Methods and apparatus for triggering directional data capture based on
pointing direction are described. In an embodiment, the data captured is
an image and a camera is described which includes a sensor for detecting
the direction in which the image sensor of the camera is pointing. When
the sensed pointing direction is one in which a worthwhile image is
likely to be taken, the camera is triggered to capture a new image. The
determination of when to capture a new image uses a metric based on the
sensed direction and one or more specified trigger conditions.
