監測系統對樂齡族使用虛擬健身教練應用程式之影響

Abstract

在COVID-19影響之下，促進了人類居家運動，不少機構針對樂齡族開發虛擬健身教練，使他們減低孤獨感，為不同收入的樂齡族增加身體活動機會。目前虛擬健身教練逐漸具備監測系統，增加了樂齡族在應用程式上的互動體驗和提供安全考量。因此，本研究旨在以科技接受模式為理論，探討樂齡族對於使用虛擬健身教練的行為意圖，並以監測系統為調節變項，探討其調節效果，先以問卷調查392人，後以半結構性訪談12人，深入瞭解量化結果背景的意義，豐碩研究結果。主要研究結果：一、樂齡族最在意虛擬健身教練平台所提供運動知識及社交功能；二、知覺易用性和知覺有用性對行為意圖正向關聯不顯著，即使他們認為虛擬健身教練是有用及易用的，亦無法影響他們的意圖；三、當監測系統對樂齡族的知覺有用性和知覺易用性與態度之間具調節效果，證實監測系統成為評價虛擬健身教練的條件，而知覺有用性與態度調節效果較強。實務建議：一、應用程式應具資訊性，包括身體活動和飲食營養；二、增加人與人聯繫機會，如團體性運動、使用前的專人教學；三、強調監測系統有用性，增加目標設置提示功能。未來研究建議：一、增加虛擬健身教練的實際介入，驗證有使用監測系統之實驗組和沒有使用監測系統之對照組的兩者差異；二、探討不同社交存在、指導策略對意圖的差異；三、以目標設置理論和自我調節理論探討監測系統對使用者影響。Under the influence of COVID-19, exercise at home has been promoted. Many organizations have developed virtual fitness trainer for older adults. Virtual fitness trainer are now increasingly equipped with monitoring systems to enhance the interactive experience of the apps and provide safety considerations for older adults. Therefore, this study aims to investigate the behavioral intentions of older adults towards the use of virtual fitness trainer, using the technology acceptance model as a theory, and the monitoring system as a moderating variable to investigate its moderating effect. 392 people were surveyed by questionnaire and 12 were interviewed semi-structurally. The main findings of the study were: 1.The older adults cared most about the exercise knowledge and social features provided by the virtual fitness trainer platform; 2.The positive association between perceived ease of use and perceived usefulness on behavioral intention was not significant, even if they found the virtual fitness trainer useful and easy to use, it did not influence their intention; 3.The monitoring system moderated the relationship between perceived “usefulness and attitude”, and “perceived ease of use and attitude” of the older adults, it confirmed that the monitoring system became a condition for evaluating the virtual fitness trainer, and the moderating effect of perceived usefulness and attitude was stronger. Practical suggestions: 1.The apps should be informative; 2.Increase opportunities for human contact; 3.Emphasize the usefulness of the monitoring system and add a prompt function for goal setting. Suggestions for future research: 1.Increase the actual intervention of the virtual fitness instructor to verify the difference between the experimental group who used the monitoring system and the control group who did not use the monitoring system; 2.Explore the difference between different social presence and coaching strategies on intention; 3.Use goal-setting theory and self-regulation theory to explore the impact of the monitoring system on users.
