Assisting a vision-impaired user with navigation based on a 3D captured image stream
First Claim
1. A computer-implemented method for assisting a user with information about an environment relative to the user, comprising:
- capturing a three-dimensional movement of a moving object within the environment, wherein the three-dimensional movement is determined using at least one image capture device aimed at the moving object;
predicting a physical movement mobile path of the user based on a detected direction and pace of the physical movement of the user;
determining whether the movement of the moving object will intersect with the mobile path of the user; and
informing the user whether the movement of the moving object will intersect the mobile path of the user by adjusting an intensity of a tactile feedback along at least one point of a tactile glove worn by the user to simulate the change in surface area the user would feel if actually intersecting with the moving object, without the user having to actually approach the detected moving object.

Abstract
An object-enabled navigation system assists a vision-impaired user in navigating an environment. The system captures 3D movement of a moving object within the environment, wherein the three-dimensional movement is determined using at least one image capture device aimed at the moving object. The system predicts a mobile path of the visually-impaired user. The system determines whether the movement of the moving object will intersect with the mobile path of the vision-impaired user and informs the vision-impaired user whether the movement of the moving object will intersect the mobile path of the vision-impaired user.

8. A system for assisting a user with information about an environment relative to the user, comprising:
-
an object processing system, comprising at least one processor, operative to capture a three-dimensional movement of a moving object within the environment, wherein the three-dimensional movement is determined using at least one image capture device aimed at the moving object, predicting a physical movement mobile path of the user based on a detected direction and pace of the physical movement of the user, and determining whether the movement of the moving object will intersect with the mobile path of the user; and a navigation system, comprising at least one additional processor, operative to receive from the object processing system the determination whether the movement of the moving object will intersect with the mobile path of the user and control outputs for informing the user whether the movement of the moving object will intersect the mobile path of the user by adjusting an intensity of a tactile feedback along at least one point of a tactile glove worn by the user to simulate the change in surface area the user would feel if actually intersecting with the moving object, without the user having to actually approach the detected moving object. - View Dependent Claims (9, 10, 11)

12. A computer program product for assisting a user with information about an environment relative to the user, the computer program product comprising:
-
one or more computer-readable tangible storage devices; program instructions, stored on at least one of the one or more storage devices, to capture a three-dimensional movement of a moving object within the environment, wherein the three-dimensional movement is determined using at least one image capture device aimed at the moving object; program instructions, stored on at least one of the one or more storage devices, to predict a physical movement mobile path of the user based on a detected direction and pace of the physical movement of the user; program instructions, stored on at least one of the one or more storage devices, to determine whether the movement of the moving object will intersect with the mobile path of the user; and program instructions, stored on at least one of the one or more storage devices, to inform the user whether the movement of the moving object will intersect the mobile path of the user by adjusting an intensity of a tactile feedback along at least one point of a tactile glove worn by the user to simulate the change in surface area the user would feel if actually intersecting with the moving object, without the user having to actually approach the detected moving object.
