Projection-Based Augmented Reality

In this seminar report a branch of augmented reality (AR), namely, projection-based augmented reality (projected AR) is discussed. To do so four different projected AR systems are presented: Virtual Showcase, iLamp, RoomProjector and SLAMProjector. By a comparison between projected AR and hand-held seethrough displays, which have become common through the success of tablets and smart phones, it becomes apparent that these technologies well complement each other. Motivated by the question of what is needed to make a projector mobile, the presentation order of the devices is chosen with respect to their level of mobility. In this way, it is possible to illustrate how a device needs to fulfil one or more requirement to be able to work at a certain level of mobility. Thereby, the main requirements are:
