What do you mean you have blind vision?
At one year old, Daniel was diagnosed with a cancer called retinoblastoma, which destroys the retinas. At age 14 his eyes were removed, in order to save his life. Now 46 Daniel uses 'echolocation' -- sending sound waves from his tongue that bounce off physical objects and allows him to gauge his whereabouts -- to help him to navigate the world in remarkable ways. Echolocation is how bats and beluga whales can 'see' and he has dedicated himself to teaching the technique to a new generation of blind children in America and throughout the world. Many blind children intuitively use clicks to orient themselves but this behaviour is often discouraged by mainstream blind organisations and carers. Here, Daniel will explain why 'that tongue click was everything to me".

About TEDx, x = independently organized event
In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)
