Navigation using portable reading machine
First Claim
Patent Images
1. 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 containing at least one or more objects, a first one of the images taken in a first direction from a first object to a next object in the physical scene, and a subsequent one of the images taken in a second direction from a subsequent object back to the first object;
record distance from where each image was taken to each object, and when the images are taken;
associate the objects, contained in the images to nodes that correspond to the objects;
associate, with the nodes, parameters relating to the objects; and
generate a construct relating the objects to each other, the objects being related based, at least in part, on the parameters.

1. 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 containing at least one or more objects, a first one of the images taken in a first direction from a first object to a next object in the physical scene, and a subsequent one of the images taken in a second direction from a subsequent object back to the first object; record distance from where each image was taken to each object, and when the images are taken; associate the objects, contained in the images to nodes that correspond to the objects; associate, with the nodes, parameters relating to the objects; and generate a construct relating the objects to each other, the objects being related based, at least in part, on the parameters. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A computer program product tangibly embodied on a computer readable medium for navigation of a physical environment, comprises instructions for causing a computer device to:
-
capture images of physical scenes containing at least one or more of objects, a first one of the images taken in a first direction from a first object to a next object in the physical scene, and a subsequent one of the images taken in a second direction from a subsequent object back to the first object; record distance from where each image was taken to each object, and when the images are taken; associate the objects contained in the images to nodes that correspond to the objects; associate, with the nodes, parameters relating to the objects; and generate a construct relating the objects to each other, the objects being related based, at least in part, on the parameter.

30. A computer implement method for navigation of a physical environment, comprises:
-
capturing images of physical scenes using an image input device, the physical scene containing at least one or more of objects, a first one of the images taken in a first direction from a first object to a next object in the physical scene, and a subsequent one of the images taken in a second direction from a subsequent object back to the first object; recording distance from where each image was taken to each object, and when the images are taken; associating by a computing device the objects, contained in the images to nodes that correspond to the objects; associating with the nodes in the computing device, parameters relating to the objects; and generating by the computing device a construct relating the objects to each other, the objects being related based, at least in part, on the parameter.
