Embodiment
The present invention marks off a plurality of regions on Trackpad, and set different threshold values in different regions, easily causing the less threshold value of region use of false touch, surpass this threshold value and be considered as false touch, to reach the function of strengthening false-touch prevention, and user can adjust position or the size in each region on Trackpad voluntarily according to different mechanism design or use habit, to reduce the generation of false touch.
Fig. 2 is the schematic diagram of the embodiment of the present invention.The present embodiment is divided into tworegions 20,22 byTrackpad 18, andfirst area 20 is set with the first threshold value, and the second threshold value that 22 settings of second area are less than the first threshold value, in order to strengthen the function of false-touch prevention.User can adjust position or the size ofsecond area 22 according to the difference of mechanism design and the difference of use habit, improves the probability of false touch.And be on zoning, canfirst area 20 andsecond area 22 simply be divided out through adjustment coboundary wide (Up Wide), lower boundary wide (Down Wide), left margin wide (Left Wide), four numerical value of right margin wide (Right Wide).
Fig. 3, Fig. 4 are the enforcement schematic diagram that the present invention is applied to notebook computer.Difference according to the mechanism design of notebook computer, can adjust position or the size ofsecond area 22 on Trackpad 18, as Fig. 3,Trackpad 18 designs the place, central authorities below inkeyboard 12, upper limb, left border and the right border of easy accident touch ontouch control plate 18 while usingkeyboard 12 according toleft hand 14, theright hand 16, therefore define onTrackpad 18, left and right borderline region issecond area 22, and uses the second less threshold value, improves the probability of false touch.And when the mechanism designing is different, as Fig. 4, Trackpad 18 may be designed to lower left or the lower right ofkeyboard 12, and now the upper limb of easy accident touch ontouch control plate 18, is therefore thatsecond area 22 just can reach the incidence of improving false touch as long as defineTrackpad 18 regions, coboundary.
Fig. 5 is the enforcement schematic diagram that the present invention is applied to touch controlled handset 24.Because of the difference of user'spalm 26 sizes, also there is the problem of false touch in touch controlled handset 24.Because false touch is easily caused in the left and right of pointing in Trackpad 28, therefore define the middle 30Wei first area, region of Trackpad 28, left and rightborderline region 32,34 is second area, uses less threshold value, prevents the generation of false touch.In other embodiment, because the difference of user's operating habit, define respectively the left and right borderline region of Trackpad 28 32,34 for second and third region, and according to user's strong hand, come size and the threshold value thereof of settingregions 32,34, in order to improve the probability of false touch.
Fig. 6 is the process flow diagram of Application Example of the present invention.The Application Example of Trackpad of the present invention, there are two kinds of patterns, for energy normal running when operating Trackpad, when Trackpad is during as main operation interface, just switch to first mode, full contact panel is only used a larger threshold value, other time be the second pattern, on Trackpad, mark off a plurality of regions, and set different threshold values in different regions.In flow process at the beginning, can first judge whether to need switch mode in step S40, the Rule of judgment different according to different application settings, during as the non-use contact panel such as use that in notebook computer keyboard or mobile phone receive calls, carry out step S42 and switch to the second pattern, on this Trackpad, define a plurality of regions, then carry out step S44 and be detected on the object on Trackpad, the position of judgement object on this Trackpad also produces induction area value, carry out again step S46, according to the region at this object place, use threshold value and this induction area value comparison in this region, determine whether false touch, if no error contact represents user and need to use Trackpad to carry out normal running, therefore to step S48, carry out first mode, cancel the restriction of the different threshold values in a plurality of regions, full contact panel is only used a larger threshold value in order to avoid affect normal running, if false touch is repeating step S44, S46, utilize the restriction of different threshold values in the second pattern to improve the probability of false touch.
