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.

Taking the human being into consideration is much more important than simply concentrating on the programming code that needs to be written.– Prof Lizette de Wet

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.

This year’s TEDxUFS speaker lineup persuaded the audience unanimously to question the nature of reality. The Albert Wessels Auditorium on the Bloemfontein Campus was packed with about 200 attendees on Saturday 1 August 2015.

Speakers shared a multiplicity of profound theories and inquisitions, challenging society in general to think out of the box. Melody Mentz, Gil Oved, Ricardo Peach, Pamela Nomvete, Pepe Marais, Mmusi Maimane, Brian Kally, Pieter Geldenhuys, Philippa Tumubweinee, Gareth Cliff, and Angelo Mockie took on to the stage to tackle multidisciplinary concepts as part of the broad ‘Ask Why’ theme.

Innovation mouthpieces share their worldview

Pieter Geldenhuys, the internationally-renowned futurist and Director of the Institute for Technology Strategy, and Innovation proposed that we change our mindsets by neglecting predictability. “We need to look at different models to understand the world around us,” he said. He challenged the linear and familiar ways humans make sense of the universe.

Speaking to the dire need for transformation, Philippa Tumubweinee suggested that university spaces merge with the communities they serve in terms of policies, social atmosphere, and physical structure. Tumubweinee is a senior Lecturer at the Department of Architecture at our university, and co-Founder and Director of Izuba In Africa architects.

“Only we can give permission to be intimidated; so don’t give in,” said Brian Kally, the CEO of Arrow Logistics (Pty) Ltd. Kally underscored the power of believing in our individual ideas.

Guidelines from TEDxUFS organisers

Bonginkosi Leeuw: “If you take your brainchild and implement it, and make it a reality, that’s when you can achieve great things, not before that.”

Lerothodi Molete: “You should ask questions; the moment you ask the question you will understand more.”
