Abstract

Data input supporting method and apparatus are disclosed. The data input supporting method includes receiving virtual data sent by an intelligent mobile device, analyzing the received virtual data according to a pre-stored key value mapping file, the key value mapping file saving a mapping relationship between the virtual data and a real instruction, encapsulating the real instruction obtained by analyzing the virtual data, and sending the encapsulated real instruction to a pre-established virtual device node, filling the real instruction into a corresponding system function by the virtual device node automatically according to an instruction type; and responding to a kernel space data injection event generated by filling the real instruction into the system function. Embodiments of the invention can support non-contact control of the intelligent mobile device to an electronic product through a wireless connection, thereby providing desirable user experience.
