ABSTRACT
This chapter describes the wearable product design process for the group of products that are worn on the head and face, highlighting unique challenges and requirements, and describing practical sizing and design approaches through examples. The head and face area are home to all five of the human sensory organs: the eyes, the nose, the tongue, the ears, and the skin. In addition, the head houses the brain, one of the most important vital organs. It is therefore understandable that products designed to protect, enhance, or monitor human sensory performance or status are head and face worn. Furthermore, head and face-worn products are more likely than products in other areas to require being located within a small proximity of the sensory organs, especially the eyes and ears. This means head and face wearable design has special challenges. This chapter discusses the challenges and how to best accommodate them using the sustainable product evaluation, engineering, and design process (SPEED) approach.
