The system detects emotional states using tone, speech rate, and other voice characteristics. ## How It Works The AI records users' conversations through devices like smart glasses, phones, or smart speakers. The recorded audio is processed for emotional analysis and logged with timestamps, helping to understand users' emotional patterns. ## Enriching with Biometric Data The system analyzes not only voice but also eye movements and biometric data. Metrics like pupil size and blink rate are used to detect emotions such as stress or sadness. ## Amazon's Similar Initiative Amazon introduced a similar feature with its Halo wearable in 2020. However, the feature was removed in 2023 due to privacy concerns. Meta's system collects more comprehensive data than Amazon's. ## Regulations and Ethical Concerns The EU's AI Act, effective from 2025, bans AI that performs emotional analysis in workplaces and schools. However, consumer tools are exempt. Meta's system could face such regulations. ## Future Implications Meta's technology offers personalized experiences but also raises privacy and ethical issues. The system's implementation could increase users' concerns about data security. ## Sources covering this story - https://thehackernews.com/2026/07/meta-files-patent-for-ai-that-can.html — --- _Summary written by Brifing from the original reporting.
