DETERMINING FORWARD POINTING DIRECTION OF A HANDHELD DEVICE |
| 摘要 |
A forward pointing direction associated with a handheld device is estimated or determined by, for example, calculating a center of rotation of the device. A resultant combined or selected bias estimate may then be used to compensate the biased output of the sensor in, e.g., a 3D pointing device. |
