Abstract: There is a keyboard assembly for a handheld device, comprising a housing having a first section and a second section. The keyboard assembly has a plurality of slots formed on the first section. A printed circuit board (PCB) is disposed between the first and second sections. A key mat is sandwiched between the first section and the PCB, the key mat having a plurality of fixed keys and a plurality of interchangeable keys, each key protruding from its corresponding slot on the first section. The plurality of interchangeable keys, each has an identification means configured to provide each interchangeable key with a unique identity, such that when each interchangeable key is replaced onto another slot on the first section, its unique identity remains with the interchangeable key.

Abstract: A method and an apparatus for recognizing different users in a household without having the users to register or enroll their biometric features are provided. The apparatus may leverage sensors integrated with a remote control device or connected to a media device and create pseudo-identity of a user when the user is consuming the content services from media device. When pseudo-identity is created, user's content preference, user's viewing habit, and user's viewing behavior with respect to the content, may be associated with more than one pseudo-identity to better identify the same user. In subsequent usage, personalized services, such as personalized guide & programs, user-selected preferences, targeted advertisement, or content recommendation, may be provided by service provider to user in a subtle and natural manner.

Abstract: A remote controller unit is provided. The remote controller unit may include a navigation keypad area that includes one or more navigation keys. The one or more navigation keys may be configured to move a cursor on a display device associated to a computing device or select one or more user interface items on the display device. The remote controller unit may include a fingerprint input component arranged in the navigation keypad area. The fingerprint input component may be configured to capture a plurality of fingerprint frames of a user in response to the navigation keypad area being touched by the user to move the cursor or select the one or more user interface items on the display device. The fingerprint input component may be a fingerprint input transducer or sensor.
