An interesting patent application from Google that was published by the US Patent Office recently shed light on specific augmented reality features that are likely related to Project Glass. Google's filing states that the glasses in this new invention are designed to enhance a user's vision and experience beyond its limited 180 degree field of view (FOV). Google's invention will enable the user to be aware of objects that are outside their field of view. For the most part, the application appears to be well suited for tourists, though it does have some interesting yet weakly defined alternative uses in mind. A unique aspect to Google's design could be found in a line of tiny lights positioned on the inside bottom of the frame as noted in our cover graphic above. A particular light within that line will illuminate when there's something of interest to view at a particular angle within the field of view of the glasses. It could be a building, structure or person.
