“…In our case, data visualization is presented to the user with the help of an interactive and fully immersive Virtual Reality (VR) interface. A previous exploratory and qualitative study carried out using the first version of IPCP demonstrated that users were able to successfully detect patterns in high-dimensional datasets visualized as-is [2][3][4], that is, without any prior analysis or data cleaning, using the IPCP system (see Figure 1) combined with a simple naive clustering algorithm applied to cross-dimensional 3D scatter plots data [2][3][4]. However, this basic IPCP system allowed users to rediscover the knowledge; specifically, patterns with the data items previously found by the domain experts and, more importantly, users were able to discover new knowledge in the dataset compared to original analyses carried out by experts using a more traditional 2D PCP system [3,4].…”
