As someone who is blind this sounds too good to be true and I will not be dropping $2500 on what will most likely be a complete waste. If it can help me find street crossings, tell me when a light changes, and pin point specific entrances in heavily built up areas like strip malls I would pay what they’re asking in a minute. What intrigues me about this is using bone conduction to provide the information. My blindness is caused by a significantly underdeveloped optic nerve so the current development in the area of having cameras directly providing visual input to the brain will not work for me. Even if this device is vaporware hopefully the use of bone conduction technology may lead to something more useful in the future beside Bluetooth earphones I can pair with my iPhone.
