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.
