Thumb Braille

Thumb braille gives access to braille on a 12 key phone pad as well as most of the keys on a standard keyboard and entry only requires the two thumbs. Keys 1, 4 and 7 represent the braille dots 1, 2 and 3. Keys 3, 6 and 9 represent braille dots 4, 5 and 6. You can think of it as your left thumb being the left side of a Perkins Brailler, and your right thumb being the right side of a Perkins Brailler. The middle keys represent the combination of dots that would be hard to hit with one thumb. Key 2 represents dots 1 and 3, key 5 represents dots 1, 2 and 3, key 8 represents dots 4 and 6 and key 0 represents dots 4, 5 and 6. As an example, you could type the letter l by just pressing 5 instead of struggling to press 1, 4, and seven. You can also perform the modifier keys in thumb Braille. Pound acts as space, zero acts as control, and star acts as ALT. For more information on Thumb Braille,

ease of use

Despite some frequent thoughts, thumb braille is easy, and if you think about it, is logical. True, it is not like a standard Perkins keyboard, but when you look at a typed braille letter, you see that dots 1, 2, and 3 are on the left, and dots 4, 5, and 6 are on the right. So, when you are typing thumb braille, it is like typing how you read. The way you type is the way you read.
