My biggest concern is that one cannot comfortably & safely type while walking. Just let your imagination fly & type later at home? Anyway, I would first practice read-only browsing e.g. with Vuzix Tac-Eye LT¹ attached to iPhone (or smartphone of your choice). If that worked, I'd add one-hand bluetooth keyboard, such as FrogPad². Generally speaking, wearable computers are definitely the future, but the technology is not yet ready for the prime time. Today's virtual glasses are clunky, low-res and expensive; input methods are primitive.
