The mental model is a well-known subject discussed by Norman. But problems of everyday things
continue to exist. In fact, it is almost impossible to provide a coherent conceptual model for
individual users, especially when an increasing number of technology-embedded artifacts have
created new interactivities nowadays. In this paper, the classical user interface problem of a gas
stove’s spatial mapping will be used to demonstrate how interactivity could be tamed by using the
concept of feedforward. Feedforward is an important element to consider because it provides clear
and instant affordance, leading to a mistake-free user experience.
This paper discusses feedforward based on the utilitarian perspective. The Previewable system will
be introduced to compare the performance among conventional, touch-enabled, and hover-enabled
gas stoves. Findings from a comparison analysis of its performance, its state of action, and the
subjective experience will be shared. Furthermore, aspects of feedforward open up a venue in
which to discuss its influence on the interpersonal and power relations that exist between artifacts
and users with a design guide. The latent potential of feedforward leaves a lot to be discussed, but
the findings in this paper strengthen the case for feedforward and lead to a glimpse of look at
feedforward in context-aware.
