Orion TI-84 Plus Talking Graphing Calculator
The TI-84 Plus is a powerful graphing calculator, but if you can't see the screen, this places you at a significant disadvantage at school and at work. Orbit Research and the American Printing House for the Blind (APH) set out to address this problem. Their adaptation of the TI-84 Plus is called Orion.
Orion adds speech, sounds, vibration, and navigational buttons to the calculator. We were happy to be part of the Orion journey. In addition to helping test the accessible TI-84 Plus Talking Graphing Calculator, PAC advised on aspects of how to sonify graphs, translate a field-based text interface into speech, and use haptics to help with the exploration of graphs and datasets.
