Intelligent mobility aid device and method of navigating and providing assistance to a user thereof

摘要

An intelligent navigation device is provided for actively collecting data about a user and the surrounding environment, drawing helpful inferences, and actively aiding the user in navigation, environmental awareness, and social interaction. The intelligent navigation device may include cameras for detecting image data regarding the surrounding environment. The intelligent navigation device may include a GPS unit, an IMU, and a memory for storing previously determined user data. The intelligent navigation device may include a processor for determining a desirable action or event based on the image data, data detected by the GPS unit or the IMU, or a recognized object in the surrounding environment. The processor may further determine a destination and provide navigation assistance to the user for reaching the destination. The intelligent navigation device may convey output data using a display, a speaker, a vibration unit, a mechanical feedback unit, or an electrical stimulation unit.

主权项

1. An intelligent guidance device, comprising:
a plurality of wheels for travelling on a ground surface; a platform coupled to the plurality of wheels; an inertial measurement unit (IMU) coupled to the platform and configured to detect inertial measurement data corresponding to a positioning, a velocity, or an acceleration of the intelligent navigation device; a global position system (GPS) unit configured to detect location data corresponding to a location of the intelligent navigation device; a plurality of cameras coupled to the platform for detecting image data corresponding to a surrounding environment of the intelligent guidance device; a memory storing object data regarding previously determined objects and storing previously determined user data regarding a user of the intelligent guidance device; a processor connected to the IMU, the GPS unit, and the plurality of cameras, and configured to:
proactively recognize an object in the surrounding environment by analyzing the image data based on the stored object data and at least one of the inertial measurement data or the location data,proactively determine a desirable event or action based on at least one of the recognized object, the previously determined user data, or a current time or day,proactively determine a destination based on the determined desirable event or action,proactively determine a navigation path for navigating the intelligent guidance device based on the determined destination, the image data, and at least one of the inertial measurement data or the location data, andproactively determine output data corresponding to the determined navigation path; a display for proactively displaying a first image based on the output data to provide visual information to the user based on the navigation path and proactively displaying a second image based on the determined desirable event or action; and a speaker for proactively providing first audio information to the user based on the output data and second audio information based on at least one of the recognized object or the determined desirable event or action.
