Visual vernacular is a form of art which combines Sign Language, mime, poetry and cinematographic techniques: long shots, close-ups, and panorama. The performer assumes the perspective of each character and aspects of the setting. That why the performer adopt role shifting between the subject and the object, shifting the different roles as the story goes along.
"The performer remains all the time within the film frame, so to speak, presenting a montage of cross-cuts and cutaway views" (Bernard Bragg)
