Glad that worked for you! Yes, in general the closer and better lit your face is, the better your results will be. Zoom controls is an interesting idea, thanks for the suggestion!
If you can work without your glasses, or have contacts, that should improved eye tracking. Or, you could use the Eye Gaze behavior, enable the Mouse Input parameter and perform the eye gaze using your mouse. Most web cams are fixed lenses and don't offer zoom controls, but offering controls for the few that do is a great suggestion.
Hi Jim and thanks for taking the time to reply!
I do work without my glasses and it's without my glasses that I have the tracking problems. I eliminate any problem being caused by my glasses at the outset!
Tried the Eye Gaze settings and Face Settings too. I was expecting that if the light settings and distance setting remain stable in you working environment, then the Behavior settings wouldn't require constant changes? Just minor tweaks!?
Using the Mouse input seems to defeat the object... I can see in Post production, this could be useful to fine tune the finished piece, so I'm looking at improving the Face Tracking, before going down that road!
You're right.. web cams are fixed lens, but it's digital zoom and not optical that is applied. I know that optical is far superior, but for such short distance, as would be employed with this application, digital zoom would work fine. The upshot of this is that it wouldn't be applicable to just a few, as you say, but to all users of most, if not all webcams.
The optical zoom and exposure ability... would help with different working setups people are bound to have.
I'm sure if anyone could add these feature to a camera app, it would be Adobe!
