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.

1-20. (canceled)
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.
A computer program product residing on a computer readable medium for operating a portable reading machine, the computer program product comprising instructions to:
- process 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
- apply optical character recognition to recognize text in the hierarchical document in the image in an order determined according to the command.
A portable reading machine comprising:
- a computing device;
- an image input device coupled to the computing device for capturing low resolution images and high resolution images;
- and
- a computer readable medium storing a computer program product for operating a portable reading machine, the computer program product comprising instructions to:
- receive a low resolution image to process the gesturing item and receive a high resolution image to recognize text;
- process 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;
- process the high resolution image to recognize text in the image, according to the command from the user to process the image as a hierarchical document;
- process different named sections of the image for speech synthesis in an order determined by the hierarchical document.
