An information processing method, a system and an electronic device are disclosed. The method includes: acquiring a first motion locus with the first electronic component, where the first motion locus is generated by the first part from a first time instant to a second time instant; and acquiring a second motion locus with the second electronic component, where the second motion locus is generated by the second part from the first time instant to the second time instant. The first electronic device may obtain and execute a first control instruction corresponding to the first motion locus and the second motion locus. With the method and electronic device, an advantage of precisely recognizing a slight local action of the user is achieved.
