"Disability describes the social exclusion and barriers imposed on people with disabilities and impairments evoke an unpleasant feeling in us, and it is the feeling which motivates how we react when we face disability and people with disabilities." – Brian Watermeyer 

South Africa commemorates National Disability Rights Month, known as DRAM, annually between 3 November and 3 December. International Day of Persons with Disabilities, also known as National Disability Rights Awareness Day, is celebrated on 3 December. The theme for 2021 is ‘The Year of Charlotte Manye Maxeke – Create and Realise an Inclusive Society Upholding Rights of Persons with Disabilities’. 

Disability is a quintessential post-modern concept, because it is complex, variable, contingent, and situated. One is always disabled concerning the context in which you are put, subject to many definitions from different perspectives, and is used for various disciplines ranging from medicine, sociology, and political science. To fully comprehend disability, one needs to consider multiple perception models in the quest for a better understanding of disability; so-called ‘models of disability’ emerge in disability research. In line with most notions of disability, it could be associated with the medical model, social model, human rights model, and biopsychosocial model. Disability models aim to demonstrate how society perceives, understands, and addresses the needs of people with disabilities. 

The Disability Models 

Medical model: views disability as a personal tragedy in need of cure and rehabilitation.  

Social model: views disability as predominantly a socially driven issue; allows us to reconstruct social inequality for people with disabilities as a collective experience of discrimination and injustice, rather than a personal tragedy affecting only individuals. However, the model does not address the emotional aspects of disability and the realities of impairment.

Biopsychosocial model: views disability as a combination of an individual's state of health and their surrounding environment, that is, society. By recognising disability as a social construct of intricate variables and interaction of biological factors (genetic, biochemical, etc.) and psychological factors (mood, personality, behaviour, etc.), the social aspects (cultural, familial, socio-economic, and medical, etc.) is to recognise the complexity; specifically, the intersectionality that informs disability is recognised.

The human rights model: assumes that societal barriers can only be removed by guaranteeing rights to people with disabilities. Human rights principles recognise that fundamental rights are inherent in all human beings, regardless of race, gender, ability, and nationality. Therefore, disability rights are viewed as a human right under this paradigm, advocating for equal participation and opportunities for individuals with impairments. 

Promoting the human rights of people with disabilities, the White Paper on the Rights of Persons with Disabilities in South Africa mandates a universal design approach, which is defined as "the design of products, environments, programs, and services to be usable by all persons to the greatest extent possible without the need for adaptation or specialized design."

As per the Global Education Monitoring report on inclusion and education, the Universal Design for Learning (UDL) framework is particularly relevant for a comprehensive understanding of inclusive education as tackling barriers to learning, noting that "the Universal Design for Learning concept encompasses approaches to enhance accessibility and eliminate barriers to learning." Such an approach can help to integrate UDL into the educational system by addressing the various social, emotional, and learning requirements of different groups while working for the universal system-related goal.

South Africa is among the few countries in the world to have signed and ratified the most acclaimed global convention on disability in 2007. The international trend endorsed by the United Nations Convention on the Rights of Persons with Disabilities (UNCRPD) seeks to promote, protect, and ensure the full and equal enjoyment of all human rights by persons with disabilities. Although disability is varyingly defined, and definitions change across time and space, the UNCRPD defines persons with disabilities to include long-term physical, mental, intellectual, or sensory impairments, which in interaction with various barriers may hinder their full and effective participation in society on an equal basis. For this reason, creating and realising an inclusive upholding of the rights of persons with disabilities is critical in building an enabling environment for all. However, despite progressive legislative structures in South Africa, persons with disabilities continue to face barriers that prevent equal access to opportunities and participating fully in all aspects of life. It is primarily due to inaccessible infrastructure, prejudice, stigmatisation, discrimination, and attitudinal behaviour towards persons with disabilities, which often result from a lack of understanding.  

According to Stats SA, 80% of persons with disabilities aged 20-24 are not attending tertiary education, yet the population of students with disabilities at tertiary institutions is just 1%. It is also revealed that there is a strong demographic gap between races. Access to education is necessary for advancing sustainable development, but it is evident that inclusivity within tertiary education remains out of reach for many.  The University of the Free State aims to foster disability inclusion within the Integrated Transformation Plan, which is in line with the universal access approach guided by the Centre for Universal Access and Disability Support (CUADS). 

CUADS, a well-known disability unit, was established in line with non-discrimination legislative changes and inclusive policy frameworks for access and equal participation for students with disabilities. It serves as a bridge between students with disabilities and the institution, ensuring mutual understanding. The majority of such departments are led and managed by women, as women have a dynamic role in enhancing and nurturing the aspirations of children and youth with disabilities to get access to education. Despite the positive role of these departments in the full inclusion of students with disabilities, attitudinal barriers remain a challenge to their non-disabled counterparts. 

Furthermore, female students with disabilities face particularly higher levels of marginalisation and disadvantage because of the double discrimination based on their disability and gender. Their status as women renders them vulnerable to gender-based violence (GBV), including sexual abuse, maltreatment, exploitation, and intimate partner violence (IPV) compared to men with disabilities. 

South Africa has a high prevalence of GBV, especially IPV. Women with disabilities are more at risk and experience an additional layer of violence compared to women without disabilities and men with and without disabilities. It is also revealed that blind women and women with severe intellectual and mental disabilities are equally perceived as highly exposed to GBV compared to women with other disabilities (e.g., if an intellectually challenged individual could not give informed consent and/or when they report it, it will be difficult for them to identify the perpetrator). 

Furthermore, men with disabilities are at greater risk of GBV, but not comparable to women and girls with disabilities. The gap perpetuates unequal gender relations in all contexts of South Africans’ lives. While various organisations seek to promote women's rights in GBV advocacy, there is relatively little emphasis on GBV against persons with disabilities, including violence against women and children. 

To build an inclusive society, one needs to understand intersectionality concepts that provide a prism to comprehend marginalisation and exclusion better. Understanding intersectionality is related to how various identities such as race, gender, class, disability, sexuality, and others intersect – how lived identities are seen as entwined with oppressive systems that are mutually constitutive and reinforcing. Intersectionality as an approach recognises how complex reality is and how this complexity informs social conditions and behaviour; it acknowledges that people's lives are defined by multiple layered identities that derive from social relations, histories, cultures, and other operations of power structures. 
It is an analytical tool for exploring, comprehending, and responding to how gender intersects with different identities and how these intersections lead to distinctive oppression and privilege experiences. Also, intersectionality addresses how social structural norms such as racism, patriarchy, classism, and other social systems of discrimination function and interact to create social inequalities that shape attitudes and behaviour towards those who are different, such as those with disabilities. The approach invites us to shift away from binary thinking and towards a more global human rights stance.

Therefore, higher education institutions have a critical role in shaping the future of society as places where students are educated and prepared for their future vocations. In line with inclusive curricula, the university should introduce disability discourse into models such as UFSS, which is mandatory for all first-years. Also, the institution should increase awareness and visibility by incorporating critical disability messages into all discussions, addressing all aspects; utilising disability posters on campus, and departments such as Residence Life, KovsieSport, UFS Centre for Teaching and Learning (CTL), and CUADS should collaborate to host disability events and heighten communication around it; leveraging other mega events such as national days, themed days, conferences, etc., to spread messages on disability and to build an inclusive society; hosting lectures, debates, and discussions on disability topics and promoting rights of persons with disabilities; and hosting student competitions on equality, justice, and human dignity. Through such interventions, the university will have a community that can facilitate the creation of inclusive spaces in their homes, communities, work, and social areas. Disability should be a collective responsibility to achieve an inclusive society that upholds the rights of persons with disabilities. 

Inclusive legislative policies (i.e., the White Paper on the Rights of Persons with Disabilities, 2018 and the Strategic Policy Framework on Disability for the Post-School Education and Training sector) should guide institutions to ensure that students with disabilities are protected. These documents further promote the right to (inclusive) education, as a universal access approach in education does not benefit only students with disabilities, but everyone.

Eye tracker device a first in Africa
2013-07-31

Keeping an eye on empowerment

"If we can see what you see, we can think what you think."

Eye-tracking used to be one of those fabulous science-fiction inventions, along with Superman-like bionic ability. Could you really use the movement of your eyes to read people's minds? Or drive your car? Or transfix your enemy with a laser-beam?

Well, actually, yes, you can (apart, perhaps, from the laser beam… ). An eye tracker is not something from science fiction; it actually exists, and is widely used around the world for a number of purposes.

Simply put, an eye tracker is a device for measuring eye positions and eye movement. Its most obvious use is in marketing, to find out what people are looking at (when they see an advertisement, for instance, or when they are wandering along a supermarket aisle). The eye tracker measures where people look first, what attracts their attention, and what they look at the longest. It is used extensively in developed countries to predict consumer behaviour, based on what – literally – catches the eye.

On a more serious level, psychologists, therapists and educators can also use this device for a number of applications, such as analysis and education. And – most excitingly – eye tracking can be used by disabled people to use a computer and thereby operate a number of devices and machines. Impaired or disabled people can use eye tracking to get a whole new lease on life.

In South Africa and other developing countries, however, eye tracking is not widely used. Even though off-the-shelf webcams and open-source software can be obtained extremely cheaply, they are complex to use and the quality cannot be guaranteed. Specialist high-quality eye-tracking devices have to be imported, and they are extremely expensive – or rather – they used to be. Not anymore.

The Department of Computer Science and Informatics (CSI) at the University of the Free State has succeeded in developing a high-quality eye tracker at a fraction of the cost of the imported devices. Along with the hardware, the department has also developed specialised software for a number of applications. These would be useful for graphic designers, marketers, analysts, cognitive psychologists, language specialists, ophthalmologists, radiographers, occupational and speech therapists, and people with disabilities. In the not-too-distant future, even fleet owners and drivers would be able to use this technology.

"The research team at CSI has many years of eye-tracking experience," says team leader Prof Pieter Blignaut, "both with the technical aspect as well as the practical aspect. We also provide a multi-dimensional service to clients that includes the equipment, training and support. We even provide feedback to users.

"We have a basic desktop model available that can be used for research, and can be adapted so that people can interact with a computer. It will be possible in future to design a device that would be able to operate a wheelchair. We are working on a model incorporated into a pair of glasses which will provide gaze analysis for people in their natural surroundings, for instance when driving a vehicle.

"Up till now, the imported models have been too expensive," he continues. "But with our system, the technology is now within reach for anyone who needs it. This could lead to economic expansion and job creation."

The University of the Free State is the first manufacturer of eye-tracking devices in Africa, and Blignaut hopes that the project will contribute to nation-building and empowerment.

"The biggest advantage is that we now have a local manufacturer providing a quality product with local training and support."

In an eye-tracking device, a tiny infra-red light shines on the eye and causes a reflection which is picked up by a high-resolution camera. Every eye movement causes a change in the reflection, which is then mapped. Infra-red light is not harmful to the eye and is not even noticed. Eye movement is then completely natural.

Based on eye movements, a researcher can study cognitive patterns, driver behaviour, attention spans, even thinking patterns. A disabled person could use their eye-movements to interact with a computer, with future technology (still in development) that would enable that computer to control a wheelchair or operate machinery.

The UFS recently initiated the foundation of an eye-tracking interest group for South Africa (ETSA) and sponsor a biennial-eye tracking conference. Their website can be found at www.eyetrackingsa.co.za.

“Eye tracking is an amazing tool for empowerment and development in Africa, “ says Blignaut, “but it is not used as much as it should be, because it is seen as too expensive. We are trying to bring this technology within the reach of anyone and everyone who needs it.”
