Feedforward in Interaction: A Case Study of Feedforward for a Glimpse of its Potential in Interaction Design

Lee, Woohun; Park, Richard Chulwoo

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.
