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.

2011 Leadership group meets for the first time

The long application process, panel interviews and nail-biting wait finally came to an end the past week, when the cream of our first-year class of 2011 gathered in the Scaena Theatre on our Bloemfontein Campus, for their first group meeting as the selected Leadership for Change cohort.

These 150 students, from all our faculties, will over the following year be groomed to be leaders, not only at the university, but also in their respective fields and chosen careers.
The first group of students will depart for their respective universities in America and Europe on 22 September 2011, where they will spend two weeks. The second group of students will depart for universities in Japan in January 2012.

Although they have all passed a gruelling selection process, the real hard work is only starting now for these bright young students.

The programme will take place in four phases. During the preparation phase, which has now kicked off, students are prepared for the experience ahead, while being made aware of exactly what to expect from the programme.

In the study-abroad phase, students will be placed at 15 partner institutions in various countries, and will be divided into groups of six to twelve people. According to Prof. Aldo Stroebel, Director of International Academic Programmes, the groups will be diverse, in that there will be a mix of races, genders and study fields, which should guarantee dynamic interaction.

During the group’s first meeting this week, they were informed of the important goals of the Leadership for Change Programme, by Mr Rudi Buys, Dean of Student Affairs.

He imparted the gravity of their selection on the students by saying, “You may not get it yet, but I understand the reason we are all here. I understand that by looking at what you achieve after this programme, we can tell what the country could possibly achieve in the future. It is immensely moving to see the way you all carry yourselves, since I can see something special and unique in each of you.”
“You are all here, not because of which school you went to, or your race, or who your parents are, but because you all show potential to be something great.”

Prof. Stroebel reminded the group that despite the excitement that they all have about visiting universities in America, Europe and Asia, these visits should be seen as study trips.

“You may have three days to acquaint yourselves with the surroundings, but after that there will be very little sightseeing and a lot of hard work.”

They will participate in programmes designed by their respective host institutions, aimed at exposing them to different cultures, lifestyles and beliefs.

They will be accompanied by our staff, who Prof. Stroebel says will grow with the students, as they will be expected to guide the students through their tasks and assignments and interact with them on a daily basis.

Upon their return, there will be a debriefing phase, during which they will be expected to provide feedback on their experiences, as well as submit assignments which they will be assigned at their respective institutions.

The final phase is known as the impact phase, as this will see the students apply what they have learned in a positive manner and help drive the university to the future and to becoming a world-leading tertiary institution.
