Meta has unveiled the next generation of its Project Aria augmented reality glasses, dubbed Aria Gen 2. The update brings significant enhancements to the platform, including a revised sensor suite and custom silicon. This upgrade includes the addition of a photoplethysmography (PPG) sensor for measuring vital signs, indicating a shift towards more comprehensive and health-related applications. While details on specific use cases are scarce, the implications of this development suggest a potential expansion into fields such as medical research, fitness tracking, or other areas where augmented reality can provide novel insights.
