隨著擴增實境技術的進步，我們預測未來各種行動裝置會與擴增實境技術會相互結合，並擴展到各種領域上。然而，擴增實境內的虛擬物件，實際上是浮現於空氣中，在操作時是觸碰不到的。如何在操作擴增實境物件時給予觸覺回饋，提供良好的觸覺感知效果以輔助操作，是未來觸覺回饋裝置發展的目標。本研究採用焦點團體法進行創新觸覺回饋裝置的構想收集，分析後進行模型製作，成功設計無須電力驅動的觸覺回饋裝置；除了經由輸入速率與錯誤率進行客觀評估，也使用了技術接受度模型進行主觀評估。儘管加戴觸覺回饋裝置進行擴增實境虛擬鍵盤的操作比空手操作好，但分析結果並沒有顯著差異，且在客觀數據上仍輸給現有的實體鍵盤。然而，從主觀分析上來看，使用者對於使用觸覺回饋裝置均有正向意願，因此此方面的研究在未來仍有很大的空間可以發展。本論文希望藉由創新觸覺回饋裝置的設計與驗證，提供該領域相關的資訊與數據，可供未來擴增實境觸覺回饋設計的研究能有所參考。

With the advancement of augmented reality (AR) technology, different kinds of mobile devices are being combined with AR and applied in various fields. However, users can not touch virtual objects in AR because they are only projections. As such, how to provide haptic feedback and haptic perception to assist user control when users manipulate AR-enabled devices is the goal in the future. This research employed a focus group to collect innovative ideas of haptic feedback devices. After analyzing the data and constructing a model, we successfully designed a haptic feedback device without electric drive. The model not only conducts objective assessments by Words per minute and the error rate, but also uses Technology Acceptance Model to perform subjective assessments. While the score of operating the AR virtual keyboard with haptic feedback device is better than without, it is still inferior to the control a physical keyboard offers. From the subjective assessment analysis, users had positive intentions of using haptic feedback devices, so we believe that research into such devices featuring AR still has much development space in the future. We hope our design and analysis can contribute to the literature by providing useful data and information for future research.
