摘要： A method enables analysis of (e.g. bioelectric) signals acquired by measurement. The method provides N signals U for an observation space and each has a time- and space-dependent signal characteristic U. Digitized signals for a time period T have M time points and define an M×N matrix with M tuples of N signal values each. Signal values acquired at time t form an N-tuple Ūt=(U1, . . . , UN)t in a signal space. The method acquires all combinations of k tuples from the M tuples, and calculates distances between all tuples. Distance values are calculated and define edge lengths of a (k−1) simplex (SIM) with one simplex assigned to each combination of k time points. Quantity characteristics of the simplex (SIM) are encoded into color values (COL), and displays the colors in a combinatorial time lattice (CTL). Each lattice point (GP) is displayed with the color encoded for the assigned simplex.

摘要： An apparatus and method of encoding eye movements and eye tracking data (DAT), represented as time and space parameters (t, x, y) obtained by an eye tracking device and assigned each to a viewpoint (A, B, C, D, E . . . ). Pairs of numbers (Z0,Z1; Z0,Z2; Z0,Z3 . . . ) are taken from the groups of numbers and are combined with each other to obtain for each combination a value (W) that indicates at least a spatial distance (S) between two viewpoints (E, C), wherein the obtained values (W) represent an encoding of the eye movement and eye tracking data (DAT). Preferably the values (W) are determined and stored in form of a first matrix (M) or array. The matrix is subjected to one or more operations (smooth filtering, anisotropic filtering, threshold filtering, anisotropic diffusion) such that the resulting matrix represents an encoding of fixations, saccades and smooth pursuit of a raw data scanpath.
