The Digital White Cane is a primary electronic mobility head mount aid for use by people who are blind or visually impaired; it is a major "step forward" in assistive technology that allows safe obstacle avoidance and permits navigation around obstacles both in the user's forward path and whatever direction the user turns their head before walking in that direction, giving valuable protection at head/chest height while the cane still cover ground obstacles.
I happened to have the Sharp IR sensors but there are other options. Sonar is cheap. Few $ from China but large. There are a lot of new Time of Flight sensors coming on the market. Some have a line of pixels. For those we would have to add a lens. Surplus Shed has lots of cheap lenses.
