Lower fixation threshold / turn off stabilized animation?

All development related discussions that does not concern a specific programming language. For example, JSON data format, server communication etc.

Lower fixation threshold / turn off stabilized animation?

Postby mathieujofis » 24 Sep 2014, 20:45

Fixations seem to have a high threshold, and for a research project I need the threshold to be lower, is there any way to do this? Or at the very least, I would like to get rid of the stabilized interpolated animation of the gaze cursor (which I believe is controlled by whether a fixation occurred or not). For instance, if I look at items that are close to each other (such as text), the cursor sort of floats around, but if I look a far distance on the screen it will jump. Is there a way to make it always jump? I don't want the interpolated cursor data.

Thanks!

At the moment we have no plans to provide user-configurable options for the built in fixation detection algorithm. In general, it will improve over time as we perfect it.

For a research project I think it would be ideal to connect over the API to fetch the raw data and implement a custom fixation detection/smoothing function (you can find some source code online) That way you can tune it to your preference and have full control of all the variables.
