstract: A radio device, which is the source, transmits a route request packet (RREQ) to a radio device. In response to the route request packet (RREQ), the radio device transmits to the radio device a route setup packet (RSET) including a route Radio Device Radio Device Radio Device Radio Device by looking-up topology information (TPIF). In response to the route setup packet (RSET), the radio device produces a route notification packet (RNTF) and transmits the produced route notification packet (RNTF) to radio devices, and. In response to the route notification packet (RNTF), the radio device, which is the destination, produces a route reply packet (RREP) and transmits the produced route reply packet (RREP) to the radio device, which is the source.

Abstract: A system for reproducing audio information corresponding to a position within a displayed image comprising an image display device (1) which shows an image, an audio output device (2) which outputs an electromagnetic wave modulated by audio information toward any given positions in the image shown on the image display device (1), and an audio reproducing terminal (3) which receives the electromagnetic wave at the position in the image, converts it to an electric signal and reproduces sound from that electric signal, wherein audio information support can be individually realized for each of the users watching the image.

Abstract: A source terminal measures characteristics of the path at the source terminal itself, produces a characteristics-measurement packet, and transmits the produced characteristics-measurement packet to a relay terminal. Upon receiving the characteristics-measurement packet, the relay terminal measures characteristics of the path at the relay terminal itself, renews the characteristics of the path included in the characteristics-measurement packet using the measured characteristics of the path, and transmits the characteristics of the wireless communication path to the destination terminal. The source terminal produces an admission-request packet and transmits the packet to the destination terminal. Upon receiving the admission-request packet, the destination terminal allows or rejects the traffic quality maintenance request according to the characteristics of the wireless communication path.

Abstract: An object of the present invention is to provide a device and a method for recognizing hand shape and position even if a hand image to be provided for recognition is rather complicated in shape, and a recording medium having a program for carrying out the method recorded thereon. A hand image normalization part 11 deletes a wrist region respectively from a plurality of images varied in hand shape and position before subjecting the images to normalization in hand orientation and size to generate hand shape images. An eigenspace calculation part 13 calculates an eigenvalue and an eigenvector respectively from the hand shape images under an analysis based on an eigenspace method. An eigenspace projection part 15 calculates eigenspace projection coordinates by projecting the hand shape images onto an eigenspace having the eigenvectors as a basis.

Abstract: An object of the present invention is to provide a method of segmenting hand gestures which automatically segments hand gestures to be detected into words or apprehensible units structured by a plurality of words when recognizing the hand gestures without the user's presentation where to segment. Transition feature data in which a feature of a transition gesture being not observed during a gesture representing a word but is described when transiting from a gesture to another is previously stored. Thereafter, a motion of image corresponding to the part of body in which the transition gesture is observed is detected (step S106), the detected motion of image is compared with the transition feature data (step S107), and a time position where the transition gesture is observed is determined so as to segment the hand gestures (step S108).

Abstract: A hand gesture recognizing device is provided which can correctly recognize hand gestures at high speed without requiring users to be equipped with tools. A gesture of a user is stereoscopically filmed by a photographing device 1 and then stored in an image storage device 2. A feature image extracting device 3 transforms colors of the stereoscopic image data read from the image storage device 2 in accordance with color transformation tables created by a color transformation table creating device 13, and disassembles and outputs the feature image of the user in corresponding channels. A spatial position calculating device 4 calculates spatial positions of feature parts of the user by utilizing parallax of the feature image outputted from the feature image extracting device 4. A region dividing device 5 defines the space around the user with spatial region codes. A hand gesture detecting device 6 detects how the hands of the user move in relation to the spatial region codes.
