Accommodating users' profile diversity in systems interface projects is a frequent problem for the human computer interface designer. Therefore, user is faced with barriers in the use of interfaces which were not designed for your profile. This work presents a solution for expressing and accommodating users' diversity, which is useful for the HCI designer, especially for those who design families of products. PICAPS are interface design patterns with layers indexed by personas. The interface design patterns support the designer in employing proven solutions, for they represent a recurrent problem and its abstract solution in such a way that this solution can be applied to different instantiations of the same problem. PICAPs are structured in multiple layers to make possible the users' diversity accommodation. The layers are indexed by personas as user's characterization resource. This concept has been applied to electronic government services, because such systems should be usable by any citizen and therefore are a good example of the user diversity problem. A field research with 25 designers has been performed to check the concept's applicability.
