Disney researchers developing LED light communication technology

Typically, smart devices need to rely on Bluetooth or WiFi networks for communication. The problem is that WiFi networks are not always available, and Bluetooth consumes batteries quickly. These facts have enabled Disney researchers to find new ways to get devices to communicate with each other through led lights . As you might imagine, Disney researchers first communicated with built-in LED lights . LED built-in photodiodes can not only illuminate but also detect light.

Disney claims that this technology is a visible light communication system. Products originally used in this technology include toy cars, which can be activated automatically when approaching the light source. Another example is the little girl's clothes, built-in to activate the flashing LED lights, when the light bar is close, the LED lights on the clothes begin to flash.

However, the technology has other potential uses, such as an LED adapter connected to a smartphone or tablet that can receive LED light signals that are invisible to the naked eye, which will allow the store to send notification messages to the smartphone or tablet of the incoming customer. , more efficient than the current NFC Beam.
