Right now tech companies fight about the phone you use. The next battle could be over the glasses you wear.
Microsoft is working on a device that delivers information about live events to a person wearing a head-mounted display. One of the drawings included in Microsoft's patent application shows the device could come in the form of eyeglasses.
"The information is provided about actions and objects occurring within an event and within the user's field of view," the application says.
The Microsoft device would connect to a processing unit that you could wear on your wrist like a band. The processing unit would connect to the glasses either via a wire or using a wireless technology such as Bluetooth.
That's some pretty cool technology Microsoft is working on, but the Redmond, Wash., company isn't alone.
Google's Project Glass is developing a similar set of eyeglasses and the company has already shown prototypes to the public via YouTube as well as at conferences. Google co-founder Sergey Brin practically wears a set of the glasses everywhere.
Google put early editions of its glasses on sale at its Google I/O conference this summer for $1,500 a unit. The company said Google said it hopes to sell them to the public by 2014.
Apple, meanwhile, received a patent for a head-mounted device this year.
It's unclear when or whether Microsoft would sell its head-mounted device.
