Scratch Head

A hand reaches up to the top of the head and the fingers scratch back and forth — puzzlement.

How (right hand; mirror to Left by negating the Z values)

• Reach up to the head: RightUpperArm:[20,0,80], RightForearm:[0,0,150].
• Lightly curl the fingers and scratch by flexing them back and forth (~[40,0,0] <-> [60,0,0]), looped. Add a small head tilt (Head:[0,0,10]).

Example

• "scratch your head" -> {"durationMs":1400,"say":"Hmm, let me think...","sequence":{"loop":2,"frames":[{"t":0,"pose":{"RightUpperArm":[20,0,80],"RightForearm":[0,0,150],"Head":[0,0,10],"RightIndex1":[40,0,0],"RightMiddle1":[40,0,0],"RightRing1":[40,0,0],"RightPinky1":[40,0,0]}},{"t":0.5,"pose":{"RightIndex1":[60,0,0],"RightMiddle1":[60,0,0],"RightRing1":[60,0,0],"RightPinky1":[60,0,0]}},{"t":1,"pose":{"RightIndex1":[40,0,0],"RightMiddle1":[40,0,0],"RightRing1":[40,0,0],"RightPinky1":[40,0,0]}}]}}
