Instantaneous Angular Gaze Velocities
Computes instantaneous angular gaze velocities.
The velocities are calculated to be the deltas between two adjacent frames. All angles are reported relative to the user’s ’nose vector'.
The function takes three arrays of matching timestamps, gaze and output. All arrays are required to be the same size. This function must not be used on data with non-monotonic time stamps. The result is written into the output array.
Notes
- This filter must be used on data with monotonic time stamps.
