Talking Graphing Calculator

Talking graphing calculator

Orbit Research and the American Printing House for the Blind (APH) have teamed up to introduce the Orion TI-84 Plus, the world's first fully accessible handheld graphing calculator.

The Orion TI-84 Plus consists of a compact accessory that is attached to the top of the TI-84 Plus and enables a user who is visually impaired to interact with the TI-84 Plus using speech, audio, and haptic (vibration) feedback. All textual and symbolic information on the screen, as well as each key-press is spoken using high-quality synthesized speech. Most importantly, graphs can be explored using either spoken announcements or the SonoGraph™ audio and haptic feedback. The user can also review the contents of the screen at any time, including all text and graphical information, without affecting the calculation.

The unit is fully expandable with hardware accessories through a USB port and can also print or emboss graphs when connected to a printer or braille embosser.

The Orion TI-84 Plus will be available through APH's Federal Quota Program and units will ship in time for the 2013-2014 school year.
