This paper presents new pointing device based on the principle of supersonic position measurement by phase difference. Any kind of motor action by users are available to pointing by the device, and it allows computer users various pointing styles including “mouse-like” one.
The principle and the formulae of supersonic position measurement are introduced. Trial construction of the pointing system is described. And performance of the pointing system is investigated using test system constructed with X-Y plotter. Finally some seamples of pointing devices with various pointing styles are realized, and experiments on the efficiency of pointing tasks with computer users are carried out to validate that the pointing system is suitable for practical use.
