1. A display device for use in displaying an augmented reality image of a real-world view or a virtual reality image to a user, the display device comprising:
an optical waveguide having an input optical element for receiving an image;
a projector for generating the image, the projector being physically coupled to the optical waveguide; and
a projector housing containing at least some components of the projector, the projector housing being moveable with respect to the optical waveguide, the projector housing containing the at least some components of the projector so that the image generated by the projector is fixed relative to the projector housing,
the projector including an image processor to correct the image generated by the projector and received by the input optical element of the optical waveguide dependent on a position of the projector housing relative to the optical waveguide.
