Here is something interesting (A face reader with emotion detection). Once you click the link https://126.96.36.199/emo/ in chrome, you would see a comedy video of stand up comedian. Browser would ask you to allow video cameras and safe permission. Just allow it and keep your face around 1 ft away from laptop.
Now when you will there is a face overlay on top of video which mimics your facial emotions / reactions. There would be graph under which will show datapoint about happy, sad, angry, suprise etc.
Follow below steps and enjoy :
1. Open on Chrome
2. Use laptop
3. Allow access to video cam
4. Keep laptop at 1 ft distance
