- Abstract (EN)
- Following recent social trends and technological advancements we can expect a future, where more humans willingly merge their bodies with different forms of technology. Anticipating this trend, fundamental research on design, functionality and perception is required. Virtual simulations promise to be a viable tool to aid in such research, as they can simulate infeasible or impossible to manufacture devices and thus circumvent current technological limitations. Mixed Reality provides a well-established framework for realizing such applications, as it eliminates the requirement of simulating complex nuances of real-world environments. Instead, the simulation can be superimposed onto the user's surroundings. However, for a convincing blending of virtual bionic devices and the user's body a prior partial removal or concealing of the real-life body part is required -- a process called Diminished Reality. In interactive scenarios, this problem poses a significant challenge in the field of computer graphics. This dissertation first introduces TechnoSapiens, an interactive system that can replace the user's arm with a virtual bionic prosthesis in an Augmented Reality environment in real-time using DR approaches. The system is then extended to provide multi-sensory feedback to the user, including visual and haptic stimuli. Furthermore, the system can be distributed to a co-located, cooperative multi-user environment. In a series of evaluation and user studies, the effectiveness of the system for the purpose of simulating believable and convincing body augmentations is demonstrated. Applied to a cooperative multi-user environment, we show that the combination of DR and AR challenges the current understanding of established concepts related to perception in Virtual and Mixed Reality.
