Augmented Reality based interface for laser-cutting

with Anirudh Sharma and Nitesh Kadyan. 2015

Chalkaat AR laser cutter is the continuation of the project Clearcut started by Anirudh Sharma at the MIT Media Lab in the Fluid Interfaces Group. I joined Anirudh and Nitesh in 2015 and contributed in defining user interactions and usability, designing the comunication of the project and identifying business strategies and market appications.

Present day CNC/Laser-cutters have a indirect interface involving external computers. Chal-Kaat is a direct manipulation laser-cutter that’s aware of the strokes being drawn on the workpiece. It is a ‘computer-less’ UI for interacting with laser cutters, where the users can express themselves more directly by working directly ‘ on the workpiece’. The camera on top tracks the strokes. Different colored markers allow different commands to be executed. We built a laser cutter from ground up, with computer vision and mechanics to optimize for the interface.
