Abstract
A tactile recognition language display device includes at least one language communication segment. Each language communication segment includes a top portion having a tactilly recognizable language symbol and a side portion having a corresponding visually recognizable language symbol. The language communication segment further includes engaging members for mounting language communication segments to form words or phrases displaying a message, such as in a public place. The language communication segments of the tactile recognition language display device are removably mounted in such a way that the tactilly recognizable portion of the displayed message is easily accessible to touch by visually-impaired individuals while the visually recognizable portion of the displayed message is easily viewed. The language communication segments are removably mountable on a mounting board which may be moved to various locations for conveying the tactilly and visually recognizable message.
