Maintain the visual consistency of hospital indicators, and uniformly use the main colors and brand styles of the hospital to establish a unified image. Use large fonts and easy-to-understand text to ensure that the information of the signs can be understood quickly and avoid confusion. If the hospital has patients in different languages, consider providing multilingual information on the indicators. For important areas, such as emergency departments, stairs, elevators, etc., use clear signs to make them easy to identify. Use arrows to indicate the direction to help people find the correct direction of travel, especially in complex hospital layout. Add symbols and icons to hospital indicators to improve visual recognition, especially for people of different languages and cultures.
