Abstract
A mapping system that integrates tactile language (specifically level 1 Braille) with the visual alphanumeric alphabet. A unified tacto-visual form of communication and recording is created. Alphanumeric characters present simultaneous direct relationships between the individual alphanumeric elements and their tactile corollaries within a single form. Segments of each alphanumeric character are configured to meet at points of tactility. Tacto-visual characters comprised of two languages (i.e. Level 1 Braille and the visual alphanumeric character set) are created. Configurations of characters create a legible and readable simultaneous form of communication. The invention provides a tactile surface for blind readers to engage with a visual source for full vision readers and a hybrid for low vision readers. Tactile communication can occupy a same location as the alphanumeric visual communication thereby providing an interface for both the visually-impaired and the full-vision user.
