What is Neckium?
Neckium utilizes the local webcam and TensorFlow.js models to precisely detect subtle vertical and horizontal head movements: vertical motion controls webpage scrolling, while horizontal movement switches browser tabs. At the same time, it continuously analyzes sitting posture, proactively displaying desktop notifications when it detects improper posture or extended periods of inactivity (such as remaining still for too long), reminding users to adjust—balancing interaction efficiency with health protection.
