System Requirements

UEB Online Accessible is designed to be used with a combination of standard web technology (browser and keyboard) along with assistive technology such as screen readers and refreshable braille displays for enhancing the experience for visually impaired learners.

While UEB Online Accessible can be used with different types and versions of various technology, there is a standard operating environment that we recommend for optimum completion of the course. We have found that the following combination of technology is best suited.

Note: As a minimum you will need a computer connected to the Internet with a Browser and a Screen Reader. The use of a Refreshable Braille Display is optional.


UEB Online is designed to work with a PC or Mac computer that must be connected to the Internet to access the program. We recommend the use of a computer with a supported Windows operating system (Windows 7 or later) as that will run the remainder of the recommended configuration.

Note: UEB Online cannot be used with a touch device running either the iOS (e.g. iPad) or Android (e.g. Samsung Galaxy) operating systems.


We recommend the use of a recent version of Firefox by Mozilla which is available as a free download. Alternatively you can use a version of Internet Explorer provided in your Windows operating system that is at least version 10 or above. At this stage Microsoft Edge browser is unsupported.

Screen Reader

We recommend using NVDA, a screen reader available as a free download from NV Access which runs on Windows operating systems. A minimum of V2015.3 NVDA is recommended.

Suggested Configurations

If you use JAWS screen reader, we suggest you use Internet Explorer as the browser for best operation.

If you use NVDA screen reader, we suggest you use Mozilla Firefox as the browser for best operation.

Refreshable Braille Display

A refreshable Braille display is a piece of technology which is used in conjunction with the screen reader to produce a Braille output of the words being read by the screen reader. The pins on the braille display are moved up and down as needed to produce the 6 or 8 dot pattern corresponding to the letters or words being output by the screen reader.

The Braille display is a useful tool for a learner to be able to ‘feel’ the dots as they are read out verbally.

Every effort has been taken in UEB Online development to ensure that a refreshable Braille display can be used as part of the learning process. However there are a number of intrinsic interoperability issues which means the use is less than optimal.

An example of this is that as each word is being read out during the exercise data entry, the braille display is changed to reflect that. This means all previous content on the display is lost. As a result UEB Online is unable to produce a group of words simultaneously on the Braille display. Instead UEB Online focuses on ensuring that the current word being typed is reflected on the Braille display so that each word can be felt, rather than a sentence or group of words.

For this reason we suggest the use of a refreshable Braille display as an optional tool for learning only and is not a requirement to complete UEB Online.

During development and testing we used the Focus 40 Blue from Freedom Scientific.

Note: If you are unable to access the combination recommended above then please contact us and we will attempt to guide you in your system setup.
