Braillenäytöille

Braillenäytöille, commonly referred to as refreshable braille displays, are electronic devices that allow visually impaired individuals to read text displayed on a computer or other electronic device. These devices convert digital text into braille characters that are raised on a surface, allowing users to tactilely read the information. They typically consist of a series of braille cells, each containing pins that can be raised or lowered to form braille dots. The number of braille cells can vary, with common configurations ranging from 14 to 80 cells.

Braille displays connect to computers, smartphones, and tablets via USB, Bluetooth, or other wireless protocols. Software, often called a screen reader, intercepts the digital information and sends it to the braille display. This enables users to navigate operating systems, browse the internet, write documents, and interact with various applications. Braille displays are essential tools for education, employment, and daily life for many blind and visually impaired people, providing access to information that would otherwise be inaccessible. They often include navigation keys and routing buttons for easier control and interaction with the device.
