The Orion TI-84 Plus Talking Graphing Calculator is an innovative marriage of
traditional, dependable technology and innovative accessibility. The design goal and
driving force for Orbit Research and the American Printing House for the Blind (APH) in
the development of the Orion TI-84 Plus was simple - make the TI-84, one of the most
popular graphing calculators in schools, accessible for students who are blind or who
benefit from auditory feedback. To do this, we had to design and add a small extension,
called the Orion, to the TI-84.
