ABSTRACT:
The disclosure relates to a multifunctional (control, typing and editing) device for interactive computing, such as Web and Web TV computing. It consists of a frame, two removable letter keypads, and different sizes of hand extensions that can be attached to the sides of the frame. The frame consists of two rectangles of different sizes that are permanently attached to one another. The lower rectangle is narrower and thinner than the upper rectangle. On the upper, wider and thicker, rectangle are permanently positioned some function and control keys to be accessed primarily by the thumbs. The lower rectangle contains two square compartments into which can be placed the removable letter keypads. The keypads contain active keys on one side and the images of the active keys on the other side. Depending on how the keypads are positioned into the compartments the active keys can be accessed either from the front or from the back of the device, thus allowing for two completely different ways of typing.
