Motion sensors display data concerning your headset’s position and orientation using a combination of absolute orientation (magnetometer), acceleration (accelerometer) and rotation vectors () data in a ten channel time series graph. Select “MOTION SENSORS” in the left side menu to access this view.

Alternatively, for your EPOC+ devices, you can choose to view a 3D visualisation of the motion sensor represented by a cube. The 'cube' represents accurate rotation of the device along X, Y and Z axes. The user can 'Calibrate' the cube by turning the headset on and clicking the 'Calibrate' button which sets the cube to Position 0. The 'mirrored' display is checked by default so that the pink marker points towards the user when headset is worn correctly. If the mirrored option is unchecked, the pink pointer faces away from the user and the blue marker points towards the user.

The 'Rotation' gauge on the left represents cube rotation along Y axis and can also be called pointing direction. With position 0 set arrow in vertical position. That 'Roll' gauge in the middle represents rotation of the cube along Z axis, and can also be described as roll left or right and is seen as a from the top view where pink and blue dots on the gauge stay in the fixed position. Position 0 is when line set in horizontal position on the gauge. The 'Pitch' gauge on the right represents cubes rotation along X axis, can also be described as tilt up or down. Position 0 is when the arrow is set in a horizontal position on the gauge.

For older EPOC+ headsets, (Firmware <0x633) motion sensors display data concerning your headset's position and orientation using a (gyroscope), acceleration (accelerometer) and absolute orientation (magnetometer) measurements.

*Note - Epoc Flex does not support Motion data currently
