Stop / Halt Hand

A flat hand pushed forward with the palm facing out — the universal "stop".

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

• Reach the arm forward: RightUpperArm:[80,0,0], RightForearm:[0,0,0].
• Extend the wrist so the palm faces outward and the fingers point up: RightHand:[-45,0,0].
• Fingers extended and together (leave at rest-extended), thumb alongside.

Example

• "stop right there" -> {"durationMs":500,"say":"Stop!","pose":{"RightUpperArm":[80,0,0],"RightForearm":[0,0,0],"RightHand":[-45,0,0],"RightIndex1":[0,0,0],"RightMiddle1":[0,0,0],"RightRing1":[0,0,0],"RightPinky1":[0,0,0]}}
