We've seen plenty of gadgets
designed to aid the visually impaired
, but none quite like this so-called "Tactile Wand" concept from designer Jin Woo Han, who's no stranger to nifty concept devices
. Obviously taking a few cues from another familiar "wand
," this would-be device employs a sensor on the front to determine the distance to the object it's pointed at, which gets relayed to the user in the form of varying levels of vibration. Needless to say, there's no indication of it actually moving beyond the concept stage, but it certainly doesn't seem beyond the realm of possibility.
