Editing Interaction design (section)

===Goal-oriented design===
Goal-oriented design (or Goal-Directed design) "is concerned with satisfying the needs and desires of the users of a product or service."<ref name="AboutFace3" />{{rp|xxviii|location=31}}

[[Alan Cooper (software designer)|Alan Cooper]] argues in ''The Inmates Are Running the Asylum'' that we need a new approach to solving interactive software-based problems.<ref name="Inmates">{{cite book |title=Inmates Are Running the Asylum, The: Why High-Tech Products Drive Us Crazy and How to Restore the Sanity |last=Cooper |first=Alan |year=2004 |publisher=Sams Publishing |isbn=0-672-32614-0 |pages=288 }}</ref>{{rp|1}} The problems with designing computer interfaces are fundamentally different from those that do not include software (e.g., hammers).  Cooper introduces the concept of cognitive friction, which is when the interface of a design is complex and difficult to use, and behaves inconsistently and unexpectedly, possessing different modes.<ref name="Inmates"/>{{rp|22}}

Alternatively, interfaces can be designed to serve the needs of the service/product provider. User needs may be poorly served by this approach.
