This article explains how multimodal UX allows users to interact with digital products through various input methods like voice, touch, and gesture. It highlights the importance of designing for real human behavior and improving accessibility and user satisfaction by offering flexible interaction options.

The article discusses the development of Odyssey-2 Pro, a world simulator that predicts how the world evolves using vast amounts of video and interaction data instead of pre-defined rules. This approach allows the model to learn complex structures like physics and human behavior, enabling more interactive and stateful simulations.
