1. A hand held electronic device, comprising:

  • a gyroscope that generates gyroscope data representing a trajectory of a movement of the handheld device;

    an accelerometer that generates accelerometer data representing a tilt of the handheld device relative to earth'"'"'s gravity, wherein the trajectory comprises at least one segment; and

    a processing component that generates a command to initiate a function that corresponds to the command in the hand held electronic device;

    wherein generating a command comprises;

    moving the handheld device along a selected trajectory corresponding to the command;

    determining the selected trajectory and segments thereof using at least one of the gyroscope and the accelerometer;

    processing data from the at least one of the gyroscope and the accelerometer to derive data parameters;

    wherein the data parameters include any of at least one of an angle of the trajectory, an inverse tangent of a change in pitch divided by a change in yaw, a location of a crossing point or a number of times in which the trajectory changes in direction; and

    determining the command from the determined selected trajectory and segments thereof based on the derived data parameters to initiate the function in the handheld device.
