A method for communicating graphic data such as plotted two-dimensional curves to a user such as a sight impaired person is disclosed. The disclosed arrangement uses haptic or tactile stimulation of a user's extremity such as is relied--upon in the Braille code fingertip communication already known to many sight impaired persons. Computerized control over a Braille character-like display and use of the computer mouse as a data selection input device; are included in the invention. The invention also includes provision of data enhancement and data interpretation aids including axis names, multiple curve identifications, grid line identifications and the addition of audio information such as tick sounds and spoken utterances to supplement the tactile communication. A computer-based embodiment of the invention is disclosed, this in the form of hardware block diagrams, software flow diagrams and computer code listing, the latter being primarily in microfiche appendix form.
