Touch is an unavoidable topic when it comes to virtual reality. You can raise the resolution of the VR headsight to the highest possible level, or extend the frame rate to the comfort zone as possible... but when the user reaches out and wants to touch the object but has nothing at all, the immersive sense of virtual reality It will break.
At a recent TechCrunch Sessions: Robotics conference, a researcher at the Massachusetts Institute of Technology demonstrated a portable “shape monitor,†a surface or object that can move with the hand and simulate the user’s virtual avatar. Wheeled robot. He called it the "ReVeal" system.
If this looks familiar, you may remember TRANSFORM, another project from the MIT Media Lab. The two items have in common, all use the same type of change-for-pin array, but TRANSFORM is a large platform designed to be fixed in the same location. ReVeal can move with the hand in the real world and simulate the corresponding touch in the VR/AR world. This mobility makes it possible to simulate objects in larger environments, rather than being limited to only a few feet wide.
Like all haptic solutions, ReVeal has its own limitations. For example, the "resolution" of tactile sensation can only be increased to a certain level (more pins are added in the same area) because the higher the "resolution", the smaller the pin needs to be, ie the more pointed.
Want to start with one? Inventor Daniel Fitzgerald (Daniel Fitzgerald) said that at the moment it is purely a research project and there is no plan for commercialization or deployment outside the laboratory.
