Systems and methods for assessing ergonomics utilizing visual sensing

A system for assessing ergonomics of a human user in an environment, the system comprising:

• a visual sensor configured to generate a visual skeletal signal of the human user in the environment;
• an output display configured to present one or both of instructions for participating in ergonomic evaluations and an ergonomic report;
• an electronic controller including a processor and configured to
• display a prompt for the human user to perform an interactive task, wherein generation of the visual skeletal signal is performed by the visual sensor while the human user performs the interactive task;
• receive the visual skeletal signal from the visual sensor,
• determine a posture sample based on the visual skeletal signal, the posture sample including skeletal information, the skeletal information including one or both of joint information and positioning information,
• compare the posture sample with an ergonomically ideal posture sample, the ergonomically ideal posture sample being specific to the human user alone,
• determine the ergonomic report based on the comparing of the posture sample and the ergonomically ideal posture sample, and
• provide signals, to the output display, for presenting the ergonomic report to the human user.

A user station configured to assess ergonomics of a human user in an environment, the user station including:

• a work surface disposed in the environment;
• a visual display configured to present the human user with one or both of instructions for participating in ergonomic evaluation and an ergonomic report, as well as a prompt to perform a task;
• a visual sensor configured to generate, at least, a visual skeletal signal of the human user at the work surface in the environment while the human user performs the task;
• an electronic controller, including a processor, configured to
• receive the visual skeletal signal from the visual sensor,
• determine a posture sample based on the visual skeletal signal, the posture sample including skeletal information, the skeletal information including one or both of joint information and positioning information,
• compare the posture sample with an ergonomically ideal posture sample, the ergonomically ideal posture sample being specific to the human user alone,
• determine the ergonomic report based on the comparison of the posture sample and the ergonomically ideal posture sample, and
• provide signals to the visual display for presenting the ergonomic report.
