Abstract: Methods and systems are provided for head mounted display (HMD) implementations. One example implementation, a HMD includes a circuit for communicating with a computing system that processes multimedia content for display in the HMD. Further included is a front unit of the HMD that has a screen for displaying multimedia content, and the front unit has a set of LEDs. The HMD includes an accelerometer and gyroscope disposed in the front unit of the HMD. A rear section of the HMD is provided having a set of LEDs. A headband connecting the front unit to the rear section is included, such that adjustment of the headband changes a separation distance between at least one of the set of LEDs of the front unit and at least one of the set of LEDs of the rear section. Wherein calibration of the separation distance is performed from time to time to produce and estimated separation distance for tracking of the HMD during use.
