An input apparatus for controlling an information terminal includes a gesture detecting unit that detects a rotational movement of a wrist of a user about a lower arm of the user and an output unit that outputs a control command for controlling a device to be controlled to the device to be controlled on the basis of a rotational direction of the detected rotational movement. If the gesture detecting unit detects a first rotational movement in a first rotational direction and thereafter detects a second rotational movement in a second rotational direction that is opposite to the first rotational direction, the output unit outputs a second control command corresponding to the second rotational direction without outputting a first control command corresponding to the first rotational direction.
