Haptic memory joint angle and the relative location of body. Haptics generally involves active, manual examination and is quite capable of processing physical traits of objects and surfaces. Perhaps the first experiment conducted to study the phenomenon of haptic memory was that of Bliss, Crane, Mansfield, and Townsend who investigated the characteristics of immediate recall for brief tactile stimuli applied to the hand. The results obtained showed a haptic memory store remarkably similar to the visual memory store suggested by Sperling in 1960, with a capacity of approximately four to five items. Similar to tests of visual sensory memory, it was also
Haptic technology haptic vests or haptic suits for use in immersive virtual reality so that explosions and bullet impacts can be felt. Research has been done to simulate different kinds of taction by means of high-speed vibrations or other stimuli. One device of this type uses a pad array of pins, where the pins vibrate to simulate a surface being touched. While this does not have a realistic feel, it does provide useful feedback, allowing discrimination between various shapes, textures, and resiliencies. Several haptics APIs have been developed for research applications, such as Chai3D, OpenHaptics, and the Open Source H3DAPI. Haptic interfaces
