Wall and Window Cultures
Wall and window cultures (originally Door and Window) are a metaphor which is referred to two cultures or behaviors of hearing and eyeing people how they and their world interact in different ways. Wall, or originally door, is an illustration of hearing people who can talk to each other through doors but cannot see each other. Window culture is a figure that eyeing people can talk to each other in visual-manual or sign language through windows that hearing people cannot hear well through windows.
