Abstract
Embodiments of the invention relate to determining the position of a hand-held object from the acceleration of the hand-held object. In an embodiment, a measure of the displacement of the hand-held object is derived in part from a measure of an acceleration of the hand-held object. A measure of a position of the hand-held object is generated based on the displacement of the hand-held object, and is output.
Claims31
A method for determining the position of a hand-held object from the acceleration of said hand-held object, said method comprising:
- generating a measure of the displacement of said hand-held object, wherein said measure of said displacement of said hand-held object is derived in part from a measure of an acceleration of said hand-held object;
- generating a measure of a position of said hand-held object, wherein said generating said measure of said position of said hand-held object is based in part on said displacement of said hand-held object;
- and
- outputting a measure of said position of said hand-held object, wherein said measure of said position is supplied to a hand-held object responsive application program.
A system for determining the position of a hand-held object, comprising:
- a displacement measure generator for generating a measure of the displacement of said hand-held object, wherein said measure of said displacement of said hand-held object is derived in part from a measure of an acceleration of said object;
- a position measure generator for generating a measure of the position of said hand-held object, wherein said measure of a position of said hand-held object is based in part on said displacement of said hand-held object;
- and
- a position measure output for outputting a measures of said position of said hand-held object wherein said measure of said position of said hand-held object is supplied to a hand-held object responsive application.
A method for determining the position of an hand-held object from an acceleration of said hand-held object, said method comprising:
- producing a measure of said acceleration of said hand-held object;
- integrating said measure of said acceleration of said object to produce a measure of a velocity of said hand-held object;
- and
- integrating said measure of said velocity of said object to obtain a measure of said displacement of said hand-held object. producing a measure of a position of said hand-held object, wherein said generating a measure of said position of said hand-held object is based on said displacement of said hand-held object;
- and
- outputting a measure of said position of said hand-held object.
