The invention discloses a user identification method and device. According to the method and the device, a plurality of pressure sensing points for collecting pressure signals are arranged on the surface of a remote controller; the controller combines multiple pressure signals into a pressure vector and sends to a terminal; the terminal receives the pressure vector and reads a preset user identification model; pressure vector mass centers corresponding to each user are recorded in the user identification module; the pressure vector mass centers are the mass centers of hyper-spheres constructed in a vector space by history pressure vectors corresponding to the users; the distances between the received pressure vector and the pressure vector mass centers are calculated; the user corresponding to the pressure vector mass center with the minimum distance is selected as the holding user of the remote controller. According to the scheme provided by the invention, the user currently holding the remote controller can be identified.
