TW472206B - Seeing eye mouse for a computer system - Google Patents

Abstract

An optical mouse (1, 15) images as an array of pixel (10) the spatial features of generally any micro textured or micro detailed work surface (5) below the mouse. The photo detector (10) responses are digitized stored as a frame into memory. Motion produces successive frames of translated patterns of information which are compared by autocorrelation to ascertain the direction and amount of movement. A hold feature (37) suspends the production of movement signals to the computer, allowing the mouse to be physically relocated on the work surface without disturbing the position on the screen of the pointer. This maybe needed if the operator runs out of room to physically move the mouse further, but the screen pointer still needs to go further. The holder feature may be implemented with an actual button (24), a separate proximity detector (27/28) or by detecting the presence of a characteristic condition in the digitized data, such as loss of correlation or velocity in excess of a selected limit. A convenient place for an actual hold button is along the sides of the mouse near the bottom, where the thumb and the opposing ring finger grip the mouse. The gripping force used to lift the mouse engages the hold function. Hold may incorporate a grief delay (42) upon either the release of the hold button, detection of proper proximity of the return of reasonable digitized values. During that delay any illumination control of AGC servo loops stabilize. A new reference frame (31) is taken prior to the resumption of motion detection.

472206 A8 B8 C8 VI, please paste the circuit (12), the mobile 电路 j circuit produces a lighted circuit in the direction along these first and second cars, relative to what can be seen through the hole Some movement indication signals for the movement of imageable features; and-proximity detectors (24, 34/27, 28), which are coupled to the optical motion detection circuit to detect when the bottom surface is greater than the distance from the work surface -The selected distance, and the movement indication signal is prohibited from being generated when the bottom surface is farther than the selected distance from the surface of the satellite; Disk. Photodetector (10) Some digital photodetectors output one of the test frames (3 1) and 1 reference frame. This number is paid to the output value of this disk. One is a memory frame of the photo frame (32), and the reference frame of the two new reference frames and the control frame of J's legacy are used to indicate the program of the breast number (3 5, 3). 8) Pick up after finishing the match and before replying to the movement instruction signal. 5. The device according to item 4 of the patent application, wherein the proximity detector includes at least one switch (24 on the skirt) located at one of the right thumb or left ring finger of the hand holding the indicator device (24 ). 6. The device according to item 4 of the scope of patent application, wherein the proximity detector includes at least one switch (24) arranged on the skirt at a position below the left thumb or right ring finger of the hand holding the indicator device. . 7. The device according to item 4 of the application #, wherein the optical motion detection circuit includes a plurality of photodetectors (10) each having an output, and a memory containing the output values of some digital photodetectors And the proximity detector contains the arithmetical comparison between the digital detector and the digitized values in the memory.

Road for applying for patents. (Please read the precautions on the back before filling this page) 8. If the device in the scope of patent application is item 4, the proximity detector includes a pressure trigger switch (27, 28) located near the bottom surface. 9. If the device is under the scope of applying for a patent, the new reference frame is' for a period of time after the delay (42) beyond the proximity detector to no longer detect the bottom surface leaving the working surface with the selected distance Obtained after selecting the amount. 10 · —A computer system or similar system with a hand-held indicator device (丨, 14, 15), comprising: a housing having a flat bottom surface (6) on a working surface having one of the imageable features (5) upward movement; the shell also has a top surface (21) shaped to receive a human hand; the shell also has a skirt (20) connecting the periphery of the flat bottom and the top surface; the shell has a substantially smooth A first axis extending from a position where the heel of the hand is placed on the top surface to a position where the middle finger is placed on the top surface, and a second axis perpendicular to the first axis, both axes are parallel to the Bottom surface; a hole (13, 16) located on the bottom surface; a lighting source (2, 3) installed inside the housing close to the hole to illuminate an imageable feature on the working surface; An optical motion detection circuit (12) inside the housing and close to the hole, the motion detection circuit generates a light image representing the direction along the first and second axes and relative to the visible through the hole Liang Zhiben's paper standards are applicable to Chinese national standards (C NS) A4 specification (210X297 mm) " " -30- 472206 A8 B8 C8 D8 Patent application scope Some movement indication signals for the movement of imageable features; and (Please read the precautions on the back before filling this page) 1 A detector coupled to the motion detection circuit detects when the movement of the index device exceeds a selected limit (52) within a time interval, and bans the generation of the movement indication signals in response. 11. The device according to item 1 of the patent application range, wherein the optical motion detection circuit includes a plurality of light detectors each having an output (0), and a reference frame containing the output values of some digital photodetectors (31) Compare one of the digital photodetector output values obtained after the reference frame with a memory of frame (32), and one of the new reference frame and the subsequent control frame is Obtained after the detector no longer detects that the movement of the pointer exceeds the selected limit and before a response is generated to a movement instruction signal.
