**Review of !WebGazer.js** On the original website of this project there are three life demos that you can try. I will try and explain my observations for the three of them below. ** Ex.1** **!WebGazer.js on an Empty Webpage with calibration** Steps in this simple example: [[Image(wg1.png)]] **Step 1. Reading the instructions before calibrating the system** [[Image(wg2.png,50%)]] **Step 2. Turning on the webcam as it recognizes my face before calibrating** [[Image(wg4.png,50%)]] **Step 3.Calibrating the system by clicking on the nine red points five times each while looking at them** [[Image(wg5.png,50%)]] **Step 4. Calculating the accuracy of the predictions** [[Image(wg6.png,30%)]] **Step 5. Results of the accuracy of the predictions** [[Image(wg7.png)]] **Step 6. After the calibration is done we can control the cursor with our eyes. As you can see from the picture I am looking at the top of the screen, where the cursor is and the mask on the face shows** **Ex.2 Ball Collision Game**
