This invention proposes three states to adaptively switch mobile device keyboard modes. They are landscape mode, holding mode and split mode. Landscape mode is selected by default when keyboard is activated, and the landscape keyboard is presented to user in this mode. When there is pressure signal detected from both left/right sides, this invention turns into the holding mode. In the holding mode, the holding side is set. If there is no signal from holding side for a while, it will return to landscape mode; if a signal detected from holding side exceeds the predefined pressure threshold, our invention goes into split mode. In split mode, a split keyboard is going to be shown to users. When there is no signal from holding side for a while in split mode, the invention will turn back to landscape mode and the keyboard will also revert back to landscape.
