“…The authors of [19] used an AR system to detect thermal leaks by providing visual data to avoid common accidents in the workplace; similarly, the projector unit headed towards the area of interest. For educational purposes, a famous example of using AR is the interactive board in classrooms [20], where it helps students to become more involved in the in-class activity and increase their attention. However, the projection-based interactive board usually suffers from tracking sensor occlusion and the projection beam's blockage problems.…”

“…The user is fully involved in the projection process to customize the projected screen's size and location; on the other hand, several systems remove this facility from the user by restricting the interaction area to a specific location and size due to the pre-setup requirements [10,15]. Some conventional projection-based interactive AR systems cannot serve for applications that demand extended indoor interactive spaces, flexible assigning for the interactive areas, and larger user's interactive envelope [20][21][22]. Nevertheless, thanks to our system's mobility and customization capability, normal indoor spaces can support diverse interactive tasks.…”

With the rapid development of interactive technology, creating systems that allow users to define their interactive envelope freely and provide multi-interactive modalities is important to build up an intuitive interactive space. We present an indoor interactive system where a human can customize and interact through a projected screen utilizing the surrounding surfaces. An ultra-wideband (UWB) wireless sensor network was used to assist human-centered interaction design and navigate the self-actuated projector platform. We developed a UWB-based calibration algorithm to facilitate the interaction with the customized projected screens, where a hand-held input device was designed to perform mid-air interactive functions. Sixteen participants were recruited to evaluate the system performance. A prototype level implementation was tested inside a simulated museum environment, where a self-actuated projector provides interactive explanatory content for the on-display artifacts under the user’s command. Our results depict the applicability to designate the interactive screen efficiently indoors and interact with the augmented content with reasonable accuracy and relatively low workload. Our findings also provide valuable user experience information regarding the design of mobile and projection-based augmented reality systems, with the ability to overcome the limitations of other conventional techniques.
