In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the side structure schematic diagram of a kind of preferred embodiment of gesture induction module of the present invention.
Fig. 2 is that the partial structurtes of a kind of preferred embodiment of keyboard of the present invention connect block diagram.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the present embodiment provides a kind of gesture induction module 1, described gesture induction module 1 comprises control circuit board 11 and light signal receiving tube 12, the first optical signal launch pipe 13 be located at respectively on described control circuit board 11 and the second optical signal launch pipe 14, and described light signal receiving tube 12 is located between described first optical signal launch pipe 13 and described second optical signal launch pipe 14.
Particularly, described gesture induction module 1 also comprises output interface (not shown), and described output interface and described control circuit board 11 are electrically connected.Described output interface can be SPI (Serial PeripheralInterface, Serial Peripheral Interface (SPI)) interface, also can be IIC (Inter-Integrated Circuit, IC bus) interface.Described control circuit board 11 is MCU Single-chip Controlling wiring board.Described gesture induction module 1 carries out independent control to module separately by described control circuit board 11, by mainboard (the MCU singlechip control panel as the keyboard) control linkage of described SPI interface, IIC interface or other self-defined host-host protocol interfaces and access; Also can directly by access mainboard (the MCU singlechip control panel as keyboard) to as described in gesture induction module 1 carry out direct signal process.Preferably, described first optical signal launch pipe 13 and described second optical signal launch pipe 14 are infrared light emission pipe, and described light signal receiving tube 12 is infrared acceptor.
During work, as shown in Figure 1, when user's hand moves from left to right, because light wave reflection principle, described light signal receiving tube 12 first can receive the data of described first optical signal launch pipe 13, then receives the data of described second optical signal launch pipe 14.In like manner, when user's hand is from right toward when moving left, described light signal receiving tube 12 first can receive the data of described second optical signal launch pipe 14, then receives the data of described first optical signal launch pipe 13.When user's hand rests on the top of described gesture induction module 1 from left to right, by coding and the sequential control of described control circuit board 11, described light signal receiving tube 11 first can receive the signal of described first optical signal launch pipe 13, and then continuous reception is to the signal of described first optical signal launch pipe 13 with described second optical signal launch pipe 14.In like manner, when user's hand turns left the top resting on described gesture induction module 1 from the right side, described light signal receiving tube 11 first can receive the signal of described second optical signal launch pipe 14, and then continuous reception is to the signal of described second optical signal launch pipe 14 with described first optical signal launch pipe 13.Visible, described gesture induction module 1 can respond to four kinds of gesture changes, when keyboard is applied, just can realize four kinds of gesture controlling functions of keyboard.
Same principle, in order to obtain more gesture state, more button using function can be converted to gesture when making to apply on keyboard to control, described gesture induction module 1 also can comprise that to be located on described control circuit board 11 some to the 3rd optical signal launch pipe (not shown), and often pair of described second optical signal launch pipe is respectively with light signal receiving tube 12 described in the corresponding sandwiched of different relative angle.Preferably, described 3rd optical signal launch pipe is similarly infrared light emission pipe.
As shown in Figure 2, the present embodiment also provides a kind of keyboard 100, and described keyboard 100 is built-in with MCU singlechip control panel 2 and described gesture induction module 1, described MCU singlechip control panel 2 and described gesture induction module 1 control linkage.
Because described gesture induction module 1 can respond to four kinds of gesture changes, thus four kinds of gestures changes that described MCU singlechip control panel 2 senses by described gesture induction module 1 obtain four kinds of different Received signal strength and realize four kinds of functions to control described keyboard 100, such as, gesture from left to right, can the backlight of supervisory keyboard move from left to right; The gesture of turning left from the right side, can the backlight of supervisory keyboard from right toward moving left; Rest on the gesture in described gesture induction module 1 from left to right, the volume that can control computer increases gradually; Turn left from the right side gesture be parked in described gesture induction module 1, the volume that can control computer reduces gradually.In like manner also can control other buttons or MultiMedia Keyboard function by the change of above four kinds of gestures.
The gesture induction module that the present embodiment provides, it is only made up of control circuit board, light signal receiving tube, the first optical signal launch pipe and the second optical signal launch pipe, and structure is very simple, and compared with existing optical image module induction module, cost is lower.Meanwhile, because this gesture induction module utilizes optical sensor principle to carry out gesture control, so larger to the distance range of user's hand and intermodule, can not maloperation be produced, make it manipulation and get up convenient.And the keyboard that the present embodiment provides, owing to have employed this gesture induction module, a part for the button use-pattern of this keyboard is made to change gesture control mode into, light and the button control mode of conventional keyboard are enriched, special for gamepad, change the body sense of traditional game player, enhance the participation of game player.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
