Create binocular event detection filter

[dkrako]

Description of the problem

The implemented eye tracking algorithms usually use a single eye for eye movement detection. However, some eye movement events happen on both eyes simultaneously, so we need a method that filters out eye movements that occur only on one eye.

Description of a solution

• [ ] implement binocular event filter
• [ ] create test cases and make them pass

Minimum acceptance criteria

• [ ] a binocular event filter with passing tests
