    GPS is a good idea! A simple one with battery pack would still be within weight constraints. But how will the user utilize it? They'll probably either need to predefined destinations, or the GPS unit is smart enough to understand simple commands (like Home, Grocery, etc).

    However, for guiding blind users to avoid obstacles (like going on road), GPS should't be relied on considering its 5-10m positional accuracy.
