Summary: Heuristics give some general principles or reflections that should be taken into account when an interface is being developed. Heuristic evaluation should end with a set of recommendations or advices directed to the responsible of the application or web site. Interaction patterns have reached a certain level of maturity. Designers and developers are offered different pattern catalogues that help them to design usable interfaces and better interactions. In this paper, a method to use interaction patterns in heuristic evaluation is proposed. The idea is to establish a correspondence between each heuristic and one or more interaction patterns. After presenting this correspondence, the paper illustrates the concepts by showing a real case.
