Depression is a silent killer and a serious threat to mental health, and people often try to hide their inner turmoil. It is important to detect the early symptoms of depression so that it can be treated timely. A study shows that this can actually be possible with the use of smartphones. Researchers at Stevens Institute of Technology have envisioned two smartphone apps that could soon help you diagnose depression by analyzing your face and eyes.

Researchers have developed two AI-powered applications to identify symptoms of depression. PupilSense detects depression by changes in the eyes. Previous research has also documented an association of the pupillary reflex with depression episodes. The app works by capturing 10-second snapshots of your eyes when you open or use your phone. The study involved 25 volunteers over four weeks and evaluated approximately 16,000 interactions with the app over four weeks. Initial results of the app were encouraging as the app accurately identified depression episodes in 76% of cases. It outperforms existing smartphone-based systems. This is unprecedented because this method of testing does not require any special equipment or instruments.
