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.

Kovsie Tennis team defends proud USSA record in Cape Town

Duke Munro already has six gold medals from the USSA Tennis Tournament in his cupboard, and the Kovsie Tennis team would wish to bid him farewell in a fitting manner during what will probably be his last tournament in Cape Town.

This year's tournament, taking place from 30 November to 4 December 2015, will probably be Munro's last, since he is completing his Master's degree in Quantity Surveying at the University of the Free State (UFS).

He has competed in the USSA Tournament since 2009, and would like to help his team defend its proud record.

UFS aim for ninth consecutive title

Kovsies have won gold at the USSA Tournament for the last eight years. They are the only team who have been able to win the tournament since the combined format was adopted in 2010. In 2007 and 2008, their Women's team won the tournament, and in 2009, their Men's team.

Kovsies will play in group matches against the Universities of Venda and Wits on 30 November 2015, against the University of Cape Town's (UCT's) second team on 1 December 2015, and against UCT's first team on 2 December 2015. The cross and knockout matches will be played on 3 and 4 December 2015.

Other sporting codes

The Sevens Rugby team from the UFS will compete in the USSA Tournament in George on 30 November and 1 December 2015.

For the past two years, the team has won bronze, and will be playing three league matches on 30 November 2015 against the North-West University's Vaal Campus, Nelson Mandela Metropolitan University's Port Elizabeth Campus, and the Vaal University of Technology.

Kovsies are the current Varsity Sevens Champions after winning the title in Cape Town in April 2015.

Ten Kovsie swimmers took part in the USSA Tournament in Johannesburg from 28 November to 30 November 2015. Last year, Kovsies came third, but unfortunately some of their leading swimmers were unable to take part this year.

The Kovsie Table tennis team will participate in the USSA Tournament in Kimberley from 30 November to 4 December 2015.

Most of the USSA Tournaments in the other sporting codes were either postponed or cancelled because of the recent nationwide student protests. As a result of the protests, exams were written later, and tournaments would have taken place during the holidays.

Only the tennis, table tennis, Sevens rugby, swimming, and cricket B Division in East London will continue.

The USSA Soccer Tournament, to take place at the UFS and the Central University of Technology in Bloemfontein, was postponed until March 2016.
