Abstract
Augmented Reality (AR) and Mixed Reality (MR) applications require the combination of synthetic images with the real world. In some cases the real world images are acquired by an image sensor that is then combined with synthetic images and presented to the user to enhance the immersive experience. In the current state of the art, the displays are often mobile phone screens or some smart glasses. As an alternative, we propose to augment the world by projecting synthetic images on real surfaces. To do so effectively, virtual scenes must be properly rendered to match the tilt and position information of the projector which can be acquired from a multitude of sensors. One benefit of this type of AR it that the experience is not only lived by the person holding the projector, but for the people at the surroundings as well. So, a group of people can be aware of the augmentation, leading to a full range of new applications.
