Motion capture is the process of recording the movement of objects or people.
Rotoscoping - animation technique where animators trace over footage, frame by frame for use in live action and animated films
First movie to use Motion Capture: Snow White and the Seven Dwarfs (1937). Live models were used to guide the drawings.
Highlander: The Last of the MacLeods (1995). Employed Motion Analysis
Keyframing - animation made up of key frames (drawings) that define the starting and ending points of any smooth transition.
District 9 (2009)
Rise of the Planet of the Apes (2011)
John Carter (2012)
The term ‘performance capture’ is used to describe advanced motion capture
In addition to body movements, more minute details such as emotion, finger movement, and facial detection can be captured and used.
Since the movie Avatar, one of the earliest, most famous, examples of performance capture, it has also been used in games such as L.A. Noire and Heavy Rain
100+ markers on an actor’s face to capture facial expressions.
Very cumbersome for the actor - takes a long time to put all dots on, and the
actor cannot touch their face
until they are removed

Mixamo recently released Face Plus for Unity - capture face data with only a webcam.
Sega’s Heavyweight Champ
(1976) for arcades
Two boxing glove controllers you punch,
one for each player. A 1987 remake
gave one player control of two punch
controllers. The cabinet can also turn
from side to side, and the boxer moves
The ‘world’s first full-body
experience video game’.
Three arcade cabinet designs. The one pictured enables turning by leaning on the motorcycle.
1989 for NES
Move the glove controller around. The time taken for ultrasonic sound to travel between speakers on the glove and microphones on a receiver unit is used to triangulate position.
Optical fibers can detect bending of the glove (light is obstructed when bent).
Considered difficult to use
Octogonal device on the floor that had eight infrared light sensors beamed upwards for detecting movement. Like the Power Glove, also not well-received.
Most game modes/variants feature pressure sensors in four directions.
These sensors must be stepped on to match the arrows appearing on screen in time with music.
First major ‘exergaming’ (exercise gaming) series.
Shooting game where players
duck for cover and dodge… by
actually ducking for cover and
Uses infrared sensors.
Prince of Persia (1989)
Rotoscoping - videos (like the one below) were used as reference.
(for animated GIF)
Used from the second entry in the
series (2001) onwards.
The upcoming Metal Gear Solid 5 uses facial capture. Actors had their face and expressions captured from many angles.
The actors (and stunt doubles) from the original movies were the motion capture actors for the game. Motion capture took 3 months.
Used MotionScan for performance capture, with 32 cameras for facial animation.
The blooper reel above shows the tech better than the game does because it features actors breaking character and being more natural.
