The methodology is consisted of sequentially performing: a competitive analysis, user task analysis, heuristic evaluation, formative evaluation, and finally a summative comparative evaluation. We first described each of tWe found that ourThe user-centred methodology could have a major impact on improving the usability of IR user interfaces. This proves the efficacy of our user-centred methodology. We hope this methodology wouldThis methodology provides a starting point for techniques that let IR researchers and practitioners to design better user interfaces that is are both easy to learn to use and remember.enUser-centred designUsabilityHCIIRUser interfaceArticle
