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.
