There are some cool things that you can do with heads up displays, but you need a good deal of space with todays technology in order to get something that is cost-productive. I’m pretty sure I’m not the only one to want something like sun glasses or even reading glasses that can do text searches for me straight from a book or piece of paper. Or even something that can read a piece of paper or street sign and translate it to another language.
A device that you can do this with, that you may already be wearing with enough space, are ski goggles. Now this winter was extremely mild, but maybe next year there will be some advancements to these technologies. First, check out the word lens app for iPhone and then check out the heads up display for ski goggle. After that, imagine if we could get these into our eye or sun glasses.
