Embodiment
For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The invention provides a kind of two key gesture identification methods based on condenser type single-point touches button, the position difference that two of foundations and plural condenser type single-point touches button are put on an effective physical surface of reality, realize the gesture motion of the various orientation angles of up and down or left and right etc., it is combined by 3 specific logical algorithm modules, be respectively key-press status Processing Algorithm module, wait for time slot algorithm module and feature operation algoritic module, wherein:
Key-press status Processing Algorithm module mainly comprises that denoising Processing, misoperation elimination, state control submodule form.This module completes the effective action of button, and the operate condition validity of this button is controlled.
Wait for that time slot algorithm module mainly comprises timer, counter, Status Flag control submodule.Wait for that time slot algorithm module has two logic states, one is definition status, and one is timeout mode.This module is mainly processed the control of mobile direction and velocity information and timing and timeout mode mark.
Feature operation algoritic module comprises key-press status buffering area, data comparator, logical process and fuction output submodule.Process the data of key-press status buffering area, the Status Flag of output corresponding function action.
Taking the gesture operation being moved toward touch key-press B from touch key-press A as operating personnel as shown in Figure 1 as example, further illustrate the present invention below, in conjunction with Fig. 2 and Fig. 3, the steps include:
Step 1, key-press status processing:
After touch key-press A is pressed, judge that by key-press status Processing Algorithm module whether it is effective, if effectively, export a logic state position and trigger the startup of waiting for time slot algorithm module, the state that simultaneously continues judge touch key-press A whether sustained touch or release is upspring, and forbidden energy locks the button passage of touch key-press B simultaneously, enters step 2, if invalid, continue initial holding state.
Step 2, timing are with overtime:
After startup, start the timing to touch key-press A by it, timing is divided into multiple time slots, and time slot is counted until touch key-press A is effectively discharged, when the number of time slot reaches after predefined threshold value, overtime mark is sent into A district, buffering area, otherwise, the number of time slot is sent into A district, buffering area, simultaneously the button passage of enable open touch key-press B, wait for that touch key-press B is pressed, and reset for the second time and start and wait for time slot algorithm module and key-press status Processing Algorithm module.
Starting for the second time in the process of waiting for time slot algorithm module, if timeout mode is effective, skips and judge whether touch key-press B presses, output overtime Status Flag is to B district, buffering area; If have touch key-press B to send into B district, buffering area by the next number by the time slot of waiting for for the second time time slot algorithm module in definition status.No matter have or not button to press, all will finish thereafter and forbidden energy wait time slot algorithm module and key-press status Processing Algorithm module, finally trigger start-up performance operative algorithm module, enter step 3.
Step 3, feature operation algoritic module:
Feature operation algoritic module after starting is processed the data in the data in A district, buffering area and B district, buffering area.After completing processing, empty buffering area.Restart key-press status Processing Algorithm module and wait for time slot algorithm module.
When the timeout mode in A district, buffering area is effective, do not process B district, buffering area, directly output function value correspond to long by.
The timeout mode in A district, buffering area is invalid, judges the number of time slots in B district, buffering area.If the countless certificates in B district, buffering area, the output function value corresponding with the number of time slots in A district, buffering area.
In the time that there are data in B district, buffering area, if the timeout mode in this district is effectively, be abnormality, directly finish the processing of this feature operation algoritic module.The invalid number of time slots of calculating B district, buffering area of timeout mode, number of time slots has determined the gesture translational speed of touch key-press A to touch key-press B, and number is fewer, and speed is faster.According to the number of time slots in B district, buffering area, export corresponding function value.
Said method can also be applied in multiple buttons as shown in Figure 4, as between touch key-press A and touch key-press B in Fig. 4, between touch key-press A and touch key-press C, between touch key-press A and touch key-press D, between touch key-press B and touch key-press C, between touch key-press B and touch key-press D and all can adopt said method between touch key-press C and touch key-press D.
