Abstract: Systems, methods, apparatus, and software for monitoring and managing out-of-home (“OOH”) displays are provided. In one aspect, a system for monitoring an OOH display includes an OOH display device configure to display content to at least one subject. An interaction detector is configured to detect at least one interaction between the OOH display device and a subject, and provide data about such interaction. An input mechanism accepts input signals from the subject, and a display controller device accepts signals from the subject and OOH display device. A data processing and routing mechanism processes and exchanges the data.

Abstract: In an example of an embodiment of the invention, data relating to at least one impression of at least one person with respect to a display is detected, and a party associated with the display is charged an amount based at least in part on the data.
