                          If your device is well configured, you should see messages like this on the device panel:
      
                    Optical distorsion
                      Stype communicates tracking data as well as optical deformations to Smode.
		  
                      In Stype's model, the optic deformations are calculated according to the size of the camera chip.
		  
                          You can find the size of the chip, directly in the
