SYSTEM AND METHOD TO ASSIST USERS HAVING REDUCED VISUAL CAPABILITY UTILIZING LIGHTING DEVICE PROVIDED INFORMATION

摘要

A lighting device obtains data related to objects and boundaries in an area in the vicinity of the lighting device, and a user wearable device provides a display (e.g. an augmented reality display based on the data related to the objects and the area boundaries) for a user/wearer. The lighting device includes a mapping sensor that collects data related to the objects and boundaries in the area. The user wearable device includes a camera or other optical sensor and wireless communication capability. The user wearable device is provided with mapping data that is presented on a display of the user wearable device. The communications and display capabilities allow the user wearable device to obtain room mapping information related to area in the vicinity of the lighting device in order to provide navigational assistance to a visually impaired person in the area.

主权项

1. A system, comprising:
a lighting device in an area of a premises, the lighting device including:
a lighting device processor,a wireless communication transceiver,a light source, anda memory that stores programming instructions, wherein the lighting device processor is coupled to the wireless communication transceiver, the memory, and the light source; and a data storage for maintaining processed mapping data and mapping information of an area of the premises in which the lighting device is located, wherein:
the processed mapping data is area mapping data that has been processed using image processing techniques, andthe mapping information includes navigational information or indications; wherein the lighting device processor when executing the programming instructions stored in the memory configures the lighting device processor to control operations of the lighting device and perform functions, including functions to:
in response to a request for processed mapping data, deliver processed mapping data for the area of the premises in which the lighting device is located to a user device;update the mapping data for the area of the premises to identify locations of moveable objects within the area as the moveable objects move within the area; anduse the updated mapping data as the user device moves within the area.
