"An*thro*po*cy*ber*syn*chro*ni+*ci*ty n (fr Gk anthropos, man +cyber, governor + synchronicity, coming together in time) The study of the rhythmic aspects of the person-computer interface".
Autodesk Distinguished Fellow Joel N. Orr coined the term to describe "an area of person/machine interface research that is largely unexplored-- but holds great promise, especially for virtual reality. Untapped aspects of our being can greatly enhance the contact between people and computers. The secret: Rhythm. Human-scale rhythms--visual, auditory, and kinesthetic--can and should be incorporated into the design of effective computer systems".
