Augmented reality is a rapidly advancing technology as it is widely used in several applications and domains, from the aerospace industry to medical-surgical applications, particularly in learning and training. A fundamental part of the educational use is the graphical user interface as a vehicle to deliver information to students. Within the augmented experiences development process, it is necessary to identify the most appropriate way to describe the user interface. This article evaluates languages describing augmented reality user interfaces. In this paper, several languages are analyzed, and new criteria are proposed to extend the evaluation framework. Finally, the results show the current limitations and the slowdown of development and adaptation of new languages for augmented reality platforms.

“…Similar web-based tools are also used for defining the geoposition of virtual content in location-based experiences [33] and for creating augmented reality presentations [17]. These tools sometimes define their own custom languages for content and the specification of rules [24,38], both of which are necessary for enabling more flexible interactions and storytelling (a particularly important focus in media production). To overcome the difficulty of manipulating tridimensional content using 2D user interfaces, other solutions have adopted simple content and interaction prototyping directly within augmented reality [8], either leveraging gestures [39] or tangible interfaces [21].…”

Figure 1: CAVE-AR is a virtual reality (VR) authoring tool aimed at assisting designers in creating, simulating and debugging augmented reality (AR) experiences. In the left image, a user in the real world is seeing AR content through his mobile device. On the right, a second user is able to monitor in real-time, through our authoring system, what the real-world user is seeing, and debug eventual faults. A dedicated panel displays hardware information about the user's mobile device (a), whose horizontal positioning accuracy is represented by a red circle (b). Two additional views display the estimated perspective of the user (c) and the live AR video feed from the device camera (d). ABSTRACTDespite advances in augmented reality (AR), the process of creating meaningful experiences with this technology is still extremely challenging. Due to different tracking implementations and hardware constraints, developing AR applications either requires low-level programming skills, or is done through specific authoring tools that largely sacrifice the possibility of customizing the AR experience. Existing development workflows also do not support previewing or simulating the AR experience, requiring a lengthy process of trial and error by which content creators deploy and physically test applications in each iteration. To mitigate these limitations, we propose CAVE-AR, a novel virtual reality system for authoring, simulating and debugging custom augmented reality experiences. Available both as a standalone or a plug-in tool, CAVE-AR is based on the concept of representing in the same global reference system both in AR content and tracking information, mixing geographical information, architectural features, and sensor data to simulate the context of an AR experience. Thanks to its novel abstraction of existing tracking technologies, CAVE-AR operates independently of users' devices, and integrates with existing programming tools to provide maximum flexibility. Our VR application provides designers with ways to create and modify an AR application, even while others are in the midst of using it. CAVE-AR further allows the designer to track how users are behav-*

“…In turn, multimedia content that can appear within the AR scene can be 2D images, 3D images, video sequences, sound sequences, text or embedded web pages. To enable free composition of AR scenes from arbitrary multimedia content, various scene templates encoded in the CARL (Contextual Augmented Reality Language) language are used [24,25].…”

Augmented reality enables superimposing various kinds of computer generated content, such as interactive 2D and 3D multimedia objects, in real time, directly on a view of real objects. One of the application domains, which can particularly benefit from the use of AR techniques, is education. However, to enable widespread use of AR in education, simple and intuitive methods of preparation of learning content are required. In this paper, we propose an easy-to-use method of augmenting printed books with arbitrary multimedia content. A popular Moodle-based educational platform has been extended with a plugin enabling creation of AR presentations. In addition, an associated mobile application is provided, which helps teachers assign the presentations to book pages and enables students to access the content.
