Does Sensory Adaptation exist for force feedback?

Yes for vibrotactile

Does Sensory Adaptation exist for force feedback?

Method

Press “space” when a diminishing force is felt.

Method

Press “space” when a diminishing force is felt.

Stimulus

$Torque(t)=A\exp\left(\frac{-(t-b)}{\tau}\right)$

Participants
