If you have standard human vision (even if assisted by glasses), chances are you’re adept at finding things, people, and paths to them. But if you have impaired vision, or none at all, countless tasks that are simple for fully sighted people become difficult, dangerous, or even impossible. Fortunately, plenty of new high-tech tools offer assistance, including robot guide dogs, a cane-bot (looking a bit like a small R2D2 with giant wheels), multiple types of smart glasses with descriptive audio, and even a haptic vest for blind dogs.
