Abstract: An adaptive user interface device capable of implementing multiple modes of input and configuration may adapt to current user inputs, and may include configuration changes. In an aspect, an adaptive user interface device may be configured for a finger sensing in a touchpad mode, and configured for stylus sensing in a digital tablet mode. In another aspect, surface features of the adaptive user interface device may change shape, such as by raising buttons in response to entering a keyboard or keypad mode. Various mechanisms may be used for raising buttons, and may enable presenting buttons in a variety of shapes and locations on the interface. The configuration of the adaptive user interface device may depend upon the user actions and user identity. Configuration modes may be organized according to many levels enabling a single user interface to support a large number of input options functionality within a limited surface area.
