There are electronic devices on the market today that provide a tactile overview of different digital images, such as graphs. Rather than having a single line, like a regular braille display, these devices have a multi-line display, typically with around 60×40 refreshable pins. This allows different digital images, including graphs and text, to be tactilely displayed.
As these products are designed for a very niche audience, their prices are extremely high compared to products designed for a wider market. As a result, schools often cannot afford to provide these devices to the braille readers. However, you can visit the websites of various companies to find out more about how these devices work and what they can do. Some brands available on the market today include Orbit Graphiti, DotPad, and The Monarch.
