From the user interface designer's perspective, an interaction technique is a well-defined solution to a specific [[user interface design]] problem. Interaction techniques as conceptual ideas can be refined, extended, modified and combined. For example, [[contextual menu]]s are a solution to the problem of rapidly selecting commands. [[Pie menus]] are a radial variant of [[contextual menu]]s. [[Marking menu]]s combine pie menus with [[gesture recognition]].

Interaction techniques are usually fine-grained entities. For example, a [[desktop environment]] is too complex to be an interaction technique, whereas [[Exposé (Mac OS X)|Exposé]] fits the common intuitive understanding of the term perfectly well. Also, a graph may have a large disparity between the lowest and highest values along the [[Y-axis|Y-Axis]] and unable to display clarity, so the [[Harrison Curve]], some what similar in nature to a standard linear zoom, allows the user to distort the focual area to their benefit {{Clarify|date=March 2012}}. In general, a user interface can be seen as a combination of many interaction techniques, some of which are not necessarily as explicit as [[GUI widget|widgets]].

Interaction techniques that share the same [[Interface metaphor|metaphor]] or design principles can be seen as belonging to the same [http://www.interaction-design.org/encyclopedia/interaction_styles.html interaction style]. General examples are [[Command line interface|command line]] and [[direct manipulation]] user interfaces.
== Interaction patterns ==
While interaction techniques are typically technology-, platform-, and/or implementation-dependent (see [[#levels]] above), human-computer or human-information interactions can be characterized at higher levels of abstraction that are independent of particular technologies and platforms. At such levels of abstraction, the concern is not precisely how an interaction is performed; rather, the concern is a conceptual characterization of what the interaction is, and what the general utility of the interaction is for the user(s). Thus, any single interaction pattern may be instantiated by any number of interaction techniques, on any number of different technologies and platforms. Interaction patterns are more concerned with the timeless, invariant qualities of an interaction.<ref name="sp">Sedig, K. & Parsons, P. (2013).
