Abstract:
1. An input apparatus for a computer system which comprises: a pointer device operable by a user, and a symbol display system that displays a plurality of input symbols to a user, where said plurality of input symbols represent characters and/or pictogram information content, the symbol display system displaying an array of input symbols defining at least one circuit, and one or more pointer selection sensors configured to sense the selection of a symbol by the pointer device, where the symbol display system also displays at least one commit symbol, said at least one commit symbol being displayed at substantially the center of the focus of an array of input symbols, whereby the input apparatus is configured such that the at least one circuit of input symbols is arranged in a substantially elliptical or circular arrangement such that the user can select a signal input symbol using the pointer device, and directly move the pointer device to the commit symbol without traversing other input symbols such that selection of the commit symbol by the pointer device causes the previous single input symbol only selected by the pointer device to be sent to the computer system.
