Wearable Haptics / Cutaneous devices / Mechano-tactile devices / Skin devices / Cutaneous-Kinesthetic dissociation / Sensory subtraction / Needle insertion: the research so far in our SIRSLab



This short post summarizes the research on wearable haptics and sensory subtraction in the recent years. The wearable cutaneous devices we have developed are presented in [1]. We have used them in several applications but the most relevant work employing them, which aims at comparing the performance of kinesthetic and cutaneous feedback, is [2]. In [2,3] we analyzed the performance of cutaneous and kinesthetic feedback in a simple teleoperation task (needle insertion in 1 DoF) pointing out how cutaneous feedback can improve the overall safety of the system. After that, we have developed other types of cutaneous devices. For instance the one presented in [4] can be attached to the end-effector of commercial kinesthetic devices (such as the Omegas) in order to be able to easily switch between cutaneous + kinesthetic and cutaneous only.

To get wearability in haptics it is very important to deal with the skin. Devices we are developing are able to apply cutaneous forces without  kinesthetic force feedback. This is of course an issue but it is mandatory if we want to have wearable device. It is a requirement for the design of the devices. Which are the errors we get in using cutaneous only stimulation instead of kinesthetic feedback? To which extent we can avoid kinesthetic feedback ? An answer to this questions has been provided in [6] in cooperation with K. Minamizawa, who developed the gravity grabber which inspired our research on wearable haptics.
