Enhancing Projection-based Augmented Reality (Research)

Extended Reality (XR) encompasses Augmented Reality (AR), Mixed Reality (MR), and Virtual Reality (VR). Augmented Reality is a rapidly emerging technology that enriches the physical world with virtual objects. This doctoral thesis explores the possibilities of projection-based AR. This technology offers distinct advantages, such as eliminating the need for users to wear heavy headsets, making it more comfortable for extended use. Beyond user comfort, this research will try to improve projection-based AR by studying the portability, scalability, and applications of such systems. This thesis aims to research a portable/mobile system a user may employ to augment their environment exactly where they want the augmentation. Examples of such systems include a handheld smart flashlight and smart desk lamp. Many current solutions rely on static projectors. In those cases, the projection is limited to the field of view of the projector, which limits the adaptability to dynamic environments. Two main technologies required to create such a system are large-area tracking and projector-camera calibration. These methods directly impact the accuracy of the projections. In AR applications, precise accuracy is critical for seamless integration with the physical environment, unlike VR where the virtual environment is mostly self-contained. Most of the technologies that will be developed throughout this doctoral thesis are not limited to AR only but apply to XR in general.
