Three prototypes (three w.i.p.) that try to explore the ways in which an AR mobile application can interact with a work of art having in mind the public, the researchers and the restorers:

1) A study on how augmented reality can help the comprehension off the geometric construction of the perspective in the holy Trinity fresco in the church of Santa Maria Novella in Florence Italy

2) A study about of augmented reality and the visualization of another series of frescos in the same church in Florence and the exceptional chapter house that contain them.

3) And the study about multispectral photography and AR on paintings and in the future for three-dimensional works of art.

  2. 2. AWE2014 AR for Cultural Heritage © Giovanni Landi giovannilandi@yahoo.it Three works in progress will be shown that explore the possible interactions between an AR mobile application and a work of art, using different datasets provided by researchers from different fields: •The HolyTrinity fresco (Masaccio, 1426) and the studies of Prof. M.T. Bartoli about linear perspective in the early renaissence. •The S.Maria Novella Chapter House (frescos by Andrea di Bonaiuto, 1355) and its Phase Shift 3d Laser Scan by Arch. Carlo Battini. • Panoramic Multispectral Imaging of Early 1900 Sicilian Devotional Art by Dr. Antonio Cosentino.

The image of the upper face of the cube stays between the sides of the triangle. The rear edge of the cube lies at 2/5 of the height of the isosceles triangle. The viewing angle is 68°.

  9. 9. AWE2014 AR for Cultural Heritage © Giovanni Landi giovannilandi@yahoo.it AR Application based on Unity and Vuforia 3D section: Users can explore a 3d complete reconstruction of HolyTrinity Perspective construction section: Users can follow step by step the geometric construction of the fresco’s perspective through intuitive outline animations showing the relations between 2d and 3d. In both sections the users is notified when he is staying in the exact position Masaccio chose as the point of view of his poerspective.
