Pressure as a tactile response offers a fast and highly accurate interface of information transmission, particularly in the hand, which is highly sensitive in this area.
It has been shown that the blind and deaf can hear simply by placing their hand over a person’s mouth. The already fast reaction to pressure further increases if the stimulus is expected.
With the simple use of vibration, devices should be able to transmit plenty of information to a subject. As age progresses sensitivity to pressure is reduced, but as measured relatively, thresholds do not tend to change.
It is also important to note that spatial awareness as it relates to the sense of pressure is incredibly high. Pressure is a very accurate form of haptic stimulation.
