Research Interests

La ricerca del gruppo si focalizza principalmente sulla Computer Grafica (CG) e sull'Interazione Persona-Macchina (HCI). Il prof. Riccardo Scateni, che ha fondato il gruppo nel 2007, guida la ricerca nel campo della Computer Grafica, mentre il prof. Davide Spano, che è entrato a far parte del gruppo nel 2012, conduce la ricerca in HCI.
Ultimamente, i temi di ricerca affrontati sono i seguenti: 

• Computer Graphics and Geometry Processing 
• Digital Fabrication
• End-User Development per la realtà estesa
• Interazione Uomo Macchina applicata alla prototipazione di sistemi interattivi
• Surface and Volumetric mesh generation and optimization
• XR - Realtà Estesa (AR,VR,MR)
• eXplainable Artificial Intelligence (XAI)
