ABSTRACT:
A method and an apparatus for speech controlled navigation of a pointer in a graphical user interface. Previous methods use speech commands like arrow keys of a keyboard and lack user friendly interfaces. The method and apparatus therefore provides a space of discrete position states (quantization) for the pointer which can be navigated only via those discrete positions by means of speech command input. The granularity of the discrete position states can be adapted to the respective application window and the position states can be represented by a system of coordinates where the speech command input is based on absolute or relative coordinates. Advantageously a copy image of the graphical user interface of operation can be provided in front of or beside the actual user interface and a proxy pointer device is displayed on the copy image. In one embodiment, only the copy image comprises the discrete position states, and the speech input commands are only transferred to the copy image. Navigation of the proxy pointer device within the copy is transferred and converted into commands within the actual user interface. By this method, an operation event effected by a manipulation of the proxy pointer effects a corresponding event at the user interface.
