An interface may receive user input, wherein two or more interactive shapes are shown on the interface, wherein each interactive shape represents a query of scoring an attribute, and wherein a size parameter of a first of the two or more interactive shapes is indicative of the scoring of the represented attribute. The method comprises retrieving a user selection of one interactive shape of the two or more interactive shapes so that the one interactive shape becomes a selected master shape and the remaining of the two or more interactive shapes becomes non-selected slave shapes, retrieving a user request for increasing or decreasing of the size parameter of the selected master shape, and resealing the size parameter of the non-selected slave shapes such that a sum of the size parameters of the two or more interactive shapes is kept at a constant value.
