Visage Technologies very actively develops accurate face-tracking solutions. We are trying to keep up, by adding their latest version(s) to FaceTrackNoIR. The new version is scheduled to be released in April 2016.
If you have questions regarding Visage, please post them here: [discussion:visage]
Tracking facial features instead of IR-leds offers a great advantage: no hardware but a simple web-cam is required! So anyone can use the Visage Tracker, almost instantly.
The engine state displays the current status of the faceAPI engine and can be one of the following:
Using the Enable axis checkboxes each of the 6 DOF's can be enabled or disabled. Disabled means, that the output value will not be sent to FaceTrackNoIR.
Lighting and web-cam need to be good.
The current version is configured by settings in the file "Head Tracker.cfg" in the Visage folder of FaceTrackNoIR. The most relevant settings for users may be "camera_device", which enables selection of the video-source. If your webcam is not "the first" in the video-input order, then the value of 0 can be changed into 1 (or higher).
