A supplemental control system for a materials handling vehicle includes a wearable wireless remote control device that is donned by an operator interacting with the materials handling vehicle and includes a docking area, a detachably mountable communications device, and a travel control. The communications device temporarily docks to the docking area during use of the supplemental remote control system to control movement of the materials handling vehicle and includes a wireless transmitter. The travel control is communicably coupled to the wireless transmitter, wherein actuation of the travel control causes the wireless transmitter to wirelessly transmit a travel request as a first type signal requesting the materials handling vehicle to move across a floor surface in a first direction.
