1. A device comprising:
- a direction sensing module associated with a directional data capture module; and
a processor arranged to receive direction data from the direction sensing module, to trigger capture of a data set by the directional data capture module when a metric based on the direction data satisfies a trigger condition, and to access data relating to one or more previously captured data sets,wherein the data comprises a sum of distributions, each distribution being associated with a previously captured data set and being centered on a pointing direction associated with the previously captured data set; and
wherein each distribution is reduced with elapsed time from data capture.

Abstract
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.

8. A method of capturing data comprising:
-
sensing a pointing direction of a directional capture device; and initiating capture of a data set by the directional capture device when a metric based on the sensed pointing direction meets specified criteria, comprising; analyzing values in a data structure based on the sensed pointing direction, wherein the data structure comprises a set of values, each value being associated with a pointing direction and being dependent on one or more previously captured data sets; initiating data set capture if specified criteria are satisfied; updating the set of values in the data structure to the sensed pointing direction when data set capture is initiated; and reducing one or more of the values in the data structure according to predefined criteria. - View Dependent Claims (9, 10, 11, 12)
