It's so easy to stare at the screen for too long and forget to blink! So comes this blink detection. But it can only detect and count blinks for now. A reminder will follow if the blink detection engine becomes more efficient. (The CPU burns while it runs!)

All honor goes to Affectiva’s Emotion-as-a-Service API. They do all the effort to recognize facial landmarks and derive measurements of facial features.

Most of the code (including Get Started below) are from Udacity's AIND-CV-Mimic project. The only tweak is to count blinks based on eyeClosure measurement and show the measurement history with ECharts.

Two ways to start:

1. Demo page

2. Run locally:

In order to access the webcam stream, modern browsers require you to serve your web app over HTTPS. To run locally, you will need to general an SSL certificate (this is a one-time step):

• Open a terminal or command-prompt, and ensure you are inside the blink-detection-js directory.
• Run the following shell script: generate-pemfile.sh

This creates an SSL certificate file named my-ssl-cert.pem that is used to serve over https.

Now you can launch the server using:

python serve.py

Note: The serve.py script uses Python 3.
