Examining the gaps among the views of relevant social groups can identify such issues and ultimately lead to more useful designs. Our framework for guiding the needs assessment and design of handheld technologies for museums (see the discussion of Handscape in the case study below) was interpretivism.

These statements highlight the potential for patrons to download and bring information home with them—through the development of automated, seamless systems that electronically send relevant information to visitors on completion of their visit to a museum, for example. 2 shows how the three stakeholders—museum professionals, system designers, and museum patrons—ranked eight objectives for enhancing the museum experience with mobile technologies.
