JAWS verses NVDA

Introduction


One of our new analysts Tehani, gives us her view on screen reader preferences, and why she prefers one over another.


Today screen reader users are spoilt for choice when it comes to choosing the right software to meet their needs. In the past, Jaws (Job Access with Speech) had the monopoly. There was supernova, but that didn’t fully meet my needs as a screen reader user. Jaws remained the preferred choice, and will always have a following due to it being one of the original screen readers blind people were trained to use. These days however, voice over and NVDA (None Visual Desktop Access) are starting to be a real alternative, and freedom scientific have to work hard to keep their customers happy.


Recently, NVDA has been receiving many positive plaudits for their work. I was a loyal Jaws user throughout my time in college and university until my husband and I had to consider getting a screen reader for our laptop at home. At college, Jaws was already on the computers, and at university, my disabled student allowance paid for a copy of the same software. We ended up deciding to try NVDA as there was no way that we could afford to spend £800 on Jaws, especially as we would need to spend more on upgrading in the future. In terms of mobile use, I had always used talx on Nokea, so when voice over became available on IOS I switched to that. No more paying for a device, then even more for a screen reader. Learning to use a touch screen took a lot of time but now I wouldn’t go back.


In my opinion, learning to use NVDA was the best thing we could have done, as I personally find it more responsive and intuitive than Jaws. For example, I find it much easier to access all elements from within one list rather than needing to remember several different short cuts. I can still use Jaws, and do so for my job, but honestly, I believe that in future web aim screen reader surveys, NVDA will certainly catch up, if not overtake freedom’s efforts. Saying this, due to its popularity, Jaws will always remain one of the screen readers of choice, especially for students going to university or college.


It is clear from my discussions with colleagues about screen reading technology that opinions are still mixed. When I set about writing this article I had a discussion with my colleagues to find out their views on the various screen reading software available. Starting the discussion, I thought that NVDA would be preferred overall, but I was surprised to discover that support for Jaws was still strong despite the cost and its complexities. I do believe though, that if Jaws is to continue to be a viable option to screen reader users, the cost will have to come down dramatically in order to compete with free options such as NVDA and voice over.

A brief explanation of the EU Accessibility Directive

Introduction

From September 2018, all public sector websites will need to conform to the new European accessibility directive. The directive has some exemptions, and provides additional time for some organisations to update their content and policies which I will detail below. So what is it, how does it affect you? Who is it aimed at? And what about Brexit? All these questions are answered in this post.


What is it?

The directive exists to ensure that all public sector organisations websites and apps are accessible, using existing accessibility standards. It aims to unify the standards throughout all EU member states, and requires that all members have a process in place for testing, and ensuring an on-going commitment to accessibility moving forward.


When does the EU directive take affect and what should I do?

All member states need to comply with the directive from September 2018. As the UK is still part of the EU by this date, it also means that UK public sector organisations should adopt the new directive. Using existing guidelines which form part of the Web Content Accessibility Guidelines (WCAG), members should ensure that as much content as possible is accessible to all users of desktop and mobile devices, including website and app content respectively. Point 19 of the EU directive indicates this to include textual and none textual information, including downloadable forms and documents, identification and payment processes. Taken from section 19 of the directive: ‘EU Accessibility Directive ST_9389_2016_REV_1_EN’.


What if I add content which is inaccessible?

If content becomes inaccessible, or poses a significant barrier to accessibility resulting from an update and is available for the general public to view, suitable alternatives should be provided to resolve any potential access issue as part of reasonable adjustments. All websites should have an accessibility statement detailing how their offerings can be accessed on desktop and mobile devices, and should list any limitations, such as items which are out of the control of the organisation.


Exemptions

A list of exemptions are included within the directive, to take in to account a variety of scenarios based on other factors which effect public sector organisations. An exemption in this instance means that at the moment, an organisation will not be required to comply, or an organisation will have more time to implement a solution based on their activity online. Point 22 of the directive does indicate that items which may currently be exempt, are subject to change if it is deemed possible to implement accessibility at a later date. In the same way as WCAG, all content should follow the same 4 principles which are:

    1. Perceivable, meaning that content should be displayed in a way that is easily navigated by all users on multiple devices.
      Operable, meaning that all content should be able to be displayed and interacted with by multiple users on a wide range of devices.
      Understandable, meaning that the content and user interface should be presented in a way which is easy to understand and use.
      Robust, meaning that all content and controls will work with a wide range of software including assistive technology.

  • What are the list of exemptions?

    There are several factors which mean that specific organisations may be exempt, however this depends on the operation of the organisation at the time of the legislation being adopted. The following are deemed as excempt as long as certain criteria are met. 1. Office documents, such as spreadsheets and PDFs, published before 23 September 2018; 2. Pre-recorded live video posted before 23 September 2020; 3. Live video (for example, a live press conference); 4. Online maps and mapping services, as long as there is an accessible version providing essential information for navigational purposes; 5. Third-party content which the public sector body has no control over; 6. Reproductions of items in heritage collections which are too fragile or expensive to digitise; 7. The contents of extranets and intranets published before 23 September 2019; 8. The content of web sites and apps which are considered archival, meaning they are not needed for active administrative purposes and are no longer updated or edited; 9. The web sites of schools, kindergartens, and nurseries, except for content pertaining to administrative functions. Taken from The Web Dev Law blog on the EU Accessibility Directive (external link).

    Using Siri from a blind person's point of view

    27/02/2018


    As a blind iOS user, I am often asked how I use Siri, the iOS voice assistant which became part of the iPhone 4S and a permanent feature of iOS since then. To avoid confusion, Siri is different from Voiceover, as Voiceover is a fully functional screen reader package, and Siri is a Voice assistant, and is similar to the google assistant on Android. While each person will use their own device slightly differently than another, what follows are some ways that I use Siri, and I hope it might give you some additional options to get the best out of Siri on iOS, or TV OS for Apple TV.


    What I do not do with Siri

    Firstly I thought it would be a good idea to include just a few examples where I don’t use Siri, mainly from a security point of view, and again these are just my personal views on Siri and may differ from other users of Apple products. I don’t use ‘hey Siri’, and I don’t allow access on the lock screen. While a very useful feature to many, the ‘hey Siri’ option can be activated by another user other than the device owner, which is also why I don’t use Siri on the lock screen. If Siri is allowed access to the lock screen, it is possible for anyone to do anything with your device while it is locked, including adjusting your screen brightness, calling people in your address book, and changing basic settings like your access preferences. Of course someone may use Siri on the lock screen to help find the owner of a lost device, but I am hoping I never need this option, because there is always ‘find my iPhone’, and I guess I am just slightly paranoid about security anyway.


    So how do I use Siri?

    I sometimes use Siri to send off a quick message which I don’t mind anyone else hearing, so it could be that I use the dictation feature with Siri to remind my wife about an addition to our shopping list. I also use Siri to set a timer when preparing food, or to find a phone number of an organisation which is not in my contact list. Of course there is the old favourite, when I will ask Siri to call a contact for me, and sometimes I ask it to turn on or off Voiceover if my screen reader crashes.


    I should add that I haven’t got round to using Siri on my Mac, as I am happy to use the existing commands available at this time with Voiceover. I do use Siri more on the Apple TV though, mainly to open menus, or search for programmes. As there is no ‘clock’ feature on Apple TV that I am aware of, I ask Siri for the time, and it will tell me. I do ask Siri for a quick weather update, and I get a very good description with a 5 day forecast. On Apple TV and iOS respectively, I also use Siri to play audio, and sometimes open apps. So I hope you have some additional tips for using Siri, enjoy and good luck.

    A review of the Apple TV with Voiceover

    22/01/2018


    Introduction

    As a totally blind user who is familiar with Voiceover on all Apple products, I have long thought about the accessibility of the Apple TV; and how it works with Voiceover. Recently my wife and I purchased the Apple TV, and it’s now our main device for viewing live and on-demand content. All a person needs is unlimited broadband.


    What is Apple TV?

    It is a little set-top box which connects to your wifi and a TV, allowing users to stream, download or mirror content from another device on the same network to the Apple TV. The latest version also comes with the Siri remote, which is a small rechargeable remote with 5 buttons in the centre, and a trackpad at the top. The trackpad can be physically pressed down to perform a selection, which is great for Voiceover users as standard gestures can be used to navigate content using the trackpad. All buttons are clearly spaced and are easy to identify with Voiceover running.


    Layout of the Siri remote

    Holding the remote with the charger connecter nearest to you, the layout of the buttons are as follows. From the bottom left Moving up to the top we have the play/pause button, the Siri button, and the menu button. On the right moving to the top we have the volume down/up, and the home button. Above the buttons is the trackpad, near the top of the remote. The home button also is used to access the app switcher, and to power off the device.


    Setting up Apple TV with Voiceover

    Once the set-top box is connected and powered on, press the menu button 3 times quickly to switch on Voiceover. You can then use standard gestures to select a language and time zone, and enter your apple ID information or create a new account. Typing on the Apple TV is time consuming, as users need to scroll to each letter and select it. For this reason it will be easier to download the ‘remote’ app to your iOS device, where you can type your information using the standard QWERTY keyboard. Don’t forget you can press the trackpad down, where you will feel a click to confirm a selection, rather than performing a double-tap which is the normal method of selecting items with Voiceover.


    Using the Apple TV

    The home screen of the apple TV will typically have the default films, TV programmes, settings, search and computers apps. You will also find the app store to install other apps to your apple TV. Some examples of apps might be: BBC iPlayer, Now TV and many others depending on what you require. You can navigate the home screen by making a single finger flick up, down, left or right; and then press down on the trackpad to open an app. Navigating apps is done in a similar way, and selecting a programme from a list will commence playback.


    Security and parental controls

    If like me you are concerned about young eyes and ears being exposed to content they shouldn’t be, Apple TV comes with parental controls which restrict access to Siri, apps, purchases and programmes by guidance rating. It is also possible to set a passcode for anyone who wants to mirror content to the Apple TV.


    Sharing with others

    The Apple TV by default allows you to add multiple accounts, this is so that other members of your family or organisation can access and use the TV. It is also possible to quickly turn on, or off Voiceover for sighted users to access their content. Simply just ask Siri to ‘turn off’ or ‘turn on Voiceover’. Another option is to set up the ‘triple click home’ accessibility shortcut, which is available on all iOS and Apple TV devices. This option allows users to press the menu button on the Siri remote, or the home button on iOS devices 3 times quickly to switch on or off a preferred accessibility option. In order to do this go to: Settings, General, Accessibility, and select ‘accessibility shortcut’. Enjoy your Apple TV.
