When you think of a touch screen phones you think of the front display. With that display you interact with your phone by swiping up, down, left or right, but in the future we may not be using the front display at all to interact with our smartphones or tablets. Google has come with with an innovative idea.
Google might be looking to introduce touch controls on the rear of its devices. The search giant has applied for a patent for rear controls on devices. Patent Bolt reports that the US Patent and Trademark Office (USPTO) published the patent, which shows that backside controls will be there in future smartphone which will help you turn the pages of an ebook, scroll through an article on the web, or flip through images or music albums in a playlist.
