Second step, definite the second coordinate figure of simplifying point.
If in the subpoint of the projection line that the composition view field determined overlaps with touch-screen screen sideline, another coordinate figure of any one subpoint is also 0 or MAX just, this subpoint can be defined as simplifying a little, and can determine thus the second coordinate figure of simplifying point.
If in the subpoint of the projection line that composition view field overlaps with touch-screen screen sideline, another coordinate figure that the neither one subpoint is corresponding is 0 or MAX just, can calculate all composition projection lines subpoint another coordinate figure mean value and round, perhaps get the maximal value of another coordinate figure of subpoint of all composition projection lines and the mean deviation of minimum value and round, thereby be simplified the second coordinate figure a little.
Determine the first and second coordinate figures of simplifying point by the first step and second step, thereby can determine and simplify the position of point in the touch-screen screen.
Determine that the method that touches reference point is identical with the method in embodiment mono-, can determine the described projection line of view field's middle distance or subpoint point farthest to the distance of line segment or the distance of point-to-point by point, and using this point as the touch reference point of determining.
Further projection line is being reduced to while simplifying point, in this step can according to point-to-point apart from computing formula, determine in view field with the distance point farthest of simplifying point for touching reference point.Preferably, can calculate respectively the horizontal ordinate and the ordinate that touch reference point, the distance of take is simplified some horizontal ordinate abscissa value farthest as touching the abscissa value of reference point, and the distance of take is simplified some ordinate ordinate value farthest as touching the ordinate value of reference point.
Whether step 205, definite operation of clicking actual touch point are legal operations.
Determine in this step that whether the actual click operation is that the verification method of legal operation is identical with embodiment mono-, does not repeat them here.
It is to be noted, in practical operation, be subject to infrared transmitter and infrared receiver that the impact of quantity is installed, the touch reference point locations of being determined by the infrared ray sensing method and user's actual touch point may have certain distance, except can setting suitable first threshold, can also represent that touches a reference area by the touch reference point identified, the size of described touch reference area can be according to the position dynamic setting that touches reference point, as long as the position of the touch reference point identified is in this touch reference area, can be when identifying this touch reference point, as long as determine that the distance between actual touch point and touch reference area is less than the 3rd threshold value of setting, can determine the legal operation that is operating as of clicking described actual touch point, otherwise, determine the illegal operation that is operating as of clicking described actual touch point.
