Pen tablet type surface acoustic wave tactile display integrated with visual information

This paper describes development of a pen tablet type surface acoustic wave (SAW) tactile display. Combination of the device with a pen tablet LCD device is proposed. The role of the device is to detect pen position and to provide visual information. This paper presents principle of the SAW tactile display and its application to pen tablet interface integrated with visual information. The combination to realize our proposal is also indicated. Demonstration method and measurement result of mechanical vibration of the pen are also reported.

Pen type surface acoustic wave tactile display with movable tablet

Recently, pen-tablet interface for PC has been commercialized. Using the device, its user can draw a line on it as well as point icons like a mouse. During such operation, users can feel only smoothness on the top of the pen. They cannot recognize the completion of the operation, because of no tactile sensation feedback. In this research, tactile feedback through the pen is proposed. The operators can feel drawing sensation similar to the feeling when they draw a line with a charcoal on a drawing paper. To realize the feedback, principle of surface acoustic wave (SAW) tactile display was applied. A movable tablet with a SAW transducer was designed and fabricated. With the transducer, tactile feedback can be enjoyed on whole PC screen.

Tactile mouse using friction control

This paper describes a novel method to indicate tactile sensation through a PC mouse using friction control applying surface acoustic wave (SAW). For the friction control, a wave-circulating SAW transducer is proposed. In the structure, the wave excited by the oscillator can circulate around the substrate surface to improve energy efficiency. In this research, a tactile mouse, which is a computer mouse with tactile feedback, is proposed. The tactile feedback applying the friction control is described. The friction between the mouse and a mouse pad can be controlled by mechanical vibration of the SAW. Fabrication and characteristics of the SAW transducer are indicated. Successful work of the tactile mouse is also reported.

Pen tablet type surface acoustic wave tactile display combined with Phantom

This paper describes development of a pen tablet type surface acoustic wave (SAW) tactile display. Combination of the device with a Phantom is proposed to control the display. The role of the Phantom is to detect pen position and to guide the pen inside the indication area of the display. This paper presents principle of the SAW tactile display and its application to pen tablet interface. The combination to realize our proposal is also indicated. Demonstration is reported to show effectiveness of the developed device.
