RearType - Text Entry for Mobile Devices
RearType is a project from Microsoft and others, that explores a text entry system for mobile devices using normal keyboard keys that are placed on the back of the device. This approach helps to resolve the problem where a users fingers and hands occlude the touch point(s).
Earlier work in this area includes Lucid Touch, by Patrick Baudisch https://www.kf12.com/blogs/techno/lucid-touch/, and the Grippity Keyboard https://www.kf12.com/blogs/techno/grippity-keyboard/ and https://www.grippity.com/
In RearType, a standard keyboard layout is split and rotated so that hands gripping the device have the usual keys under the fingers. This allows for 10-finger, tactile, touch-typing which may be better and quicker than using an on-screen keyboard for touch devices.
The paper 'RearType: Text Entry Using Keys on the Back of a Device' will be presented at Mobile HCI 2010 ( https://mobilehci2010.di.fc.ul.pt/ )
