Claim 8:
9. A method of operating a computing system comprising a sensor worn by a user and a processor configured to process image information, the sensor comprising an image array of a plurality of pixel cells generating image information for respective regions in a field of view of the sensor, the method comprising:
analyzing one or more images depicting a vicinity of the user;
identifying, based on analyzing the one or more images, an object in a physical world in the vicinity of the user;
identifying a patch based at least in part on a portion of the identified object;
selectively providing, from the sensor to the processor, image information from a portion of the plurality of pixels based at least in part on correspondence between the patch and the portion of the plurality of pixel cells;
estimating a trajectory of the patch among the plurality of pixels with respect to coordinates of the image array, the estimating comprising:
constructing a model of the object's motion in the physical world and a model of the image array's motion with respect to the physical world; and
computing the trajectory based on the model of the object's motion within the physical world and the model of the image array's motion with respect to the physical world; and

enabling a plurality of portions of the plurality of pixels cells of the sensor at different times based at least in part on the estimated trajectory of the path, wherein the plurality of portions of the plurality of pixel cells comprises the portion of the plurality of pixel cells, wherein enabling the portion of the plurality of pixel cells of the sensor comprises setting a first threshold value for the portion of the plurality of pixel cells and a second threshold for pixel cells outside the portion, the second threshold being greater than the first threshold.
