Designing User-friendly Medical AI Applications - Methodical Development of User-centered Design Guidelines

Medical artificial intelligence (AI) applications will become increasingly relevant in the future and change the medical technology market. Areas of application are located in the professional as well as in private use. The human-machine interface (HMI) is crucial for a successful use of these AI technologies and for a high user added value. The factors of user experience, usability and joy of use significantly determine the quality of an HMI, but are still insufficiently researched for medical AI applications. This work addresses this gap and provides generally applicable design guidelines to AI-based mobile medical applications. For this purpose, a user-centered requirements analysis was conducted to evaluate possible HMI concepts for a fictitious medical AI application. Based on these findings, specific design guidelines for the HMI of the fictitious application were established. Finally, a universal design catalog for medical AI applications was developed.
