Vibrotactile thresholds are sensory thresholds in tactual perception concerned with the detection of vibration and touch in various forms. The thresholds studied include

  • Vibrotactile absolute threshold: the lowest level at which a stimulus can be detected.
  • Vibrotactile recognition threshold: the level at which a stimulus can not only be detected but also recognised.
  • Differential threshold the level at which an increase in a detected stimulus can be perceived.
  • Vibrotactile terminal threshold: the level beyond which a stimulus is no longer detected.

  • Mimimum level of vibration that can be detected.
  • Minimum change between compared stimuli that is detectable.
  • Minimum change in one stimuli that is noticeable.
