Described are systems and techniques configured to determine and present information to a user of a materials handling facility. As the user moves through the facility, information is dynamically presented to the user on one or more displays using a user interface. The user interface may be presented on the display as the user approaches, and presentation may cease as the user moves away. The amount of information, size of elements presented on the display, and so forth may be based on kinematic data about the user. The kinematic data may include position, speed, orientation, and so forth.
