1. One or more non-transitory computer readable storage media comprising instructions that, when executed by a computer having one or more sensors and associated with a head-mounted display apparatus, are capable of causing the computer to:

  • a. generate a virtual environment with a ground plane structure;

    b. generate a signal to establish a location of a virtual camera in the virtual environment;

    c. generate a signal to establish an orientation of the virtual camera in the virtual environment;

    d. generate a signal to update the location of the virtual camera in the virtual environment in a direction of the orientation of the virtual camera on a plane parallel to the ground plane structure using x-axisometer data from at least one of the sensors indicating pivot up or pivot down of the head-mounted apparatus and an x-axisometer sensor reference data, wherein said use of x-axisometer sensor data to update the location of the virtual camera is effectively decoupled from use of v-axisometer sensor data, thereby enabling v-axisometer sensor data of the computer to be used independently of x-axisometer sensor data of the computer to update the orientation of the virtual camera; and

    e. generate a signal to update the orientation of the virtual camera in the virtual environment using v-axisometer data from at least one of the sensors indicating pivot left or pivot right of the head-mounted apparatus and a v-axisometer sensor reference data, wherein said use of v-axisometer sensor data to update the orientation of the virtual camera is effectively decoupled from use of x-axisometer sensor data, thereby enabling x-axisometer sensor data of the computer to be used independently of v-axisometer sensor data of the computer to update the location of the virtual camera.
