The user experience and usability of Wearable Health Devices (WHD-UXU) play a pivotal role in determining user acceptance. However, there is a scarcity of comprehensive research systematically addressing the current focus and future research directions of WHD-UXU using bibliometric analysis. Therefore, to unveil the latest research progress and the evolutionary trajectory of WHD-UXU research hotspots over the past decade, this study leverages 365 papers related to WHD-UXU gathered from the Web of Science (WOS) database. Employing bibliometric methods and integrating tools like VOSviewer and CiteSpace, a knowledge map is formulated, encompassing aspects such as keyword co-occurrence, references co-citation, and research collaboration networks. The research findings highlight that current WHD-UXU research hotspots predominantly revolve around (1) the study of usability in wearable health devices, (2) research on mobile health of wearable health devices, (3) the study of health monitoring in wearable health devices, (4) research on rehabilitation treatment of wearable health devices, and (5) the study of user acceptance in wearable health devices. Future research is anticipated to focus on areas such as human-computer interaction, affective computing, artificial intelligence, human-machine trust, user self-disclosure, privacy algorithms, and system design evaluation. Finally, the study addresses future research directions and challenges in this field.
