Abstract
To address the question, "How might the products be designed to evoke curiosity in users?" the concept of curiosity and the five main principles of evoking curiosity were investigated. The various approaches to apply the broad concepts of curiosity to product design, as well as their constraints and limitations, were examined using an iterative design research technique. The newly translated concepts for developing inquisitive items were then validated by applying them to the product and interaction design of two products (an audio system and a soap dispenser). The audio system's interactions were carried out using embedded machine learning. The effectiveness of the audio system to evoke curiosity in users and its usability are studied with user testing.
