Optis has been involved in advanced optical simulation for the past 25 years and has recently invested in VR for virtual prototyping. Its latest HIM built for human ergonomics evaluation in combination with advanced, real-time, physics-based rendering enables precise environment reproduction for appropriate prototyping or training. We'll present the latest integration for assembly line training with HTC Vive and feedback powered by NVIDIA PhysX. Companies such as Tesla Motors and Bentley are the proud early adopters of this solution. We'll demonstrate our software and show customer use cases and their data to explain how to improve the VR experience with haptics and audio simulation in the future.
