contact state at the interface of a transparent material can be observed based on the total reflection principle of light by using an image processing technique. To investigate the relationship between contact status and contact force in pre-sliding friction, an optical experimental method is presented in this paper. However, the change in contact state caused by static friction may decrease positional accuracy and control precision. The pre-sliding regime is typically neglected in the dynamic modelling of mechanical systems. For design practitioners, our results indicate the importance of providing the trade-off-transparency design feature to potential consumers. Theoretically, this study increases our understanding of how the design of an RA interface can improve consumers’ product diagnosticity and enjoyment, and proposes two antecedents to improve perceived decision quality and reduce perceived decision effort. In an experimental study, we find that: 1) the trade-off-transparency feature significantly affects perceived enjoyment and perceived product diagnosticity 2) perceived enjoyment and perceived product diagnosticity follow an inverted U-shaped curve as the level of trade-off transparency increases 3) although users spend more time understanding attribute trade-offs with the trade-off-transparency feature, they are more efficient in selecting a product 4) perceived enjoyment simultaneously leads to better perceived decision quality and lower perceived decision effort and 5) perceived product diagnosticity leads to better perceived decision quality without compromising perceptions of decision effort. Further, based on the Stimulus-Organism-Response model, we develop a theoretical model that extends the Effort–Accuracy Framework by proposing perceived enjoyment and perceived product diagnosticity as two antecedents for perceived decision quality and perceived decision effort, respectively. We also examine the extent to which the trade-offs among product attribute values should be revealed to the user. trade-off-transparency feature) to improve consumers’ perceived product diagnosticity and perceived enjoyment.

We investigate a novel design for an RA interface that enables it to interactively demonstrate trade-offs among product attribute values (i.e. Far less understood is the influence of specific design attributes of the RA interface on decision making and other outcome measures. That recommendation agents (RAs) can substantially improve consumers’ decision-making is well understood.
