Because the age structure is getting older in Finland, demand for accessible environments and services is growing at an accelerating pace. One service that provides information about accessibility is the ARVI database, which is operated by ARA. The ARVI database is unknown to many and its data is regarded as unreliable.

The aim of this study is to examine how the information the current ARVI database holds could better service the people who would benefit from it and how this material could be used to support the application of building permits and funding from ARA. During the thesis a number of computer-generated prototypes will be built which will be tested with usability testing. How prototypes can be used to get better feedback and more ideas from test users during usability tests will also be examined during the tests.
