There are many reasons for poor healthy eating practices like behaviour and culture, and technology offers a platform that can be used by adults to promote better eating practices (Gov.uk, 2017). Therefore, the aim of the project is to design an interactive application for adults to promote healthy eating practices at home. Firstly, secondary research is conducted to learn how current mobile technologies are used to promote healthy eating practices and how successfully they do so. Secondly, Design Thinking, which is a user-centred design (UCD) approach, is deployed to find user needs with activities like quantitative and qualitative user studies. Thirdly, two prototypes, which are a low-fidelity (loFi) prototype and an interactive prototype, are developed that aim to explore the possibilities mobile technology has to offer to address those needs. Next, three user studies, two of which are qualitative user studies and one quantitative user study, evaluate the two prototypes. Afterward, the data from the evaluation is analysed and organised into themes. Next, a discussion takes place that provides insights into why current interactive applications aren’t of the highest quality. Furthermore, the discussion also covers the appropriateness of Design Thinking to meet users needs, and the rigorousness required with tools such as the mobile application rating scale to elevate healthy eating applications to higher levels of quality. ‘Future Work’ outlines and prioritises work that could be done to the interactive prototype developed to improve on its current state. To conclude, Design Thinking was acknowledged as a suitable methodology for designing an interactive application for adults to promote healthy eating practices. Design Thinking is suitable because progress was made towards meeting the three objectives set at the beginning of the project.
