Magnets could soon track your fingers in virtual reality
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.
