Hands-on: HaptX Glove Delivers Impressively Detailed Micro-pneumatic Haptics, Force Feedback
The company formerly known as AxonVR, which has raised more than $5 million in venture capital, is rebranding to HaptX, and revealing a feature prototype of a VR glove which uses micro-pneumatics for detailed haptics and force feedback to the fingers. After trying the prototype for myself, I came away impressed with the tech. The company’s next challenge is to turn the prototype into something sleeker, smaller, and far more practical.
The HaptX gloves is based on innovative micro-pneumatic technology. The company has developed a method for essentially producing thin, bendable fabrics which are manufactured with a series of tiny air pipes along their length which eventually terminate in small inflatable circles which act as “haptic pixels,” according to Jake Rubin, one of the company’s two co-founders and its CEO. The inflatable circles, just a few millimeters across, are aligned into grids; by precisely controlling when and which haptic pixels to inflate, a convincing sensation can be created, simulating the feeling of an insect crawling along your finger or a marble rolling around in the palm of your hand.
The glove also features force feedback: the ability to restrict the movement of your fingers to simulate holding objects
Each of the glove’s fingers is tracked by a proprietary magnetic tracking system which Rubin claims is capable of sub-millimeter precision. Indeed it worked well.
Eventually a baseball-sized tractor came rolling out of the barn. When I went to pick it up like a little toy, my fingers stuck in place—seemingly right against the virtual tractors surface—and wouldn’t budge. It was a convincing effect,...
