Wearable Device Design and Usability Evaluation for Detecting Atrial Fibrillation of Elders

Abstract

Atrial fibrillation of elders has become a serious problem leading to death in the world which has raised the importance of heart rate monitoring However many of the studies focus on technical levels and clinical evidence only a few studies pay attention to integrating hardware and software and the usability of elders The objectives of this study are to design a new heart rhythm monitor necklace which is easier to wear and can effectively detect heart rhythm; use long-short term memory (LSTM) to distinguish atrial fibrillation; and conduct a usability experiment which measures time and error rate of operating our prototype The post study system usability questionnaire (PSSUQ) and a semi-structured interview are adopted to explore elders’ demands and difficulties This work not only designs a new style wearable device for elders but also explores their demands and difficulties Our design is expected to provide a better interaction between the user and the instrument and help elders live healthier
