Prof Lizette de Wet, pioneer in the field of Human Computer Interaction

“I consider obtaining my PhD while balancing my work, my marriage, and two young daughters (who did not sleep through before reaching age four!) as one of my biggest achievements,” says Prof Lizette de Wet, Associate Professor in the Department of Computer Science and Informatics at the University of the Free State (UFS).

Many firsts

Her achievements in the field include much more than the PhD referred to. On 11 February, International Day of Women and Girls in Science, the UFS celebrates her for pioneering the human-computer interaction (HCI) research environment, specifically the evaluation of usability and user experience in diverse application areas, where she has experienced and established many firsts.

Prof De Wet was one of the first students to complete a master’s degree in this discipline at UNISA (1994). She says the external examiner for her master’s was from the University of York in the UK, as expertise in South Africa was still lacking at the time.

In the Department of Computer Science and Informatics at the UFS, she established the HCI research area. This involved undertaking research projects in the discipline and developing curricula for a second-year module, an honours module, and a master’s module.

“The second-year module was also one of two modules on campus to first use iPads in class to assist in a blended learning approach,” she says.

A woman’s contribution

Prof De Wet believes that in the research field of HCI, the focus is on the user and his/her overall user experience (including emotions, feelings, and competence) when using computers. “Taking the human being into consideration is much more important than simply concentrating on the programming code that needs to be written.”

Whether the human being writing the code is male or female, does not matter. Prof De Wet is of the opinion that there is no gender distinction between what women and men could achieve in the field of Computer Science and Informatics.

“Although the students are still predominantly male, in the past few years more and more female students have enrolled for our postgraduate studies and completed it successfully, some of them with exceptional marks. In South-Africa, many women are making their mark in this discipline by being heads of departments at universities or in the private sector, by chairing national and international conferences, and by publishing ground-breaking research,” she adds.

Success with virtual reality

Over the past few years, Prof De Wet has concentrated on using brain-computer interfaces (BCIs) and virtual reality in her research. By the end of 2020, she had successfully supervised 11 master’s students and four PhD students, with one of the master’s students delivering ground-breaking research using virtual reality in the training of nursing students.

She elaborates: “The prototype involved virtually examining and evaluating a patient (with a foreign object lodged in a lung) in a virtual ward while wearing an Oculus Rift headset. The evaluation results were extremely positive and will be continued as a PhD study to investigate how to attempt to relieve motion sickness in an immersive virtual clinical simulation.”

Starting out as someone who never had the opportunity to lay her eyes on a computer during her school years, Prof De Wet is of the opinion that in South Africa – being a Third World country – there are numerous opportunities to make computers accessible to rural communities, and even to the large senior population who did not grow up with technology and might fear it.

With her passion for the profession, she not only delivers pioneering work, but also trains professionals in computer sciences who will contribute to a better tomorrow.

UFS plans to improve undergraduate pass rate

2005-01-13

The University of the Free State (UFS) will introduce a new foundation programme this year 2005 in an effort to improve the academic performance of undergraduate students.

According to Mr Francois Marais, Head: Centre for Higher Education Studies and Development (CHESD) at the UFS, the programme will assist students by providing for the development of cognitive and critical thinking skills by means of the integration of appropriate thinking skills (such as creative thinking, decision-making, problem solving, reasoning, and how to learn), into the subject content of university courses.

“The foundation programme will benefit students from disadvantaged school backgrounds and, in future, those whose performance in proficiency tests points to the need for additional development in, for example, language proficiency, mathematical literacy, computer skills and life skills,” says Mr Marais.

Based on their level of achievement in the final Grade 12 examination (Senior Certificate), students will be referred to the foundation programme.

In order to improve students writing and reading abilities for higher education studies, foundation programme students will be offered academic language courses in English and Afrikaans.

Kovsie Counselling will render appropriate services, eg career guidance and support to these students.

The new foundation programme will be implemented in the faculties of Natural and Agricultural Sciences, Economic and Management Science, the Humanities and Law.

The duration for this programme differs from faculty to faculty. In the Faculty of Law it will take five years, while in the faculties of the Humanities, Natural and Agricultural Sciences, and Economic and Management Sciences it will take four years.

The national Department of Education will fund the foundation programme for three years. Funding for such programmes was made available to all higher education institutions in South Africa.

The welcoming function for all new first-year students and their parents will take place on Saturday 15 January 2005 at 11:00 in the Callie Human Centre on the main campus in Bloemfontein.

The registration of first-time entering first-year students who applied before 30 November 2004 to study at the Bloemfontein campus will take place from Monday 17 January 2005 to 21 January 2005 at the Callie Human Centre.

Senior undergraduate students (that is, students entering their second or later year of study) may register from 22 to 29 January 2005.

Postgraduate students, first time entering first year students and other students who applied for admission to the main campus after 30 November 2004 must register at the Callie Human from 31 January 2005 to 4 February 2005.

Due to the limitations placed by government on student numbers, the applications of students who applied late will be regarded as pending and will be processed as places become available.
