Pidepal model
The main question here is: when the "stickman"[1] reduction appears and why is it mainstream.
The figure is already present in the MIT — Graphical Marionette in 1982.

Biomechanics lab, Utah State University, USA
The biomechanics laboratory at USU can be rooted back to the mid 1980’s when Steve Dunn began using a dedicated space in the HPER building to teach basic hands-on concepts related to biomechanics.

Animation database - An animation database is a database which stores fragments of animations or human movements and which can be accessed, analyzed and queried to develop and assemble new animations.
Gesture recognition - Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion or state but commonly originate from the face or hand.
Finger tracking - In the field of technology and image processing, finger tracking is a high-resolution technique that is employed to know the consecutive position of the fingers of the user and hence represent objects in 3D.
Inverse kinematics - (a different way of making CGI effects realistic).
Kinect (created by Microsoft Corporation).
Motion capture acting - Motion-capture acting, also called performance-capture acting, sometimes abbreviated as MoCap or Pcap, is a type of acting in which an actor wears markers or sensors on a skintight bodysuit or directly on the skin.
