Instead of calculating a velocity value of the casing by simply integrating the detected acceleration value, the velocity value of the casing in the first direction is calculated based on the acceleration value and the angular velocity value that have been detected. As a result, a highly-accurate calculation of the velocity value of the casing becomes possible, and a movement of a pointer on a screen becomes a natural movement that matches a sense of a user based on a displacement corresponding to the velocity value. | 2010-04-29 |
20100103096 | INPUT APPARATUS, CONTROL APPARATUS, CONTROL SYSTEM, CONTROL METHOD, AND HANDHELD APPARATUS - An input apparatus, a control apparatus, a control system, and a control method therefor, that are capable of solving a problem on gravity that affects an acceleration sensor of an input apparatus when tilted from its original position, and reducing a calculation amount are provided. An MPU of an input apparatus corrects angular velocity values by rotational coordinate conversion corresponding to a calculated roll angle to obtain correction angular velocity values (second and first correction angular velocity values) as correction values. Accordingly, even when a user moves the input apparatus in a state where the input apparatus is tilted with respect to an axis in a gravity direction (vertical axis) about a Z axis, effects of gravity acceleration components in X′- and Y′-axis directions that are generated by the tilt can be removed. | 2010-04-29 |
