“…The cognitive rule that the F + C interaction technology is based on is: When people are in the exploration of the focus information and detailed information that they have interest in, they often need to keep the visibility of the whole information space, especially the visibility of the context information related to the focus (Autarky and Aggravate, 2015). The information visualization has different focus of interest from the scientific computing visualization, and the information visualization takes the abstract information in the data as the main object of visualization, by the establishment of the interactive visual representation in accordance with the cognitive psychological image, to assist people to carry out exploration on the rules and knowledge that is hidden in the complex data (Area, Coquet, Ortega, López and Rodríguez-Ascariz, 2012). When the users are carrying out the mining in the visualized interface that presents largescale data, their cognitive psychology tends to have exploration on the local detailed information that they are interested in, and at the same time, keep the visibility of the overview of the information space at any time (Area, Coquet, Ortega, López and Rodríguez-Ascariz, 2012).…”
