To provide an input apparatus, a control apparatus, a control system, a control method, and a handheld apparatus with which a movement of a pointer on a screen can be stopped, for example, with a simple operation or without a user being aware of the operation. An MPU judges whether absolute values of acceleration values are both equal to or smaller than a threshold value (hereinafter, referred to as threshold value for convenience). When both of the absolute values for the acceleration values are not equal to or smaller than the threshold value, the MPU transmits velocity values to a control apparatus. Otherwise, the MPU stops outputting (transmitting) the velocity values. Typically, a time when a position of a casing of an input apparatus falls within an angle range an angle ±alpha from a line that is perpendicular to a ground (horizontal plane) is a time when the absolute values become equal to or smaller than the threshold value.
