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 technology flight simulators for pilot training. It is very critical to exert proper force magnitude to the user. It requires considering human force sensitivity. Haptic feedback is commonly used in arcade games, especially racing video games. In 1976, Sega's motorbike game "Moto-Cross", also known as "Fonz", was the first game to use haptic feedback which caused the handlebars to vibrate during a collision with another vehicle. Tatsumi's "TX-1" introduced force feedback to car driving games in 1983. The game "Earthshaker!" was the first pinball machine with haptic feedback in 1989. Simple haptic devices are common in the form of game controllers,
