ABSTRACT:
A computer system enables a user to design touch activated keyboards for use on a display surface without writing code. The computer system enables the user to resize and move the keyboard image anywhere on the display to allow the concurrent display of other applications running in an integrated operating environment. Computer system actions can be assigned by the user to each key. An execution unit displays the selected keyboard, determines whether a key has been touched and executes the appropriate action for each key touch.
