Properties ¶

Name	Description	Constraints	Type	On runtime change
Settings
Joystick Device	Defines the joystick device	Design Time..	String
X Axis	Defines a joystick axis for the horizonal movements	Design Time..	Int32
Y Axis	Defines a joystick axis for the vertical movements	Design Time..	Int32
Tracking Mode	Defines the tracking mode, which controls how changes of the joystick axes affect the tracking position	Normal..	Int32
Calibration
Run Calibration	Open a calibration window	Design Time..	Boolean
Relative Speed Factor	Defines a speed factor for delta changes in the relative tracking mode	Normal..	Double
Relative Delta Threshold	Defines the minimal delta threshold for the stick angle in the relative tracking mode	Normal..	Double
Gain X		Normal..	Double
Gain Y		Normal..	Double
Offset X		Normal..	Double
Offset Y		Normal..	Double
Tracker Samples
Newest Samples	Returns an array of the most recent tracker samples. The array is updated every Control Loop cycle.	Status..	clPoin..
Newest Sample	Returns the newest tracker sample. The sample is updated every Control Loop cycle.	Status..	clPoint
Runtime
Radar Point	Returns the newest tracking position. In order to reset the tracking position in the relative mode, you can assign a new point to this property.	Normal..	clPoint
Filters
Smoothing Ratio	Defines a ratio for the fast FIR smoothing filter, which is applied to the gaze tracking within EventIDE. The filter convolves every new tracking position with the previous ones. The property value defines a tap weight for the previous data, such that the convolution looks like: X=(Xn*(1-Ratio)+Xn-1*Ratio)/2. The value has to be positive and less than 1 (0 means no filtering).	Normal..	Double
Logging
Log Folder	Opens the dialog for selecting a local folder that will hold all tracking logs	Runtime Command..	String
Open Log Designer	Opens a designer window where the log format can be defined.	Design Time..	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
Control
Is Enabled	If set to false the element is completely omitted when the experiment is run	Design Time..	Boolean
Title	Title of the element	Design Time..	String
