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.

The compact accessory that is attached to the top of the TI-84 Plus enables someone who is visually impaired to interact with the TI-84 Plus using speech, audio, and haptic (vibration) feedback. Graphs can be explored using either spoken announcements or the unique SonoGraph audio and haptic feedback which provides multi-modal visualization of graphs. The user can also review the contents of the screen at any time— including all text and graphical information— without affecting the calculation or losing their place. It is fully expandable with hardware accessories through a USB port and can also connect to your computer via USB cable to print or emboss graphs and other work (requires a printer or embosser).
