I still feel that a sun glasses or hat attachment plus a belt or around ribs strap type attachment working in consort, if done right, with weatherproofing, rugged construction, light weight, high user customizability, surreptitious alerts, decent battery life, attainable pricepoint, ETC could be worth something, maybe. But honestly I’m not sure if the tech is their yet to be worth it unless you’re deafblind, and even that’s not a for sure thing. Maybe someday, but I don’t think smart canes or wrist wearables are going to be viable in this decade. To me, good training solves 95% of these problems anyway, but to be fair, that is much more expensive to do. Don’t let perfect be the enemy of good and all that…
P.S. I’m not usually that guy, but honestly sighted people can keep their negative opinions about your cane to them selves IMO, they don’t use one every day. Besides, we do use other tech, like GPS, OCR, and live assistance apps to help us, and those of us who can also use echo location, along with other context clues and landmarks.
