Systems and methods for human gait analysis, real-time feedback and rehabilitation using an extended-reality device

A system for performing a gait analysis, comprising:

• an AR headset configured to be worn on a head of a subject, the AR headset comprising:
• a frame structure configured to be worn on the head of the subject;
• one or more image sensors carried by the frame structure;
• and
• a display system for displaying virtual images generated by a computer system;
• the computer system having at least one computer processor, memory, a storage device, and a gait-analysis software application stored on the storage device, the computer system in communication with the one or more image sensors and the display system, the computer system configured to program the system to perform a process comprising:
• capturing image data from the one or more image sensors headset as the subject walks;
• performing a SLAM analysis on the image data to determine head-pose data of the head of the subject;
• and
• determining one or more gait attributes of a gait of the subject by analyzing the head-pose data using a gait-metric prediction algorithm.

A non-transitory computer-readable medium having software instructions stored thereon, the software instructions executable by a computer processor to cause the processor to cause an AR computing system to perform a process for performing a gait analysis using an AR headset worn on the head of a subject, the process comprising:

• capturing image data from one or more image sensors disposed on the AR headset as the subject walks;
• performing a SLAM analysis on the image data to determine head-pose data regarding a position and location of the head of the subject;
• and
• determining one or more gait attributes of a gait of the subject by analyzing the head-pose data using a gait-metric prediction algorithm.
