Hands-Free Interaction: Eye Tracking and Voice Commands on HoloLens 2

Creating intuitive spatial computing applications requires moving beyond physical controllers and hand gestures. Designing for hands-free environments opens up powerful accessibility options and streamlined workflows for frontline workers and everyday users alike. This written course guides you through the foundational concepts and practical implementation of eye tracking and voice commands on HoloLens 2. You will transition from understanding spatial input theories to configuring fully responsive, gaze-aware, and speech-activated virtual objects. What you'll learn: - Understand foundational eye-tracking concepts and gaze-based selection mechanics - Configure voice commands and speech recognition subsystems for natural language input - Implement gaze-aware object behaviors that react when a user looks at them - Apply modern Mixed Reality Toolkit (MRTK) interaction profiles to streamline setup - Design accessible, hands-free user interfaces using best practices in spatial UX - Troubleshoot common calibration and environmental tracking challenges in mixed reality You will begin by learning core spatial computing terminology and configuration basics before moving into step-by-step implementation strategies. The text-based lessons then walk you through code structures and configuration settings to connect gaze and speech inputs to object actions. This course is designed for beginning developers, UX designers, and spatial computing enthusiasts. No prior experience with HoloLens development is required, though a basic familiarity with object-oriented programming concepts is helpful.
