New technology makes gestures in music


22/02/2012

Some people talk with their hands, using sign language. A researcher from the University of British Columbia decided to prove that, thanks to modern technology and capabilities of computer design and simulation of "talking hands" can be in the literal sense of the expression.

Sidney Fels (Sidney Fels) and his research team equipped with a pair of regular gloves position-sensitive sensors that detect motion and issued certain sounds when they were in three dimensions. Different hand gestures made possible types of sounds. For example, the right hand is clenched contributed reproduction of consonants, and open hand gave out the vowels. Meanwhile, the left-hand control is performed such short sounds, such as consonants B or P (in American English).

The idea, in part, was to duplicate some of the throat and tongue movements in the pronunciation of certain sounds during a call. The vowels are open sounds, which are formed in the open throat and mouth, so open hands made the same types of sounds.

For an additional level of control, the right hand reproduces the high pitched sounds, while in the raised position and lowered the tone, getting a horizontal position. Such technology can also be used to create music. Among his colleagues, Fels, who took part in the development of a new project were Professor of School of Music of the University of British Columbia, Robert Pritchard (Robert Pritchard) and Jonty Wong (Johnty Wang), a specialist in computer design and a concert pianist. Already there have been several concerts in which the invention Fels has been used as a musical instrument.

While this technology has become the embodiment of the idea of creating a virtual musical instrument, but Professor Fels is convinced that his invention may find application in industrial sectors such as engineering, especially in the movement of heavy equipment. Thus, the cranes that lift and move objects of varying severity can be controlled with gestures.
