AlliO PROM is an application programming interface (API) that enables real-time integration between the AlliO audience measurement system and Scala’s digital signage software platform. Using PROM, end users can adapt their digital signage content to match viewing audience demographics for proactive advertising. TruMedia’s AlliO uses sensors to analyze facial images of people watching the displays in real time, providing business-critical data such as audience counts, individual exposure times, and gender and age group demographics. This data can be used to select specific media appropriate for the audience. This allows for better media planning and targeted advertising.
