RIM files patent for angular BlackBerry keyboard

Research in Motion could soon introduce a BlackBerry smartphone with a uniquely ergonomic keyboard design, if information from a new patent filing proves accurate. Filed in June of last year, the application would tilt the keys on the left and right sides of the keyboard at 45-degree angles. The technique allows both for larger, more easily struck keys than the traditionally right-angled keyboards on most larger smartphones while also easing strain on the hands and thumbs for extended typing sessions, RIM says.

The Canadian phone producer has yet to incorporate the patent in a finished product but has developed versions for several international keyboards, including QWERTY, AZERTY, and also Dvorak layouts. The upcoming release of the BlackBerry 9000 series touchscreen phones casts doubt on the use of the technology early next year, though it does not preclude the angled keyboard's use in an upgrade 8300 Curve or 8800 model.
