For all the readers on this forum, maybe an oppertunity.
We've started with face recognition.
Just put a camera at the top of a screen, install the Seemetrix app, create an account over there,and connect the timeline via the Api to a type of person:
Seeemetrix recognizes the gender and age of a person, and sends an event to the DS-system.
For example: when a woman enters the area, content created for this target audience is shown. When a child enters, the content created for this audience is shown.
Works great, try it, you only need camera, seemetrix trial and Signage Enterprise account
