This product design thesis paper aims to explore innovative strategies for making the process of learning oral and hand hygiene habits more engaging and interactive for children. The study aims to identify effective teaching methods, incentives, and technologies that can be incorporated into product design to promote healthy oral and hand hygiene behaviors in children in a fun and playful way. The research will involve conducting a comprehensive literature review of existing literature on hygiene habits in children, effective teaching methods, and relevant psychological theories on child learning and motivation. The study will also examine how visual elements such as packaging and product design influence the sales of children's toys and what regulations and standards are in place for children's toys, and how corporations comply with them. The data collected from the literature review will be analyzed to identify the most effective strategies for incorporating oral and hand hygiene education into product design. This research aims to contribute to the field of product design by developing a product system that makes teaching healthy oral and hand hygiene behaviors to children more enjoyable and playful. The findings of this study will provide valuable insights into the current hygiene habits and attitudes of children and serve as a foundation for future research in the field of product design and hygiene education.

This project is built around the idea of designing hardware for accessibility. In the modern context, many accessibility solutions are built around software. While this allows for a lot of flexibility in terms of features and content, it is an imperfect approach to design for users of all abilities. In particular, blind and deaf-blind users are poorly accounted for in terms of hardware design. They are a user group that is highly limited by the inadequate features designed for their needs, and this project will demonstrate that users feel frustrated by these imperfect solutions to using a smartphone without sight. Not only will this project present its own accessory to accompany software accessibility features, but this project will also try to push first-party manufacturers to design and create their own hardware solutions. LOUIS is a refreshable braille display that magnetically attaches to a smartphone case. It will give braille users the tools they need to not only operate their phone through hardware, but read and write through braille. It includes a braille display that can read out on-screen information using existing software APIs. It also has Perkins brailler keys for users to compose texts, emails and other messages. It is packaged into a thin and highly-portable package that will allow users to continue to pocket their phones easily.
