   Woow, that was a long discussion for a peculiar observation. To be honest I didn't clearly understand what the observation was at the beginning, I did feel it was pointing some sort of incoherence in my reply although I didn't kno

   Thanks for sharing. We have heard this too, in fact many visually impaired I've talked to are skeptical initially. Can't blame them since after many attempts to develop an Electronic Travel Aids (ETA) there was not a good product

    Sure, main difference from previous products are: - Form factor: prior devices couldn't get this small, most devices were heavy, obtrusive (mostly hand held), noisy and not precise (haptic actuators weren't miniaturized and optimi
