SINGLE TOUCH PROCESS TO ACHIEVE DUAL TOUCH EXPERIENCE FIELD

摘要

A process to experience a two touch interface with single touch functionality is disclosed. Use of two fingers simultaneously presents a degree of freedom constraint on the hand. In an embodiment of the present invention, the simultaneous two touch interface is simulated using a single touch process. In a special input mode, a mechanism is used to first fix a point of reference. A second and subsequent single touch with respect to the fixed point of reference is then made. The time skewed touches enable free use of the index finger for both touches. Closed figures are easily drawn and zoom in and zoom out functions are similarly implemented by a point of reference and a line traced away from or to the object. Limitations of the dual touch are overcome, while maintaining full interface capability of the dual touch.
