Display control device and display control method
A display control device includes a display and a controller. The display is configured to be installed in a vehicle and capable of touch operation. The controller configured to control an image displayed on the display. The controller detects a start trigger indicating that a user has started scrolling to the left or right on the display, and increases a relative position between a tile and an icon at a prescribed acceleration with a passage of time from detection of the start trigger. The controller detects a stop trigger indicating that the user has stopped scrolling, and reduces the relative position between the tile and the icon at a prescribed deceleration with a passage of time from detection of the detected stop trigger.
1. A display control device comprising: a display configured to be installed in a vehicle and capable of touch operation; and a controller configured to control an image displayed on the display,
the display being configured to display a tile that activates an application by a user's touch, and an icon related to the application, at least a part of the icon is displayed as overlapping the tile, and
the controller being configured to
detect a start trigger indicating that a user has started scrolling left or right on the display,
increase a relative position between the tile and the icon at a prescribed acceleration with a passage of time from detection of the start trigger,
detect a stop trigger indicating that the user has stopped scrolling, and
decrease the relative position between the tile and the icon at a prescribed deceleration with a passage of time from detection of the stop trigger.
2. The display control device according to claim 1 , wherein
the relative position between the tile and the icon is represented by a quadratic function.
3. The display control device according to claim 1 , wherein
a plurality of the tiles and the icons are displayed on the display, and
the controller is configured to
increases distance between adjacent tiles at the prescribed acceleration with the passage of time from the detection of the start trigger, and
decreases the distance between the adjacent tiles at the prescribed deceleration with the passage of time from the detection of the stop trigger.
4. The display control device according to claim 1 , wherein
the controller is configured to first move the tile first at the prescribed acceleration and then move the icon at the prescribed acceleration upon detection of the start trigger.
5. The display control device according to claim 1 , wherein
upon the controller detecting the scrolling in a different direction by the user while moving at least one of the tile and the icon, the controller is configured to decrease the relative position of the tile and the icon,
then the controller is configured to stop movement of the tile and the icon, and
then the controller is configured to move the tile and the icon at the prescribed acceleration in different directions to increase the relative position between the tile and the icon.
6. The display control device according to claim 1 , wherein
the controller is configured to tilt an orientation of the tile in a direction of movement when moving the tile.
7. The display control device according to claim 1 , wherein
a center position of the tile and a center position of the icon do not coincide in the horizontal direction of the display.
8. The display control device according to claim 1 , wherein
the stop trigger is a detection signal indicating that the user has removed a finger from the display.
9. The display control device according to claim 1 , wherein
at least one of the prescribed acceleration and the prescribed deceleration increases as a speed or an acceleration of the scrolling by the user increases.
10. The display control device according to claim 1 , wherein
a maximum value of the relative position increases as the speed or acceleration of scrolling by the user increases.
11. A display control method for display control device comprising a display configured to be installed in a vehicle and capable of touch operation and a controller for controlling an image displayed on the display, wherein
displaying a tile that activates an application by a user's touch, and an icon related to the application,
at least a part of the icon being displayed as overlapping the tile, and
the controller
detecting a start trigger indicating that a user has started scrolling left or right on the display,
increasing a relative position between the tile and the icon at a prescribed acceleration with a passage of time from detection of the start trigger,
detecting a stop trigger indicating that the user has stopped scrolling, and
reducing the relative position between the tile and the icon at a prescribed deceleration with a passage of time from detection of the stop trigger.
