According to the patent, it describes eye-tracking technology which may or may not make its way into Google Glass. As is the case with patents, it’s sometimes hard to tell if a company has actual plans of making it a reality or if they are simply protecting their intellectual property, however given the nature of Google Glass, including eye-tracking technology certainly makes a lot of sense.
Basically with eye-tracking technology, users will be able to walk down the street and look at various objects, like restaurant signboards and from there, Google will be able to pull up reviews for the place. It could also be used in shops where users could look at objects and find out more information about it, like possible cheaper deals online or other stores, and so on.
It’s an interesting idea and one that we wouldn’t mind seeing Google implement into their next Google Glass, which according to the company is expected to be reintroduced by the end of the year.
