Hospitals can use touch-screen all-in-one machines to display drug and surgical fee standards, patient hospitalization, examination and other procedures, distribution maps of hospital departments, introductions to the hospital and doctors in each department, a list of doctors in each department who are available for consultation on the day, introductions to specially invited experts who are available for consultation in the hospital, and introductions to new hospital services. Cinemas can use touch-screen all-in-one machines to quickly promote films, allowing audiences to learn about film information as soon as possible.
