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 type of physical haptic feedback. Disney took on this research because they believed that technology is advancing towards more virtual or augmented reality applications. According to Disney, the missing piece in this emerging computer-augmented world is the absence of physical feeling of virtual objects. Disney's main intention for this research was to encourage other research regarding new applications of non-contact haptic feedback. In 2013, Microsoft explored the same area as Disney. They used air vortex rings in order to try and provide haptic feedback for an at-a-distance interaction. Microsoft mostly focused on the study of vortex formation theory and parameters
