Inertial tracking for mobile augmented reality

Augmented Reality applications require the tracking of moving objects in real-time. Tracking is defined as the measurement of object position and orientation in a scene coordinate system. We present a new combination of silicon micromachined accelerometers and gyroscopes which have been assembled into a six degree of freedom (6 DoF) inertial tracking system. This inertial tracker is used in combination with a vision-based tracking system which will enable us to build affordable, light-weight, fully mobile tracking systems for Augmented Reality applications in the future.
