Tra illusione e realtà - Università degli Studi di Sassari

CONVEGNO: Illusione e Realtà: tra Psicologia e Neuroscienze
Martedì, 12 luglio 2016 - h. 15:00 - 19:00 - Aula Magna, Piazza Università - Sassari
Il convegno è preceduto dalla conferenza stampa a cura del Magnifico Rettore, prof. Massimo
Carpinelli, e del Direttore del Dumas, prof. Gavino Mariotti, sul nuovo corso di laurea in Scienze e
Tecniche Psicologiche dei Processi Cognitivi (Classe L-24)
(https://www.uniss.it/ugov/degree/4772) recentemente approvato dal Ministero. Il convegno
rappresenta la prima iniziativa culturale del nuovo corso di laurea rivolta alle future matricole e a tutti gli
studiosi e studenti interessati.

Abstract della relazione al convegno:
The term “impossible objects” were initially used to refer to impressions of 3D structures that are
evoked by 2D pictures but that cannot exist. They are popular in that Dutch artist Escher used as
elements for his artworks. Later, several methods have been discovered for constructing them as actual
3D objects, and they gave a new genre of optical illusion. I myself found one of such methods in my
research on machine interpretation of line drawings. On the basis of this method, I also found several
new classes of impossible objects. They might be classified into five generations: (1) anomalous
objects, which appear to be 3D realization of impossible objects, (2) impossible motion objects, which
appear to create motion that defies physical law such as the gravity law, (3) ambiguous cylinders,
whose appearances change drastically in a mirror, (4) partly invisible objects, which partly disappear in
a mirror, and (5) topology disturbing objects, which change topological property in a mirror. I will show
them in the order I found together with their mathematical background. Optical illusion created by those
impossible objects reveals fragility of human vision systems, and raise new research problems on how
the humans perceive 3D structures, and why they acquire those abilities.
