You may eventually be able to operate your TV, refrigerator, or garage door through Google Glass.
Published today by the U.S. Patent and Trademark Office, a Google patent application called "Wearable Computer with Superimposed Controls and Instructions for External Device" describes a technology in which a Google Glass wearer could control a real object via a virtual display.
Beyond merely showing you details about an object, Google Glass would present a virtual control panel to let you interact with that object.
As described in the patent, you could "control the target device, provide input to the target device, receive instructions for operating the target device, receive status information regarding the target device, and/or receive other information related to the target device."
