Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is elaborated, should be appreciated that following illustrated preferred embodiment is only for description and interpretation the utility model, and be not used in restriction the utility model.
Fig. 1 is the structural representation of the touching device hardware of the notebook computer that provides of the utility model embodiment, and as shown in Figure 1, according to common notebook computer user's use habit, the wrist restitope that during typewriting, the left hand right hand can be placed on touch pad both sides is put.Concrete steps are as follows:
Step 1: by range sensor or capacitive sensor array (two range sensor or capacitance type sensor) are placed on to the position that wrist is depended on nearly keyboard, make user's both hands when typewriting can be placed on two range sensors or capacitive sensor array directly over.
Step 2: when range sensor or capacitive sensor array sense that user is placed on hand wrist restitope and puts, represent that user is in typewriting state, range sensor or capacitive sensor array send to notebook computer embedded controller by low level triggering state; When range sensor or capacitive sensor array sense that user leaves hand wrist restitope and puts, represent that user exits typewriting state, range sensor or capacitive sensor array exit low level and trigger state.
Step 3: the low level that notebook computer embedded controller receives from range sensor or capacitive sensor array triggers state, utilize software in embedded controller to resolving from the level state of range sensor or capacitive sensor array, determine whether embedded controller opens touch pad enable signal.
Step 4: what obtain if resolve is to close touchpad command, and user is in input state, and embedded controller is closed function of touchpad by closing touch pad enable signal; What if resolve, obtain is to open touchpad command, and user exits input state, and embedded controller is opened function of touchpad by opening touch pad enable signal.In addition, embedded controller can also utilize electric switch to close or open function of touchpad.
Fig. 2 is the embedded controller structural drawing of the touching device hardware of the notebook computer that provides of the utility model embodiment, Fig. 3 is range sensor/capacitive sensor array structural drawing of the touching device hardware of the notebook computer that provides of the utility model embodiment, Fig. 4 is the touch pad connector construction figure of the touching device hardware of the notebook computer that provides of the utility model embodiment, as Fig. 2, 3, shown in 4, annexation performance is: the clock pin of range sensor or capacitive sensor array and data signal pin are connected with pin 95 with the pin 94 of the System Management Bus (SM BUS:System Management BUS) of embedded controller respectively, the signal output part of range sensor or capacitive sensor array connects respectively pin 82 and the pin 83 of the universal input/output (GPIO:General Purpose Input Output) of embedded controller.The pin 89 of the PS2 interface of embedded controller is connected with touch pad with pin 90, via pin 89 and pin 90, will utilize the touch pad enable signal of Software Create to send to touch pad connector, wherein, according to the difference of touch pad model, can also, according to the model of touch pad, the SM BUS of embedded controller be connected with touch pad via touch pad connector.
Idiographic flow shows as: range sensor or capacitive sensor array, by detecting user's use state, send to embedded controller using the high/low level analogue signals as embedded controller input.Embedded controller carries out analog to digital conversion to described simulating signal, and the digital signal being converted to is resolved, and is closed/open touchpad command.Embedded controller according to obtain close/open touchpad command control touch pad close or open function of touchpad.Wherein, range sensor array is the range sensor the array whether wrist of utilizing light pulse to detect user is depended on the position of nearly keyboard distance to wrist reaches preset threshold value.Capacitive sensor array is whether in wrist, to depend on the capacitance sensor array of the position of nearly keyboard according to the electric field change induction user's of electrode wrist.
Fig. 5 is the method schematic diagram of the touching device hardware of the notebook computer that provides of the utility model embodiment, as shown in Figure 5, using range sensor or capacitance type sensor as embedded controller, the low level signal of input is as triggering state, , range sensor or capacitance type sensor are low level as the signal of embedded controller input, range sensor or capacitance type sensor are in triggering state, range sensor or capacitance type sensor are high level as the signal of embedded controller input, range sensor or capacitance type sensor be not in triggering state.If range sensor or capacitive sensor array exist the state that do not trigger, determine that user exits input state, and control touch pad and open function of touchpad.Only have range sensor or capacitive sensor array all when triggering state, just definite user is in input state, and controls touch pad and close function of touchpad.
In sum, the utlity model has following technique effect: can whether be in input state by increase range sensor or capacitive sensor array detecting notebook computer user, realize and automatically close or open function of touchpad.Thereby reduce notebook computer user puzzlement in use, the user who improves notebook computer experiences, what allow notebook computer touchpad can intelligence provides service for user.
Although above the utility model is had been described in detail, the utility model is not limited to this, and those skilled in the art of the present technique can carry out various modifications according to principle of the present utility model.Therefore, all modifications of doing according to the utility model principle, all should be understood to fall into protection domain of the present utility model.
