Apple Inc. is working on technology to help diagnose depression and cognitive decline, aiming for tools that could expand the scope of its burgeoning health portfolio, according to people familiar with the matter and documents reviewed by The Wall Street Journal.
Using an array of sensor data that includes mobility, physical activity, sleep patterns, typing behavior and more, researchers hope they can tease out digital signals associated with the target conditions so that algorithms can be created to detect them reliably, the people said. Apple hopes that would become the basis for unique features for its devices, according to the people and documents.
