A brailler is a device that writes braille by pressing raised dots into thick paper. It works like a typewriter, but instead of printing ink letters, it embosses patterns of dots that blind and visually impaired people read with their fingernails. The most widely used model, the Perkins Brailler, has been in production since 1951 and remains the standard tool for learning and writing braille worldwide.
How a Brailler Works
Every braille character is built from a cell of six possible dot positions, arranged in a grid of two columns and three rows. A brailler has six keys, one for each dot position, plus a spacebar in the center. The keys are laid out in a single row: dots 3, 2, and 1 sit to the left of the spacebar, and dots 4, 5, and 6 sit to the right. To form a letter, you press the correct combination of keys at the same time. The letter “a,” for example, is just dot 1. The letter “g” is dots 1, 2, 4, and 5 pressed simultaneously.
Alongside the six dot keys and spacebar, a brailler has a backspace key and a line advance key to move the paper forward. You feed a sheet of heavy paper into the machine, type your text, and pull out a page of raised dots. The paper needs to be thick enough to hold the embossed dots without tearing or flattening. The World Health Organization recommends braille paper weighing about 90 pounds (around 146 gsm), which is noticeably heavier than standard printer paper.
The Perkins Brailler
The Perkins Brailler is far and away the most common mechanical brailler. It was designed by David Abraham, a craftsman in the industrial arts department at Perkins School for the Blind in Massachusetts. When Abraham started work in the mid-1930s, existing braille writers were noisy, expensive, and broke down constantly. The first braille writer had been introduced back in 1892 by Frank Hall, superintendent of the Illinois School for the Blind, and the basic design hadn’t improved much in the decades since.
Abraham’s redesign, unveiled to the public in 1951, was a leap forward. It was tough, hard to break, and had a light enough touch that young children and people with limited finger strength could use it. More than 375,000 Perkins Braillers have been distributed to students, educators, and families around the world. A new one currently costs $810, and Perkins guarantees each unit for one year, though the machines are built to last decades with basic upkeep.
Mechanical vs. Electronic Braillers
Mechanical braillers like the classic Perkins model are purely analog. You press keys, metal pins push dots into paper, and that’s it. There’s no screen, no battery, and nothing to charge. This simplicity is a strength: the machines are extremely durable and intuitive to learn. The trade-off is that you can’t hear what you’ve typed (unless you read the dots by touch), and there’s no way to save or transfer your work digitally.
Electronic braillers add modern features on top of the same basic key layout. The Mountbatten Brailler, for instance, is an electronic braille writer with audio support for all its operations, file storage, and computer connectivity. It was designed especially for early braille instruction, giving young learners spoken feedback as they type. The APH SMART Brailler takes a different approach by combining a mechanical brailler with a 4-inch color screen and a speaker. As you type on the keys, the screen shows both simulated braille dots and large print, while text-to-speech reads the characters aloud. It also has a USB port for saving and transferring documents. These features make electronic braillers especially useful in classrooms where sighted teachers are helping blind students learn, since both can follow along in their preferred format.
How Braillers Are Used
The most common use of braillers in the United States is teaching braille. Many young students learn to read and write braille on a Perkins Brailler before moving on to more advanced technology like refreshable braille displays or screen readers. For adults, braillers serve as a quick, reliable way to jot down notes, label items, or write personal documents.
A brailler is distinct from a braille embosser, which is essentially a printer. An embosser connects to a computer and translates digital text files into embossed braille pages at high speed. You wouldn’t sit down and compose a letter on an embosser the way you would on a brailler. The brailler is the hands-on writing tool; the embosser is for producing bulk output. There’s also the slate and stylus, an even simpler option. It’s a small metal or plastic frame that holds the paper while you punch individual dots by hand with a pointed stylus. Think of it as the braille equivalent of a pen and notepad: portable, affordable, and useful for quick notes, but slower and more physically demanding than a brailler for longer writing.
Maintaining a Brailler
A Perkins Brailler contains over 700 individual parts, so serious repairs should be handled by a certified technician. But routine cleaning is something you can do yourself, and it keeps the machine running smoothly for years. How often you need to clean depends on use: once a year for light use (a few hours a week), every other year for daily use like in a school setting, and every three years for very heavy use of more than an hour a day. That schedule might seem counterintuitive, but heavier use actually keeps the internal parts moving and less prone to buildup.
The cleaning process takes one to two hours and involves a Phillips screwdriver, a wire brush, lint-free cloth, isopropyl alcohol, specialized brailler oil, and lubricating grease. Perkins provides step-by-step printed guides in English, Arabic, Hindi, and Simplified Chinese, along with a 26-minute instructional video. The school also offers free cleaning kits with enough supplies for three cleanings.
