The generating device 2 generates a plurality of grating beams 2, 1, 202, 203, 204, etc., which are used in the upper and lower six rows of the virtual keyboard image light layer 11 (please match the third and seventh figures). The ingesting device 3 forms the light beam 3〇 in a grid-like intersection with the grating beam 2〇, and forms the bottommost contour surface ρι at a position lower than the cross-sectional height of the finger 5 of the finger 5, which is an operation finger. 5 enters the human analog keystroke. If the position of the third grating beam 2 () 3 is applied, the light pattern of the 7th surface P1 is related to the finger 5, and the light beam 2ΰ3 will form a light and shadow change on the surface of the finger 5. After the ingestion device 3 takes the change, it is judged that the button of the suspect is touched by the image processing device 3, and the input command is provided to provide the information machine as the execution command basis. The design of the present invention sets the first contour surface ρι at the height of the cross-section of the fingertip 51 of the finger 5, and the body of the hand and the body of the finger 5 are smaller, the root is thicker, and the operation button White enters the button position by the tip 51, and the pressing operation of the finger pad 52 is similar to the habit. Then, in the second space of the fingertip 51, the area of any button is in the vertical space, which is in the first contour plane? ! The horizontal position == is set by the fingertip into the person's knives, and is set as the reference of the axis, so that the height of the P1 is lower than the fingertip, and the light is changed by the _ into the person, mentioning: 1: ^ It is necessary to refer to the f53 riding system is higher than the first - contour surface ρι, _ will be 4 P2, Ρ 3 "· do 'but the surface of the reading / foreign body into the role of the key to judge the basis, more above = input The operator pauses typing into the horror of the fun. #作峨' Provides a snatch to enter the heart test, when the palm is raised slightly, there will be no misuse of 200836086, or a foreign object such as paper or pen will pass over the upper level. P2, P3, ... are not judged as a keystroke operation. The ingestion device 3 is an electronic imaging device formed by an electronic photosensitive device of CCD or CMOS, and the corresponding button 110 (please match the figure 7) is arranged to the left and right. First, the matrix orientation is set, such as the spacing between the buttons 110A and 110B. When 110A is operated, Η〇β determines no action. The previous setting can be set by the video signal processing device. The virtual keyboard image layer 11 is When the finger enters the virtual button 11Q, the worker is In principle, an operation command occurs, and the invisible grating beam 20 is based on the position of the button arranged in the latitudinal direction, and the first beam 2 (投射, the second grating beam 2G2, the third grating beam 2G3, and the fourth grid are projected). The shape of the light beam 204···, and the matrix position of each virtual button 110 is such that after the ingestion device 3 is ingested, the image processing device 300 pre-plans the left and right spacing, and the relative left and right spacing of the keys can be previously prepared in a predetermined manner. Position, if the finger 5 enters the user to operate it - the button (10), and is located in the linear position of the fourth grating beam 2 () 4, the position of the function where the button is cut, and the change of the shadow pattern is generated. Providing the foregoing image processing device to obtain a change judgment basis, and achieving each trigger operation of each key input. The arrangement of the present invention, the step-by-step can be adopted, and the visible light is invisible and visible. 'As shown in Figure 9, 'Infrared light source 6 is used, single-beam suppression occurs, 61 B1 'B2 5 ^ B1 is changed to form a spectral range such as green light, and then emitted by phase arrangement Out of 10, after the projection A visible image of the keyboard image light layer n; the nine-dimensional beam B2 is directed by the reflective element 63 to the invisible grid beam 20 required by the modulation device, and if the basic conditions are to be "laughing eight ^", such as shooting, then PW (four) mu Scanning the image layer of the image is the ingesting device 3, and the image judgment is achieved. If the cost is the same, and the laser diode is used as the laser element, the power consumption is low. Please refer to Figure 10 for the 'source' saving component. As shown in the present invention, the image of the image 200836086 is generated by a projection device 1 to form a keyboard image layer u, and the two opposite modulated light generating devices 2a, grating beams 2GGA, 2_' and the light in the keyboard image Three layers above layer u | Interference interference occurs to multi-layer contour faces P1, Ρ 2, Ρ 3..., - Ingestion device 3 monitoring: hand (four)... cans, and fine _ _ _ _ _ _ _ 5 When entering the keyboard image 100 and simulating the keystroke action, the first contour plane P1 of the lowest layer of the fingertip changes the shadow of the first contour plane pi, and the change = the changed light beam 30 is formed by the intersection device 3 ingested, and transposed by the image, 2 vertical or horizontal signals Shadow patterns change as the key is moved above the determination, the touch signal at a fixed information referred to as a command processor basis. The above-mentioned modulation level devices 2A, 2B and the projection device 四 (4) are prefabricated, and the pre-implementation of the same 'the subject is __scale device 2A, 2_ray interlaced, 2_, face, and above the key»image (10) The three-dimensional three-dimensional space (10) transaction interferes to obtain a multi-layered contour surface, at least the lowest level of the first-equal surface ρι is the finger-touching light-grain change = the fundamental basis, (4) the second-high surface P2 or more is affected by foreign objects. The change in formation does not input the judgment of the action, so the explicit keystroke action can be captured. μ Referring again to Fig. 11, in order to accommodate the operator's arm spanning habit, the continued keyboard optical layer U' of the present invention can be projected to have a v-shaped opening angle Θ. The squatting surface forms the "U" keyboard image of the left keyboard Ua and the keyboard lib, and the aforementioned invisible scanning grating beam, and the ingesting device and the image processing device, etc. The projection degree is basically to divide the grating beam into two passes, 2 GB, and the angle of the opening is symmetrical.
