Designing the Star User Interface

‘User-interface design is still an art, not a science. Many times during the Star design we were amazed at the depth and subtlety of user-interface issues, even such supposedly straightforward issues as consistency and simplicity. Often there is no one 'right' answer. Much of the time there is no scientific evidence to support one alternative over another, just intuition. Almost always there are trade-offs. Perhaps by the end of the decade, user-interface design will be a more rigorous process. We hope that we have contributed to that progress.’ (source)
