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.

Moshoeshoe Memorial Lecture to focus on Leadership challenges

Lecture to focus on Leadership challenges

n Thursday 25 May 2006 – Africa Day – the University of the Free State (UFS) will host the inaugural King Moshoeshoe Memorial Lecture in honour of this great African leader and nation-builder.

Prof Njabulo Ndebele, internationally renowned writer and academic, and Vice-Chancellor of the University of Cape Town (UCT), will deliver the inaugural lecture at the Main Campus in Bloemfontein on the topic: Reflections on the Leadership Challenges in South Africa.

“I see the lecture as part of a larger debate on leadership models, particularly the concept of African leadership, as well as the ongoing discourse about nation-building and reconciliation,” says Prof Frederick Fourie, Rector and Vice-Chancellor of the UFS.

According to Prof Fourie, the Moshoeshoe project was launched at the UFS in 2004 to coincide with South Africa’s first decade of democracy and was part of the University’s centenary celebrations, having been founded in 1904.

“Through this project the UFS seeks to honour a great African leader and demonstrate our commitment to transformation so as to create a truly inclusive and non-racial university,” said Prof Fourie.

“As the founder of the Basotho nation, King Moshoeshoe is widely credited for his exceptional style of leadership, displaying the characteristics of diplomacy, reconciliation and peaceful co-existence in his efforts to unite diverse groups into one nation,” said Prof Fourie.

As part of its ongoing Moshoeshoe project, the UFS commissioned a television documentary programme on the life and legacy of King Moshoeshoe. This was completed in 2004 and broadcast on SABC 2 later that year.

Previously he served as Vice-Rector of the University of the Western Cape. Earlier positions include Chair of the Department of African Literature at the University of the Witwatersrand; and Pro-Vice-Chancellor, Dean, and Head of the English Department at the National University of Lesotho.

An established author, Njabulo Ndebele recently published a novel The Cry of Winnie Mandela to critical acclaim. An earlier publication Fools and Other Stories won the Noma Award, Africa’s highest literary award for the best book published in Africa in 1984. His highly influential essays on South African literature and culture were published in a collection Rediscovery of the Ordinary.

Njabulo Ndebele served as President of the Congress of South African Writers for many years. As a public figure he is known for his incisive insights in commentaries on a range of public issues in South Africa. He holds honorary doctorates from Universities in the Netherlands, Japan, South Africa and the United States of America. He is also a Fellow of UCT.
