Abstract
This paper describes a novel method to indicate tactile sensation using surface acoustic wave (SAW). A stator transducer material of a SAW tactile display, however, has constraint of size and shape. To solve this problem, the glass substrate SAW tactile display is proposed. To improve energy efficiency, a wave-circulating surface acoustic wave transducer is proposed. In the structure, the wave excited by the oscillator can circulate around the substrate surface. In this research, a tactile mouse, which is a computer mouse with the wave-circulating transducer, is proposed. Fabrication and characteristics of the tactile mouse are reported and its works successfully.
