| 摘要 |
The invention relates to an opto-electrical device with fiducial marks meant for man-machine interfacing in multi-user multi-point touch systems carried out with optical methods and which have characteristics and behaviours similar to the real objects generally found on the frontal panel of an apparatus, such as press buttons, displays, control elements. According to the invention, the device comprises a mechanical support (1) adapted to the size of a human hand, which comprises a matrix (2) of visible or infrared punctiform sources, supplied from a mobile voltage source (3), a guiding grid (4) which together with the matrix (2) allows the manufacture of optical marks, a series of slots (5) for detecting the incident light radiation, a photoelectric transducer assembly (6) which detects the light radiation and controls the selective switching on of the sources forming a fiducial mark, a pressure sensor (7) which permits the decrease of the energy consumption and the detection of the interaction between the user and the device, a switch (8) for starting the device and a plate (9) for diminishing parasite reflections. |
