Kyd has been struck more than once by the acuity of Everyman's blind patrons, who can discern from the sound of footsteps how fast the person is moving, how much he weighs, and what mood he's in.
For instance, Maurice Peret, a staff member for Blind Industries, took part in the touch tour two days after attending the madcap comedy at Everyman.
He said there's a misperception that blind people don't pick up on facial expressions and body language, even in the case of an actor standing on a stage 50 feet from the audience.
"The only way I can explain it is that I see differently than you do," said Peret, 47, of Baltimore. "I process information through a different system.
"If someone points in a particular direction, he'll usually turn his head, and the volume of his voice will be different. A disapproving look is very easy to read. I can hear a smile or a frown because the shape of the person's mouth changes. I can hear a slight tilt of the head, or if a person slumps and looks down toward the ground.
"It gives me what I believe to be a full experience of the play."
