ID-embedded LED Lighting Technology for Providing Object-related Information

The spread of smart devices and the expansion of the communications environment for accessing the Internet have made it possible for users to obtain information whenever they want and wherever they are. It is now commonplace for them to search the Internet and obtain relevant information for a certain object on the spot. However, the extraordinary volume of information on the Internet sometimes makes it difficult for users to find the information or service they want immediately. To make it easier to find object-related information on the Internet, Fujitsu Laboratories has developed a technology for embedding ID information in light. Casting of such light on an object and the recovery of the ID from the reflected light using image processing technology enables a user to easily access relevant information by capturing an image of the object with the camera in a smart device. Service providers can use this technology to increase communication channels with end users and expand the services they provide. This paper presents an outline of this technology and explains its usage and potential applications.
