Abstract
Navigation techniques including map based and object recognition based and especially adapted for use in a portable reading machine are described.
Claims30
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.

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.

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.
