  • Patent number: 8502774
    Abstract: To provide an input apparatus, a control apparatus, a control system, and a control method that are capable of restricting a movement of a pointer on a screen by a user operation even while the input apparatus is moving. In a state where a movement button is not pressed by a user, an MPU of an input apparatus is not outputting a movement command or is outputting a movement command with a displacement amount set to 0. In other words, even when the user holds the input apparatus and moves it, a pointer does not move on a screen. As a result, a movement of the pointer unintended by the user can be restricted. When the movement button is pressed, that is, when a first operation signal is input via a first switch, the MPU starts outputting the movement command. By receiving the movement command, an MPU of a control apparatus controls display of the pointer so as to start the movement of the pointer that corresponds to the movement command.

  • Patent number: 8456422
    Abstract: An input apparatus, a control apparatus, a control system, a control method, and a handheld apparatus with which a user can easily control a movement and stop of a pointer displayed on a screen are provided. An input apparatus includes a sensor unit for detecting a movement of a casing and a button. An MPU outputs a determination code when a press of the button is released within a first time period. On the other hand, when the button is pressed and held for a time period equal to or longer than a first time period, a movement command is output from after an elapse of the first time period. Accordingly, the button is provided with a function corresponding to a determination input button and a function corresponding to an input button for controlling a movement and stop of a pointer, for example. As a result, a user can easily control the movement and stop of the pointer without mixing up an input operation for moving and stopping the pointer with other input operations.

  • Patent number: 8416186
    Abstract: 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.
