Gazepoint GP3 with Opengaze very long start up delays
Hi all,
I'm currently trying to get a Pygaze protocol (designed and working with Tobii) to work on a Gazepoint. However, the library is taking a long time to initialise. The initialisation of the device takes about 1 minute, then preparing calibration another 1-2 minutes (and often fails, possibly due to hitting the limiter on a while loop).
Before I go digging around the library, is this behaviour expected?
Cheers, Matt

Hi Matt,
This is definitely not expected. What is causing the issue though, I have no idea.
Good luck digging!

Hi Matt - I'm also having this same issue with a Gazepoint GP3. Any luck figuring it out?

Hi Both of you,
While I still don't know what is going on and don't have an eye tracker available to try it out, here is what you can try to narrow down the problem. If you start Opensesame in debug mode, you get a lot of procedural information on the console, and check find out and which stage in the initialization or the calibration the delay happens.
Alternatively you can put print statements in the source code to get information about where the delay occurs. Once you know, it will be easier to think about solutions.
hope this helps,
Eduard
Hi @mattm , @sarah_s , and @eduard ,
Until recently, the implementation of GazePoint support in PyGaze was very poor, but this has been improved a lot. Can you try updating to the latest version of OpenSesame (3.3.12 at the time of writing) and see if this improves things? There may still be other issues though, so if you encounter any bugs with using the GazePoint, please report them here or on GitHub!
