Yuyang D&U, Museum Curator App 'Li-on' and AR Game 'Starlight Tree' Development
Using OCC technology to receive relevant data when LED light is captured by the camera

An app utilizing Li-fi has been released.

The Lion app, introduced by Yuyang D&U, shows related data when standing in front of an exhibit in a museum. It uses OCC (Optical Camera Communications) technology, which receives data when LED light comes on within the screen.

The company also collaborated with game development specialist Purple Ocean to present the AR game 'Starlight Tree' that reflects LEDs. Just like Pokestops and gyms in 'Pokemon Go', plants in the game grow quickly wherever there are LEDs.

The current data loading speed varies depending on the performance of the mobile phone. The mobile phone that was re-enacted on site took about 3 seconds for the camera to recognize light, load the data, and turn to the page.

Up to now, Li-Fi technology has been mainly focused on location-based services. One module is mounted on one LED panel. So, it is also possible to control the lighting of each LED panel.

A representative of Yuyang D&U said, “The initial research and development was aimed at implementing Li-Fi with general lighting, but now Li-Fi can be used by replacing the lighting with dedicated lighting equipped with Li-Fi modules. The technology has not yet been fully completed for commercialization, as it has only been implemented in specific areas such as laboratories and marts.”

In particular, when Li-Fi is commercialized, it can be used in hospitals where Wi-Fi communication is restricted to prevent malfunctions in medical devices, smart factories where a mix of IoT devices is expected, and large parking lots where location-based services are emphasized.

Yuyang D&U started with ETRI's Li-Fi technology transfer. It has now launched an app with transmission/reception board integration and service development, and has stated that its ultimate goal is 'Li-Fi communication.'
