Designing a Mobile App for Managing Alzheimer's Disease: A User-Centered

Alzheimer's disease affects a significant number of people in Thailand, with 10% of those over 65 in the early stages of the condition. The disease can greatly reduce the quality of life for patients and also negatively impact the work performance of their family caregivers. Many families struggle to provide proper care for their loved ones with Alzheimer's at home due to the high cost of external care options, and individuals with Alzheimer's often wander away from home and become lost, causing concern for their families. This tendency is likely to worsen over time. The goal of this research was to improve the user experience for Alzheimer patients using an application through effective user interface design, with a focus on elderly users. Design thinking was used as a method for creatively solving problems and developing a user interface for an application with functions for tracking and monitoring the movements of Alzheimer's patients. The usability of the application was tested through a scenario test and user feedback was used to evaluate the results. The user interface was improved in the second version based on user feedback from the first version. This study highlights the importance of considering usability in the design of applications for Alzheimer caregivers, as the primary users of this type of application are often elderly or have limited experience with information systems. To optimize efficiency of use, the design should be simple and minimize the number of elements on the screen to avoid confusion.
