Name	Description	Constraints	Type	Upon Runtime Change
GLM Calibration
Run GLM Calibration	Runs the GLM calibration procedure, which calculates two pairs of linear coefficients for mapping of the tracker input into the screen coordinates. The calculated coefficients are automatically applied at runtime.	Designtime Command..	Boolean
Gain X	Defines the gain coefficient for the X axis in the GLM calibration model: X='GainX'*x+OffsetX		Double
Gain Y	Defines the gain coefficient for the Y axis in the GLM calibration model: Y=GainY*y+OffsetY		Double
Offset X	Defines the offset coefficient for the X axis in the GLM calibration model: X=GainX*x+OffsetX		Double
Offset Y	Defines the offset coefficient for the Y axis in the GLM calibration model: Y=GainY*y+OffsetY		Double
Drift Correction
Recalibrate Now	Runtime command that helps to correct drifts in tracking data.Correction is done by recalibration of the latest tracker position into a custom screen point defined by the 'Recalibration Point' property.nAs result, the offsets of the GLM calibration get adjusted (but not gains) to compensate a drift in further data.	Runtime Command..	Boolean
Recalibration Point	Defines the screen point to which the tracker position will be recalibrated on calling 'Recalibrate Now' action. The default auto value always denotes the screen center.	Normal..	clPoint
Logging
Log Folder	Opens the dialog for selecting a local folder that will hold all tracking logs	Designtime Command..	String
Open Log Designer	Opens a designer window where the log format can be defined.	Designtime Command..	Boolean
Is Logging	Defines whether logging is turn on/off. The value can be changed at any moment at runtime allowing selective logging during the relevant periods only.	Normal..	Boolean
User Field	Defines the custom user data that is added to every line in the log file. The property can be used for recording varying status information (e.g. trial number) together with the tracker data. The string value may contains multiple fields separated by delimiter.	Normal..	String	Once a string value is assigned, it is added to every new upcoming line in the log until a new assignment is made.
