Microsoft has filed a patent for a new slide-able Windows Phone with detachable accessories.
The patent was filed with the U.S. Patent and Trademark Office in March, 2010 and was published for all to see on Thursday. Microsoft’s patent description describes the idea of a mobile device with companion second devices. “The second devices are releasably attachable to the first device and are interchangeable with each other,” says Microsoft in part of its patent application. The device appears to be able to act as a game controller, physical keyboard and remote control.
The Unwired View, who spotted the patent, notes that the secondary part of the device could also be used for additional batteries. The secondary accessories can be used independently of the original device to act as a second phone or remote etc. The device appears to be a Windows Phone as it features the prominent Windows flag and back button. The search button is missing but Microsoft filed the patent before Windows Phone 7 devices were available in retail markets.
Microsoft’s Windows Mobile slider devices were popular amongst business and power users. This type of device demonstrates the way that mobile devices are increasingly becoming an important part of every day life. The convergence of several different device types into one single device is inevitable and the software giant appears to be ready to offer such a solution in the future.
