Haptic technology HD Rumble feature (similar to Valve HD Haptics). It has a high level of precision, allowing it to simulate the feel of holding, moving and using objects. "1-2-Switch" has a number of minigames demonstrating this feature. In 2008, Apple's MacBook and MacBook Pro started incorporating a "Tactile Touchpad" design with button functionality and haptic feedback incorporated into the tracking surface. Products such as the Synaptics ClickPad followed thereafter. In 2015, Apple introduced "Force Touch" trackpads onto the 2015 MacBook Pro which simulates clicks with a "Taptic Engine" (which provides haptic feedback). Tactile haptic feedback is common in cellular devices. Handset
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
