In plain words

3Gear Systems is a gesture recognition platform that enables developers to add hand gesture controls to applications. The San Francisco-based team has built the technology to detect and interpret hand movements as computer input. The software is designed for developers seeking to integrate gesture-based interaction into their applications as an alternative input method.

We started 3Gear Systems with the singular goal of creating a gesture recognition system that actually works. We've been disappointed by what's currently available, and felt that with our backgrounds , we could build something a lot better—something reliable enough and powerful enough to become a basic part of interacting with a computer. Since we founded the company in March 2012, we've stayed lean and 100% focused on solving the hard computer vision and human-computer interaction problems involved in building the world's best gesture recognition technology. What started as a project from one of our co-founder's PhD work at MIT , evolved into a system that used two Kinect cameras set…from threegearsystems.blogspot.com

    I'm sharing my project to control 3D models with voice commands and hand gestures: - use voice commands to change interaction mode (drag, rotate, scale, animate) - use hand gestures to control the 3D model - drag/drop to import other models (only GLTF format supported for now) Created using threejs, mediapipe, web speech API, rosebud AI, and Quaternius 3D models Githhub repo: https://github.com/collidingScopes/3d-model-playground Demo: https://xcancel.com/measure_plan/status/1929900748235550912 I'd love to get your feedback! Thank you
