Terminal and method for controlling terminal

A terminal comprising:

• a processor;
• a touch panel that displays an image and accepts a touch operation;
• and
• a housing,
• wherein the processor
• causes the touch panel to display a vehicle control screen on which an operation button allowing the touch operation is displayed, moves a position of the operation button following a movement of a position of the touch operation, and maintains a state where the touch operation is performed on the operation button when the position of the touch operation moves after the touch operation is performed on the operation button displayed on the vehicle control screen, and
• transmits a propulsion instruction signal instructing propulsion of a vehicle to the vehicle while the touch operation is being performed on the operation button displayed on the vehicle control screen, and stops transmission of the propulsion instruction signal in response to ending of the touch operation on the operation button,
• wherein the processor functions as a housing state detection circuit that detects a state of the housing,
• wherein the processor
• acquires imaging data that is based on a result of imaging of a camera provided in the vehicle while the vehicle control screen is being displayed, causes the touch panel to display an image based on the acquired imaging data, and displays the operation button in a superposed manner on the image based on the imaging data,
• changes the image to be displayed on the touch panel in accordance with a state of the housing detected by the housing state detection circuit and maintains display of the operation button even when the image to be displayed on the touch panel is changed,
• wherein the processor
• causes the touch panel to display an overhead image which is an image of a bird's eye view of the vehicle as the image based on the imaging data when the housing state detection circuit detects that an orientation of the housing is placed in a first orientation, and
• causes the touch panel to display an outside-of-vehicle image which is an image of an outside of the vehicle imaged by the camera as the image based on the imaging data when the housing state detection circuit detects that the orientation of the housing is placed in a second orientation that is different than the first orientation.

A method of controlling a terminal that includes a touch panel that displays an image and accepts a touch operation, the method comprising:

• displaying, on the touch panel, a vehicle control screen on which an operation button allowing the touch operation is displayed and moving a position of the operation button following a movement of the position of the touch operation, and maintaining a state where the touch operation is performed on the operation button when the position of the touch operation moves after the touch operation is performed on the operation button displayed on the vehicle control screen;
• transmitting a propulsion instruction signal instructing propulsion of a vehicle to the vehicle while the touch operation is being performed on the operation button displayed on the vehicle control screen and stopping transmission of the propulsion instruction signal in response to ending of the touch operation on the operation button;
• causing the touch panel to display a lock screen on which a slide bar being a strip-shaped object and a slide button are displayed, the slide button being positioned at one end of the slide bar, moving along the slide bar in accordance with a swipe operation, which is an operation of moving the position with which a finger is in contact with while maintaining the state where the finger is in contact with the touch panel, and moving to the one end of the slide bar in response to ending of the swipe operation;
• displaying the lock screen in which the vehicle control screen is covered by a dark-colored mask image as a background, and making the color of the mask screen covering the vehicle control screen lighter as the slide button moves from the one end to the other end of the slide bar;
• and
• changing a screen to be displayed on the touch panel from the lock screen to the vehicle control screen when the slide button is positioned at another end of the slide bar by the swipe operation for a predetermined period of time and changing the slide button positioned at the other end of the slide bar to the operation button so as to cause the slide button to function as the operation button.
