So far we’ve been doing our own fixation detection (we are aware of the fixation data available via the EyeX SDK, but we don’t use it widely). We haven’t evaluated yet whether that still works with the data we get out of the StreamEngine. If no, we will probably need fixation data from the stream engine, yes.
But what I’m looking for is a way to configure the level of filtering/smoothing used. These graphs contain two seconds of gaze data simultaneously collected via ExeY SDK (TX_GAZEPOINTDATAPARAMS: {TX_GAZEPOINTDATAMODE_LIGHTLYFILTERED}) and StreamEngine for comparison. The TSE data is actually really nice for most of our usecases (and may save us CPU we previously spent on smoothing), but for some we may need that extra bit of responsiveness currently only available to us through the EyeX SDK’s API (specifically this bit).
