Introduction

This Video player analyzes a JSON file containing coordinates and timestamps (the JSON data corresponds to the frames in a video track - this file will be built in advance using some eyetracker and eye tracking software) to present relevant pixels, according to time, on the screen using heatmap.js.

Motivation

• Understanding user's viewing/reading behavior (Eye tracking technology, EEG, Cursor behavior, etc.)

Requirements

• Create JSON with provided software (./tet/TETWinSamples.sln) - EyeTribe GitHub
• Note! You can generate your own json file from any eye tracker using this format (JSON example containing 2 coordinates)

{
 "data":[
	{
	 "x": 1008,
	 "y": 582,
	 "timeStamp" : "00:00:00.0030017",
	  "second" : "0"
	 },
	{
	 "x": 1008,
	 "y": 580,
	 "timeStamp" : "00:00:00.0230138",
	  "second" : "0"
	 },
	{}
]}

How to use it
