A method and system for operating a mobile device includes interpreting a user-defined pattern detected by at least one of a touch interface and a motion sensor included with the mobile device. The user-defined pattern may be interpreted as at least one of: a polygon, an ellipse, a curve, a line segment, an alphanumeric character, and a movement of the mobile device. The user-defined pattern may be a two-dimensional pattern traced by the user on the touch interface. When the user-defined pattern is recognized, a wireless communication command may be executed by the mobile device. The wireless communication command may be a telephone command or a remote control command for a remote-controlled device.
