Infrared Beacon

A device that transmits identification signals using infrared light, used in indoor navigation and wayfinding systems to help locate users within buildings. When a user's receiver detects the beacon's signal, the system can determine the user's position relative to known locations. Infrared beacons are inexpensive and highly accurate but typically require line-of-sight communication. They are used in assistive technology systems like Talking Signs to provide location-specific information to people who are blind or have low vision.
