Abstract

A supplemental control system for a materials handling vehicle comprises a wearable control device, and a corresponding receiver on the materials handling vehicle. The wearable control device is donned by an operator interacting with the materials handling vehicle, and comprises a wireless transmitter to be worn on the wrist of the operator and a travel control communicably coupled to the wireless transmitter. Actuation of the travel control causes the wireless transmitter to transmit a first type signal designating a request to the vehicle. The receiver is supported by the vehicle for receiving transmissions from the wireless transmitter.
