ABSTRACT:
A presentation supporting device having excellent operability and adaptability to oral presentations in a computer multimedia environment. First and second accelerometers detect first and second acceleration of gravity resulting from inclinations in first and second sensitivity axis directions perpendicular to each other to output first and second acceleration signals, and first and second signal processors process the input first and second acceleration signals to output cursor moving control signals for controlling moving speeds and moving directions in the first and second coordinate axis directions of a cursor on a computer display screen in response to voltage values and polarities of the first and second acceleration signals.
