Realtime emotion tracking in JavaScript

In plain words

Realtime emotion tracking in JavaScript is a JavaScript library that detects and analyzes human emotions from video or images in real time. Developed by Affectiva, it enables developers to integrate emotion recognition into web applications. The tool identifies facial expressions and translates them into emotional states, making it useful for applications in user research, customer feedback analysis, and interactive experiences. It processes data directly in the browser without requiring external servers.
