LEGO has unveiled a new 'smart brick' that can detect how it's being played with and react accordingly. This brick, developed in partnership with Wired, uses a combination of sensors and AI to understand building techniques and provide feedback. It's designed to inspire creativity and learning through play, offering features like pose detection, color recognition, and shape identification. The brick is part of LEGO's ongoing efforts to integrate technology into its building system, aiming to create more interactive and educational experiences.
