Alzheimer's disease (AD) reduces independence and quality of life and increases the burden on caregivers. There are many challenges in daily life, including getting lost outdoors and forgetting to take medicine on time. These problems not only affect the quality of life of patients, but also bring additional burdens to caregivers. In response to these problems, more and more studies are trying to help patients better cope with the difficulties in life through smart devices. Bassam Al-Naami et al. found that smart wearable devices improve elderly patients' quality of life. Using Wi-Fi and Firebase, they enable real-time data sharing. Tested on 13 volunteers, the prototype showed high accuracy in vital sign monitoring and fall detection, aiding AD patient management. However, there is still room for improvement in the functions and user experience of existing devices, especially for the needs of elderly patients with Alzheimer's disease to store medicines when going out and take medicines in time. Through user testing and interviews, this study explored the preferences, needs and concerns of elderly patients with Alzheimer's disease for smart bracelet design. Participants valued key functions like medicine storage and reminders while also expecting comfort and clear medicine classification. This study proposes a smart bracelet for elderly Alzheimer's patients to store and remind them to take medicine outdoors. At set times, the built-in vibration alert activates, and the medicine box pops open, pushing the pill to the port for easy access. This design ensures timely medication intake with convenient carrying, storage, and touch. The user test recruited 10 Alzheimer's patients to participate in the experience. The user experience of the bracelet was evaluated by using the System Usability Scale and user interviews. Most users accepted the bracelet, and future research will assess its long-term impact on patients' quality of life.
