Directed reading mode for portable reading machine
A method of operating a reading machine includes receiving an image and receiving an user-initiated command. The reading machine interprets the command to determine the portion of the image to process.
1. A method of operating a reading machine, the method comprising:
capturing an image of a physical scene being viewed by an image input device associated with the reading machine;
mapping the image of the physical scene to a reference to permit the user to navigate the physical scene;
receiving a user-initiated command in an image or a series of images processed by the reading machine to navigate the physical scene according to the mapping to the reference by;
capturing the image or the series of images to process the user command, at a different, lower resolution than a resolution used to capture the physical scene;
detecting the presence of a user gesture in the image or series of images at the lower resolution;
interpreting the user gesture as the command to the reading machine to determine a portion of the image to process; and
processing the image to recognize text that appears in the portion of the image and form an output of the text according to the user command.

receive an image of a physical scene being viewed by an image input device associated with the reading machine;
form a map of the image of the physical scene to permit the user to navigate the physical scene;
receive an user-initiated command in an image or a series of images processed by the reading machine to navigate the physical scene according to the mapping to the reference by instructions to:
capture the image or the series of images to process the user command, at a different, lower resolution than a resolution used to capture the physical scene; and
detect the presence of a user gesture in the image or series of images at the lower resolution;
interpret the user gesture as the command to the reading machine to determine a portion of the image to process; and
process the image to recognize text that appears in the portion of the image and form an output of the text according to the user command.
