In recent years, user research has become an important part of the design process, with the emergence of strategies such as inclusive design, universal design, consensus design and participatory design. Also, with legislation and policy developments, user involvement has become an essential element in design (BSI British Standard BS 7000-6). Discussions regarding forms of incentives are taking place in different research areas. For example, in studies of Bioethics, scientists have been asking how much subjects should be paid to participate in research (Latterman and Merz, 2001). For consumer researchers, there are some basic cash incentive formulas. In the USA, for example, people are paid $0.75 for every minute spent doing general consumer research and $1.00 per minute for one-on-one interviews (Kuniavsky, 2003). The aim of this workshop is to foster exchange of experience on user involvement in the design process. During this workshop, a new game called Incentive will be introduced as a research tool for generating discussions on forms of incentives and implementation methods.
