A design for texting with the device orientation inverted. This is just a patent application, and not a real product. It’s an interesting idea, though, because it doesn’t ask people to learn new input systems but rather just change the orientation of the device.
“Typing text messages in this manner is awkward, as the mobile is merely held pinched between the middle finger and the palm, while most of the handset extends unstably beyond the user’s palm. Furthermore, the thumb’s range of movement is restricted by the lower orientation of the keypad.”
