Claim 26:
27. The method of claim 15, wherein further comprising determining the reference focussing distance corresponding to the wavelength of light provided by the at least one light source by one of:
executing a calibration process wherein a user of the at least one controller is instructed to move the at least one controller with respect to the at least one camera until the at least one light source of the at least one controller is in-focus in a calibration image captured during such moving, a distance of the at least one light source from the at least one camera at a time of capturing said calibration image being determined as the reference focussing distance corresponding to the wavelength of light emitted by the at least one light source; or
calculating the reference focussing distance corresponding to the wavelength of light emitted by the at least one light source using at least one mathematical formula.
