Summary: | 近年來多軸空拍機快速發展與普及,可預見其未來將成為新一代的輔助攝影工具。空拍機打破距離、角度的限制,讓時下流行的自拍(Selfie)照片相較於以往以手臂或自拍棒輔助的方式,拍出更具特色及多樣性的構圖。然而當前空拍機操作方式複雜,使用者需花費一定的練習時間才能熟練地控制空拍機至預定位置進行拍攝。
本研究針對空拍機的使用情境進行觀察,歸納傳統操作方式造成的問題,再依不同互動控制方法討論過往研究提出的解決方法之優勢與限制,並依據自拍行為之心智模型及過往研究經驗,設計兩階段互動流程:相機定位階段(Positioning)及鏡頭構圖階段(Framing),並在各階段中分別提出直接指向(Direct Pointing)、移動微調(Fine Tuning)及構圖調整(Framing)三種有別於傳統類比搖桿操控之互動模式。
本研究另設計一俱觸覺控制回饋、可單手操作之實體自拍遙控器,搭配前述互動設計實作兼具自動化移動及以使用者為中心進行操作之空拍機自拍互動控制系統原型Skyfie,並於戶外環境設計實驗場域進行使用者測試,測試使用者指揮空拍機至指定位置拍照之操作,評估互動流程中各操作方法之優劣。測試結果顯示Skyfie 互動控制系統相較於傳統的類比搖桿操控方式更易於學習及使用,且符合使用者對空間的認知,並依照回饋意見進行互動模式修正,以達成對空拍機初學者而言也簡單易學的互動操作方式。 === As personal drones become more popular, we can envision a future where flying selfie bots are always with us. Drones break the limits of distance and angle, providing more diversified composition than taking selfie with arms or a selfie stick. However, users have to be very skillful to pilot the drone and are not easy to take aerial selfies by state-of-the-art methods.
Based on user observation and the mindset of selfie taking, we summarize the problems caused by the traditional control methods and generalize the interaction flow of selfie taking into two stages: Positioning and Framing stage. In each stage, we present new interaction techniques including a direct pointing technique, fine-tuning technique, and a touch manipulation for framing.
We also present a selfie remote controller designed for single-hand operation to collocates with the interaction techniques, and implement a proof-of-concept Skyfie system for an outdoor user testing. The result shows users felt intuitive and expressed enthusiasm to take aerial selfies with our techniques. Finally, we discuss the insights from the evaluation and conclude with future directions.
