Prof Lizette de Wet
Prof Lizette 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.

“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.

The Essop twins bring ‘UNREST’ to the UFS
2015-03-19

 

UNREST, an exhibition by Hasan and Husain Essop, is now at the Johannes Stegmann Art Gallery in the SASOL Library on the UFS Bloemfontein Campus. It will be on until Thursday 2 April 2015. 

The 28-year-old twin brothers are the winners of the 2014 Standard Bank Young Artist Award for Visual Art. Born and raised in Cape Town, they have been collaborating since their graduation from the Michaelis School of Fine Art in 2007. They both completed a Bachelor of Fine Arts degree and a Postgraduate Diploma in Art at Michaelis. Subsequently, they earned Postgraduate Certificates in Education at the University of Cape Town.

Husain specialised in Photography, and makes all the important technical decisions when setting up a shoot. Hasan specialised in Printmaking, and therefore has a lot more freedom in the post-production and printing of the work. They both contribute to the subject matter and editing of the photographs, always discussing new ideas and locations to shoot. They speak very visually to each other, and many ideas are born from their conversations. They draw on popular culture, the media, and Hollywood as inspiration because those are the things that interest the youth and shape the next generation.

“Our series of works highlight a multi-cultural clash between religion and popular cultures,” say the Essops. “We explore the dominating influence of Western theatrics and those narratives that are constructed to depict a certain reality. Inspired by Hollywood’s visual language and tactics, we create our own narratives. Each photograph reflects us in a battle of moral, religious, and cultural conflicts. Two dominant personalities appear, East and West, with all their stereotypes. Environments are chosen as stages on which to perform and define our behaviours.”

The Essops’ work has been included in various private and public collections, including the Spier Collection, the Durban Art Gallery, and the South African National Gallery. The Goodman Gallery has hosted two solo exhibitions of their work – Halaal Art (Johannesburg, 2010,) and Remembrance (Cape Town, 2012,).

The Johannes Stegmann Art Gallery hours are Monday to Friday from 08:30 to 16:30.
