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]].
=== Level of granularity ===
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]].
