They make fold up canes, so the box wouldn't have to be that big. But on a serious note, I do recall reading that this was/is the display of the future. A small laser (power limited, obviously) along with a small, possibly MEMS, mirror structure would individually activate the rods and cones of the eye to provide you with 36"(?) heads-up display. Resolution would be an interesting selling point in this case, as well. Eye movements would have to be tracked so that the display didn't jump around, but otherwise it seems feasible. I don't know where or if this technology has really gone anywhere. I'm sure there are, at least, government programs working on it. I would expect Sony to be working on it as well. >From there they can finally make a highly addictive disc-into-funnel head mounted video game.
