I'm not sure the practical uses of the HIRO III, but it sure is neat. Essentially, it's an interface device that you stick your fingers in, allowing you to feel stuff on a computer.
It's basically a robotic hand that you attach your fingers to, with it simulating the size, shape, weight and texture of whatever you're interacting with on-screen. The most obvious non-porn use for this would be gaming, especially with a 3D display, although it looks too complicated and expensive to catch on as a mainstream peripheral.
But it could surely be used in other scenarios where having a more sensitive touch would be beneficial, like controlling surgery robots and things of that nature. In any case, neato. [Switched via TFTS]
