Challenges and Barriers to Successful Employment for Man with Visual Impairment

I was born with normal eyesight, and at the age of three and a half it was determined that I had a visual impairment. By the time that I was about seven years old, I had lost most of my eyesight.

At the inquisitive age of four, I wanted to know how things work and how a box could have different voices coming out of it. Learning about radios was the beginning of a path to a career in the technology industry.

At the age of 15 I built my first computer at a time when components were starting to decrease in size.

Jerry-Rigged IT Systems

In the early 80s, I went to work for a Fortune 500 aerospace company. I was hired as an “experimental employee” because they had never hired a blind person before.

Back then there was hardly any assistive technology to speak of. Several companies were starting to develop a screen reader for MS-DOS, but in many cases these screen readers only worked with some specific programs.

Some of us with visual impairments, in order to maintain our jobs, had to be creative and figure out a way to generate speech output.

For me, I used an old Votrax speech synthesizer like a printer driver. Every time I wanted to know what was on the screen, I executed a print command that would convert the data on the screen to a format that Votrax could read and then speak aloud in probably the worst speech synthesizer voice that one would want to hear. Nevertheless, I was able to get the job done.

As technology continued to evolve in terms of processing speed and better video graphics, it paved the way for the beginning of a graphical user interface, which today is commonly known as Windows. This progress made it difficult for the blind user to keep up with the new changes because the screen reader at that time could not accommodate off-the-shelf hardware and software improvements. Partially-sighted people had to modify video settings to accommodate their visual requirements.

Mobile Devices

As technology continued to move towards a touch screen environment with no real interaction solution for the blind consumer, it seemed as though the blind and individuals with various degrees of visual impairment would not be able to move away from conventional mechanical user interface technology like the flip phones with the tactile keypad.

Once multilayered technology was introduced to hardware and software developers, companies like Apple and Google started to develop a user interface that consisted of gestures and tapping concepts that allowed for the interaction and execution of commands and operations.

As part of their Universal Access initiative in 2007, Apple introduced VoiceOver, a screen reader output interface for the iPhone 3GS. Apple demonstrated that touch technology could be made accessible for everyone, and in today’s work environment mobile technology is something that we all depend on.

We still have to deal with third-party applications that have the potential to be used by the visually impaired community, but we can’t use these apps because the developers either are not familiar with accessibility coding guidelines or choose to make apps more visually appealing in the hope that screen readers will provide a level of accessibility for the blind or visually impaired user.

One of the first barriers that we had to deal with had to do with educating the developers on what text-to-speech technology is and how it differs from speech recognition. This has been a problem for a long time and will continue to be a problem that affects us because developers believe speech recognition programs meet our needs. The reality is that these programs make it possible to receive speech input, but they do not read what appears on the screen.

In the case of smartphones, many app developers feel that built-in artificial intelligence (AI) programs are the same as the devices’ built-in screen readers (Apple’s Siri vs. VoiceOver, Android’s Google Assistant vs. TalkBack, Windows’ Cortana vs. Narrator) and that the built-in AI programs are all the visually-impaired user requires. Unfortunately, these AI programs are voice-driven search services that will in most instances provide audio feedback, but they are not screen readers that function without internet connectivity.

The issues described above are quite common in the desktop environment as well. The best way to resolve this issue is by requiring developers to submit their applications to a level of accessibility compliance verification before an application is deployed.

Technology in the Workplace

While technology has come a very long way and has made it possible for the blind and visually impaired to be competitive employees, there are many road blocks to still overcome for equality in the workplace.

Even with all the new advances in technology and software development today, blind or visually impaired professionals are still encountering barriers with their ability to carry out their job duties.

For example, the idea of providing PDF file attachments so that anyone, regardless of the platform being used, should be able to open the file can sometimes be an issue for some of us that use screen readers or screen magnification tools.

Often because of company policy, we are issued a computer equipped with a common commercially-available PDF reader, which does not do well making PDF images accessible. Some companies, like my employer, have smart printers/copiers that can scan a document and generate a PDF image that is not easily converted to text that can be read by the screen reader. Sometimes it is easier to print the image file and then use an optical character recognition tool to scan and read it. This is time consuming and a waste of paper.

Another on-the-job issue that we face is a lack of quality interaction and support with Information Technology (IT). While the IT staff is able to maintain and support staff using the general issued computers and software, they often don’t have the knowledge or experience to install, configure and maintain the adaptive technology.

If the IT specialist installs the specialized adaptive software, many times they do not install it correctly causing the program to fail to operate properly or at all due to the lack of the resource requirements needed for the software to run efficiently.

This is like keeping a car engine pristine with four flat tires.

In many cases, permission to update the software as needed is denied due to company policies, which leaves the assistive technology unable to keep up with the many updates and changes that the operating system and other programs the IT department regularly update to keep the hardware and software running at peak performance.

Support in the Workplace

My previous job as well as other companies will hire an assistive technology specialist to install the needed software and provide specialized scripting for the software to run on the company created software.

The software runs great until the first major update the IT specialist pushes to all computers on the network. This can affect scripting performance that was created so that the disabled user could fulfill his/her job. Often the assistive technology user has to make due with inadequate software accommodations until the company will bring in the assistive technology specialist again at a substantial fee to reinstall the scripts or create new ones if needed.

These costs and roadblocks could be minimized if employers include the employee who will be using the assistive technology so that he or she can provide input during the discussion and planning phase up to the point that it gets delivered and installed.

Developing and implementing all-inclusive collaborative meetings to address assistive technology needs will yield a more positive interactive communication and success among all participants.
