Definition

Dense Pixel Displays are a visual data exploration technique. Data exploration aims at analyzing large amounts of multidimensional data for detecting patterns and extracting hidden information. Human involvement is indispensable to carry out such a task, since human’s powerful perceptual abilities and domain knowledge are essential for defining interesting patterns and interpreting findings. Dense pixel displays support this task by an adequate visual representation of as much information as possible while avoiding aggregation of data-values. Data is shown using every pixel of the display for representing one data point. Attributes of the data are mapped in separate sub-windows of the display, leaving one attribute for one sub-window....
