Abstract: Aspects may relate to a device to authenticate a user that comprises a processor and a sensor. The processor coupled to the sensor may be configured to: receive at least one fingerprint scan from the sensor inputted by the user during an enrollment process to define a fingerprint password, the at least one fingerprint scan including one or more partial fingerprint scans from a same finger or different fingers of the user; and authenticates the user based upon the defined fingerprint password inputted through the sensor by the user.

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.

Abstract: A portable electronic device (100,400) and user interface (425) are operated using a method including initiating entry of a content string; determining the most probable completion alternative or a content prediction using a personalized and learning database (430); displaying the most probable completion alternative or next content prediction; determining whether a user has accepted the most probable completion alternative or next content prediction; and adding the most probable completion alternative or next content prediction to the content string upon user acceptance.
