Provided we actually get Google Glass at some point, one of the main problems would be interacting with it. You can’t smudge your glasses with your dirty fingers, so how does one type and select options for the device? Today, Google filed for a patent that would allow Glass to project a virtual keyboard onto hands, arms and pieces of furniture and allow you to type and let the computer do the heavy lifting.
From the looks of it, this is a pretty inventive answer to one of the biggest problems with Google Glass. The unfortunate part, as with most of Glass, is that we still don’t know if or when we will see any of this. Maybe we’ll see a little bit at the Glass Foundry events in a few weeks, but don’t hold your breath.
