IntelliGaze™ Installation & Service Manual Troubleshooting
If the camera is not shown as above run the tool reinstall driver which is located in the IntelliGaze
folder/driver.
10.1.3 'Measure the monitor before calibration error'
Definition
The system requires a proper monitor calibration before it can calibrate a subject. Changing the moni-
tor resolution or the camera position with respect to the monitor invalidates the monitor
calibration.
Solution
Launch the tool MonitorCalibration and make sure that the physical screen dimensions and the moni-
tor resolution match your setup.
10.1.4 Dwell click is never triggered
Problem
Although the subject is properly fixating on a point, the dwell cursor never comes to an end and resets
itself.
Analysis 1
Some USB devices like memory sticks or external hard-disks allocate too many shared USB
resources. The CAM30 data transfer might be interrupted by these devices resulting in an irregular
video transfer which finally disturbs the eye event detection. Remove external memory sticks.
Solution 1
In general, other USB devices like web cams, speakers, headsets are not a problem.
Please select hardware combinations carefully and, if problems occur, consider moving other devices
to a different USB port.
Analysis 2
The data is too noisy for proper fixations to be detected, or the detection parameters are miss-config-
ured.
Solution 2 – Software setting
The fixation dispersion is set to a value which prevents proper fixation detection. Increase this value.
10.1.5 IntelliGaze crashed
Definition
The IntelliGaze software crashes.
Solution
IntelliGaze has a build in crash recovery restarting the software after a crash to be able to control the
pc. However to understand what the reasons of the crash are and to find a solution for that it's helpful
to inspect the crash log files. They can be found in the folder
