mousetracker.callback
getMouseTracker(id).callback( command ) or getMouseTracker(id).callback( function ) Will run the PennController command(s) or javascript function passed as arguments whenever the mouse moves after and before have been called. If you pass a function, it will be receive two arguments when executed, corresponding to the current X and Y coordinates. Example: [js highlight=”9-15″ try=”true”]newButton(“Click then move …
mousetracker.stop
getMouseTracker(id).stop() Stops tracking the mouse cursor coordinates. Make sure to use this command to stop tracking and prevent your results file from growing too much. Example: [js highlight=”18″ try=”true”]newButton(“Start”) .print(“center at 50vw”, “center at 50vh”) .wait() .remove() , newMouseTracker(“mouse”).log().start() , newCanvas(“left”, “40vw”, “40vh”) .css(“background”,”red”) .print(“center at 25vw”,”center at 50vh”) , newCanvas(“right”, “40vw”, “40vh”) .css(“background”,”blue”) .print(“center …

mousetracker.start
getMouseTracker(id).start() Starts tracking the mouse cursor coordinates. The MouseTracker element will not collect any data points until start is executed and unless is called. Make sure to use to stop tracking and prevent your results file from growing too much.

Collecting eye-tracking data
Failing calibration with a score of 0? Upload this file to your project to overwrite the EyeTracker element (don’t mind the corresponding warning message in the Debug window) The EyeTracker element is supported by a limited set of browsers. For best results, your participants should use Chrome desktop or Firefox desktop. Even so, calibrating is …

eyetracker.showFeedback
getEyeTracker(id).showFeedback() (since PennController 1.8) Shows the red dot estimating your looks, which is hidden by default after calibration. 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”).hideFeedback() ).start() , newSelector().add( getText(“Left”) , getText(“Right”) ).wait() )[/js] Will still show the …
eyetracker.test.ready
getEyeTracker(id).test.ready() (since PennController 1.8) Tests whether the participant has granted webGazer access to their webcam, as required by the EyeTracker. Use this early in your experiment, and most usefully in the command of a Button to proceed only after access has been granted. Example: [js highlight=”3,4″ try=”true”]newButton(“Start”) .print() .wait( newEyeTracker().test.ready() .failure( newText(“Please grant access to …
