We are developing an AR-assisted maintenance tool for factory workers using HoloLens. My concern is the "Distraction Factor" and the privacy of the data being recorded by the headset cameras. What protocols should be in place to protect worker privacy and ensure they don't walk into hazards?

Safety must be hardcoded. We implemented "Peripheral Vision Passthrough" where the AR overlays automatically dim or disappear if the user’s walking speed exceeds a certain threshold, or if the headset detects moving machinery nearby. Regarding privacy, you need a strict "Edge Processing" policy. Ensure that the video feed used for spatial mapping is processed locally on the device and never uploaded to the cloud. Only metadata—like "Machine Part A Identified"—should be transmitted to your servers. This keeps you compliant with most labor union privacy requirements and standard GDPR protocols.
Deborah, edge processing is great for privacy, but does it limit the collaborative features? If a remote expert needs to see exactly what the technician is seeing to help with a repair, don't you have to stream that video feed? How do you secure that stream against interception?
We found that "UI Fatigue" is a real safety risk. Keep the AR HUD (Heads-Up Display) extremely minimal. Only show the information the worker needs for the current step of the process.
Minimalist UI is key. We actually used a "Voice-First" approach for our latest project, so the worker only sees a visual overlay when they specifically ask for it.
Kevin, for remote assistance, we use End-to-End Encryption (E2EE) and "Just-in-Time" access. The camera feed is only active during the specific support call and requires a two-factor authentication from both the tech and the expert. We also log every second of the stream for auditing purposes, so there’s a clear record of what was viewed and by whom.
