Measurement of Tactile Sensation by Vibrometric Technique
نویسنده
چکیده
The ability to quantify the sensation of vibration is a valuable indicator of the state of tactile sensory system. Elevated threshold in the detection of vibratory stimuli may be the first sign of neuropathological disorders. Mechanoreceptive units are responsible for vibrotactile sensation of the skin, and different types of these units respond to different frequencies. Vibrometry is based on the physiology of vibrotactile sensation of the skin. This study attempts to establish the technique that applies vibratory stimuli at various frequencies to measure the threshold of vibratory sensation at the finger-tip.

Objective Evaluation of Tactile Sensation for Tactile Communication
We humans use the five senses of “sight, sound, touch, taste and smell,” to interact with other people and various objects around us. While remote communication with video and speech have become familiar to us lately, DoCoMo is currently working on research aiming at finding ways to communicate via tactile sensation, which is believed to be important in terms of information volume, which comes ...
متن کاملPresentation of Softness Using Film-Type Electro-Tactile Display and Pressure Distribution Measurement
Electro-tactile display has simple mechanical structure and it can present tactile stimulus. However, electro-tactile display lacks of feedback corresponding to touching motion. In this research, we developed a device that combines an electro-tactile display and pressure distribution sensor. The device not only solves problem of unnatural electrical sensation, but also enables expression of hap...

متن کاملFood vibrations: Asian spice sets lips trembling.
Szechuan pepper, a widely used ingredient in the cuisine of many Asian countries, is known for the tingling sensation it induces on the tongue and lips. While the molecular mechanism by which Szechuan pepper activates tactile afferent fibres has been clarified, the tingling sensation itself has been less studied, and it remains unclear which fibres are responsible. We investigated the somatosen...
