TED stands for technology, engineering and design. It describes itself as “a small nonprofit devoted to Ideas Worth Spreading.” The means by which the foundation spreads the ideas are conferences in various parts of the world, videos of the presentations to those conferences and an annual TES prize.
Some of these presentations are grouped into themes and one of my favourite themes is the Tales of Invention theme. One of the most exciting presentations is Tan Le’s “A Headset that reads your brainwaves”. Tan Le demonstrates a new computer interface that quite literally reads the user’s mind.
