Description

  The present invention relates to a position determination apparatus using a fingerprint, and more particularly to an apparatus for controlling a cursor position of a display using a fingerprint identification function.

In application areas where the display is the control interface, known mice are primarily designed to determine the position of the cursor, and even when the known mouse is in wired or wireless signal transmission form, the mouse is flat when used. If it is not placed on an opaque plate surface, normal cursor position determining ability cannot be exhibited.

Furthermore, in order to increase the effect of using safety control, there is an increasing demand for technology that uses fingerprint identification as a safety identification device, taking advantage of the fact that human fingerprints cannot be counterfeited. However, it is just the ability to identify fingerprints.

  The main object of the present invention is to provide a position determination apparatus using a fingerprint and to solve the above-mentioned problems.

  The device for determining the control position by fingerprint according to the present invention is used for combining various products with a display as an interface control. At least, a housing having an image capture window whose surface is a fingerprint sensing area, and mounted on the image capture window It is composed of a fingerprint sensor that acquires a continuous image when the user's fingerprint moves in the sensing area with low resolution by controlling the electronic circuit, and uses it for position determination, thereby controlling the cursor movement by the fingerprint Achieve the ability to do.

The device for determining the fingerprint control position of the present invention is
(1) Since the present invention controls the relative movement of the cursor by changing the movement of the fingerprint, it is not limited to operations on a flat plate surface and is convenient to use.
(2) Since the present invention is not limited to use on a flat plate, the housing has a molding change space, and the appearance molding is flexible.
(3) The production cost is low, and safety control can be used.

  FIGS. 1 and 2 are views showing a first embodiment of an apparatus for determining a position using a fingerprint according to the present invention. The present invention is used for a host computer system 50 application of various products having a display 40 as an interface control, and a display cursor. Achieve the primary objectives and merits of 41 positioning. This structure has a housing 10 having an image capturing window 11 serving as a fingerprint sensing area 12 of a user's finger 1 at an appropriate location on the surface, and a fingerprint of the sensing area 12 mounted on the image capturing window 11. And a fingerprint sensor 20 for acquiring an image.

  The main technical feature of the present invention is that when the user leaves the fingerprint part of the finger 1 in the sensing area 12 of the housing, the electronic circuit 30 is activated to cause the fingerprint sensor 20 to move at a low resolution during the movement of the fingerprint in the sensing area 12. Capturing a large number of continuous images, analyzing the relationship of changes in the continuous images, obtaining the amount and direction of fingerprint shift, and achieving the ability to control the relative movement of the cursor of the display 40 by the host computer system 50.

  Referring to FIGS. 2 and 3, another technical feature of the present invention is that when the fingerprint portion of the user's finger 1 is left in the sensing area 12 of the housing, the same fingerprint sensor 20 is activated by the operation of the electronic circuit 30. Captures a stationary fingerprint image of the sensing area 12 with high resolution and transmits it to the host computer system 50 of the display 40 that applies the fingerprint image to perform fingerprint identification operations such as storage, analysis, comparison, etc. Achieve safety management use that combines identification.

  The fingerprint sensor 20 is an optical (CCD or CMOS) sensor 21 and is a general inductor-sensitive sensor 22 in FIG.

  Referring to FIG. 5, the housing 10 of the present invention is provided with a lid 13 at a position corresponding to the sensing area 12 to prevent the sensitive surface of the fingerprint sensor 20 from becoming dirty, and the fingerprint sensor 20 is optical (CCD Or the CMOS) sensor 21, the lid 13 is made of a transparent material and can capture a fingerprint image of the sensing area 12. When the fingerprint sensor 20 is the inductor sensitive sensor 22, the lid 13 is made of a transparent or non-transparent material. Further, the lid 13 may be a fixed type, a movable type lid as shown in FIG. 6, or a sliding type.

  In the present embodiment, as shown in FIGS. 7 and 8, the actual operation mode of the lid body 10 is a portable configuration convenient for use in the hand and a fixed configuration that can be used for localization. Further, the housing 10 is a housing used by the host computer system 50 of the display 40 that is desired to be used in combination.

  As described above, the fingerprint positioning control device of the present invention is not only capable of combining various products with a display interface control, but also allows the user to operate the position of the display cursor in the air, thus ensuring fingerprint identification safety. Achieving a multi-function implementation effect that provides control use.

  In the present invention, preferred embodiments have been disclosed as described above. However, these are not intended to limit the present invention, and any person who is familiar with the technology can use various methods within the spirit and scope of the present invention. Therefore, the protection scope of the invention is based on the contents specified in the claims of the utility model.
