Applying a novel visual-to-touch sensory substitution for studying tactile reference frames

Abstract Perceiving the spatial location and physical dimensions of touched objects is crucial for goal-directed actions. To achieve this, our brain transforms skin-based coordinates into a reference frame by integrating visual and posture information. In the current study, we examine the role of po...
