Playing a violin need far more finesse than just dragging a bow across its string . There are pernicious shade in motion , pressure , and speed required that take twelvemonth to master . Or , you could wait forDylan Menziesto perfect his easy - to - play opticalO - Bowand just skip all the recitation and rehearsal .
Instead of strings , the instrument is essentially a smooth cop piston chamber with a dented groove that defend the obeisance as it ’s drop back across . At the bottom of that groove is an illuminated optic sensing element that tracks the bow ’s velocity , angle , and position , allowing different notes to be diddle , including the vibrato effect stringed instruments are get it on for .
On the backend there ’s of course custom software that manipulate the violin samples in genuine time to fit what ’s being play , but like with a MIDI keyboard the O - Bow could also be used as an user interface for a whole symphony orchestra of virtual musical instrument . And while it ’s just a inquiry project at the moment , Menzies does hope to one mean solar day commercialize the O - fore and presumably save young instrumentalist from hour of voluminous practice .
