What is accessibility


Accessibility means that website, tools and Technologies are designed and developed so that people with disabilities can use them. We usually relate accessibility with persons with disabilities, but keeping websites open and accessible to all also helps other populations, such as those who use mobile devices or have slow response Internet connections.

What is accessibility

Accessibility may also be defined as considering everyone the same and providing equal chances regardless of background or situation. Removing anyone from a website or from any platform because he/she belong to disable category is wrong, just as it is wrong to exclude someone from a physical building because they are of a disability. We're all different, but we're all the same.

Making content, activities, and surroundings as understandable, useful, and usable as feasible so that as many people as possible is known as accessibility. Accessibility should be in every sector, such as education, medical, agriculture, IT sector etc.

It is the right thing to do to be accessible. For example, in some nations, offering accessible websites is required by law, which might open up new markets for businesses that would otherwise be unable to utilize your services or purchase your products.

Over the last two decades, the accessibility of software applications has improved. This article examines the platforms that have been developed and provides advice for developers to design accessible programs.

Accessibility of software tools

The program Access Convenience for Windows 2.0 improved the accessibility of Windows for people who are deaf, hard of hearing, or have limited dexterity by allowing changes in the use of the keyboard and mouse, providing visual alerts for the computer's sounds, and enabling the computer to be operated via serial port devices.

The needs of the people with impairments were not considered when designing these operating systems. Many people, especially those who are visually or partially challenged, were unable to use Microsoft Windows operating system programs. These programs expected that computer users would be able to:

  • Read and respond to text and images on the screen.
  • Type on a conventional keyboard.
  • Use a mouse to pick text, photos, and other material.
  • Reacted to the sounds that were played.

If a person has been unable to perform one of the activities described above, they will be unable to use several popular computer programs.

Alternative ways to make accessible screen contents

For visually impaired people, most computer applications are difficult or even impossible to operate because they are so visible. This does not have to be the situation.

1. Text-to-speech (TTS): Text-to-speech (TTS) is a type of talking program used by people who cannot read print. TTS can also replace the voice of persons with other print difficulties, such as illiteracy or those unable to speak. Finally, general people might benefit from this technology, which could be used on portable and mobile appliances or receive data when the eyes are occupied elsewhere.

2. Magnification: It expands the contents of the display. A larger typeface, a built-in better contrast background, or an extra-large display for persons with low eyesight may be sufficient. Screen magnification programs can be utilized instead.

3. Braille: A solution utilized by deaf-blind people for silent reading and meticulous study and deaf-blind people. This can be in the format of braille embossers or physical copy braille.

Alternative Ways to Enter Data

Another issue is how disabled persons enter data onto computers. You might not be able to text on a standard keyboard or use a mouse if you are physically challenged. Here are a few other options for physically challenged people to get relevant data:

  1. Sticky buttons: Make it simple to enter modifier keys. To make an uppercase, hit the shift key, then remove it before pressing the letter to be capitalized. People who only have one functional hand or have no need for their hand's type with a pen in their mouth employ the sticky key method.
  2. Speech recognition: Enables users to converse with computers. This technology has progressed significantly, but it still needs further integration into mainstream applications.

Accessibility of software tools

Lack of Context

Many accessibility hardware and software providers produce equipment and software to assist persons who cannot execute one of the four essential tasks outlined above. Screen going to read software, TTS, alternate hardware, translator software, screen optical zoom software, and reading skills software are all types of advanced devices and software that allow a bad spelling or learning disabled computer user to see and listen to the message as it is modified on the computer screen.

The value of accessibility suppliers' efforts cannot be overstated, as their solutions have considerably enhanced the job and personal fulfillment options of thousands of individuals with impairments.

However, many options fall short of giving people with disabilities a fully accessible and usable workplace. Due to a basic context issue, a user's engagement with a computer is influenced by the condition in which it occurs.

For example, one program may use the visual of a bulb to show that it is performing a task, while others might use it to signal that the work has been completed. The blind person will be unable to interpret what the program is seeking to express unless the application somehow informs them of the meaning of these fluorescent bulb pictures. Similarly, to understand what a customer is saying, speech recognition software frequently needs information about the context to encounter.

Importance of accessibility

In modern times, classrooms are affected by the shift from paper to digital materials. Instructional technology can be enjoyable, interactive, and directly linked to syllabi and evaluations. The effect of accessibility on online education will be explored in this session.

  1. Impact of accessibility in education
    In education, accessibility relates to how technology is utilized in class and accessed. Students can utilize software, programs, and other things to access online media areexamples of this. The time of students buying textbooks and teachers wasting months preparing work packs for pupils is essentially gone; today's students are required to accomplish work using digital resources. This assumption is exacerbated by the reality that not all students have equal access to online materials. Even if they have, they could have difficulty reading and interpreting the content.

    Teacher education is no longer thought to be something that only a few educators do or that only occurs just outside of the school. Instructional technology is increasingly implemented into classes and teaching resources, such as textbooks, practice, quizzes, and assignments. Schools can involve adding a few computers or tablets in each classroom to a 1:1 school, where the education department supplies each student with a tablet or computer.
  2. Impact of accessibility in the workplace
    Employers that ignore accessibility risk having a staff that struggles to achieve its objectives, which may lead to frustrations and even resignations, resulting in a loss of talent and low morale.

    Becoming an accessible employer involve removing barriers in your workplace, hiring methods, and work environment and being open and tolerant of all workers and applicants with disabilities. Through distinct, creative ideas, diversity creates creativity.
  3. Cognitive impairments and illiteracy
    A person with memory loss can benefit greatly from images, symbols, and graphic imagery. Individuals with Dyslexia, for example, may consider it difficult and time-consuming to obtain textual material. This can be easily remedied by using appropriate photos.

    This example demonstrates how small modifications may make a big difference for people who struggle with reading.

    Recommendations and auto-complete features can be really helpful. Tips may help people navigate more easily, especially if they have trouble remembering things or if making decisions makes them anxious.
  4. Visual impairments
    The most popular approach for blind people to access the Internet is through a browser and a display translator (also known as text-to-speech software). Microsoft Translator for Windows and Narration for Mac are two of the most widely used screen readers.Anyone designing for visually challenged consumers must recognize how text-to-speech software helps them "read" webpages. Here's how it works: A screen reader is a software program that converts Web content into clear text. It then examines the full page and speaks it loudly, line by line, one piece at a time, linearly.

Summary

Accessibility is a sphere where every person, whether disabled or abled, makes sure that he or she will complete his task in every situation and have an alternative for each problem.
