Proofit 1D is a system that verifies whether the type and amount of medicine a pharmacist has put together for a patient is correct. It takes a photograph of the pharmaceutical packages and displays their fronts and backs side by side in a tiled screen layout. For better organisation, the medicine units are listed horizontally while the packaging units are listed vertically. Any object that proves difficult to automatically categorise is displayed at the top of the screen, so that users can immediately see whether it is something that requires further attention. In addition, items with incorrect dosages are marked in a yellow signal colour.
