> Can't obstruct fingertips, those are necessary for the cane and braille. Wear it on the left hand? Also, a glove is pretty quick to wear and remove. > I'd worry about it competing with cold-weather gear like mittens If it's useful, I don't think it would be an issue to create a "winter version". > I was thinking of a rigid head-mount If you hold your hand in front of your chest with the palm towards the chest, and wave it, you can appreciate how easy it is to scan the space in front of you. And the feedback would be directly on the fingertips, 1cm away from the sensor placed on the nail side of the finger, which makes for a very self-contained device. Also you get a free association between your self-perceived hand position and the space reading, which is nice. With a fixed head mount you need to constantly move your entire head to scan the space and the (tactile) feedback might be on an unrelated and less sensitive part of the body.
