- Abstract
- Perceiving when an object is about to slip off the hand is essential in dexterous manipulation. Indeed, it enables a quick adjustment of the grip force in order to prevent object drop. Prior to full slip between the finger and the object, partial slips occur at the periphery of the fingertip-object contact. While these partial slip events have been extensively characterized, the perception of such events remains unclear. Here, we designed a psychophysical experiment to assess human ability to detect partial slips. We show that the actual slipping state of the fingertip-object contact is the best predictor of the perceived slip, which confirms that humans can actually perceive partial slips and supports the hypothesis that such events can be used during dexterous manipulation.
