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.

“…Drone projection is an emerging research topic in which researchers attempt to realize an autonomous projection system that provides SAR anywhere [10,11]. Because a drone on which a projector is mounted generally flies with fluctuations, the geometric registration parameters must be estimated in each frame.…”

Reliability of 638-nm broad area laser diode (LD) is basically dominated by catastrophic optical mirror degradation (COMD) at a front facet. The facet and window-mirror structure as a measure to COMD of 638-nm broad area triple emitter were revised to achieve highly-reliable operation under high output power. The improved LD showed very stable operation up to 5,000 hours under operation current of 4.9 A (initial output of 4.75 W), CW without any COMD failure, indicating that the mean time to failure due to COMD exceeding 8,100 hours under the condition. It was approximately 3.3 times of our former LD.

Indoor navigation with micro aerial vehicles (MAVs) is of growing importance nowadays. State of the art flight management controllers provide extensive interfaces for control and navigation, but most commonly aim for performing in outdoor navigation scenarios. Indoor navigation with MAVs is challenging, because of spatial constraints and lack of drift-free positioning systems like GPS. Instead, vision and/or inertial-based methods are used to localize the MAV against the environment. For educational purposes and moreover to test and develop such algorithms, since 2015 the so called droneSpace was established at the Institute of Computer Graphics and Vision at Graz University of Technology. It consists of a flight arena which is equipped with a highly accurate motion tracking system and further holds an extensive robotics framework for semi-autonomous MAV navigation. A core component of the droneSpace is a Scalable and Lightweight Indoornavigation MAV design, which we call the SLIM (A detailed description of the SLIM and related projects can be found at our website: https:// sites.google.com/view/w-a-isop/home/education/slim). It allows flexible vision-sensor setups and moreover provides interfaces to inject accurate pose measurements form external tracking sources to achieve stable indoor hover-flights. With this work we present capabilities of the framework and its flexibility, especially with regards to research and education at university level. We present use cases from research projects but also courses at the Graz University of Technology, whereas we discuss results and potential future work on the platform.
