Moreover, the usual  precarious state of conservation of these artefacts, often with damaged  or missing areas, makes it difficult to perceive their original  aesthetic value. To overcome these limitations, we propose an  application of augmented reality able to support the observer in two  ways: first, the application completes the missing surface of the mosaic  or pavement by integrating the existent surface with a virtual  reconstruction; second, it enables the analysis of the geometric pattern  of the mosaic\/pavement by overlaying virtual lines and geometric  figures in order to explicit its geometric arrangements. The result is  achieved via a custom Android application able to recognize and track  the mosaic figure pattern and extra marker board, obtaining in that way a  coordinate system used to render in real-time the reconstruction of the  mosaic. Such rendering is overlaid to the video stream of the real  scene. The application runs on a standard smartphone embedded in a  Google Cardboard-compatible viewer and therefore is extremely  affordable. As a case study, in order to reconstruct its aspects and to  analyse its geometric pattern, we chose the roman mosaic re-found in  Savignano sul Panaro (near Modena, Italy) in 2011, after 115 years from  its first discovery, which is preserved less than half of its original  4.5 x 6.9 m surface.<\/p>\n\n\n","protected":false},"excerpt":{"rendered":"<p>https:\/\/iopscience.iop.org\/article\/10.1088\/1757-899X\/364\/1\/012094\/meta The visualization and analysis of mosaics and pavements are often compromised by their large sizes, which do not enable the observer to perceive their whole arrangement or to focus on details placed in farthest areas from its boundaries.
