The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our team at Meta Reality Labs Research built the Aria device, an egocentric, multi-modal data recording and streaming device with the goal to foster and accelerate research in this area.

C2weakest assumption

That the described hardware configuration, sensor suite, and software tools will prove sufficient and accessible enough for the broader research community to meaningfully advance egocentric multi-modal AI.

C3one line summary

Project Aria presents a new wearable egocentric multi-modal recording device and software tools to accelerate AI research for augmented reality applications.
