Interesting idea. I was wondering when I watched you elevator pitch was if this could could be an app for google glass or something like that. Not sure if anyone uses google glass. It would be cool if the EduHUD was able to determine if a student was lying by changes in their body temperature or something. As far as investing goes I am wary of having to create the hardware and the software. I would be more interested if it was just the hardware with many applications or just the software for a google glass thing.
