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 by a fingertip, as a programmable function of the finger's motion. The TPaD Tablet Project uses an ultrasonic technology to modulate the slipperiness of a glass touchscreen, as if a user's finger is floating on a cushion of air. In February 2013, Apple Inc. was awarded the patent for a more accurate haptic feedback system that is suitable for multitouch surfaces. Apple's U.S. Patent for a "Method and apparatus for localization of haptic feedback" describes a system where at least two actuators are positioned beneath a multitouch input device to provide vibratory feedback when a user makes contact with the
