Google has applied for another patent relating to its head-mounted display project, Glass
. Titled "Wearable Computer with Superimposed Controls and Instructions for External Device," the application
details how the headwear would provide information and virtual controls for other electrical items, such as a refrigerator.
Using a combination of communication techniques, including Bluetooth, infra-red, QR codes, RFID, and general visual identification of an object, Glass would offer controls that appear over the item in the person's vision, according to Engadget
. The user would then be able to adjust the controls in some manner, though the patent does not mention how this would take place. Though this could be by detecting a "touch" of an augmented reality control using the onboard camera, reacting to voice commands, or on-device buttons, it could also make use of another patent application filed last year, which used a textured ring
to help with two or three-dimensional positioning, and so could potentially allow for in-air "pushing" of buttons.
Though being filed, it is unlikely for this sort of technology to be put in place by the time Glass goes on sale
. Such a system would require for Glass to interact with a multitude of other devices in order to function, something that will take a considerable amount of time to accomplish.
