Fujitsu Laboratories today announced the development of a technology that can embed ID data in light cast by LEDs or other light sources onto objects, and also recover this ID data from objects that have been lit in this way. By embedding data in light in a way that it is not detectable to the naked eye, an object that has been illuminated can convey data to a smartphone or other smart device. With previous technologies, data could only be conveyed to a user’s area, but with this technology, data can be conveyed at the level of an individual object. To capture the data, a user only needs to point a camera at the object. This technology enables products in a store, works of art, people, buildings and a variety of other objects to be the source of data transmission.
Color LEDs combine the three lights of red, green, and blue (RGB) to produce a range of colors. By modulating the intensity of the light emitted by each of the three component colors along the time axis, ID data can be embedded in the light cast onto an object, even with very small variations. Fujitsu Laboratories is currently conducting tests to assess the technology with a range of installation environments, and is working to improve its accuracy with the goal of commercial implementation during fiscal 2015.This technology will be exhibited at Fujitsu Forum 2014, running November 19-20 in Munich, Germany.
