This study aims to construct an empirical model of user engagement with smart wearables, focusing on wrist-worn wearable devices. Using survey data of current smartwatch and smart fitness tracker users (N = 457), four factors—physical interaction, interface assessment, cognitive absorption, and digital outreach—were examined as the main components of user engagement. Results showed that the four concepts reliably constituted the measurement model of user engagement. The proposed user engagement scale showed convergent validity with user attitudes toward wrist-worn wearables and usage intention. In addition, the four aspects of user engagement consisted of a process model, where physical interaction predicted interface assessment, interface assessment predicted cognitive absorption, and cognitive absorption predicted digital outreach.

这项研究旨在构建用户与智能可穿戴设备互动的经验模型，重点放在腕戴式可穿戴设备上。使用当前SmartWatch和Smart Fitness Tracker用户的调查数据（N（= 457），四个因素-身体互动，界面评估，认知吸收和数字外展-被视为用户参与的主要组成部分。结果表明，这四个概念可靠地构成了用户参与度的衡量模型。拟议的用户参与度表显示了用户对腕戴可穿戴设备的态度和使用意图的收敛性。此外，用户参与度的四个方面包括一个过程模型，其中物理交互预测界面评估，界面评估预测认知吸收，而认知吸收预测数字外展。
