dc.description.abstract | 360影片能夠紀錄全景的影像資訊,逐漸變的越來越普及。但是,當觀看者想要透過傳統的影片撥放器來快速的找到360影片中想看的事物時,觀看者必須要分別調控時間軸和旋轉觀看視窗,以防止在拉滑時間的過程中錯過一些重要的片段。觀看者必須在兩個不同的操作集中注意力並隨時切換滑鼠來調控,導致整個瀏覽 360 影片的過程變得非常困難和耗時。這篇論文提出了PanoSlot,一個專門設計給使用者在瀏覽360影片時能快速找到感興趣地方的介面。當使用者開始在時間軸上拉滑時,介面會顯示出格狀的圖片。橫向的圖片分別表示用不同角度的90度相機去拍攝360影片的內容,而縱向的圖片分別表示隨著時間變化上的連續縮圖。這個設計讓使用者可以僅透過一次的滑鼠點擊過程,在時間和空間的維度之間快速瀏覽360影片。使用者可以從時間軸往上移至格狀圖片中放開滑鼠即選取想看的影像,接著影片會從選取的時間和空間點開始繼續撥放。我們將設計出來的介面和YouTube的影片播放介面來進行比較。根據實驗結果顯示,PanoSlot是一個能讓使用者更快速的找到360影片中感興趣的地方,同時也可以減輕使用者在瀏覽360影片時的負擔和工作量的全新介面系統。 | zh_TW |
dc.description.abstract | The 360-degree video becomes increasingly popular as it contains a full field of environmental content. However, when searching the region-of-interests (ROIs) of a 360-degree video via conventional media players, users need to put attention on manipulating the camera view and the timeline slider, respectively, which increases the difficulty for 360-degree video browsing. We propose PanoSlot, a video scrubbing interface tailored for finding the ROIs in 360-degree videos. When the user scrubs the timeline slider, the interface displays a grid of thumbnails, where the row of thumbnails display the 360-degree keyframe from different camera directions, and the column of thumbnails stand for the timeline sequence of the corresponding camera view. This allows users to skim through both spatial- and temporal- domain of the 360-degree keyframe. By switching the cursor between the timeline slider and the thumbnail grids, our design allows users to manipulate the spatial and temporal-domains of a 360-degree video with a single mouse dragging. We compared the performances of PanoSlot and the existing video scrubbing mechanism utilized by YouTube. The result showed that PanoSlot enables users to reach the ROIs with less time-consumption and less workload. | en |
