1, y
1), the touch time is T
1The pixel coordinate of touch point B is (x
2, y
2), the touch time is T
2
Distance B between calculating touch point A and the B ' can directly adopt pixel coordinate to calculate; Its computing formula is:
but directly adopt pixel coordinate to calculate the distance between the touch point; When the change, resolution of touch-screen, distance threshold also needs to change thereupon.Therefore, in this embodiment, convert pixel coordinate into physical coordinates earlier, and then the distance between the calculating pixel point, concrete computing method are following:
If the touch-screen width is the W millimeter, highly be the H millimeter; X
MAX=32768, Y
MAX=32768.

2|×H/Y
MAX；
Distance between touch point A and the B
For the mistiming between current touch point and the initial touch point, can be through the touch time of two touch points of record, the mode according to touch Time Calculation mistiming of two touch points realizes then, i.e. mistiming T '=T
2-T
1, T
2The touch time of representing current touch point, T
1The touch time of expression initial touch point.Can also realize through following mode: promptly write down the serial number of touch point in this touch operation, according to the serial number of touch point and the acquisition time interval calculation mistiming of touch point.Gather a touch point information because system is every at a distance from set time t, therefore if the record touch point in this touch operation serial number, multiply by time t again and just can access current touch point and the mistiming of initial touch point time.For example, supposing the system is every gathers a touch point at a distance from 16 milliseconds, 5th touch point of current touch point for gathering in this touch operation, and the mistiming of itself and initial touch point (i.e. the 1st touch point of collection) is T '=(5-1) * 16 millisecond=64 milliseconds.A kind of method is more accurate before the method ratio that differ from this computing time, and its error is a nanosecond.
2. judge said distance B ' and mistiming T ' and pre-set threshold between magnitude relationship.If said distance B ' be no more than predefined distance threshold D and said mistiming T ' is no more than predefined time threshold T (303) then continues to judge whether current touch point is the final touch point (304) of this touch operation.If current touch point is a final touch point, then this touch operation is for starting the right mouse button feature operation; If current touch point is not a final touch point, go to step 1. (305) after then upgrading current touch point with the next touch point of current touch point.If D '≤D and T '≤two relational expressions of T can not be set up simultaneously, then this touch operation is the feature operation of non-startup right mouse button.
