Abstract
A portable reading machine that operates in several modes and performs image preprocessing to prior to optical character recognition. The portable reading machine receives a low resolution image and a high resolution image of a scene and processing the low resolution image to recognize a user-initiated gesture using a gesturing item that indicates a command from the user to the reading machine and the high resolution image to recognize text in the image of the scene, according to the command from the user to the machine.

21. A method of operating a portable reading machine, the method comprising:
-
processing by a computing device in the reading machine, an image, to recognize a user-initiated gesture using a gesturing item the gesture indicating a command from the user to the reading machine when recognizing text in the image, the command specifying an order by which the reading machine navigates through named portions of a hierarchical document in the image; and applying optical character recognition to recognize text in the hierarchical document in the image in an order determined according to the command. - View Dependent Claims (22, 23, 24, 25, 27, 28, 29)
