You can turn individual Motion Sensor streams on and off in the view to focus on the data you are most interested in. To do this:
Click on the eye icon in the top right corner of the view
Deselect any data stream that you do not want to see
Select any data stream that you want to see
Click outside of the popup to close and return to the main view
The resolution of Motion Sensor data for EPOC is 128 Hz and 12-bits, and for INSIGHT headsets is 64 Hz and 14-bits. The resolution for EPOC+and EPOC X is 16-bits and can be 32 or 64 Hz (or OFF) depending on the headset’s and whether or not it is connected via Bluetooth. When EPOC+ or EPOC X is connected to Bluetooth, the rate is limited to 64 Hz. For EPOC Flex, the resolution is 8 bits and the sampling rate is 16 Hz. EPOC headsets include GyroX and GyroY sensors only. X-axis is samples.
You can toggle all Motion Sensor on and off in the Motion Sensor view. To do this:
Click on the eye icon in the top right corner of the view
Click on Toggle All button in the pop up
Click outside of the popup to close and return to the main view
Motion sensor graphs include 10-axis motion sensors for Insight and EPOC+ headsets:
Quaternion 0, 1, 2, 3 - quaternion data in X, Y and Z directions and absolute quaternion values
AccX, AccY and AccZ - accelerometer in X, Y and Z directions
MagX, MagY and MagZ - magnetometer in X, Y and Z directions
Motion sensor graphs for older Insight and Epoc+ headsets (firmware < 0x633) include 9-axis motion data:
GyroX, GyroY and GyroZ - gyroscope in X, Y and Z directions
AccX, AccY and AccZ - accelerometer in X, Y and Z directions
MagX, MagY and MagZ - magnetometer in X, Y and Z directions
Motion sensors display data concerning your headset’s position and orientation using a combination of absolute orientation (magnetometer), acceleration (accelerometer) and rotation vectors (quaternion) 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
