‘Paper-to-digital’ electronic medical records. Smartphone screenshots show how paper-based templates for clinical documentation, in this example for hypertension (HTN) screening by a community health worker, are combined with a browser-based computer vision application that automatically recognises the filled circles seconds after taking an image of the template. The interface allows for visual confirmation of accuracy and quick editing (if needed), followed by sync-ing of data to a cloud server.
