First Claim
Patent Images
1. A computer-implemented method performed by one or more processors for tracking movement of a motion-based electronic input device, the method comprising the steps of:
- receiving one or more measured acceleration values indicative of the acceleration of an input device moving in a tilted plane of motion that is tilted with respect to a horizontal plane;
determining one or more corrected motion values by accounting for the effects of gravity on the measured acceleration values due to the tilted plane of motion;
calculating a change in position of the input device based on at least one of the one or more corrected motion values;
calculating a net tilted gravitational error in the tilted plane of motion;
comparing the calculated net tilted gravitational error gr′
with a static gravitational force g; and
determining whether the change in position calculated is within a range based on the comparison of gr′
with g.
