Vibrotactile Feedback

A form of haptic feedback that communicates information through vibration patterns delivered to the skin, typically via small motors embedded in wearable devices such as armbands, gloves, or watches. Vibrotactile feedback offers an alternative sensory channel for conveying information to blind and visually impaired users without occupying the auditory channel used by screen readers. Parameters that can be varied include vibration intensity, duration, rhythm, frequency, and body location, enabling the design of rich information-encoding patterns called Tactons.
