Day 2

Keynote Presenter: Johann Louw,
Organisation: Virtual Reality Laboratory, University of Pretoria
Presentation: Virtual reality: Turning big data into information through visualisation

Johan Louw has a BEng (Mining Hons) from the University of Pretoria. He is the manager of the University of Pretoria’s world class Virtual Reality Centre. The centre strives to be an innovative resource for bringing real-world scenarios to learners to enhance their exposure to their chosen industry; and also allows technical and other practitioners to simulate plans and designs in a risk-free environment with minimal time and resource allocation. Louw will be detailing how exposure to an immersive experience which portrays data visually, makes it easier for project managers to make decisions and improve on their project designs and other activities that operationalise their strategies. There are numerous operational benefits to be gained from interpreting and portraying actual data in the high-quality and realistic visual format offered by the Virtual Reality Centre. Operational productivity, overall effectiveness, and long-term and socio-economic consequences can be visualised by playing out different scenarios before committing resources. Incidents impacting operational risk can be minimised when one can simulate activities without actually exposing people or equipment to harm, and virtual reality also allows multiple data sets to be converted into strategic business information.
