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.

A time to celebrate: Autumn graduations

2016-04-07

General graduation information
Livestreaming

The first series of graduations for the year are upon us. Graduates from all seven faculties, the Business School, and the School of Open Learning at the University of the Free State (UFS) will be celebrating their academic achievements. A total of 3681 qualifications will be conferred at ceremonies on the Bloemfontein Campus from 12 to 15 April 2016.

Sejakhumo Makhetha, daughter of our Vice-Rector: Student Affairs and External Relations, Dr Choice Makhetha, will be among the graduates receiving BA Governance and Political Transformation degrees. Coincidently, Dr Makhetha obtained her PhD in Political Science in 2003 at the UFS. Sejakhumo Makhetha is currently busy with her postgraduate diploma in the same field.

The four-day celebration symbolises the UFS prerogative as an institution to transform lives by producing leaders of tomorrow. Dr Muavia Gallie, Dr Sello Hatang, Dawie Roodt, and Nikiwe Bikitsha are expected to address these future leaders and guests at these ceremonies.

Addressed by the best

On the guest speaker line-up, we have Dr Gallie, a School and District Turnaround Strategist and education activist, who has been identified as one of the 10 Most Impressive Public Leaders for 2015 by the UFS Vice-Chancellor and Rector, Prof Jonathan Jansen. The former Head of Operations, Human Resources and Information and Communication Technology at the South African Council for Educators (SACE) has had more than 30 years of experience in education.

Dr Gallie and Dr Hatang will address graduates of the Faculties of Education, Health Sciences, Law, and Theology on 12 April 2016. Dr Hatang is the Chief Executive of the Nelson Mandela Foundation. In addition to being a founding member of the Advisory Council of the Council for the Advancement of the South African Constitution, Hatang has had the privilege of serving as the Head of Information Communications, and spokesperson for the South African Human Rights Commission as well as Director: South African History Archive at Wits University.

Dawie Roodt, founder, director, and chief economist of the Efficient Group, will speak at the Faculty of Economic and Management Science ceremony on 14 April 2016. This nationally-renowned economist boasts 30 years of experience in monetary and fiscal policy, and is one of the most referenced authors. In 2013, he published Tax, Lies and Red Tape.

As one of South Africa’s leading journalists, Nikiwe Bikitsha will draw on her 20-year career in radio, television, and journalism to address the Faculty of the Humanities graduates on the final day of graduations. Through her passion for Africa’s economic development and women empowerment, the co-founder and CEO of Amargi Media has been a successful Programme Director for UN, IMF and AU-related events.
