algoMind transforms an everyday supplement dispenser into an on-device AI mental health coach that detects early signs of depression and cognitive decline, including dementia and mild cognitive impairment (MCI). On the dispenser's touchscreen tablet, users report how they feel that day, and the device instantly blends a personalized supplement combination. In that brief moment—as the camera reads the face, a voice conversation guides the blend, and fingers tap the screen—algoMind captures physical and psychological state from facial expressions, mental state from the voice, and cognitive state from touch patterns. It combines these signals with health checkup records, prescription data, and everyday usage patterns to infer the user's overall mental state and identify early signals of depression and MCI. All analysis runs in a secure on-device environment where personal data never leaves the device; algoMind then adjusts supplement combinations and connects users to cognitive behavioral therapy through its mobile app.
