If the active display is located below the measuring point on the eye tracker, for
example, in a projector setup, the value will be negative. Enter the value in the X
Configuration Tool with a “-” in front to signify it as a negative value.
6.9 Using a setup with side offset
If the Eye Tracker is not placed right in front of the screen with the axis horizontally
aligned, an offset can be entered in the X Configuration Tool (called Side offset).
In this case check the
Use Side Offset
check box and enter the side offset from the
center of the active display to the center of the eye tracker, enter a negative value if the
eye tracker is located to the left of the center as seen from the front.
6.10 Using a setup with angle offset
The eye tracker should be placed parallel with the display or tracked object. If this
is not the case you should check the
Use Rotation check box and enter the angle
between the back of the eye tracker and the active display. If the eye tracker is rotated
clockwise, enter a negative angle.
6.11 Saving the configuration
When using different setups it is useful to save the different configurations locally on
your computer. This gives you the possibility to go back and reuse the configuration
for the specific setup. The file can also be used as a local backup for your
configuration in case the settings need to be adjusted later.
Configurations can be saved and loaded in the Configuration tool.
Click
Save To File to save the configuration as an .xcfg file locally on your computer.
Click Load from File to load a saved .xcfg configuration.
To start using the configuration entered in the tool you must click Save to Eyetracker .
The parameters will then be sent to the eye tracker and the eye tracker will
immediately be properly configured. When any parameter in the tool is changed the
button must be pressed again for the eye tracker to get the new settings.
