In order to achieve the above object, the present invention is by the following technical solutions:
A kind of gesture identifying device based on light conduction, comprise printing opacity identification plate (1), panel identification point (2) and identification box (3), it is characterized in that: the upper surface of described identification box (3) is provided with printing opacity identification plate (1), printing opacity identification plate (1) is provided with n1 × n2 panel identification point (2), wherein n1 × n2 is natural number, n1 × n2 root matrix arrangement fibre bundle (8) is provided with in printing opacity identification plate (1) bottom, one end of described matrix arrangement fibre bundle (8) is connected with base plate identification point (9), the other end successively with LCD liquid crystal display (7), light guide plate (6), LED light source (5) is connected with disposal system (4), described LCD liquid crystal display (7), light guide plate (6), LED light source (5), disposal system (4), matrix arrangement fibre bundle (8) and base plate identification point (9) are positioned at and identify that box (3) is inner.
Further, it is luminous that described disposal system (4) controls LED light source (5) interval, and coordinate with light guide plate (6), LCD liquid crystal display (7), send light signal by strategy respectively to each bar optical fiber, identify gesture by intensity of reflected light.
Further, wherein disposal system (4) includes power module, wifi receiver module and embedded system.
Further, described embedded system is andorid, ios or Windows Phone.
Further, containing receiver in described LED light source (5), the light that LED light source (5) sends is visible ray, infrared light or ultraviolet light.
Further, described LCD liquid crystal display (7) is transmission-type.
The invention has the advantages that use fiber optic conduction, make signal by the interference of electromagnetism, transmission is stable, have reliable operation, stable, respond the advantages such as fast; Reflecting LED light source with minimum light loss by light-output, and can have the advantages such as light efficiency is high, brightness is large, the life-span is long, energy-conserving and environment-protective; The use of light guide plate not only have guide-lighting evenly, energy-saving and environmental protection, the not easily advantage such as aging, and the line source coming from optical signal generator can be changed into area source, thus original n1 × n2 line source is reduced to 1, this greatly reduces use cost; Use transmission type LCD liquid crystal display, can ensure when dim, make user see the screen of brightness uniformity.
