Wearable devices are products of advanced electronic technology, and their various accessories and sensors make them an ideal component for symbiotic systems that record and interpret users' cognitive and affective states and the respond accordingly. Wristband wearable devices are mainly used to track users' health and fitness conditions, such as sleep, calories burned, heart rate, and distance travelled in real time. Though user acceptance of information systems has been widely discussed and verified, unique features of wearable symbiotic devices merit further investigation, as in this study. These features include the redeployment of the human-computer interface from external devices onto the body itself, concerns about perceived comfort and privacy of the devices, and others. An Internet questionnaire survey was conducted based on the case of the Xiaomi Mi Band. Based on 548 valid responses, two models, representing users and nonusers, were established and analyzed by structural equation modeling (SEM) to evaluate the proposed research framework. Major research findings indicate: (1) attitude, social influences, and facilitating conditions are three essential antecedents to behavioral intention of the Mi Band; (2) for prospective Mi Band users, technology anxiety, novelty, and effort expectancy are important factors for favorable attitude; (3) for current Mi Band users, familiarity, effort expectancy, and perceived comfort affect their good attitude the most. Based on these findings, practical guidance for promoting wearable devices is suggested.

穿戴式裝置為一種全功能，自給自足式，且與身體結合的小型電腦系統，可讓使用者隨時隨地的存取個人健康資料。穿戴式設備的特質成為可記錄與詮釋個人認知與情感狀態，並適當回應的理想共生系統元件。儘管資訊系統接受行為已受到高度的探討與驗證，穿載式裝置的特殊性質，例如人機介面由外部裝置轉至身體，還有知覺舒適與隱私等相關問題，值得深入的探究。本研究小米手環為例，以網路問卷方式取得548 份有效樣本。針對回收資料區分為使用者(N=137)與非使用者(N=411)兩個模型，並以結構方程模型(SEM)進行分析。本研究主要結論為：(1)態度、主觀規範、與知覺行為控制為左右小米手環使用意圖的重要前因構念，(2)影響潛在使用者對小米手環有利態度的因素為科技焦慮、新奇性、與努力預期，(3)影響現有使用者對小米手環有利態度的主要因素為熟悉性、努力預期、與知覺舒適。研究結論有助提供實用的穿戴式裝置推廣策略與戰術。
