Computer science development of sophisticated computing equipment. Wilhelm Schickard designed and constructed the first working mechanical calculator in 1623. In 1673, Gottfried Leibniz demonstrated a digital mechanical calculator, called the Stepped Reckoner. He may be considered the first computer scientist and information theorist, for, among other reasons, documenting the binary number system. In 1820, Thomas de Colmar launched the mechanical calculator industry when he released his simplified arithmometer, which was the first calculating machine strong enough and reliable enough to be used daily in an office environment. Charles Babbage started the design of the first "automatic mechanical calculator", his Difference Engine, in
Digital puppetry suit with potentiometers and created the first working motion capture rig, animating 3D figures in real-time on his CRT screen. He made several short films with this system, which he called ANIMAC. Among the earliest examples of digital puppets produced with the system included a character called "Mr. Computer Image" who was controlled by a combination of the ANIMAC's body control rig and an early form of voice-controlled automatic lip sync. Perhaps the first truly commercially successful example of a digitally animated figure being performed and rendered in real-time is Waldo C. Graphic, a character created in 1988 by Jim
