1. A method for interpreting orientation invariant motion using a computing unit, the method comprising:

  • receiving one or more sets of reference readings;

    receiving sets of readings over a time period from a set of inertial sensors housed in a handheld device gripped by a user in one of many orientations as the handheld device is being moved from one location to another location in a 3-dimensional space;

    computing a set of rotations of the handheld device from the sets of readings;

    computing a representation of a movement of the handheld device from the sets of readings, the set of rotations, and the one or more sets of reference readings, wherein the computing of the representation of the movement includes at least one of;

    rotating at least some of the sets of readings, rotating at least some of the reference readings, partially rotating at least some of the sets of readings and partially rotating at least some of the reference readings to readings that are substantially independent of how the handheld device is gripped; and

    wherein the reference readings include first and second sets of data, the first set of data is determined from a vector field and pertains to an initial orientation of the handheld device gripped in accordance with a reference grip, and the second set of data is determined from the vector field as the handheld device is gripped by a different user with a different grip, and the representation of the movement is substantially independent of how the handheld device is gripped and the reference readings are taken when the handheld device is detected to have a sudden move.
