Date: June 2015 Source: 2015 12th Conference on Computer and Robot Vision (CRV) Proceedings (p 230 – 236), Halifax, Canada. Abstract: In tele-presence systems, direct face-to-face contact, is essential for emotional communication as it carries non-verbal clues. In commercial products, face-to-face contact is approximated by using either a large semi-transparent mirror to project an image…
