Magnets could soon track your fingers in virtual reality
In an ideal world, you'd grab objects in virtual reality with your hands, like you do in real life. However, that's not usually how it works -- outside of some specialized gloves, you're left using abstract controllers. Oculus and University of Washington researchers might make it a reality, though. They've developed Finexus, a control method that uses a combination of fingertip electromagnets and sensors to track your hands. The system detects the distances between each finger and the sensor, and uses the intersection of each distance to determine a given digit's exact 3D position. Unlike with camera tracking, you don't need a direct line of sight to the sensors for this to work -- you could tie your virtual shoelaces if you wanted.
