Virtual reality is a slow-moving field in some respects. While a lot of focus is put on optical technologies and headsets, there’s a lot more involved when it comes to believably placing a human being in a virtual environment. So far, we’ve gotten a good start at the visuals and head tracking, but interaction technology is still lagging behind a lot. [Lucas] is working in just that area, iterating heavily on his homebrew VR gloves.
The gloves consists of potentiometers, fitted with spools and attached to the tip of each digit on a wearer’s hand by a string. As the user curls their fingers, the potentiometers turn and the position of the fingers can be measured. The potentiometers are all read via an Arduino, which communicates back to a PC via USB. A custom driver is then used to interact with Valve’s SteamVR software, allowing the glove to be used with a wide variety of existing software.
Thus far, the system is merely tracking finger position, but the spool and string based design is intended to support motors down the line for each finger to create resistance, so the user can gain the feeling of touching and interacting with virtual objects. The project has the potential to be a cheaper, more accessible alternative than current off-the-shelf solutions. We’ve seen other hand-tracking gloves before, too – though none that track the spread of a wearer’s hand as well as the finger extension. If you’re working on precisely that, please do drop us a line. Video after the break.
