The CrowdSight SDK is designed for use with digital signage displays which, when fitted with a standard USB web camera, can start recording and analysing the faces of those who pass by and look at the screen.

ThirdSight says its technology can determine the age, gender and mood of the person looking at a screen, and gives screen owners the ability to adjust the information or media displayed based on the viewer’s characteristics.

Other metrics collected by CrowdSight include total foot traffic, attention time, head pose, clothing style and colours, and repeat viewers.
