Realize that amplifying operation is similar to touch screen is scaled outward by finger.
If the change in location trend of continuous touch-control coordinate point shows as ecto-entad variation on touch screen, explanation can not
It is that ecto-entad uninterruptedly irradiates that light-exposed light beam, which is radiated at the mode on touch screen, then the control behaviour to be reduced to touch screen
Make.Realize that reduction operation is similar to touch screen is inwardly scaled by finger.
Each point has a unique coordinate points on touch screen, coordinate origin can be quadrangle on touch screen or in
Heart point, also or on touch screen any point can be coordinate origin；After coordinate origin determines, all the points on touch screen
Coordinate points and determined, and the variation tendency between coordinate points be it is regular, pass through the coordinate points calculated of judgement
Variation tendency so that can judge to operate in the control that amplifies touch screen or reduces.
It is described click it is as follows with the control operating procedure of long-pressing:
If discontinuous between each touch-control coordinate point, judge the mutation current signal generated at touch point there are the time with
Relationship between the default response time；
If the mutation current signal is less than there are the time presets the response time, illustrate the control to be clicked to touch screen
