Zebra Zebra：遠距操控吊車使用者介面 本研究主要為改善遠端操控吊車的一項困難點：使用者介面。在研究中我們開發了兩種 不同的使用者介面，第一種是有四個不同視角的系統，分別為上視、左側視、右側視與 全視；第二種也和第一種一樣有四個視角，另外再加上擴增實境來協助導引使用者。為 了測試使用者介面，我們使用機械手臂在實驗環境來模擬遠端操控的吊車，同時與一般 吊車的使用者介面做比較。使用者測試方面，我們主要分成兩個群組進行測試：職業吊 車操作員與一般學生。一般學生是沒有操作吊車經驗的族群，測試的結果藉由統計來說 明；職業吊車操作員是專業的群組，測試結果可以來評估使用者介面與使用者需求面。 與傳統使用者介面比較，我們發現藉由新的使用者介面，操作員可以較快完成吊裝工作 。綜合來說，本研究所開發的兩種使用者介面皆可以協助操作員操作遠端操控吊車，並 可以提高效率與降低心理壓力。

Zebra: user interface for tele-operated cranes

This research focuses on one of the major challenges in a tele-operated crane system, namely the user interface. In this research, we have designed two UIs specifically for a tele-operated crane system. The first UI is a four view system with a top view, left-side view, right-side view, and global view. The second UI has four views but uses additional guidance from AR technologies. To test the UIs, we used a robot arm to simulate a tele-operated crane in a testing environment. We also compared the UIs we designed against a conventional operation interface. We conducted a user test with two groups of participants: crane operators and students.

Students constitute a novice group, and their results are interpreted from a statistical perspective. Operators constitute an expert group, which provides evidences for evaluating if the developed UIs are realistic and fit the needs of the field. We found that use of the UIs we designed resulted in a shorter erection time than if the participants used the conventional operation interface. In summary, the two UIs developed in this research are able to assist operators in operating remote cranes more efficiently and with less mental load than by using the conventional operation interface.
