Title: Multisensory Perception of Soft Objects

Abstract
Softness is the subjective impression of the physical deformability of an object. When we interact with a deformable object like a pillow, sensory signals from multiple sense modalities provide information related to its compressibility (i.e. proprioceptive position, tactile force, visual deformation). Such signals dynamically depend on the way we interact with the object. Our brain has specialised mechanisms that processes this information to create a coherent perceptual representation of the compressibility of the object and to adjust motor actions accordingly. In this work I will present psychophysical experiments that employ visual-haptic virtual reality setups to investigate how we perceive the compressibility of an object while we squeeze it or while we press against its surface. The results of these studies form the basis of a computational model of softness perception where signals are combined into perceptual estimates that are then integrated according to the rules of Bayesian inference.
