Information input method and information input device

The invention provides an information input method and an information input device applied to mobile equipment provided with a dynamic double-eye camera. The information input method comprises the following steps: acquiring each frame image of an operated object in a sliding process by virtue of the double-eye camera by the mobile equipment; processing the acquired each frame image so as to acquire a position coordinate of the operated object, and acquiring a three-dimensional track corresponding to a three-dimensional coordinate of the operated object in the sliding process according to the position coordinate of the operated object and a double-eye distance measurement theory; mapping the three-dimensional track to a plane so as to acquire a two-dimensional track of the operated object; carrying out character recognition according to the two-dimensional track, matching corresponding characters in a configured database by virtue of a character recognition result, and displaying. According to the information input method and the information input device, the low-power-consumption information input can be realized in various screens.
