Information terminal, control system, and control method

A control system comprising:

• an information terminal that is carried by a user of a moving object, that includes a display configured to detect a touch on a display image, and that performs movement control of the moving object based on a specific operation including a series of touch operations of the user on the display;
• and
• a control device configured to cause the moving object to move according to the movement control,
• wherein after the information terminal causes the display to display a first guidance image that extends in a left-right direction, the information terminal determines whether a first position on the first guidance image where the user has touched is closer to a right side or a left side, and causes the display to display, at the first position, a second guidance image that has a length in a left-right direction shorter than that of the first guidance image and that serves as a starting point of the specific operation, and
• wherein the second guidance image is initially displayed only after the determination of whether a first position on the first guidance image where the user has touched is closer to the right side or the left side.
