Many countries are introducing updated legislation that provides new compliance guidelines for accessibility. These new disability laws are fundamentally fuelled by the fact that many of the everyday conveniences we use had not been invented when accessibility laws were originally created. With that in mind, it is more vital than ever for companies to ensure their websites and software applications are accessible for people who are blind or partially sighted. In this blog, we will explore how organisations can use Dolphin ScreenReader and SuperNova to ensure their services are accessible and easy to use.
Dolphin ScreenReader is a screen reader for Windows computers. It is a core component of SuperNova Magnifier and Screen Reader, part of the SuperNova range. SuperNova and Dolphin ScreenReader are software that enables people with vision impairments to access, read and navigate the information on their computer. Hotkeys are keyboard shortcuts which are common to both products. In this article when a reference is made to 'SuperNova' it includes both SuperNova software and Dolphin ScreenReader.
This article will help organisations new to assistive technology to learn the basic controls of SuperNova for testing web content with speech.
Testing with SuperNova Magnifier and Screen Reader enables you to evaluate your site by providing you with the experience that screen reader users and magnification users would have.
When accessibility testing, it is important to ensure you are testing the accessibility of your website or application and not struggling to come to grips with the basics of using assistive technology.
To help, before planning any accessibility testing, we recommend that testers in your organisation learn the basics of how to use relevant assistive technology products.
If you are new to screen readers, we recommend you allocate some time (perhaps a few hours) to become comfortable using SuperNova. Don't get discouraged if things still seem confusing after only a few minutes. Slow down the reading speed and take your time. Remember that many screen reader users do not use a mouse, so try using only the keyboard as you become more comfortable with SuperNova.
Familiarizing yourself with assistive technology can take time. The good news is that you can download a free trial of SuperNova for Windows. This allows you to run SuperNova for 30 days, unrestricted and free of charge. After this period, you can purchase an unlock code to continue using it.
The SuperNova Range comes in three editions, with different licensing options to suit your business and your employees. Dolphin ScreenReader does not include magnification but still includes focus enhancements. It also visually tracks the cursor or application focus position, as a page is scrolled down, which is helpful for sighted colleagues.
If you are looking to test the accessibility of your website without a mouse, always choose Dolphin ScreenReader or SuperNova Magnifier & Screen Reader.
The SuperNova Enterprise and SuperNova Professional licences and trials both include all versions of SuperNova: Magnifier, Magnifier & Speech and Magnifier and Screen Reader. Please note that the magnifier only version does not include the virtual cursor required for web browsing with a keyboard only.
Once you are familiar with your Dolphin assistive technology products, a good place to begin accessibility testing is to ensure whether text from your web page or application can be read easily by a blind or partially sighted customer.
Many keyboard shortcuts allow you to read web content. The following is a list of essential reading shortcuts that are available within SuperNova. With these shortcuts, you should be able to read through most content.
You may want to practice reading through this page with SuperNova right now to try these commands out.
Sighted users usually visually skim a webpage for headings, lists, tables, etc. You can navigate by these types of content in SuperNova, if the site is correctly structured and well organised.
To navigate forward and backward through links and form elements on the page, use Tab and Shift + Tab. Other shortcuts are listed below.
The following Quick Keys will help you navigate common page elements.
To practice reading and navigation commands, try refreshing this page and navigating to this section of the page. There are several ways you can do this - navigate to the Table of Contents and activate a link to this section and then begin reading or navigating by sentence, headings (H), lists (L), Find, Read Previous/Next line (↑/↓).
SuperNova's speech reads back any image's alternative text - alt text are descriptions that have been "tagged" or added to the image to provide a description for users with sight loss. If alternative text is not defined, a screen reader will typically ignore it, except in some cases where the image has a function.
To navigate to the next table in a page, press the T key. To navigate within a data table, hold down DOLPHIN and use ↑/↓/←/→ to move from cell to cell. If a table has proper row and column headers, pressing SHIFT + NUM PAD 0 will announce current cell information including headers. If headers are not correctly defined, this key will announce the cell position (i.e. “column 3, row 2”)
When a form control gets keyboard focus, first its label is announced by SuperNova, then it will announce the type of form control, like a drop down box or radio button. If a group of form controls - typically groups of checkboxes or radio buttons - are contained in a field set with a legend, SuperNova presents items in a field set as a group. It reads the legend when you first navigate to anything within the group.
Use the following browser keyboard controls to interact with form controls:

Since screen readers use many of the keys on the keyboard for quick navigation, filling in a form or interacting with a widget presents a dilemma. For example, when pressing the "H" key, how does a screen reader know if you want to navigate to the next heading or enter the letter into a textbox?
SuperNova takes care of this by switching between two modes:
'Dolphin Cursor' is the default mode for reading and navigating the page - this is the mode where the H key takes you to the next heading. Whereas ''Forms Mode' passes almost all keystrokes on to the browser - this is the mode where the H key puts the letter H in a text box.
SuperNova will toggle between these modes automatically - assuming you are using the Tab key to navigate - based on the type of thing that has keyboard focus. SuperNova announces the change to Forms Mode with a spoken prompt. This occurs when you navigate to text boxes or other inputs or widgets that require keyboard interactions. When you exit the form, it will announce the change back to Dolphin Cursor.
Tip: Press DOLPHIN + ENTER to toggle between Forms Mode and Dolphin Cursor manually. Though this should not be necessary for widgets that are properly coded.
Leveraging the features of SuperNova assistive technology enables you to simulate the experiences your customers and prospects with visual impairments have when they navigate your website. This can provide you with a unique insight - one your competitors might not have - into how your brand is perceived by a larger group of potential customers.
If you use SuperNova and Dolphin ScreenReader when you write and design websites and other brand material, you are taking an 'accessibility first' approach. This is easier and more cost-effective than retrofitting accessibility to your site!
You can also use SuperNova and Dolphin ScreenReader to check the accessibility of other content. This might include electronic or written material such as company emails, newsletters, brochures etc.
