[Solved] Is it possible to retrieve the results of calibration

[pilipala]

Hi,

I am using Tobii REX as an input device in a HCI experiment.I need
to record the results of calibration, such as accuracy, for post-
analysis.

I am using EyeX SDK for C/C++ 1.7 with EyeX interaction 2.1.1.3125.
There seemed to be no information in the developer’s guide as well
as the samples.

anyone knows? @Jenny

Thanks a lot!

Hi @ pilipapla119,

within the Tobii Tech SDK, the calibration processes are taken care of by the Tobii Interaction and the specifics of the calibration results are not publicly exposed.

For these purposes we provide the Tobii Pro range of eye trackers, targeted for research where the full range of calibration and eye tracking metrics are available. Apologies for the inconvenience.

That being said, there have been a number of comprehensive studies of eye tracking accuracy using EyeX (I could not find one for REX) which you can find @ http://link.springer.com/article/10.3758/s13428-016-0762-9
Perhaps this information will be of use.

Thanks! Hope the new SDK for Tobii Pro TX300　released ASAP. @grant-rogers
