Mobile computing devices having rotationally exposed user interface devices

摘要

A mobile computing device includes a first housing that is rotationally coupled to a second housing, computing circuitry within the first housing and a display that is at least partially disposed within the first housing. The display is configured to visually display information from the computing circuitry to a user. A first user interface device and a second user interface device are at least partially disposed within the second housing. The second housing is configured to be rotated relative to the first housing between a closed position in which the first and second user interface devices are at least partially covered by the first housing, and a deployed position in which the first and second user interface devices are at least partially uncovered on opposite lateral sides of the first housing.
