A graphing calculator is an absolute necessity in today’s high-school curricula, in higher education and for professionals. The Orion TI-84 Plus is the world’s first fully accessible handheld graphing calculator. Based on the popular TI-84 Plus model from Texas Instruments, the market-leader in calculators and educational technology, the Orion TI-84 Plus represents a breakthrough in STEM education for blind and visually-impaired students.

Since its functions are exactly the same as the TI-84 Plus, the Orion TI-84 Plus Talking Graphing Calculator is very easy for teachers to help with. A high-quality, synthesized voice announces each key and the answer on the display, providing a choice of speech rates, voices, etc.

The Orion TI-84 Plus Talking Graphing Calculator consists of a compact accessory that is attached to the top of the TI-84 Plus and enables someone who is visually impaired to interact with the TI-84 Plus using speech, audio, and haptic (vibration) feedback. High-quality synthesized speech reads out all textual and symbolic information on the LCD screen, as well as each key-press. Graphs can be explored using either spoken announcements or the unique SonoGraph audio and haptic feedback which provides multi-modal 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 Orion TI-84 Plus Talking Graphing Calculator is fully expandable with hardware accessories through a USB port and can also print or emboss graphs when connected to a printer or embosser.

A high-capacity rechargeable battery provides many hours of continuous operation and an AC adapter is included to charge it. An automatic power-off feature further extends battery life. The unit comes with high-quality stereo earphones, user manual in audio and digital form, and an AC adapter/charger. The unit can also be charged while connected to a computer’s USB port.
