Professor Harald Haas received a standing ovation at TED Global 2011. He successfully demonstrated visible light communication in action by using an LED light bulb in an anglepoise lamp. This transmitted HD video which was displayed on a large screen behind him. He cut the beam with his hand and the video froze until his hand was removed to prove that the data was being transmitted live from the light bulb.
Afterwards he said “This was very exciting because it was the first time we have shown this publicly to a large audience. They seemed to genuinely understand the significance of what we have developed.”
Well done Harald on a really professional demonstration of VLC in action.
