Add Noise
Adds normally distributed noise to eye tracking gaze data.
This filter is useful for testing purposes to stress algorithms and computations under less-than-ideal conditions.
The function takes array of gaze data and configuration. The result is written directly into the gaze data array.
Notes
- This filter may be applied to unsorted data.
Recommended Configuration
- “mean direction” - 0.0
- “mean origin” - 0.0
- “seed” - 0
- “std dev direction” - 0.05
- “std dev origin” - 0.02
