For making object of the present invention, technical scheme and advantage clearer, clear and definite, referring to accompanying drawing, developing simultaneously, the present invention is described in more detail for embodiment.
Referring to Fig. 1, the touch-screen slip processing module of the electronic equipment with touch-screen provided by the invention comprises: touch-screen, touch-screen driver module, sampling module, average acceleration computing module and sliding mode machine.Described touch-screen connects touch-screen driver module, described sampling module connects described touch-screen driver module, described average acceleration computing module connects described sampling module, described sliding mode machine connects described average acceleration computing module, and described touch-screen driver module also connects described sliding mode machine.
Described sampling module connects described touch-screen driver module, location coordinate information when obtaining user, on touch-screen, slide occurs by described touch-screen driver module, and be provided with clock module in described sampling module, for controlling the cycle of described sampling module sampling, certain interval of time regularly samples the position coordinates of slip.Described sampling operation starts to start receiving touch action when touch-screen.Described average acceleration computing module connects described sampling module, and the location coordinate information obtaining according to sampling module calculates the average acceleration of current slide.And the average acceleration of obtaining is sent in sliding mode machine, in described sliding mode machine, be provided with a judge module, wherein be provided with a plurality of decision gate limit values, specifically comprise rapid door limit value and threshold value rapidly, for judging what state current slide is in.When being less than rapid door limit value, average acceleration is judged to be normal condition; If average acceleration is less than rapidly threshold value and is greater than rapid door limit value and is judged to be fast state; If average acceleration is greater than threshold value rapidly and is judged to be state rapidly.
Described touch-screen driver module connects described sliding mode machine, from institute's sliding mode machine, obtains the state when front slide, if normal condition, described touch-screen driver module drives described screen to roll according to the pixel of normal rolling; If fast state, described touch-screen driver module drives described screen to roll according to 2 times of the pixel of normal rolling; If state rapidly, described touch-screen driver module drives described screen to roll according to 4 times of the pixel of normal rolling.
After user's EO each time, sliding mode machine is automatically converted to normal condition.
This programme adopts the mode of finite state machine (sequential logical circuit module), and user's mode of operation is analyzed and mated, and under different states, adopts different roll screen speed, user-friendly.
In method provided by the invention, by according to the speed of user operation, by user's division of operations, be following several Status Types (but being not limited to this several states): 1. normal condition: under this state, mobile phone is processed user's sliding action according to normal sliding speed.2. fast state: mobile phone slides according to 2 times of gains of normal sliding speed under this state, i.e. 200 pixels of normal condition screen scroll, 400 pixels can slide under fast state.3. state rapidly: mobile phone slides according to 4 times of normal sliding speed under this state.
For touch-screen, its sample period is 10ms, and every 10ms can export one-shot measurement coordinate.The sample period of baseband circuit is adjustable, is generally the multiple of 10ms.User's operating cycle, for the operation of quick sliding, the coordinate points distance slipping between twice sample period was larger between 0.5s to 3S; And for the operation of sliding at a slow speed, the coordinate points slipping between twice sample period distance is shorter.
For user's slide is classified, need a criterion of definition, the present invention is by calculating each average acceleration of sliding as the standard of judgement.And a plurality of threshold values are set, comprise fast state threshold value K and status threshold values Z rapidly.
Method provided by the invention comprises the following steps:
Steps A: user's slide is carried out to periodic sampling, obtain the position coordinates of slip;
Step B: by the position coordinates that repeatedly sampling is obtained, calculate the average acceleration of user's slide;
Step C: according to current average acceleration, judge the residing sliding mode of current slide;
Step D: touch-screen driver module reads sliding mode, and according to the rolling distance of user's sliding distance output screen.
Consider that user points the impact of acceleration, adopt 100ms as the reference duration of algorithm.The sample period of baseband circuit is 20ms, can report and measure coordinate 5 times within the time of 100ms.According to these 5 measurement coordinates, calculate the average acceleration of 100ms in the cycle.By average acceleration, compare with default thresholding, when average acceleration is greater than 0, while being less than K, be judged to be normal slip; Average acceleration is greater than K, while being less than Z, is judged to be quick sliding; When average acceleration is greater than Z, is judged to be rapidly and slides.
Disposal route under the different conditions of the present invention's definition is: during normal condition, screen rolls according to the pixel of normal rolling; During fast state, screen rolls according to 2 times of the pixel of normal rolling; Screen rolls according to 4 times of the pixel of normal rolling during state rapidly.At fast state and the multiple of the pixel that state rolls be rapidly self-defining, be not limited to 2 times and 4 times, also can limit other multiple relations.
Screen driver module reading state machine data, operates according to different states.Take common web page browsing as example, and current reference coordinate point is (0,500), user in Y-axis down sliding 400 pixels, sliding mode is judged to be fast state.Under existing implementation, mobile device should carry out mapping operation for reference coordinate point with (0,900), realizes the rolling of webpage.And in the realization of this programme, screen scroll module will read the state of sliding mode machine, add the gain of sliding.Reading sliding mode is quick sliding, and the pixel that should pass through is 400*2=800, and mobile device carries out mapping operation (being the twice of the pixel of normal roll screen) with (0,1300) for reference coordinate point.
User operates touch-screen, obtains the average acceleration a in user 100ms, is sent into sliding mode machine and adjudicates.The function of processing screen scroll will call this state, when in fast state, according to the gain of 2 times, roll, and when state rapidly, according to the gain of 4 times, roll.
For from fast-descending to situation at a slow speed, the present invention is also provided with a biasing thresholding, and when in sliding mode rapidly, average acceleration is less than Z – s(s for biasing thresholding), be judged to be quick sliding; When in quick sliding state, average acceleration is less than K – s(s for biasing thresholding), be judged to be normal slip.This design is to switch for fear of the frequency that may occur in state boundaries, adds biasing thresholding, and near the frequency that can effectively reduce switching reference point is switched.
The present invention measures by the operation to user in time domain, and the behavior of predictive user, for the quick sliding in short-term, adds the gain of sliding, and for the pinpoint slide of needs at a slow speed, not adding the gain of sliding.User's mode of operation is analyzed and mated, under different states, adopt different roll screen speed, user-friendly.
Should be understood that, application of the present invention is not limited to above-mentioned giving an example, and for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
