摘要

In this study, two issues were investigated: 3D game interface and 3D visual
experiences. For the first issue, eight users participated in testing the user experience of
“Avatar-the Game”. This evaluation was focused on setting 3D mode and in-game
interface, which contained usability testing and subjective satisfaction. Moreover, we
used the results of testing and heuristic evaluation for improving the main menu and
in-game interface design. In addition, we found some issues of 3D content design such
as focal distance and perceived depth.
Accordingly, previous issue extended from the evaluation and improved design of
Avatar-the Game provided some view points on visual experiences. Therefore, we
focused on 3D visual experience and perceived depth. Sixteen participants were
recruited in the experiment examining the effects of convergence distances and
ambient illumination on visual fatigue, visual comfort, and perceived depth.
The results indicated a significant interaction effect between ambient illumination
and convergence distance on visual fatigue and significant simple main effects of
ambient illumination and convergence distance. Moreover, the results of visual comfort
showed a significant main effect of ambient illumination on comfort of depth and
coordination. Convergence distances were divided into two groups, convex and
concave, based on the impression of 3D presence. We found that convergence distance
would affect perceived depth in convex and concave group. The results of regression
showed that convergence distance predicted perceived depth divided into two fitted
lines: convex and concave.

本文探討兩個議題：3D 遊戲介面和3D 視覺經驗。在第一部分，八位使用者
參與Avatar-the Game的使用者經驗測試。本評估聚焦於設定3D模式以及遊戲中
介面，其中包含使用性測試與主觀滿意度評分。進一步根據測試結果以及捷思性
評估〈heuristic evaluation〉進行主要畫面及遊戲中的介面改善設計。此外，在評估與改善設計的過程中發現一些關於3D 內容設計的議題，如焦點距離及感知深度〈perceived depth〉。
第二部分，透過Avatar-the Game 的評估與改善設計延伸的感知深度
〈perceived depth〉相關議題提供一些視覺經驗探究的觀點。因此該實驗聚焦於視覺經驗及感知深度。十六位受試者參與本實驗，本實驗旨在檢視聚合距離
〈convergence distance〉與環境照度對視覺疲勞、視覺舒適度以及感知深度的影響。
實驗結果顯示環境照度與聚合距離在視覺疲勞上有顯著交互作用，兩因子也有顯著的主要效果。而視覺舒適度中僅深度舒適與協調舒適在不同環境照度下有顯著差異。此外，由於不同聚合距離形成不同性質的立體效果，因此將其劃分為兩個組別：凸組、凹組。當中發現在不同感知深度顯著的受聚合距離所影響，且根據不同組別進行迴歸，結果顯示聚合距離能顯著預測感知深度並就凹凸組各有其配適之迴歸式。
