摘要

在CAD (computer-aided design)軟體中操控3D空間中的虛擬物體在空間互動領域中相當重要。其中最快的即為等度(isotonic)的裝置。但現有研究的原形多沒有經過審慎的使用者評估。而且不同程度的虛實物體對應與物體的方向性資訊重要與否，至今仍未有定論。在空中及放置的裝置也並沒有過全面的比較。故我們發明了兩種裝置，並且探索這些問題的答案。我們進行了一個完整的使用者測試，比較現行代表性的等度裝置與我們的裝置，並分析得到的質化與量化數據，提供一系列設計原則供未來的研究做參考。我們發現，在操作CAD旋轉時，裝置是否為類圓形比裝置的映對程度更重要(79%的使用者選擇使用)，52%的使用者覺得了解方向很重要，而空中的裝置也比放置的裝置更好，無論是在使用者喜好(64%)與主觀速度(75%)。

To manipulate a 3D object in CAD was always an important issue in spatial interaction. However, the existing prototype for this purpose was not properly explored in respect of user behavior. Also, whether the orientation and the degrees of mapping were important was still an open question. And we didn't know whether in-air or on-the-ground manipulator was better. Therefore, we made two innovative manipulators to explore the question. We conducted a complete empirical study comparing current representative rotation devices with our own devices. Both quantitative and qualitative results were analyzed to provide a series of design principles for the future development in this field. We found that when manipulate the rotation in CAD software, the spherical attribute was more important than the shape mapping or orientation information (79% users preferred to use them). Also, 52% users found it helpful to know orientation. Moreover, in-air manipulator was better than on-the-ground one, both in user preference (64%) and subjective speed(75%.)
