    Question about sampling frequency.
    per the spec summary sheets, 4c 5 differences

    Tobii 4 (C,L) = 90Hz – interlaced gaze at 90Hz
    Tobii 5 = 133Hz – non-interlaced gaze at 33Hz
    Dynavox PCeye5 – sample rate 133Hz, 33Hz [Data Rate]

    Can you explain the distinction of “interlaced and non-interlaced gaze, and sample and data” in this context?

    When a Tobii EyeTracker 5 is being used for computer control, is it using interlaced gaze or…?
