<P>PROBLEM TO BE SOLVED: To enable an electronic musical device which performs various musical controls for surely performing desired musical control and further, perform various musical controls by variously changing the state of motion of the object in an operation space. <P>SOLUTION: The electronic musical device which instructs musical controls, corresponding to the state of motion of the object moving the predetermined operation space, is equipped with an optical means which has at least one light source which irradiates light into the operation space and at least one light sensor which receives light which has been reflected by an object in the operation space so that it has at least two light paths which reach from the light source to the light sensor via the object, with the detection values being output, according to the quantity of light received via the respective light path; a signal generating means of generating music; and a musical controller which controls the musical generated by the signal generating means, when the correlation between the current values of the detection values of the various paths satisfies specified relations. <P>COPYRIGHT: (C)2008,JPO&INPIT |
