Machine vision, optionally paired with radial range finder like a VOR/DME would solve this easily. The latter could be done
visually with an IR beacon beany. Machine vision and human pose recognition can easily track a walking human now.
Clearly, this is needed for God-mode video capture (back country mountain biking etc.) and smite-thee-bully protection. Allow
manual switchover to your guardian angel buddies for video game strafing as needed, upon panic button.
