Abstract
A device for providing thermoreceptive haptic feedback includes a first array of low mass elements, arranged in a geometric pattern, the array having a first temperature and a first collective thermal effusivity, and configured for selectively contacting a user, a second array of low mass elements, interspersed among the low mass elements of the first array, and thermally isolated from the low mass elements the first array, the array having a second temperature and a second collective thermal effusivity, and configured for selectively contacting a user, and a means for mechanical switching coupled to the low mass elements of the first and the second arrays and configured to place selected low mass elements of the first and the second arrays in contact with a user, to realize a thermal effusivity between the first collective thermal effusivity and the second collective thermal effusivity.
