compensatory tracking

in ergonomics, a tracking task requiring the operator to use a control (e.g., a joystick) to compensate for the movement of a cursor or other indicator on a display so that it remains within a defined target area.

factor method

any means by which latent variables (factors) are extracted or identified in factor analysis. Widely used factor methods include principal components analysis, which seeks to find a set of linear combinations called components that help explain the correlations among variables; and principal-axis factor analysis, in which underlying dimensions or factors are sought to explain the correlations among variables after separating out communality and putting aside the error variance in a set of variables.
