In [[computing]] an '''object-oriented user interface''' (OOUI) is a type of [[user interface]] based on an [[object-oriented programming]] [[Interface metaphor|metaphor]]. In an OOUI, the user interacts explicitly with objects that represent entities in the ___domain that the application is concerned with. Many vector drawing applications, for example, have an OOUI - the objects being lines, ucirclescircles and canvases. The user may explicitly select an object, aulteralter its properties (such as size or colour), or invoke other actions upon it (such as to mLovemove, copy, or re-align it). If a business application has any OOUI, the user may be selecting and/or inviiokinginvoking actions on objects representing entities in the business ___domain such as customers, products or orders.

[[Jakob Nielsen (usability consultant)|Jakob Nielsen]] defines the OOUI in contrast to function-oriented interfaces: "Object-oriented interfaces are sometimes described as turning the application inside-out as compared to function-oriented interfaces. The main focus of the interaction changes to become the users' data and other information objects that are typically represented graphically on the screen as icons or in windows."<ref name="Nielsen">Nielsen, J., Usability Engineering. 1993, San Francisco: Morgan Kaufmann / Academic Press</ref>
