TrewGrip has launched a product for smartphones that reverses the QWERTY keyboard and brings it to the back for "rear typing".
The TrewGrip asks the users to type backwards on the bottom of the device itself, and as the user types, corresponding lights illuminate on the device's top confirming that correct key has been pressed, the Verge reports.
Tab, enter, space, and back are the only buttons on the front of the TrewGrip and can be pressed using your thumbs, the report added.
The TrewGrip uses Bluetooth to connect to the smartphones or small tablets, which it holds in place using a sticky pad on its front.
According to the report, the device can also connect to TVs and computers.
