User-Defined Gesture ! 
for! 
Flying Object 
Wei-Hsuan Huang ! 
! 
!
Motivation 
• UAV is becoming more prevalent 
• Interaction is always for mobile but gesture 
• Not surface gesture, it’s in-air
Target 
• Our results will help designers create better 
gesture sets informed by user behavior. 
• Better gesture means the learning curve of gesture 
will obviously lower than mobile’s or other 
controllers’ 
• Users prefer gesture to using controller
Related Work 
• User-Defined Gestures for Surface Computing 
• Taxonomy of Gesture in Human Computer 
Interaction 
• Exploring 3D Gesture Metaphors for Interaction 
with Unmanned Aerial Vehicles
User Study 
• User Study 1 (User-Defined) 
• User Study 2 (User-Selected)

• Combination
Displacement 
• 起飛&降落 
• 上&下&左&右&前&後 
• 左旋轉&右旋轉 
• 定點到定點
Application 
• 對⾃自⼰己照相 
• 對⾃自⼰己錄影 
• 對⾃自⼰己連拍 
• 選取&跟隨
Combination 
• 調整移動速度 
• 邊移動邊旋轉 
• 跟隨他⼈人拍照錄影

• 10 males, 6 females 
• Age range from 19 to 25 
• Interesting findings 
• absolute position 
• people prefer gesture to 
mobile control
Next Step 
User Study 2
Introducing User Study 2 
• Watch video of Gesture set 
• Let users select their preferred gestures 
• Let users experience gesture & mobile control 
• Use Kinect v2 to implement system 
• Calculate completion time and learning curve
Q&A
可能碰到的Q&A 
• 為什麼要⽤用Kinect? 
• 因為使⽤用Kinect最無拘無束,不需要額外加裝sensor,若是⼿手上裝了東⻄西便會感到不是那麼舒適,若使⽤用 
Leap Motion範圍⼜又太⼩小,反⽽而會影響使⽤用者⾃自定義的⼿手勢 
• 為什麼要有拍照的功能? 
• 因為現在⼤大部分的飛⾏行器都會搭配Camera,常⽤用的功能也都是攝影,⽽而這篇重點是如何跟Flying Object 
互動,⽽而不是Flying Object可以做什麼,關於這個問題,未來可以⽤用另⼀一個題⺫⽬目來⼀一併討論打燈光,放⾳音 
樂甚⾄至其他更潮的功能 
• 為什麼要有定點到定點這個⼿手勢? 
• 我們認為這是未來⼀一定會使⽤用到的功能,⼈人們⼀一定會希望直接指定某個絕對位置讓飛⾏行器移過去,⽽而不是⾃自 
⼰己慢慢的微調到某個位置,也因為之前沒有⼈人探討過3D空間⽤用⼿手勢指定絕對位置過
可能碰到的Q&A 
• 為什麼會有選取? 
• 我們認為上述功能預設都屬於對控制者本⾝身,但如果應⽤用上需要對其他物體做應⽤用的話,會需要這種功能, 
故放進Task看受試者的反應 
• 為什麼要討論in-air的⼿手勢? 
• 因為我們認為in-air的⼿手勢是always available的,我們很容易可以伸出⼿手來操作,無需其他物件 
• 為什麼要分Study1 & 2? 
• 就像Steve Jobs講的,使⽤用者⾃自⼰己常常不知道什麼是最好的,直到你拿給他們看,所以我們讓Study1的使⽤用 
者發想,Study2的使⽤用者選擇,兩群使⽤用者不重複
