Method for making precise gestures with touch devices

摘要

A method for operating a data processing system to implement a gesture on a touch enabled display is disclosed. The method causes the data processing system to determine a position of a contact object on the touch-enabled display as a function of time. The data processing system provides an offset indicating a distance through which a point shown on the display is to be moved in response to the determined position. The offset has a first value in a normal mode and a second value in a precise gesture mode. The value in the precise gesture mode is less than the value in the normal mode. The data processing system automatically changes from the normal mode to the precise gesture mode in response to changes in the determined position as a function of time. Exemplary changes utilize changes in direction or the speed of motion of the contact object.

1. A method for operating a data processing system to implement a gesture on a display, said method comprising:
causing said data processing system to determine a position of a contact object on said display as a function of time; causing said data processing system to provide an offset indicating a distance through which a point shown on said display is to be moved in response to said determined position, said offset having a first value in a normal mode and a second value in a precise gesture mode, said second value being less than said first value; and causing said data processing system to automatically change from said normal mode to said precise gesture mode in response to changes in said determined position as a function of time.
