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 technology a Boston University paper published in "The Lancet", "Noise-based devices, such as randomly vibrating insoles, could also ameliorate age-related impairments in balance control." If effective, affordable haptic insoles were available, perhaps many injuries from falls in old age or due to illness-related balance-impairment could be avoided. In February 2013, an inventor in the United States built a "spider-sense" bodysuit, equipped with ultrasonic sensors and haptic feedback systems, which alerts the wearer of incoming threats; allowing them to respond to attackers even when blindfolded.
