Informing users about the correct hazard level associated with products can be one of the most important measures to help promote user safety while they handle hazardous household chemicals. The aim of this paper is to present pilot study's results about the effectiveness of using a VR-based methodology to examine the influence of a container's features (e.g., shapes) on the users' perception of hazardousness. Previous works have mostly used 2D drawings for this type of study. Issues which may compromise the quality of future experiments: e.g., adequacy of VR devices, interaction quality, simulatorsickness, procedure and quality of the instruments (i.e., questionnaires) are discussed. Despite the fact that the key experiment has not yet been completed, very promising results have been obtained, suggesting that the VR simulator and the methodology adopted may provide a successful evaluation of the packages' hazardousness.
Recent years have shown an increase in the importance of emotions applied to the Design field -Emotional Design. In this sense, the emotional design aims to elicit (e.g., pleasure) or prevent (e.g., displeasure) determined emotions, during human product interaction. That is, the emotional design regulates the emotional interaction between the individual and the product (e.g., robot). Robot design has been a growing area whereby robots are interacting directly with humans in which emotions are essential in the interaction. Therefore, this paper aims, through a non-systematic literature review, to explore the application of emotional design, particularly on Human-Robot Interaction. Robot design features (e.g., appearance, expressing emotions and spatial distance) that affect emotional design are introduced. The chapter ends with a discussion and a conclusion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
