I want to share my [Thoughts of Designing Leap Motion App Gestures] with you.. 🙂

• Stable
  Let the user act stably..
  Let the device detect it stably..
  Make the interaction stable..

• Intuitive
  Easier to remember as well…

• Don’t be too dumb.. Or make it funny
  Leap Motion is a cool thing…

• Won’t let the user get too tired easily
  Sometimes, How long the user wanted to use the app for – How long the user used the app for ≈ How Tiring it is
  Tiring may make it less interesting.. but not always a problem.. It depends on the what users mainly use the app for…
  I may use an app for a little while, but I’ll use it frequently… It should be funny/addictive/cool enough.. Maybe for fun..
  I may use an app for a longer while for work.. Shouldn’t be too tiring…

  Commands can be done with one hand should better be done with one hand, especially the frequent ones..

• Detecting Quickly
  It’s annoying if the user has to wait a little bit after a whole gesture is done every time then see the result..
  The movement patterns(Circle, Swipe, Key Tap, Screen Tap) recognized by Leap itself delay a little bit..
  We can make the movement patterns(not only official ones, like sign languages recognition) feel like real-time interacting by showing the movements in real-time like painting app..

• Easy to Learn
  It’s confusing if the user has to practice a gesture many times.. (Maybe it’s not stable…)

• Be clear with other gestures
  Not very good if you design these 3 gestures:
  1. Extending one finger only
  2. Extending two fingers
  3. Extending three fingers

  It may be tough(unstable) cause:

  • Sometimes Leap device detects one more/less finger than it is by mistake..
  • Switching from one-finger gesture to three-finger gesture may cause two-finger gesture
• Gestures can be something more
  Don’t limit it with only finger controlling…

Bad Experiences:
Stable / Intuitive / Detected Quickly / Easy to Learn / Clear with other gestures:

• “Did I do the gesture correctly?..” *waiting for the result*
• Sometimes it works, sometimes not…
• “Sometimes I was going to … but it’s detected as …”

Check this: Tone Mouse

Updates:

• New better intuitive gesture:
  
  
• The mouse cursor moves more stably while switching gestures…
• Several optional parameters:
  s[num] Move Scale..
  
Set Scale to 0.4:
D:\LeapMousion.exe s0.4

  c Click-Only…
  
Turn on Click-Only Mode:
D:\LeapMousion.exe c

  r Reversed….
  
Reverse Orientation:
D:\LeapMousion.exe r

  l Left Handed Mode…..
  
Turn on Left Handed Mode:
D:\LeapMousion.exe l
