Perceived-Value-Centered Mobile Interaction Design

Interaction design experienced System-centred, User-centred and Context-centred stages. Currently, those theories are all facing difficulties to some extent. Value-centred interaction design could be a good solution for more and more complicated design problem. To represent and deliver the value, the research qualitative and quantitative theorize the value-model: the value is the perceived value of user, including function value, emotional value, society value, conditional value, epistemic value, the interaction of system and the content of interaction. The dimensionalities of delivery are effectiveness and efficiency.Design is a complicated issue, and current design research is normally using qualitative methods, for example interview, observation, and documentation reading. Furthermore, because interaction design involves human, a complex system, it is a challenge to do quantitative research on it. Combining Design, Marketing and Psychology methodologies, and this research explores quantitative research on the fussy concept; user's perceived value on interaction design. Qualitative research can help design understand the big picture; quantitative research is helpful to legibly and rationally guide the interaction definition, design and assessment. However, quantitative research is not everything for design. Quantitative and qualitative methods are based on different assumptions and can not be simply combined. The innovation point in this research is to conduct qualitative research on perceived-value-centred theories and build value formation model according to behaviour theory and mean-end chain theory, and come to a conclusion that user perceived value should be the leading value in interaction design, and get value dimension system and further scale evolution borrowing classical Ergonomic theory. Using mobile interaction as an example, through design and sales theories, we present Value Model hypothesis and use psychological scale measurement to verify it, and build interaction design specific user perceived value model by combining quantitative and qualitative methods, and therefore present our new ideas about future interaction design.
