Abstract
A visible-light based display system may be used to project visual guidance to picking and/or stowing agents in a materials handling facility dependent on their current location. The system may comprise a plurality of fixed-location display devices and/or mobile display devices coupled to a control system. The control system may send messages to particular ones of the display devices for projection of visual guidance usable to direct an agent to a particular inventory area in which an item is to be stowed or from which an item is to be picked, to identify a particular position within an inventory area, and/or to identify a particular item stored within an inventory area. The messages may include location, position, and/or descriptive information associated with an item to be stowed or picked. The projected visual guidance may include light or laser beams, text, graphics and/or images, and may be agent-specific, item-specific, and/or order-specific.
