Haptic technology unit. More specifically, the patent provides for one actuator to induce a feedback vibration, while at least one other actuator creates a second vibration to suppress the first from propagating to unwanted regions of the device, thereby "localizing" the haptic experience. While the patent gives the example of a "virtual keyboard", the language specifically notes the invention can be applied to any multitouch interface. Haptics are gaining widespread acceptance as a key part of virtual reality systems, adding the sense of touch to previously visual-only interfaces. Most of these use stylus-based haptic rendering, where the user interfaces to the virtual
Haptic memory stimuli. According to a study done by Bruce V. DiMattia, Keith A. Posley and Joaquin M. Fuster, it was found that monkeys were quite capable of concurrent Visual-to-Haptic as well as Haptic-to-Visual crossmodal matching of objects by size, shape and texture. It was also discovered that they were more adept at performing cross modal matching in the Visual-to-Haptic direction. Memory is important in infancy as it forms the basis for more complex procedures such as learning and reasoning. Studies of haptic memory in infants is particularly useful because it allows researchers to study the more perceptual representation of information as
