This distributed model has proved to be helpful in accelerating the perception of what occurred, where it happened, and who needed help in recent disasters such as the Boston Marathon bombs, the Oklahoma tornado or the Central Europe floods. Nevertheless, this kind of sources might provide unreliable, partial, ambiguous and inconsistent information that do not necessarily help to understand the situation. An alternative may be the combination of crowdsourcing activities and more official flows of information to make up a coherent big picture that support the needs of decision makers. This paper introduces a software approach conceived to convey stories created from different sources –official and unofficial- as a way of depicting situations in a collaborative manner.

Users get immersed into the visualization and interact with the bubbles using gestures with a view to overcoming some limitations of 2D visualizations due to the capabilities and interaction affordances of the devices. The technological advances in VR give the possibility to design malleable and extensible representations and more natural and engaging interactions. Using the Oculus Touch controllers, the users can grab and move the bubbles, throw them away or bump two of them for creating a cluster. We have tested the Immersive Bubble Chart with the hierarchical clusters of semantically related terms generated from Twitter.

Each expert has a view of the system and she uses domain specific languages in order to express solutions to the problems she is concerned with. In this way, the final system can be seen as a combination of a number of complementary views, each of which focuses on problems of a different nature. However, such views are expressed with different specification tools so that they have to be integrated to produce a common design that is complete and consistent. Creating a common language encompassing multi-disciplinary design views is a challenging endeavor but it might impose a cognitive overload to each member of the group who is exposed to unfamiliar concepts of other disciplines in her design view. Alternatively, this paper describes an approach called MODUWEB that consists of letting each designer use the tool she is proficient in for her de...

The game has been designed and implemented with the aim of investigating the potential outcomes and benefits of educational AR games for Head Mounted Displays (HMDs). This type of devices allows the user to interact with the virtual objects with her own hands. Also, they support a wide range of view of the augmented world and, in general, a more immersive experience that the one obtained when using AR based on mobile devices. Although in theory they provide an ideal mean to deliver AR educational games, the evidence on the benefits obtained from these experiences when compared with standard mobile-based AR technology has not been sufficiently investigated. In this work we present two versions of the game designed for the two versions of the HoloLens 1 and 2, respectively. Each version of the game has been designed with the aim to exploit the interaction capabilities afforded by each HMD. We also present the results of an informal evaluation of the game version for the HoloLens 1, which allowed to disclose some limitations and problems that users experienced when using the technology.

Instructional designers have to balance the cost associated with the development of these virtual environments with the expected outcomes reported by the use of the new technology, but for some types of learning processes those outcomes are not always easily predicted. In this document the authors experience using 3D Virtual Worlds is summarized with the aim of getting a deeper understanding of their potential pedagogical use when supporting two different types of learning activities commonly included on a course: direct instruction, which exploits the social dimension of the technology, and individual learning activities in which that feature is not used. Based on those experiences a set of guidelines for designing 3D vi...
