PATCH: Haptic perception and touch - Vincent Hayward

Computational Theory of Haptic Perception

We perceive our environment through mechanical interaction since we perceive it using acoustics and optics. Some progress has been made towards the discovery of the mechanisms that lead to conscious sensations resulting from contact with mechanical objects. This progress is due in part to the availability of new tools that can precisely control the stimulation of ascending sensory pathways and descending motor pathways.

The research program includes the design of new mechanical stimulation devices capable of generating haptic signals at multiple spatial and temporal scales. The goal is to produce well controlled stimuli with the ease and precision that is now possible when studying the vision or hearing. The purpose of this equipment is to segregate and recombine the perceptual cues used by the brain to lead to the identification of the calculations necessary for a perceptual outcome. Vision and hearing, the calculations made by the central and peripheral systems are relatively well known, but because of a lack of adequate technical capabilities, the equivalent knowledge of the somatosensory system is largely absent.


 

We aim to develop a theory of haptic perception based on the observation that these calculations are distributed in the physics of contact mechanics, in biomechanics, in the innervation of the extremities, as well as in the central neural processes. This research program is rich in applications ranging from improved diagnosis of diseases, rehabilitation devices, the development of haptic interfaces now part of consumer products, and virtual reality systems.

 

Vincent Hayward also won a ERC "Proof of Concept" grant, which gives the opportunity to develop research applications for industrial and commercial use. Read the full article on the INS2I CNRS site. Read the full article on the CNRS INS2I siteNouvelle fenêtre.
