Vibrotactile

A form of tactile feedback that uses mechanical vibrations applied to the skin to convey information. Vibrotactile stimulation typically operates at frequencies between 10-500 Hz and is perceived through mechanoreceptors in the skin. In assistive technology, vibrotactile feedback is used in sensory substitution systems, navigation aids, and notification devices. Unlike electrotactile stimulation which uses electrical current, vibrotactile feedback is generally considered safer and more comfortable for extended use, though users may experience sensory adaptation (desensitization) over time. Common vibrotactile actuators include eccentric rotating mass motors, linear resonant actuators, and piezoelectric devices.
