Notation plays a very important role in today's society. It acts as a communication medium between inventors and those who will implement their ideas. Without notation our knowledge of the past and present would be limited by our memory and prone to errors in oral transmission. Although we take for granted the existence of a suitable notation in almost all fields of human study, this is not true in the field of human movement. For example, in Western theatrical dance, no adequate means to record masterpieces existed until the twentieth century and thus most works from the past have been lost. In response to the literacy problem in dance, a number of systems have been developed in the past five centuries to record human movement, but most of these have failed to be practical under rigorous working conditions. Only a few have attracted substantial professional interest. The difficulty is that a dance notation must capture on paper a precise record, at each moment in time, of the position of each body part in three dimensions of space, as well as provide comprehensive information about movement dynamics and choreographic intention.
