1. An input device, comprising:

  • a multi-touch sensor that at least partially encloses a body of the input device and that senses one or more contacts with the body;

    an inertia measurement unit that is attached to the body and that at least measures a tilt angle of the body with respect to a horizontal surface and a roll angle of the body along a length-wise axis of the body with respect to an initial point on the body;

    determining a difference angle between the roll angle of the body and a standardized roll angle of a plurality of grip templates, each grip template having a corresponding grip pattern that represents a corresponding grip on the input device and a corresponding tilt angle of the input device; and

    comparing the tilt angle and the difference angle to each of the plurality of grip templates to determine a grip pattern that corresponds to a predefined function.
