隨著時代的發展，擴增實境相關技術近幾年來得到突飛猛進的進步，並且開始出現相關民用級別的硬體設備。目前擴增實境技術已經開始應用在各個領域舉凡教育、遊戲等，在這些領域中，快速有效且準確的接收界面訊息是最為重要的，這關乎使用設備效率以及使用者的體驗，但是與使用者反應速度最相關的界面訊息類型卻鮮少有相關研究，本研究將分析文字、圖像、動態圖像三種提示類型何者在使用時擁有最短的反應時間。

除了了解反應速度（提示開始顯示時間至使用者確認之時間差）與資訊的顯示類型之間的關係外，實驗也會分析使用者在操作過程中使用不同側的眼睛是否會影響其精神負荷，補充慣用眼相關研究的空白，並將結果作為擴增實境穿戴設備廠商開發硬體時的依據。研究選擇的精神負荷判斷參數為PERCLOS數值、注視時間、注視點數量、掃視時間、掃視點數量以及眼動面積。本次研究實驗分為前測實驗以及正式實驗兩個部分，兩次實驗中受試者均需進行動態視力檢測（主任務）以及提示在設備出現時點擊觸控板（次任務）兩個任務。

本研究通過前測實驗從選定的對比度以及位置參數組成的提示中挑選各個類別（文字、圖像以及動圖）中擁有最短反應速度的一個供正式實驗中使用，最終選擇為：文字（左上，低對比度）、圖像（左上，低對比度）以及動圖（低對比度）。正式實驗結果表示慣用眼在操作過程中並不會影響使用者的精神負荷，並且對接收提示的反應速度無影響。與此同時，結果也表明所使用的提示類型會影響使用者的PERCLOS數值以及反應速度。注視時間、注視點數量、掃視時間、掃視點數量以及眼動面積參數並未受到慣用眼以及提示類型影響。

本研究結果顯示提示類型的不同確實對使用者接收訊息的反應速度有所影響，慣用眼因素雖然並無發現對所選參數有所影響，但是該因素能夠作為未來相關軟體開發時的參考。未來研究方向為驗證更多類型的提示之影響以及了解慣用眼會產生影響的條件為何。

With the development of the times, augmented reality related technologies have made rapid pro-gress in recent years, and related civilian-level hardware devices have begun to appear. At present, augmented reality technology has been applied in various fields, such as education, gaming, etc. In these fields, it is most important to receive interface messages quickly and accurately. It is re-lated to the efficiency of the use of the equipment and the user experience. Still, it is only a few related research on the types of interface hints that are most relevant to the user's response speed. This study will analyze which of the three types of hints, text, image, and dynamic image, have the shortest reaction time when used.

In addition, the relationship between the reaction time (the time difference from the time when the hint is displayed to the user's confirmation), and the type of hints displayed were evalu-ated. The experiment would also analyze whether the use of eyes from different sides of the user during the operation would affect their mental workload to supply related research on dominant eyes and acted as the guide for the development of augmented reality wearable device hardware. The mental workload judgment parameters selected in this study were PERCLOS, fixation time, number of fixation, saccade time, number of the saccade, and eye movement area. This research experiment was divided into two parts: a pilot study and an official experiment. In both experi-ments, the subjects were required to perform a dynamic vision detection task (primary task) and click on the touchpad when the hint appears on the AR device (secondary task).

Through the pilot study, the one with the shortest reaction time in each category (text, image, and dynamic image) was selected from the hints of the selected contrast and position parameters for formal experiments. The final choice was: text (upper left, low contrast), image (upper left, low contrast), and dynamic image (low contrast). The official experimental results showed that the dominant eye did not affect the user's mental workload during the experiment and had no ef-fect on the reaction time to receiving hints. At the same time, the results also showed that the type of hints used affected the user's PERCLOS value and reaction time. Fixation duration, number of fixation, saccade time, number of the saccade, and eye movement area parameters were not af-fected by dominant eyes and types of hints.

The results of this study show that the different types of hints do affect the user's reaction time when receiving messages. Although the dominant eye factor did not affect the selected men-tal workload parameters, it can be used as a reference for future studies when developing related software. Further research directions are to verify the impact of more types of hints and to under-stand the conditions under which the dominant eye will affect.
