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.

Central SRC constitution for UFS approved by Council

2005-07-20

University of the Free State Fact Sheet

1. The Council of the University of the Free State (UFS) on 10 June 2005 unanimously approved the establishment of a Central Student Representative Council (CSRC) to constitute a legitimate basis for the democratic participation of students of all three of its campuses in the governance of the university.

2. In a major breakthrough and transformation step for student governance, the Central SRC will include representatives of the main campus in Bloemfontein, the Vista Bloemfontein campus and the Qwaqwa campus of the UFS.

3. The need to establish the Central SRC follows the incorporation of the Qwaqwa campus into the UFS in January 2003 and the incorporation of the Vista campus in Bloemfontein into the UFS in January 2004.

4. The constitution of the Central SRC is the outcome of a consensus reached during a lengthy process of negotiation between the SRCs of the three UFS campuses, indirectly involving diverse student formations such as Sasco, ANCYL, YCL, Pasma, SASO, SADESMO, AZASCO, SCO, HEREXVII, KovsieAlliance, ACDP, etc. Independent constitutional and political experts facilitated key parts of the negotiation process.

5. In this process, the UFS management went out of its way to ensure the participation of all student formations, especially Sasco and the ANC Youth League, as well as the duly elected SRC officials of the three campuses.

6. With the establishment of a Central SRC, the UFS has adopted a federal student governance model whereby the CSRC is the highest representative student body on matters of common concern for all students. The three campuses of the UFS will retain SRC structures for each campus with powers and responsibilities for matters affecting the particular campus.

7. The central SRC will have 12 members made up of delegates of the different campus SRCs, including the presidents of these three SRCs. In total, the main campus will have 5 representatives, the Qwaqwa campus will have 4 representatives and the Vista campus will have 3 representatives. This ratio ensures a strong voice for the smaller campuses in the central SRC.

8. This arrangement will be reviewed after a year to make allowance for the phasing out of undergraduate (pipeline) students at the Vista campus, as was agreed in the negotiations preceding the incorporation of that campus into the UFS.

9. From these 12 members a central SRC president will be chosen on a quarterly basis to represent the general student body at Executive Management, Senate and Council.

10. The historic official inauguration of the first Central SRC is scheduled to take place in early August 2005.

11. This event, like the adoption of a broadly negotiated new constitution for the main campus SRC, represents a breakthrough in that all three campus SRCs delegations and all relevant student organizations have been part of the process and have accepted the outcome of the process.
