Prof Lizette de Wet
Prof Lizette 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.

“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 Digital Doorway project will change lives in Heidedal

The combined effort of ICTISE (ICT Innovation in School Education), Reach and the Heidedal community saw a four-station Digital Doorway (computer system) being placed on the premises of Reach at the end of 2010. ICTISE is a programme of the University of the Free State (UFS) and operates from the university’s South Campus. This computer system will allow all Heidedal schools and community members to have free access to computers.

Prof. Jonathan Jansen, Vice-Chancellor and Rector of the UFS, opened the Digital Doorway by cutting a ceremonial ribbon with the assistance of one of the community’s learners.

The Digital Doorway concept originates from a joint initiative between the Department of Science and Technology and the Meraka Institute of the Council for Scientific and Industrial Research. The Digital Doorway consists of four screens and allows access to select content, including open-source application software. This includes audio books, subject textbooks, encyclopaedia, educational games such as “touch maths” and quizzes as well as useful information for school subjects and a newspaper especially for children.

The Heidedal Digital Doorway is the first of its kind in the Motheo District. Typically, one or two kids will be working on each of the computers, while up to five other learners will be giving instructions, allowing the whole group to learn. The Digital Doorway is a smart way of bridging the digital divide, bringing science and technology to our community and opening the doors of learning. ICTISE will support the Heidedal schools to make full use of this new facility by training teachers and community members.

“The UFS hopes that this project will change the lives of the Heidedal community by providing the youth with an opportunity to be in line with the changing world of technology,” said Ms Sarietjie Musgrave, Head: ICTISE.
