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.

First-year students encouraged to attend UFS welcoming function

2005-01-12

The University of the Free State (UFS) will host a welcoming function for all new first-year students and their parents on Saturday 15 January 2005 in the Callie Human Centre on the main campus in Bloemfontein.

The function starts at 11.00 and will be addressed by the Rector and Vice-Chancellor of the UFS, Prof Frederick Fourie. UFS staff will also be available to provide vital information to first-year students on academic matters.

According to UFS Registrar, Mr Vernon Collett, Saturday’s welcoming function can assist students and parents by providing vital information on the many high quality academic learning programmes on offer at the UFS in six faculties.

“If students and parents have this information it will make the registration process which starts next week Monday 17 January much smoother,” Mr Collett said.

The UFS has split the registration process into various categories of students and Mr Collett appealed to all students to adhere to the dates and times which apply to them as a one-stop service will be available so as to avoid unnecessary delays in the registration process.

The registration of first-time entering first-year students who applied before 30 November 2004 to study at the Bloemfontein campus will take place from Monday 17 January 2005 to 21 January 2005 at the Callie Human Centre.

Senior undergraduate students (that is, students entering their second or later year of study) may register from 22 to 29 January 2005.

Postgraduate students, first time entering first year students and other students who applied for admission to the main campus after 30 November 2004 must register at the Callie Human from 31 January 2005 to 4 February 2005.

Due to the limitations placed by government on student numbers, the applications of students who applied late will be regarded as pending and will be processed as places became available.

Vista campus

The Vista campus in Bloemfontein – which was incorporated into the UFS in January 2004 – no longer accepts applications from first-year students. Such prospective students had to apply to the UFS main campus.

Students who had been registered as Vista students last year must register at the Vista campus on the same dates as applicable on the main campus.

Qwaqwa Campus

At the Qwaqwa campus of the UFS, all first-time entering first-year students must report on 17 January 2005, after which the registration of these students will take place according to a specific programme.

The official welcoming functioning for new first-years at the Qwaqwa campus of the UFS will take place on Saturday 22 January 2005 at 11am in the Rolihlahla Mandela Hall on the Qwaqwa campus. As on the main campus, this function will also be addressed by the Rector and Vice-Chancellor, Prof Fourie.

Mr Collett appealed to first-year students who have applied to study at the Qwaqwa campus and their parents to attend this function which fulfills the same role as the one held on the Bloemfontein campus.

Detailed information on the dates and times of registration for the various faculties and academic learning programmes is available on the UFS website: http://www.uovs.ac.za/content.php?cid=9

Prospective students may also call 051-401-3000 for more information.
