Tactile simulation is a very important part of immersive construction. The current tactile technology may be only slightly more mature than vibration simulation. However, this method is relatively "rough." If you want to rise to "detail", such as texture simulation, it will take a lot of effort. Earlier, Microsoft also proposed a texture analog haptic feedback controller, but such controllers require large amounts of data support.
In the United States, the company SynTouch developed a sensor in 2013 that can simulate multiple sensing methods at the human fingertips, thereby collecting the haptic information of the material and providing it to the robot to determine the touched object. Now the company uses the technology to create a system that categorizes tactile information into 15 dimensions. They call it SynTouch Standard. It is worth mentioning that instead of developing tactile feedback devices, they collect these tactile information and then provide it to other virtual reality companies and work together to create a tactile feedback device that can use computers to simulate various textures. SynTouch listed Oculus as one of their partners and also provided data to other unpublished tactile simulation companies.
The SynTouch Standard system has a high range of tactile information, and the 15 dimensions encompass the five major attributes of texture, softness, friction, heat, and viscosity. The study was originally initiated by the US Department of Defense Advanced Research Projects Agency to increase the touch feeling of the prosthesis. SynTouch is also keen to find that their technology can also provide a lot of insight and value for the virtual reality field. They hope to work with more companies in different tactile fields to solve some of the most difficult engineering problems on haptic devices.
