  "abstract": "Systems and methods provide assistance to an operator of a material handling vehicle. A training reinforcement assistance device has a frame supporting an optical system, the optical system being configured to display virtual content on a display, and to enable viewing of at least a portion of a surrounding environment; an imager operably coupled with the frame; an accelerometer operably coupled with the frame and configured to detect an orientation of the frame; an eye-tracking unit operably coupled with the frame and configured to detect a viewing direction of an operator; and a controller operably coupled with the imager and the display. The controller receives environmental information from at least one of the imager, the accelerometer, or the eye-tracking unit and to overlay the image of the environment to assist the operator in maneuvering a material handling vehicle based on vehicle kinematics of the material handling vehicle.",
