As per UNCRPD, 2006 (United Nation Convention on Rights of Persons with Disabilities), accessing web content and contributing to web content is a basic human right which should not be limited in any form.

Every company or organization publishing web content has a shared responsibility to follow international standards and best practices for web accessibility. These standards and best practices are not always followed due to various reasons – such as lack of awareness, cost and availability of the needed expertise. This in turn, has an adverse impact by creating an inaccessible and non-inclusive digital eco-system.

Our vision is to facilitate the creation of an inclusive digital ecosystem for persons with disabilities.

Our mission is to offer affordable , high-quality digital accessibility testing services for companies and organizations which aspire to create highly accessible digital systems and to offer high quality training programs in digital accessibility to persons with disabilities to help them become competent testers.

Accessibility refers to the ability of people with disabilities to have access to and benefit from an entity or system. Digital Accessibility refers to the ability of users with disabilities to effectively utilize information technology (IT) systems including web sites, mobile or web based applications, software and hardware. Digital Accessibility is generally concerned with ensuring that IT systems are designed in such a way that they interact appropriately with assistive technologies. Extensive accessibility legislation is present in most of the major domestic markets including the United States, Canada, the European Union, Australia and Japan. Generally, the relevant portions of accessibility legislation require that organizations make best efforts in order to ensure that physical and electronic business areas can be used by individuals with disabilities.

Disability Demographics

Demographic trends throughout first world countries indicate that the citizens with disabilities, as part of the overall population, will grow over the next fifty years. This is generally interpreted as a sign that current disability legislation will be expanded or more aggressively enforced in the future.

Disability Types

A disability is any condition of the body or mind (impairment) that makes it more difficult for the person with the condition to do certain activities (activity limitation) and interact with the world around them (participation restrictions).

Assistive Technologies

Most people with severe disabilities use assistive technology in conjunction with core operating system functions to access information in digital systems. Assistive technology commonly refers to products, devices or equipment, whether acquired commercially, modified or customized, that are used to maintain, increase or improve the functional capabilities of individuals with disabilities.


Web Accessibility Perspectives

There are many examples in society of innovations that were originally intended for people with disabilities but that have provided access benefits to all people (curb cuts and automatic door openers are two of the most common). Accessible web content is a similar innovation.


WCAG 2.0

The Web Content Accessibility Guidelines, often abbreviated to WCAG, are a series of guidelines for improving web accessibility. Produced by the World Wide Web Consortium (W3C), the WCAG are the best means of making your website useful to all of your users. Checkout more on WCAG principles, guidelines and conformance levels.

Mobile Accessibility Guidelines

Mobile technologies are developing in leaps and bounds changing the world around. So it’s no surprise they are now used in educational and rehabilitating programs for people with special needs based on accessibility. The whole thing seems pretty basic now, yet we have no doubts its future is bright.

Universal Design

Universal Design is the design and composition of an environment so that it can be accessed, understood and used to the greatest extent possible by all people regardless of their age, size, ability or disability. An environment should be designed to meet the needs of all people who wish to use it.

Universal Design for Learning

Universal Design for Learning is an educational framework based on research in the learning sciences, including cognitive neuroscience, that guides the development of flexible learning environments that can accommodate individual learning differences. Checkout the CAST curriculum on UDL.


ARIA Authoring practices

WAI-ARIA, the Accessible Rich Internet Applications Suite, defines a way to make Web content and Web applications more accessible to people with disabilities. It especially helps with dynamic content and advanced user interface controls developed with Ajax, HTML, JavaScript, and related technologies.

Accessibility Laws

According to the W3C, web accessibility is a practice of removing barriers so people with disabilities can “perceive, understand and interact with the web”. When websites are designed & developed with accessibility in mind, all visitors have equal access to, and can engage with, a site.
