Standard query tools have a number of serious usability limitations, as they often rely solely on numerical approaches when dealing with spatial information. The qualitative reasoning community has addressed this issue, by providing powerful formalisms based on the way that humans deal with spatial information, however, integrating these methods into numerical systems raises a number of new Computer-Human Interaction (CHI) problems. This paper addresses three key CHI challenges when combining qualitative and numerical methods: (1) managing the subjective, ambiguous nature of qualitative terms, (2) providing a powerful, yet simple query system, and (3) effectively visualising a complex, fuzzy qualitative query solution. A qualitative GIS called TreeSap is presented, which demonstrates that, with the use of CHI principles, query tools can be bothpowerful and accessible to non-expert users. 收起
