–squares = salmon (circles = no salmon)
•“Results from our work provide a number of guidelines for the use of hue and form in real-time visualization. Hue can be used to perform rapid and accurate boundary and target detection. Form can be used to perform boundary detection, but it cannot be used as readily to perform target detection if a secondary data dimension is encoded with hue. If a user wants to perform real-time multidimensional visualization, hue should be used to encode the primary data dimension being investigated. Secondary data dimensions can be encoded with form. This will not interfere with boundary and target detection tasks performed using hue.”
