Abstract: Learning objects are used in many knowledge areas and may be aligned with technologies such as stereoscopy and ultra-high definition, instigating interactions and arousing interest in educational environments. Gener- ating such objects from real pieces is a challenge because it requires computational resources to maintain quality and fidelity. Another challenge is to port these objects to different devices such as immersive theater, cell phones, virtual reality glasses, and televisions/projectors. Hence, we developed a framework capable of generating learning objects from real pieces with quality and fidelity of form, color, and texture. This article focuses on the generation of learning objects for these devices. 1 INTRODUCTION In a teaching-learning process, the teacher can deploy elements that aim to arouse the students’ interest re- gardless of their nature such as rocks, leaves, animals, videos, images, etc. These elements enrich the pro- cess by putting the students in contact with objects that bring learning closer to their reality. However, not all of these elements are easily ac- cessible to the teacher, although representations may be used to introduce them to the learners. Some of these elements may be seen as Learning Objects (LO), which, according to the Learning Technology Stan- dards Committee (LTSC-IEEE), ”Learning Objects are defined here as any entity, digital or non-digital, which can be used, re-used or referenced during tech- nology supported learning” 1 . However, there is no consensus on this definition, as seen in (Wiley, 2002). Interactivity, high resolution, stereoscopy, aug- mented reality and three-dimensional projection are present in movie theaters, advertising, televisions and cell phones. These techniques are available and may be used to support the teaching-learning process as a way of presenting and manipulating LOs. LOs need environments and repositories to be shared, as discussed in (Santiago and Raabe, 2010; Freire and Fern´ andez-Manj´ on, 2016). There are LOs (Sinclair 1 LTSC - http://grouper.ieee.org/groups/ltsc/wg12/ et al., 2013) that can be used multidisciplinarily, some can be customized(M´ endez et al., 2016; Garrido and Onaindia, 2013). LOs can be evaluated by indicators themselves (Sanz-Rodriguez et al., 2010). In order to create LOs compatible with these tech- niques, we developed a framework composed of a Full Frame Semi-spherical Scanner(F2S2) and pro- cessing software. The F2S2 digitizes, through pho- tography, all the angles of an object, forming a hemisphere with these images; hence the term semi- spherical (Section 2). The terms full frame refer to the fact that each image represents the whole object for that viewing angle, unlike other technologies, such as the laser scanner that digitizes the object into parts to later reconstruct a given view. The LO consists of photos and navigation software, which allows for interactive visualization, i.e., you can visualize and manipulate the object from any desired angle. You can associate points of interest with hypermedia. For example, in a History class, one could pick up an ar- chaeological object that, by its rarity, cannot be ma- nipulated by the students. This piece can be scanned for Ultra High Definition (UHD) presentation, allow- ing for magnification and movement, showing details that even the naked eye would not see. Explanatory content (hypermedia) may be added at the teacher’s points of interest to enrich knowledge. Figure 1 shows an example of a LO in UHD and with hypermedia. Characteristic for LOs generated by F2S2 is that Roberto Olsen, D., de Almeida e Silva, F., Murbach Pierin, L., Hornung Moraes, A. and José Rodrigues Justino, E.
