Abstract: Systems and methods for navigating an environment are provided. A method includes determining a starting location and a destination location in an environment, receiving a graph representation of a map of the environment, determining a plurality of candidate paths from the starting location to the destination location, identifying which of the plurality of candidate paths is a shortest path from the starting point location to the destination object location, selecting the shortest path as a path to navigate from the starting location to the destination location, generating a token comprising one or more instructions for navigating the shortest path, and causing the token to be displayed on a display device of an interactive kiosk, wherein the one or more instructions comprise one or more instructions that cause a mobile electronic device to display a navigation guide for directing a user from the starting location to the destination location.

Abstract: A system of determining a distance between a mobile electronic device and an obstacle in an environment includes an electronic device, and a computer-readable storage medium. The computer-readable storage medium includes one or more programming instructions that, when executed, cause the electronic device to obtain from a camera of a mobile electronic device one or more images of one or more obstacles in a surrounding environment, and apply a convolution neural network to one or more of the obtained images to generate a one-dimensional array of depth perception estimates. The array includes one or more angle-distance pairs. an angle value of each angle-distance pair represents an angle of one or more of the obstacles relative to the camera. A distance value of each angle-distance pairs represents an estimated distance between the camera and one or more of the obstacles at the corresponding angle of the angle-distance pair.

Abstract: A system of determining a location of a mobile electronic device in an indoor environment includes an electronic device and a computer-readable storage medium having one or more programming instructions. The system determines an initial position of a mobile electronic device in an indoor environment and an initial heading of the mobile electronic device, initializes a set of particles, determines a relative location of the mobile electronic device, detects a move associated with the mobile electronic device, creates a subset of the set of particles based on the move, determines a distance between the relative location and a nearest obstacle that is encountered along a path. The system filters the particles in the subset, estimates an actual location of the mobile electronic device, and causes a visual indication of the actual location to be displayed to a user via a display of the mobile electronic device.
