Claim 0:
1. 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 portion of the plurality of pixel cells as a patch representing at least a portion of the identified object;
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;

dynamically updating a location of the patch among the plurality of pixels based on the estimated trajectory of the patch by updating which of the plurality of pixel cells is included in the patch while the computing system is operating; and
controlling the sensor to selectively provide, to the processor, image information from the portion of the plurality of pixel cells in the patch without providing image information from pixels of the plurality of pixels that are outside of the patch.
