At Meta, Dan is an industrial design and hardware prototyping specialist focused on wearables, input devices, and AR/VR hardware user experience. Dan turns early, ambiguous product questions into testable prototypes and clear design recommendations, helping teams converge on interaction systems that are comfortable, reliable, and scalable.

What Dan does

• Defines next-generation wearable input experiences: Dan explores interaction models for compact devices (e.g., touch, squeeze, button/“buttonless” concepts), mapping them to real user needs like media control, calling, voice/assistant activation, privacy modes, and device state control.
• Builds rapid hardware + software prototypes to inform decisions: Dan creates end-to-end prototypes that combine industrial design intent with sensing, firmware/software behaviors, and user feedback, then documents trade-offs and recommended directions.
• Improves reliability of real-world interactions: Dan develops strategies to reduce accidental activations, improve discoverability, and ensure inputs work across varied users and environments (e.g., different skin conditions, outdoor lighting, and daily wear scenarios).
• Develops wearing/on-body detection concepts: Dan prototypes sensing approaches that help devices understand when they are being worn or removed, enabling more seamless behaviors like auto-sleep/wake and context-appropriate feedback.
• Designs accessory and charging experiences: Dan prototypes case/accessory interactions and feedback systems—such as lid/open detection concepts and clear status feedback—to make setup, charging, and everyday use more intuitive.
• Designs feedback systems (light + audio + haptics): Dan evaluates and prototypes multimodal feedback approaches so users can understand device status and actions without needing a screen.
• Creates reusable prototyping tools and raises team velocity: Dan builds flexible prototyping rigs and reusable foundations that allow faster iteration across multiple concept directions, and shares documentation and demo assets with cross-functional partners.
• Collaborates and mentors: Dan supports cross-functional teams through office hours, hands-on demos, and mentorship, helping align design, engineering, and UX on practical, high-quality interaction solutions.

Areas of emphasis

• Wearable input architecture (how a device should be controlled)
• Human factors / ergonomics for small-form-factor interactions
• Sensor + interaction prototyping (touch, proximity, motion, etc.)
• User feedback design (light/audio/haptics)
• Rapid iteration and decision support through prototypes and documentation
