More than one eye tracker device on Mac OS X

[carlos.gomes]

Hi,

I just found an issue on Mac OS trying to connect more than one tracking device.
When I use the parameter 'device=number' and put a different number than 0 it gives an error:
'ERR: User-config device is not present in system!'.

I tried the same experiment on a Windows machine and it works fine. I can set up one of the eye trackers using 'device=0' and the other one using 'device=1'.

I am currently working on Mac OS X 10.9.4 and using the SDK TheEyeTribeSDK_OSX_0.9.41.

I am posting also the whole log:

Thanks

Thanks for posting, I've created a bug-report so that our developers can take a look at it. If we're lucky it's a simple fix and it will go out with the next update. Our main focus is to fixing the jitter-issue some experience on OSX first.

I tested it against the recently released SDK 0.9.46. Unfortunately, it is still not fixed yet. I understand there are different priorities. However, it will be nice if people from EyeTribe could shed some light on when this issue will be addressed.

Your efforts are really appreciated.

Hi Monchu,

Correct, multi-device connectivity has not been addressed with 0.9.46.
The dev-team are aware of the issue and will address it time allowing, Next release aims at adding support for OSX Yosemite which is becoming increasingly common.
