Proposition of a Model for Elucidating Emotions: A Tool in Project Development

In the last years, several aspects related to product features other than good operation and usefulness have been discussed, such as the importance of user-product emotional interaction. There was an increase in design studies on this subject in the last years, covering product aspects that trigger emotional responses, however, models regarding these interactions are still in their early stages. Thus, this work presents literature research on Design models and emotion, supplying the development of a model that aids emotional decision making in product experience. The studied models are compared, resulting in a new model. This model is part of a broader research that aims to clarify the role of shape and material in product Design; the other aims of the research – which are not discussed in this article – consist of searching for models for material selection and verbal attributes.
