AI Technical Summary

Problems solved by technology

Restrictions are imposed on the user's allowable movement due to the need to use two fingers at the same time
For example, it is very difficult to draw a circle with a finger and a thumb other than a thumb, or with two fingers other than a thumb

Abstract

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.

Description

technical field [0001] Embodiments of the invention generally relate to touch-based user input interfaces for computer systems. Background technique [0002] Touch technology is the latest development in human-machine interface technology for computing and communication devices. Due to the paradigm change brought about by Moore's Law in semiconductor technology, improvements in the speed and response time of computer systems allow users to interface with computer systems using their fingers. [0003] The keyboard was an early form of user input interface for computers. It migrated naturally from the typewriter world. The mouse is added to the user interface as another natural and faster means of user input. It is worth noting that the main driver of this progress is the development of silicon technology, which enables the support of graphical user interfaces. Rather than specifying text entry, the rapid movement of the cursor on the screen in response to mouse movements ...
