I am trying to program our Tobii X120 using the low-level SDK. I tried last year, ran into some problems, and stopped. Now I'm trying again, and I have a couple of questions. 1. I'm trying to do a calibration. I call:- Tet_CalibClear()- Tet_CalibAddPoint(x, y, n_samples, 0, 0, 0) for every point- Tet_CalibCalculateAndSet() When I call ...

Select the number of calibration points your team uses when calibrating test participants.[Poll]

When calibrating participants to our T120 monitor, we have seen instances when one of the calibration points on the calibration plot screen is not marked. When this occurs, we select the unmarked point and try to recalibrate but continue to receive the same unmarked calibration point.  Sometimes we try for a third time and receive the same ...

pedroarellano:I have troubles with the calibration in our tobii T120 eye tracker.When I create a project or when I use an existing one, the whole process isnormal until I have to calibrate. The software tells me every time thatisn't ''Enough calibration data'', so the gaze are very imprecise in thereplays and in visualizations.What can I ...

The TETServer always uses the last loaded calibration when tracking, it cannot use two calibrations at the same time. If you calibrate in Tobii Studio, the same calibration will be used for any application communicating with the TETServer, until a new calibration is loaded. Did you turn off the fixation filter in Tobii Studio when replaying the ...

Thanks for your reply.  I am doing research in eye gaze interaction (EGI). Users select items using gaze in an application developed with Tobii SDK. I need to record my experiments for later analysis. If I calibrate the user in my application (via SDK methods), that calibration is going to be different from the one in Tobii Studio. The ...

sacampus:I need to ensure that my application and tobii studio are using the same calibration. Where do I find the calibration files for test users in my project?Tobii Studio stores all gaze, participant, AOI, web grouping and calibration data in a database which means that it unfortunately is not accessible to other applications.To be sure that ...
