perceiving the lengths of real and virtual objects using kinesthetic touch
Humans use their kinesthetic haptic sense for a variety of day-to-day tasks. While manipulating objects using this sensory channel, which corresponds to signals arising in the muscles and joints, it has been shown that humans can perceive several characteristics of the objects that are being held or wielded. For example, the length of a baseball bat can be estimated without but the aid of vision by wielding it. There have been over a hundred studies that have sought to understand the perceptual basis of these judgments. Seminal work conducted by [7] and [8] has suggested that the haptic perception of length during wielding is related to the Inertia tensor of the wielded object. Studies have shown high correlations between the inertia tensor and various haptic properties like length [1], height [9, 10], orientation of the object [3] and the position of the hand grasp [4, 5]. All of these studies have shown the central role of the inertia tensor as the perceptual basis for making haptic judgments of object properties.
