Super high definition three-dimensional display environment applied to visual data mining

Recently, the quantity of accessible data continues increasing, and the importance of data mining is also increasing. On the other hand, highly developed computing facility enabled visual data mining in immersive environment. Visualization has an important role in current data mining, and the rapid progress on visualization devices, such as super high definition stereo display, can enhance the existing data mining scheme. Super high definition stereo displays can represent amount of information to the users. But it does not mean that the information is conveyed correctly to the users. In this paper, we conducted experiments on human perception, and the results suggest human cognitive limitation is no longer ignorable in visual data mining. We developed visual data mining platform focusing on point cloud representation, and it was applied to visual data mining on seismic data.
