An effect involving a number of bodies, particles, or systems as a result of which some physical or chemical change takes place to one or more of `them. See also fundamental interactions.
A term particularly used in the contexts of factorial experiments (see factorial design) and log-linear models to describe cases where the combined effects of two variables is not a simple sum of their separate effects. For example, we might write
the final term quantifying the interaction between the two x-variables.
The term used when an operator interacts with a computer by means of a set of input devices to achieve a desired effect. See also acknowledgment, echoing, feedback, prompt.
The action between points, each upon the others; ‘business concentration clearly facilitates more intensive social interaction, and interaction intensity is argued to be a key element differentiating between types of client-supplier relations’ (Bennet et al. (1999) TIBG 24, 4). An interaction model describes the reactions of two or more processes or systems as they affect each other; see Eradus et al. (2002) J. Transp. Geog. 10, 2.
