A physical task is set by adjusting complexity of the walking route. A degree to which the user follows the walking route is calculated, and the physical task is adjusted based on the degree.

Apparatuses, systems and methods associated with a travel assistance system. A wearable personal navigation device may include a communication system, an indicator, and a processor coupled to the communication system and the indicator. The processor may be configured to generate a request for a navigation path from a location to a destination and transmit the request to a node of the network. The processor may be configured to determine the direction of travel from the location of the user based on a first navigation path received from the node of the network in response to the request, wherein the first navigation path includes at least one modification from a second navigation path, wherein the modification is based on data received by the network from a remote device that indicates an object, and cause the indicator to indicate the direction of travel. Other embodiments may be described and/or claimed.

A mobility tool for the blind and visually impaired includes a rod and an earpiece. The earpiece is configured to position on an ear of a user so that a first speaker is positioned proximate to an ear canal of the ear. A sensing module is coupled to a lower end of the rod and is configured to detect a temperature hazard, a water hazard, and a traffic hazard. A navigation and communications module is coupled to an upper end of the rod and is operationally coupled to the sensing module and the earpiece. The navigation and communications module comprises a GPS transceiver that is configured to send and receive location coordinates. The sensing module is configured to detect a respective hazard along a route, positioning the first speaker to selectively broadcasting directions for the route and a warning of the respective hazard to the user.

A multi-functional guide stick for the visually impaired is an apparatus with built in navigation, speech recognition, Bluetooth capabilities, fingerprint security, and close proximity environmental analysis. The apparatus is configured to analyze the user's surroundings and provide audio feedback. An auditory navigation system continuously provides the user with their current geographic location, preferably via Bluetooth headset or speaker. In addition, the apparatus also accepts voice command inputs, processes navigation requests for various destinations, and subsequently audibly conveys turn-by-turn navigation to reach said destination. Furthermore, with the use of a plurality of sensors, objects in close proximity, including vehicles moving at high speeds, are detected and information relayed to the user through auditory signals. The apparatus allows a visually impaired user to navigate the streets of the city, dangerous cross sections, and avoid obstacles with ease.

Systems and methods for communicating with a guide animal are provided. One embodiment of a method includes determining a first command to provide to a user to proceed to a destination, determining a second command to provide to the guide animal to correspond with the first command, and outputting the first command to direct the user toward the destination. Some embodiments include outputting the second command to direct the guide animal toward the destination, where the second command is outputted to be imperceptible by the user but is perceptible by the guide animal.

The embodiment of the present disclosure discloses an intelligent blind guide method and apparatus, and relates to the field of artificial intelligence, so as to solve the problem that an intelligent blind guide system requires the whole-process intervention of an artificial customer service staff, which results in high work intensity. The intelligent blind guide method includes: obtaining a confidence of an intelligent blind guide according to sensor information, wherein the confidence indicates the reliability of blind guide information generated according to the sensor information without artificial decision; generating the blind guide information according to the sensor information if the confidence is greater than or equal to a preset threshold, and importing artificial decision to generate the blind guide information if the confidence is less than the preset threshold. The embodiment of the present disclosure is applied to a blind guide helmet.
