The terms dance technology and Dance and Technology refer to application of modern information technology in activities related to dance: in dance education,  choreography,  performance, and research. 
In education, dance technology includes various advanced media, such as video, interactive computer programs and internet.,  as well as training in the use of modern technologies for dance creation.  
One of the earliest uses of computers for dance were carried out in the 1960s at the University of Pittsburgh, where the choreographic process was codified and manipulated by computer, although the results were not published. 
In the 1970s there were several attempts to computerize the Labanotation and later the Benesh notation. These attempts naturally evolved into attempts to translate the symbolic notations into computer models of the moving human body and further to computer-assisted creation of choreographies. 
Dance technology allows for innovative art forms, such as collaborative network performances  and The Dance Technology Project, Atlanta Ballet and Georgia Institute of Technology, with its first performance, "Non Sequitur,? of a ballerina dancing with a computer animated "virtual" dancer was shown on CNN's Future Watch program, May 1994. 
Virtual dance allows the exploration of physical and virtual dance and blended realities. The first ballet company to perform in a virtual environment was Ballet Pixelle. Inarra Saarinen is the artistic director and choreographer who creates animations, imports them into the virtual reality environment Second Life, and then choreographs using the animations. The avatar dancers are from all over the globe and are not automated in any way but truly dance with each other and the music. Her company began in 2006 and is still performing. Other companies, ZeroG Skydancers, director DC Spensley (Dancoyote Antonelli), also established in 2006 and also still performing.
Integration of live dance performance with dance environment (sound, lighting) was pioneered by Mark Coniglio, whose 1989 MidiDancer measured the angular change at several joints on the dancer's body and used the measurements to control music.
