Questions about Eye Tribe: View track box in OpenSesame? Suppress calibration feedback?

TomArmstrong

Hi all,

1. I was wondering if it is possible to view Eye Tribe's track box (from the UI--the eyes that range from green to red) within OpenSesame? We try to make sure that there is no need for adjustment after the experiment begins, but it would be great if you could have some information analogous to the eye image that you get with other eye trackers. Or would it be possible to open the Eye Tribe UI while running an experiment in OpenSesame?

2. Also, can you suppress the calibration feedback (i.e., the dots with the error visualized)? We are trying to play down the fact that we are eye tracking. Finally, is it possible to program the experiment so that, rather than receiving the calibration feedback and the option to proceed or repeat calibration, the program instead automatically proceeds or repeats depending on some error threshold?

Thanks for any advice!

Hi Tom,

As it currently stands, neither of those things are possible. They are technically possible, as the EyeTribe does provide information on where the pupils are in the eye image (which you could use to construct the eye box from the UI). The calibration feedback is there only to help you, so you could take it out of the source code without performance issues.

Cheers,
Edwin
