Talking Graphing Calculator

  • $ 975.00

The Orion TI-84 Plus Talking Graphing Calculator is a modified TI-84 Plus with a small attachment that adds accessibility and additional controls. APH partnered with Orbit Research® and Texas Instruments® to make this powerful calculator accessible.

Unique Graph Access

The attachment consists of a unit on top of the calculator, above the screen. It includes six function keys and five cursor keys, plus stereo speakers. Use the function keys to control preferences, volume, rate, pause, silence, repeat, and more. Use the cursor keys for screen reader control, such as previous and next line, next word, next character, read all, etc.

Explore graphs using either spoken announcements or innovative “sonograph” audio and haptic (vibrating) feedback. For audio feedback, moving along the graph from left to right shifts the tone from the left to the right stereo channel; raises and lowers the tone to follow graph coordinates; as the graph moves below the x-axis where the y-coordinates are negative, white noise is added to the tone. Haptic feedback is provided for negative y-coordinates, axes crossings, and tick marks.
