1.3 million people suffered from blindness in America in 2010 and that number is expected to triple by 2050. Many blind people click with their tongue as a means of soliciting echos from the environment which are processed by their brain and used to locate objects and navigate. While it has been shown to be extremely effective, the technique is difficult to master. The optimal clicking frequency is a critical part of the technique and is a challenge for many to learn. Sonic Eyewear looks like a regular pair of sunglasses that automates the clicking process by generating the optimal frequency of clicks on-demand. It sends forward-looking directional clicks when the user lightly taps her jaw to activate the signal. The technology leverages the power of the human brain to perform echolocation, which competitors have failed to do.
