Navigation using portable reading machine

A computer program product tangibly stored on a computer readable hardware storage device, the computer program product for navigation of a physical environment, comprises instructions for causing a computer device to:

• capture images of physical scenes, at least some of the images containing at least one or more of objects, landmarks, and/or signs in the images of the physical scenes;
• process the captured images to recognize existence of the at least one or more objects, landmarks, and/or signs in the physical scenes;
• associate the recognized objects, landmarks and/or signs in the images to nodes, the nodes corresponding to the objects, landmarks, and/or signs;
• associate, with the nodes, navigation descriptions of the corresponding one or more of the objects, landmarks, and/or signs;
• and
• generate a construct relating the nodes to each another, the nodes being related based, at least in part, on the navigation descriptions.

A computer implement method for navigation of a physical environment, comprises:

• capturing images of physical scenes using an image input device, at least some of the images of the physical scenes containing at least one or more of objects, landmarks, and/or signs;
• processing by a computing device the captured images to recognize existence of the at least one or more objects, landmarks, and/or signs in the physical scenes;
• associating by the computing device the recognized objects, landmarks, and/or signs contained in the images to nodes that correspond to the objects, landmarks, and/or signs;
• associating by the computing device navigation descriptions of the corresponding one or more of objects, landmarks, and/or signs;
• and
• generating by the computing device a construct relating the nodes to each another, the nodes being related based, at least in part, on the navigation descriptions.

A device comprising:

• one or more processing devices;
• memory to store instructions that are executable by the one or more processing devices to:
• capture images of physical scenes associated with a user-planned path through the physical scene, at least some of the images containing at least one or more of objects, landmarks, and/or signs in the physical scenes;
• process the captured images to recognize existence of the at least one or more objects, landmarks, and/or signs in the images of the physical scenes;
• load a map associated with the physical scenes, which includes associated recognized objects that exist in the physical scenes;
• load the user-planned path through the physical scene;
• determine based on the captured images of the physical scene and recognized objects in the physical scenes, a present location of the user along the planned path;
• generate navigation description instructions;
• and
• render the navigation description instructions to the user.
