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.

Meet the person behind the title – your new FaceOfFacebook

2015-04-29

Kovsies #FaceOfFacebook was born three years ago out of a need to engage with students, and become a virtual friend. Auditions are held every year to choose the new ‘face’ representing the UFS on Facebook. The successful candidate holds the title as #FaceOfFacebook for the next 12 months, attending events, and filming short video clips to post on our Facebook page.

The votes have been counted, and we have a winner. After much excitement and a close contest, Nompumelelo Maseko (whose name, fittingly, means ‘success’) emerged victorious from the top six contestants selected by our panel of judges. We sat down with the soft-spoken Mpumi – as her friends call her – to get a sense of the person who will be our ambassador for the next year.

What is your field of study, and how far along are you?

I am studying for a BSc degree in Genetics, and I’m currently in my second year. I have a particular interest in the forensic sciences, which fascinate me!

Are you originally from Bloemfontein?

No, I am originally from Pretoria.

How is it that you ended up here, studying at the UFS?

Before leaving school, I applied to various universities, but my desires and ambitions brought me here.

How do you find your residence?

Akasia ladies are big on sisterhood, very supportive. Res life is very enjoyable.

What do you hope to accomplish during your term as the #FaceOfFacebook?

I would like to help people become aware of what is taking place on campus. There are many opportunities to be more engaged with what is happening at the varsity. For instance, there are still many people who don’t really know what the #FaceOfFacebook is, and I would like to help inform them about it.

What is your motivation in your studies, in taking part in this contest, and in life?

I am intrigued by the function of life forms, the differences that exist at a cellular level.
For this competition, I fed off my love of people, even though I am shy. I also enjoy presenting.

I have my parents to thank as my motivation, as well as meeting and engaging with people. I find that I achieve a broader perspective when I don’t restrict myself to my own opinions, but strive to be open to differing views.

Nompumelelo will be appearing in one of her first Facebook videos shortly, so be sure to keep an eye on our Facebook page.
