Assistance systems and methods for a material handling vehicle

A system for providing an overlaid image to an operator of a material handling vehicle through an optical system, the system comprising:

• a training reinforcement assistance device having a frame supporting an imager and a display, the display operably coupled with the optical system, wherein the frame is configured to be supported on a head of an operator;
• a controller coupled with the frame;
• a control unit operably coupled with the material handling vehicle and communicatively coupled with the controller, wherein the control unit communicates at least one vehicle kinematic of the material handling vehicle to the controller;
• a locating system including at least one of an accelerometer and a gyroscope, the locating system communicatively coupled with the controller and configured to provide orientation information of the frame from the at least one of an accelerometer and a gyroscope to the controller;
• and
• a first fiducial positioned on the material handling vehicle, the imager configured to detect the first fiducial to orient the frame relative to the material handling vehicle, wherein the controller is configured to determine a location of the frame based on the detected first fiducial and the orientation information,
• wherein the display is configured to generate an image based on the location of the frame and the at least one vehicle kinematic.

A system comprising:

• a material handling vehicle;
• a control unit operably coupled with the material handling vehicle;
• a training reinforcement assistance device having a frame supporting an optical system, wherein the optical system is configured to display virtual content and enable viewing of at least a portion of a surrounding environment, wherein the frame is configured to be supported on a head of an operator;
• an accelerometer operably coupled with the frame and configured to detect an orientation of the frame;
• an imager operably coupled with the frame and configured to produce an overlaid image on at least the portion of the surrounding environment;
• and
• a controller operably coupled with the imager and the optical system;
• a fiducial marker positioned on the material handling vehicle, the imager configured to detect the fiducial marker to orient the frame relative to the material handling vehicle and determine a location of the frame;
• wherein the control unit operatively coupled with the material handling vehicle is communicatively coupled with the controller operatively coupled with the optical system and wherein the control unit communicates at least one vehicle kinematic of the material handling vehicle to the controller;
• and
• wherein the controller is configured to calculate a position of the overlaid image based on the orientation of the frame and the vehicle kinematic of the material handling vehicle, and wherein the overlaid image includes a pivot point defined by the material handling vehicle.
