Table 1 Some CRP textures and their meanings

From: Gaze collaboration patterns of successful and unsuccessful programming pairs using cross-recurrence quantification analysis

TextureMeaning
Fading portions to the upper left and lower right cornerData is non-stationary, i.e., data has slowly varying parameters
Single and isolated recurrence pointsReflect random and strong fluctuations in the data but are not considered a unique sign of chance or noise
Horizontal/vertical lines and rectangular clustersMarks a time length which a state does not change or changes very slowly or the process is halted at a singularity in which the dynamic is stuck in paused states (called “laminar” or “trapped” states)
Bands of white spaceIndicate abrupt changes or transitions that may reflect an underlying state changes
 Two collaborators uninterruptedly looked at two different spots on the screen
Empty regionsThe states within this period do not occur at any other times (e.g., states are unique or far from normal)
Diagonal lines parallel to the main diagonalSegment of one trajectory runs almost parallel to another segment (i.e., the trajectories visit the same region of the phase space at different times)
 Collaborators looked at the same spot on the screen continuously
