RIM has filed a new patent according to which new Blackberry handset will have a rotatory keyboard. The patent provides a system to move the keyboard down and twist to make it more comfortable. Appropriate signs on the keys should guide the user to the proper use.
Here are a some images of the new patents filed by RIM which also gives an idea of how the new device look like.
The engineers of RIM writes;
“In a first aspect, a handheld electronic device, such as a smartphone, has a first device member and a second device member that are connected via a connector. The second device member is rotatable about a rotation axis that is canted relative to an axis of the second device member. As a result, when the second device member is rotated between a first position and a second position, its orientation changes. This may facilitate, for example, switching the handheld electronic device between a text entry mode and a telephone mode.“
