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 including a processor, a wireless communication transceiver, a light source, a memory and a mapping sensor, wherein the lighting device processor is coupled to the wireless communication transceiver, the memory, the light source, and the mapping sensor, the processor upon execution of programming stored in the memory is configured to control operations of the lighting device including the mapping sensor, the mapping sensor being configured to collect mapping data related to the area of the premises in which the lighting device is located; and a data storage for maintaining area mapping data collected by the mapping sensor of an area in which the lighting device is located in the premises, processed mapping data which is area mapping data that has been processed using image processing techniques, and mapping information including navigational information or indications, wherein the database is accessible by the lighting device processor; wherein the lighting device memory stores programming, and execution of the programming by the lighting device processor configures the lighting device processor to perform functions, including functions to:
receive a request from a user wearable device for processed mapping data for the area of the premises in which the lighting device is located; andin response to the request, deliver processed mapping data for the area of the premises in which the lighting device is located to the user wearable device.
