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.
