This research line has been one of the main areas of GRETEL in the previous period (2014-2016). Focused on the research on how new interactive visualization technologies allow the acquisition of skills and abilities faster and better than with traditional systems, the group's activity has been applied on two regional projects and in its own projects. In this line, the group has created a high rate of scientific acceptance and interest, especially in areas such as Architecture, where previous work is scarce. The objectives of the group for the new period are focused on incorporating in an effective, efficient, satisfactory (in line with the ISO-9241-11 usability standard), and motivating way new devices that allow students, regardless of their profile and characteristics, a better understanding of three-dimensional space. These skills are not exclusive to studies such as Architecture, Multimedia or Animation, but in a highly audio-visual current society they are fundamental for any user, whether or not they are in a training setting.

Drs. Villagrasa and Navarro have read their doctoral theses in this field (2016 and 2017), in which they are educational experts and are still working nowadays. The objectives of the new period focus on working with 3D rendering systems both physical (using 3D printing) and digital (using Augmented and Virtual Reality with Oculus, HTC or CardBoards devices, which are much more accessible), and hybrids (work with Data in different formats that are juxtaposed in the same representational level: AR / VR and 360 images and videos). Teaching, practicing with 3D models and locations, and with interactive/hybrid systems are basic skills that educators and students need to have mastered. Using PBL approaches and ending with the use of a wide range of technologies, such as mobile and wearable devices, tabletop System technology and video game engines that optimize the rendering and visualization of 3D space. In this field, one of the objectives of the group is to continue with the current project funded by the Ministry of Education and Competitiveness (2016-2020) and continue increasing the scientific production (especially in the field of Architecture studies). In addition, we are designing the creation of a Laboratory in two contexts (virtual and face-to-face) for the teaching and practice of subjects using these technologies and that enable to measure the student's experience.
