getEyeTracker(id).stop() (since PennController 1.8)
Stops tracking which element is being looked at.
The EyeTracker element will stop collecting and sending data points to your PHP script after stop is executed.
Example:
[js highlight=”11″ try=”data”]newTrial( newButton(“Start”).print().wait(newEyeTracker().test.ready()) )
newTrial(
newEyeTracker(“tracker”).calibrate(70)
,
newText(“Left”).css(“padding”,”20vw”).print(“20vw”, “40vh”),
newText(“Right”).css(“padding”,”20vw”).print(“60vw”, “40vh”)
,
getEyeTracker(“tracker”).add( getText(“Left”) , getText(“Right”) ).showFeedback().start()
,
newTimer(1000).callback( getEyeTracker(“tracker”).stop() ).start()
,
newSelector().add( getText(“Left”) , getText(“Right”) ).wait()
)[/js]
Will stop tracking looks after 1 second.
