Virtual keyboard for touch-typing using audio feedback

A computer-readable medium having computer-executable instructions for a computing device to perform steps to provide a virtual keyboard for user interface, the steps comprising:

• displaying a keyboard image on a touch sensitive screen, the keyboard image having a plurality of key images corresponding to individual keys;
• receiving a signal indicating a location of a detected touch on the touch sensitive screen;
• determining whether the detected touch is on one of the key images of the keyboard image;
• if the detected touch is on a key image, generating a sound according to a deviation of the location of the detected touch from a target portion of the touched key image to where the detected touch is in relation to the target portion of the touched key image.

A computer user interface device comprising:

• a touch sensitive screen;
• a processing unit for executing computer-executable instructions;
• an audio output device;
• a software control program having computer-executable instructions to be executed by the processing unit to display a semi-transparent keyboard image having a plurality of key images corresponding to individual keys on the touch sensitive screen over a background image, receive a signal indicating a detected touch on one of the key images of the keyboard image displayed on the touch sensitive screen, generate a sound using the audio output device to indicate that a keystroke is received, and alter a look of the touched key image to indicate that the keystroke is on the touched key image, the keyboard images corresponding to keys for at least a complete set of letters in an-alphabet and arranged in a layout and sizesuitable for “ten-finger” touch-typing, each key image having at least one shaded edge.
