“…This is especially challenging in collaborative scenarios, which pose still more technology and pedagogical difficulties. Augmented reality (AR) is a technology that may be used to connect physical and virtual spaces, as AR is based on the superposition of virtual objects in physical environments [2]. AR has also pedagogical affordances, such as the capability of enhancing spatial skills using 3D virtual objects, the potential positive impact on the engagement of students, and the scaffolding in learning (e.g., guiding students with AR).…”

Ubiquitous and mobile learning scenarios define activities happening within and beyond the walls of a classroom. However, the orchestration of authentic learning situations involving both physical and virtual spaces is still a significant challenge for teachers. Several proposals recently reported in the literature try to reduce teachers' orchestration burden by means of authoring tools, and usage of Augmented Reality technologies for connecting physical and virtual spaces. However, these proposals are restricted to specific technologies, pedagogies, or to a very limited range of activities. We present GLUEPS-AR, a system to aid teachers in the orchestration of across-spaces learning situations. With GLUEPS-AR, learning designs defined with multiple authoring tools can be deployed and managed at run-time throughout ubiquitous learning environments composed by different VLEs, Web 2.0 tools and AR applications. Thus, GLUEPS-AR allows multiple design and enactment technologies, and a wide range of learning activities, not restricted to a single pedagogy.

“…It is very well suited for improving position tracking for mixed reality applications, which particularly rely on fast update rates and highresolution tracking [27], [28], [29]. As a sourceless tracking modality that works both indoors and outdoors, it is a valuable supporting and enabling technology component for the long-term goal of Anywhere Augmentation, making mixed reality possible in unprepared environments without incurring high start-up costs.…”

Abstract-Anywhere Augmentation pursues the goal of lowering the initial investment of time and money necessary to participate in mixed reality work, bridging the gap between researchers in the field, and regular computer users. Our paper contributes to this goal by introducing the GroundCam, a cheap tracking modality with no significant setup necessary. By itself, the GroundCam provides high frequency and high resolution relative position information similar to an inertial navigation system but with significantly less drift. We present the design and implementation of the GroundCam, analyze the impact of several design and runtime factors on tracking accuracy and consider the implications of extending our GroundCam to different hardware configurations. Motivated by the performance analysis, we developed a hybrid tracker that couples the GroundCam with a wide area tracking modality via a complementary Kalman filter, resulting in a powerful base for indoor and outdoor mobile mixed reality work. To conclude, the performance of the hybrid tracker and its utility within mixed reality applications is discussed.

How to improve the efficiency of guiding disassembly sequence is the main research contents of augmented reality maintenance. To furnish the disassembly sequence to the system efficiently, assembly disassembly hybrid hierarchical graph model is established based on interference matrix between the assembly parts. The assembly's disassembly mathematical model is build and a newly fruit fly optimization algorithm combined with genetic algorithm is used to solve the best path. Finally, an example based on augmented reality guiding system is analyzed in detail to show that the method is appropriate and efficient, the method has offered guidance to the research of augmented reality disassembly guiding system.
