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.

The African Student Affairs Conference (ASAC), which took place on our Main Campus last week, was a major success, with two days of lectures and discussions and two pleasant social gatherings, where delegates had the opportunity to get to know each other.

The conference, hosted on African soil for the first time, and co-hosted by the University of the Western Cape (UWC), started on Wednesday 18 May 2011 with an informal welcoming session. Delegates got to meet each other and Mr Rudi Buys, UFS Dean of Student Affairs, explained the meaning of South African words like "kuier" and "lekker'.

The official start of events took place on Thursday 19 May 2011, in the Reitz Hall in our Centenary Complex. The conference was attended by delegates from universities across the continent and aimed to place the focus on issues relating to student affairs in an African context.

Delegates shared and exchanged strategies, ideas and resources, and discussed issues related to the work of student affairs professionals. The conference hoped to promote an exchange of best practice and assist attendees in identifying successful programmes.

Among the topics discussed on the first day, were “Constructing Post-Conflict Democracy on campus: a case study of transformation of student governance and political engagement as post-conflict intervention”, by Mr. Buys, and a discussion on ways in which social and online media can be used to ease the challenges of student interaction, development and support, by Ms Birgit Schreiber, Director of the Centre for Student Support Services at UWC.

A panel discussion, led by Mr Buys and several members of our Interim Student Council (ISC), discussed the specific challenges faced at the UFS. The importance of buy-in from role-players in decisions taken by University management in order to ensure their success, was discussed, using the UFS and our recent changes as an example.

The successful integration of residences on campus inevitably came under the spotlight and the recently resolved Reitz-saga was named as a catalyst in getting students less apathetic and more involved in attempts at creating racial and social harmony.

Dr Christina Lunceford, Assistant-Director of the Centre for Research on Educational Access and Leadership at California State University, presented a paper entitled A National Approach to Building Capacity in Student Affairs in South African Higher Education.

She commented on the fact that there is little or no philosophical framework or explicit theory that informs practice of student services in South Africa.

According to Dr Lunceford, student development should be a key concern for every department or unit within student services and emphasized the need for a centralized student development unit at each university.
She also touched on the need for institutions to implement support from international student affairs professional associations, professional development for student affairs practitioners, the utilization of technology to support professionals in the field, and working with international partners to explore future opportunities, as ways in which student affairs can be used to drive performance and change at universities.

The conference continued in the Scaena theatre on Friday 20 May 2011, with presentations by Dr Augustinah Duyileme, Dean of Student Affairs at Adekunle Ajasin University in Nigeria, and Prof. Bobby Mandew, Executive Director of Student Affairs at the University of Johannesburg (UJ).

Dr Duyileme presented a paper on the challenges faced by Nigerian universities with regard to student conflict and protests, which often turn violent, and how such violence can be curbed through proper planning and management.

Prof. Mandew presented a very well-received presentation on UJ’s successful off-campus housing initiative, which involves home-owners and business owners in the areas surrounding their campuses.

Their approach demonstrated how proper planning can prevent problems associated with over-population in private homes and conflict with neighbours of the university, usually related to an influx of students into residential neighbourhoods.

This problem is faced by many universities, as more and more students flock to universities on the continent and campus residents cannot accommodate them.

The conference came to a close on Friday, with most delegates agreeing that the exchange of knowledge which took place was extremely valuable.

Ms Deborah Lahlan, of Nigeria, said: “This is an important conference for Africa and it should become a regular event.”
