Neckium is a Chrome extension that enables users to browse using head movements while promoting correct sitting posture. By leveraging Tensorflow.js and the web camera, Neckium can detect head movements to control browser functions. For instance, users can scroll pages vertically and switch tabs horizontally with simple head gestures. Additionally, Neckium provides alerts to users if their sitting posture is incorrect or if they have been sitting for an extended period.

This innovative tool not only enhances browsing convenience but also emphasizes the importance of maintaining a healthy sitting position while using the computer, ultimately promoting better ergonomics for users.
