eyetracker.start

description

Starts tracking which element is being looked at.

syntax

getEyeTracker(ELEMENT_NAME).start()

notes

  • You should use add first to tell the eye tracker which elements are to be tracked.

  • The EyeTracker element will not collect any data points until start is executed. Use stop to stop tracking elements and sending data to your PHP script.


example(s)


@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").hideFeedback() ).start()
@    ,
@    newSelector().add( getText("Left") , getText("Right") ).wait()

  • Will start tracking looks to the Left and Right elements after they are printed.
