Tech Tips

Welcome to our Technology Tips section! The NFB Jernigan Institute Access Technology team is always on the lookout for new and better ways to give blind people access to technology, as the ever-growing International Braille and Technology Center attests. In these tips we want to share some of the pointers manufacturers and developers share with us to help you learn about new applications and new programs, and to help you find new functionality in familiar products. The Access Technology team works with the relevant manufacturers and developers to obtain the tips listed here, to make sure that you get the best and latest about anything new in the world of non-visual access technology.


If you have any feedback on the tips, please contact Clara Van Gerven at [email protected].

Tips on how to use ACE Plus

ACE Plus is the latest personal multifunctional assistant from ABISEE.  It scans and reads printed materials out loud, and it saves OCR-converted text on its internal hard drive or on a USB flash drive.  It does this quickly and accurately. It also alerts you when a scheduled activity is due, enables you to send and receive emails, downloads ebooks, stores your photo album to share with friends and family and wakes you up when your alarm clock is set. Here are some tips on how to get the maximum from the device.

Tip 1. Short cut to Scanning and Reading

Place a printed page alongside the base of the device, so that ACE Plus captures the entire 8.5 by 11 inch space. No matter where you were in the Main menu previously, just press the Scan button and enjoy listening to the content of the page.

Math in Desire2Learn

Having math in an accessible format can be tricky, making it hard to interpret the math when students can’t even be sure that they’re getting the right message. The old way of dealing with mathematical equations was to create an image of the equation. Of course, this meant it was up to the instructor to create meaningful, unambiguous alt text for each equation. I think we all know that everybody’s idea of good alt text varies wildly, and we definitely all know how unforgiving math is about interpretations of equations. There is only one right answer.

Nemeth Code on the Braille Sense!

As of version 8.1 of the BrailleSense firmware, full Nemeth Support is available on the Braille Sense Plus, OnHand, and U2 series.

On Braille keyboard models, press BACKSPACE+N to enter and exit Nemeth Mode.
On QWERTY models, press ALT+N to enter Nemeth Mode. When in Nemeth Mode on QWERTY units, use Home row keys to write in Nemeth so that FDS are dots 123, and JKL are dots 456.

If you save your file as a DOC file and, unlike other products, it can print with standard mathematical symbols from a computer.

A Desire2Tame The Desire2Learn WYSIWYG Editor

At Desire2Learn, we care about the user experience of all users, no matter how they are accessing our system. But we know that even when we try to make things as intuitive as we possibly can, there are going to be places along the way that make people raise their eyebrows in confusion. One of them is the WYSIWYG editor.

Navigating Desire2Learn

At Desire2Learn, we really want to make it so that your focus is on taking your classes and learning the material you're in school for, not having to figure out how in the heck you're supposed to use the thing that's standing between you and those materials. So, we've tried to make navigating our stuff as consistent as we can. Here are some tips that should apply across the board to help make getting around our system a breeze.

Eliminating the Pains and Strains of Computer Use

Most would agree that computers are not inherently user-friendly. Many find using a computer to be painful, while others find daily computer use requires significant effort. These pains and strains of computer use are even more pronounced when the user is dealing with low vision or blindness. 

Most programs, however, can be controlled with keyboard shortcuts which often simplify the interaction.  Of course it would be overwhelming to try and learn them all. Instead, start with the most useful shortcuts in your most used programs and as well as some basic desktop shortcuts.

The USDA TARGET Center will be presenting a series of these shortcuts in this space.  More detailed trainings are also available online and in-person through the TARGET Center. 

Dolphin EasyReader 2.31

General Information on supported formats

Dolphin EasyReader is a software tool that not only reads DAISY 2.02 and DAISY 3 materials (including Bookshare material) it also reads HTML and text files. The EasyReader is available in more than 15 languages, including Spanish, Italian and German.

DAISY 2.02 and DAISY 3 materials contain multiple files.  Both formats contain a control file, NCC (DAISY 2.02) or NCX (DAISY 3), which keeps the material together. The text in the material is stored in an HTML (DAISY 2.02) or an XML (DAISY 3) file. The audio is typically streamed in MP3 format and the synchronisation between text and audio is controlled by SMIL files.

DAISY 2.02 materials can generally be protected by the PDTB scheme, however, the EasyReader can open materials that are protected with PDTB version 1.
