The point of using a long cane is to give sufficient time for a blind person to react to any obstacles hanging or on the ground or significant drops in the surphase.
Any technology that can help in detecting hanging objects (head height) is welcome. I wouldn't rely on technology to detect pits or steps going down unless the technology is 100% accurate or at least close to it.
