The determination method comprises detecting an object on a touch surface through a sensing element and outputting a detecting frame; calculating the contact range according to the detecting frame through a processing unit; determining the DPI curve according to the contact range.
Description
Technical field
The present invention, can according to the contactor control device of different objects contact area determination dots per inch (DPI) curve and defining method thereof especially in regard to one about a kind of contactor control device.
Background technology
In known contactor control device, such as Trackpad has touch surface and processing unit usually.When user moves in described touch surface with finger, described processing unit can calculate described finger relative to the two-dimensional coordinate position of described touch surface and produce displacement signal.Then described processing unit exports institute displacement signal to main frame and the displacement of the cursor of main frame described in relation control with dots per inch (dotsper inch, DPI) numerical value.
Figure 1A is shown as the schematic diagram of DPI curve, and wherein, x-axis represents the translational speed (unit: inch per second) of object (such as described finger), and y-axis represents the cursor DPI corresponding to described object.DPI curve represents the translational speed of cursor and the relation of dots per inch.When the translational speed of object is slower, such as editing picture, the also less to such an extent as to cursor corresponding to described object of described cursor DPI can move exactly in zonule.And when described translational speed is very fast, such as, playing computer game, described cursor DPI is then larger to such an extent as to described object does not need mobile distance too far away that described cursor can be made to move at a distance.Therefore, use the input media of DPI curve that preferably user can be brought to experience.
But, the finger of different users's (such as adult and child) or or even the difference finger of identical user can change contact range when contacting with described touch surface.Therefore, in the interval of described Trackpad, particularly mini Trackpad, relative to the movable distance of little object, the movable distance of large object can obviously diminish.Such as, please refer to Figure 1B, when the forefinger 93 with less contact range on Trackpad 91 by flatly moving to right side on the left of it, maximum moving distance X can be obtained
93'.When using the thumb 95 of larger contact range on identical Trackpad (being denoted as 91' in this) by the right side of flatly moving on the left of it, another maximum moving distance X can be obtained
95.Apparent, because the contact range of described forefinger 93 is less than the contact range of described thumb 95, its maximum moving distance X
93x can be greater than
95.Whereby, the cursor C on the display screen 81 of corresponding described Trackpad 91 and 91' and 81'
93and C
95then distinguish displacement X
93' and X
95'; Wherein, X
93' >X
95'.Therefore, the shorter meeting of the displacement of larger object causes cursor to move also shorter problem.
