Head Motion Tracking
General Knowledge – all you need to know before you start. Must read !
DelanClip uses 3 Infra-red LEDs and you won’t see any light when you plug it into the USB port!
The light emitted by IrLED is not visible to the human eye!
The picture on the right was taken with a standard phone camera, you can see the illumination on it as any camera can ‘see’ the IR light. That is why you need a PC webcam to track the three points. The black bit of film on the picture is to block daylight going through the camera eye to make it easier for use in bright rooms. The film allows IR light pass and the camera track the three spotlights. DelanClip does not need any drivers – USB plug is only to power the LEDs, the device is fitted with a PTC fuse which provides protection of your PC Motherboard from power surges.
Above video shows you how to start with mounting the DelanClip as well as how to setup the PS3 Eye camera for head tracking.
(please turn off any ad blocking software as this will hide the video)
It does not matter which side you attach it on… It is all down to the software you use. You can set the model position in FaceTrackNoir later. But it is often easier to just move your camera to be cantered with your clip position.
You do not need to set the model dimensions as the DelanClip has been manufactured to the default dimensions from the point tracker plugin.
Which one to choose?
It is always worth to trying any camera you actually have, before you go and buy another!
Please bear in mind, that the basic, unmodified cameras, never get the best performance when compared to 75 frames per second with PS3 Eye Camera.
This is the defining factor that is most important if you need very smooth movement translation into your favourite game.
There are many (recommended) cameras which will work great as a tracking receiver.
Make sure your antivirus software is disabled while you will be installing the camera driver !
When you get your camera you also need a driver. Follow this link or search online for: PS3 Eye camera drivers
Camera Check !
After installation of the drivers please make sure your camera is working as a normal device to use with applications, eg. Skype.
The Daylight Filter
If you have bought a set with the camera from us – you can skip this step as it’ll already be done for you!
Unmodified cameras: make sure you have already fitted the 2 pieces of the transparent coloured film enclosed with the DelanClip on the top of the lens of your camera.
If you use your own (modified) camera without an IR filter – it is recommended to use a bit of film from floppy disk drive.
This is built-in software delivered with the PS3 Eye camera PC drivers. You need to go to Menu and from DEVICES choose PS3 Eye Camera before you will be able to change anything. Then go to OPTIONS and click VIDEO CAPTURE FILTER to open the window; example in right side of this screenshot. Please use it to pre-set your camera threshold before you go to set up the threshold in FaceTrackNoIR. Please set your gain and exposure to get the results as similar to the video guide as you can.
Please note – if you are not satisfied with the LED dots size in your head tracking software you should remove the IR filter from your PS3 Eye camera. We do not guarantee perfect results untill you have dedicated and properly modified camera.
Bring your DelanClip to life! Choosing the software it is the second most important thing so let’s take a look!
Original source of files it here -> https://github.com/opentrack/opentrack/releases
Also a quick guide how to start is here: https://github.com/opentrack/opentrack/wiki/Quick-Start-Guide-(WIP)
I suggest to download STABLE (v2.2) version if the newest is not working properly.
DelanClip is also compatible with TrackIR cameras and software! If you used to have a TrackIR system with the reflecting 3 point bracket – DelanClip is the best replacement for it. You can use DelanClip in exchange of the TrackClip getting similar pro-level results as with TrackClipPro.
