Initial expectations about the interactive affordances of VR were often inspired by science fiction and technological fantasies rather than based on actual technical possibilities. In these futuristic accounts of VR, interactors would have the opportunity to fully engage with the characters that inhabit the story world, in ways that would feel so natural that it would be indistinguishable from reality. In ‘real’ reality however, the actual production of VR has turned out to be considerably more complicated. To provide a realistic impression of the actual possibilities of VR, this study presents four widely acclaimed contemporary VR experiences (Wolves in the Walls, The Line, Down the Rabbit Hole and A Fisherman’s Tale) and reviews them from a media theory and communication science perspective. We discuss whether and how the concepts identification, parasocial interaction, ‘breaking the fourth wall’ and spatial and narrative presence can still be applied to these VR case studies, eventually aiming to contribute some rudimentary insights into the range of possible media conventions that narrative VR may contain.
Fouling plays a major role in the Dairy industry. Five criteria: defined flow, no circulation, real factory product, defined product temperature and defined wall temperature, are used to review articles on this topic published between 2003 and 2020. To show the effect of those criteria in experiments, a simulation model is developed. For a good experimental design to measure fouling, the use of a dairy product in a tubular heater with a known developed flow is advised. The temperature-time history of the product and the wall temperature of the heater should be recorded. Circulation of a product will increase the fouling and decrease the flow. Although none of the reviewed articles complied to all criteria, 71% of the reviewed articles met at least two criteria. If not all criteria are met, the results are of less use for the application for process lines on industrial scale. A simulated computer model can be helpful.
