A simplified user interface (SUI) is an illustration of a software interface that reduces irrelevant information to abstract shapes to create a "stylised but instantly recognisable image" that conveys the contextually important details.[1]
Similar in look to wireframes, SUIs have uses in marketing,[1] user onboarding (for instance by Slack[2] and Google Analytics[3]), and technical communication.[4][5]
As well as improving the speed and clarity of communication, for those creating documentation SUIs offer a degree of future-proofing against incremental changes to the interface,[1] and aid the translation of documents into other languages.[6]
