Doesn't seem that far fetched. It's clearly an answer to Googles Android glasses. You cannot talk about keeping your head up when using a gadget and not be referring to a HUD (head(s)-up display). I hear that MS are trying to do the same as Google and Apple (they've filed some patents for it) so they may be doing it through Nokia.
