VI-grade, a provider of automotive simulation technologies, has launched the Compact HMI Simulator, an immersive tool designed to enhance the development, evaluation and testing of Human-Machine Interface (HMI) systems in vehicle interiors. The simulator has already been adopted by two automotive manufacturers.
The Compact HMI Simulator combines a flexible interior simulator with real-time driving simulation, thus integrating accurate vehicle dynamics, AI-powered traffic scenarios, diverse driving conditions, and the ability to incorporate virtually any hardware or software in the loop (HIL/SIL). This comprehensive approach enables engineers to refine HMI designs in realistic driving environments without relying on static mockups or costly physical prototypes.
The system features a modular, reconfigurable interior buck that accommodates various seating, steering, dashboard and display configurations, allowing designers to prototype and evaluate multiple HMI layouts without requiring separate physical mockups. With automated adjustments, it can replicate seating, steering and pedal conditions for many vehicle types, from sports cars to SUVs, within a single setup.
The system also includes the full capabilities of a real-time driving simulator, supporting XIL testing and validation. It facilitates human-in-the-loop testing, allowing engineers to assess HMI usability and driver interaction under realistic driving conditions.
The Compact HMI Simulator also provides direct interaction with digital instrument clusters, infotainment touchscreens, and voice controls in a controlled yet immersive environment. The system also supports ADAS and driver monitoring research, facilitating studies on driver distraction, workload, and interaction with automation features.
“HMI design is a critical aspect of modern vehicle development, directly impacting user experience, safety, and driver interaction with advanced driver-assistance systems”, stated Guido Bairati, managing director of VI-grade. “However, traditional evaluation methods rely on static mockups or costly physical prototypes, which are time-intensive and inflexible. Our new Compact HMI Simulator overcomes these limitations by providing a configurable and highly immersive simulation environment that allows engineers to experience and refine HMI designs in real-time driving scenarios.”
