Strange face illusion with two-way Mirror feedback


A version of the Strange Face illusion with video feedback and face tracking through a two-way mirror

“… a quiet room dimly lit by a 25 W incandescent light. The lamp was placed on the floor behind the observer so that it was not visible either directly or in the mirror. A relatively large mirror (0.5 m60.5 m) was placed about 0.4 m in front of the observer. The luminance of the reflected face image within the mirror was about 0.2 cd mÿ2 and this level allowed detailed perception of fine face traits but attenuated colour perception…The task of the observer was to gaze at his/her reflected face within the mirror. Usually, after less than a minute, the observer began to perceive the strange-face illusion…”  Giovanni B Caputo, Perception, 2010, volume 39, pages 1007 – 1008 2010
