Abstract: Described is a system and method for developing and dynamically updating user paths through a materials handling facility. A user path through a materials handling facility may be developed that will route a user past one or more items (e.g., pick list items, recommended items, wish list items, promotional items) planned for the user. If the user does not follow the user path, the user path may be dynamically updated to account for the current location of the user and/or to consider other actions performed by the user.

Abstract: Described are systems and techniques configured to present information to a user of a materials handling facility that stores items in inventory locations. Some or all of the information may be designated as confidential or have restrictions on presentation to reduce or eliminate dissemination of the confidential information to unauthorized users. A device such as a display carried by the user, mounted on a tote or shelf, and so forth may present the confidential information on a user interface. Presentation of the confidential information, acceptance of user inputs to the user interface, or both may be based on identification of an authorized user, a relative position between the user and the display, or other factors.

Abstract: Described is a system and method for routing output information to one or more of a plurality of output devices. In one implementation, output information that includes information to be presented and a location information identifying where the output information is to be presented may be generated by an output host. The output information is received by an output router that determines, based on the location information, an output device and routes the output information to the output device for presentation.
