Project Aria is a Meta project focused on first-person perspective research, aiming to advance augmented reality (AR) and artificial intelligence (AI) through innovative technologies. The project collects information from a user's perspective using devices such as the Aria Gen 2 glasses, providing support for machine perception and AR research. Its key advantages include innovative hardware design, rich open-source datasets and challenges, and close collaboration with global research partners. The project's background stems from Meta's long-term investment in future AR technology, aiming to drive industry progress through open research.
