The HumanWare Mantis Q40 is a unique, all-in-one device that combines a full-size QWERTY keyboard with a built-in, refreshable 40-cell Braille display — letting you type like on a standard laptop while reading Braille output at the same time. It connects via Bluetooth (up to 5 devices simultaneously) or USB, making it versatile for use with computers, smartphones, or tablets — but it also works as a standalone Braille notetaker and reader thanks to onboard software for editing, reading books, and file management. Lightweight and portable enough to fit into a laptop bag, the Mantis Q40 offers a 40-cell refreshable Braille line beneath the keyboard that updates in real time as you type or read — enabling smooth Braille input/output without needing separate devices.
