Method for a virtual thumb keyboard

Disclosed is a method for a virtual thumb keyboard. Benefits include improved functionality, improved performance, improved usability, and improved design flexibility.

Background

              Most desktop computers currently used to today have a single cursor controlled by some method of input, such as a mouse or trackball.

Description

              The disclosed method is a pair of user-controlled cursors on a display device. The software includes operating system (OS) drivers that read the cursor positions/actions from hardware. Additionally, the software provides a set of application program interfaces (APIs) that applications use to drive the cursors.

              Each of the two cursors must be distinguishable from each other. For example, cursors in the shape of a left- and a right-hand, each with a forefinger or a thumb extended to designate the selection point. Alternatively, the cursors could be a pair of arrows, pointing in different directions, with the tip of the arrows designating the selection points.

              An example application is displaying a virtual keyboard on a personal digital assistant (PDA) in an application requiring text input, such as an email or word-processing program. The user could type by moving the cursors around the virtual keyboard. Keystrokes are made by pressing down when the cursor is over the required virtual key. This solution is highly intuitive for typing multi-key combinations on a virtual keyboard (see Figure 1).
