- Implemented core MR interactions using XR Interaction Toolkit.
- Built placement flow, color switching UI, and voice assistant features.
- Integrated Gemini-based STT/TTS pipeline for Q&A.
Engineering Impact & Measurable Outcomes
- Mercedes-Benz MR vehicle placement on Meta Quest 3
- Spatial UI menu & real-time car color customization
- Passthrough spatial surface anchoring
Genre & gameplay: The Mercedes-Benz MR Car Showcase is an interactive mixed reality experience that lets users spawn a full-scale car in their real space, walk around it, change visual trims and colors, and interact with it using floating UI panels and voice.
My contributions: Implemented core MR interactions using Unity XR Interaction Toolkit for both hand tracking and controllers on Meta Quest 3. Built the placement flow, color/trim switching UI, and object interaction behavior. Integrated a Gemini-based STT/TTS pipeline so users could ask questions and receive spoken answers inside the headset, including a custom audio path for playing responses. Collaborated with the team to keep performance and visual quality aligned with showroom expectations.
