OKAO Module

The OKAO module works in real time and analyses images from a web camera and passes the information to the Perception module. The extracted information relate to the position of the user(s) in relation to the camera, their head rotation, eye gaze information, facial expressions and smile estimation. This module also calculates user’s gaze based on head and eyes direction and outputs the information to the perception module. This module was developed using C++ and uses pipes to communicate with the Perception module.

The OKAO module can only be used with the Perception module as its capable of interpreting the incoming data from OKAO. It has been used in multiple studies to capture users’ expressions from a web camera.
