Information terminal, control system, and control method
An information terminal carried by a user of a moving object includes: a display configured to perform a position instruction operation on a display image; and a controller configured to perform movement control of the moving object based on a specific operation including a rotation instruction operation of the user on the display. After the controller causes the display to display a first guidance image that extends in a left-right direction, the controller causes the display to display, at a first position instructed by the user on the first guidance image, 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.
1 . An information terminal carried by a user of a moving object, the information terminal comprising:
a display configured to detect a touch on a display image; and
a controller configured to perform movement control of the moving object based on a specific operation including a series of touch operations of the user on the display,
wherein after the controller causes the display to display a first guidance image that extends in a left-right direction, the controller 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.
2 . The information terminal according to claim 1 ,
wherein the controller sets a second position on a side facing the first position in the left-right direction, and causes the display to display, together with the second guidance image, a third guidance image that prompts a continuous touch operation in an oblique first direction including a direction directed from the first position to the second position.
3 . The information terminal according to claim 2 ,
wherein when the continuous touch operation in the first direction is performed, the controller causes the display to display a fourth guidance image that prompts a continuous touch operation in a second direction different from the first direction.
4 . The information terminal according to claim 3 ,
wherein the controller causes the fourth guidance image to be displayed before an instructed position based on the continuous touch operation in the first direction reaches an end portion of the display.
5 . The information terminal according to claim 3 ,
wherein when a movement distance of an instructed position based on the continuous touch operation in the first direction exceeds a predetermined distance, the controller causes the fourth guidance image to be displayed.
6 . The information terminal according to claim 3 ,
wherein the specific operation includes a rotation instruction operation of the user on the display, and
wherein when the continuous touch operation in the second direction is performed, the controller causes the display to display a fifth guidance image that prompts the rotation instruction operation in a predetermined rotation direction corresponding to the first position.
7 . The information terminal according to claim 6 ,
wherein when the rotation instruction operation is started, the controller causes the display to hide the fifth guidance image, and causes the display to display an icon indicating an instructed position based on the rotation instruction operation.
8 . The information terminal according to claim 1 ,
wherein the controller causes the display to display an execution state image indicating an execution state of the movement control, and causes the display to display the first guidance image below the execution state image.
9 . 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.
10 . A control method by an information terminal that is carried by a user of a moving object, and that includes a display configured to detect a touch on a display image, and a controller configured to perform movement control of the moving object based on a specific operation including a series of touch operations of the user on the display, the control method comprising:
causing, by the controller, the display to display a first guidance image that extends in a left-right direction, and
determining 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 causing, by the controller, 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.
11 . The information terminal according to claim 1 , wherein
the specific operation includes a rotation instruction operation of the user on the display,
the controller performs movement control of the moving object while the rotation instruction operation is performed, and stops the movement control of the moving object when the rotation instruction operation is stopped,
the controller causes the display to display a fifth guidance image that prompts the rotation instruction operation, and
the controller causes the display to hide the fifth guidance image, when the rotation instruction operation is started.
