A location tracking apparatus and method of tracking are disclosed. The location tracking apparatus includes a tip configured to move on a surface, a tracking instrument, and a frictionless sensor associated with the tip. The tip is configured to undergo a displacement within a limited range when the tip is pushed to the surface, or when the tip is moved away from the surface, so that the tip maintains contact with the surface while moving on the surface. The tracking instrument is configured to generate location data. The frictionless sensor is configured to generate displacement data.
