In the related art, a plurality of buttons or a plurality of operation mechanisms are usually required to be arranged in the in-vehicle device for performing interactive operation, wherein each button corresponds to a different instruction. For example, one button is an instruction for causing a cursor to move a large range across a function region on a screen, and one button is an instruction for causing a cursor to move a small range within a certain function region on a screen. However, if the number of device buttons is too large, the structure of the in-vehicle device becomes complicated, and the operation complexity increases.

FIG. 2 shows a flow diagram of a method of user interface operation, according to an embodiment of the present disclosure.

As shown in fig. 2, the user interface includes a first display area for displaying a first plurality of objects and a second display area for displaying a second plurality of objects, and wherein the user interface is provided with a cursor moving device, the method comprising: step S201, responding to a first operation of a user on the cursor moving device along a first direction, moving the cursor according to a sequence corresponding to the first direction to select a first object in the first plurality of objects; and a step S202, in response to a second operation of the cursor moving device by the user along the first direction and in response to determining that the first object is the last object in the first plurality of objects in the order, moving the cursor to select a second object in the second plurality of objects.

When using an electronic device with a display screen (e.g., a car-mounted device), a user can arrange application software in the device according to software types, for example, icons of video software are collectively placed in a certain area of the display screen and are used as a video software area, i.e., the first display area, or icons of navigation software are collectively placed in another area of the display screen and are used as a navigation software area, i.e., the second display area. It should be understood that, in the above partitioning process, the user is not limited to be involved, and different areas may be set in the original factory. When a user wants to watch a video, the corresponding software is selected from the video software area to run quickly, and the situation that the needed software is not easy to find quickly due to disorder arrangement of various types of software is avoided.

When the display area is too small and the number of software icons serving as the objects is too large, the display area cannot simultaneously display all the software icons, and traversal needs to be realized by operating the knob, so that icons which are not displayed originally appear in the display area.

Illustratively, the user interface may be a display screen of the in-vehicle device. In reality, some car-mounted devices adopt a combination of a non-touch screen and an entity button, and a user interacts with the car-mounted devices through operation of the entity button. It can be understood that, due to the physical buttons, the user cannot directly select the required software through clicking operation. Therefore, in a scenario of using the entity button, it is necessary to remind the user whether the required software is accurately selected by a cursor, where the cursor may be a focus point, a software icon as the focus point is enlarged and displayed, and the cursor may also be a dotted line frame, and the software icon as the focus point is surrounded by the dotted line frame. The user may select various cursors according to preferences.

In this embodiment, the physical buttons may be implemented as knobs. If the knob is rotated clockwise, the cursor in the interface may sequentially select the corresponding icons, but is not limited thereto.

For example, when the user wishes to start the navigation function, the cursor can be moved from the video software area to the navigation software area only by a rotation operation. In the process, the user only needs to use the rotary button, so that only one entity button can be arranged, the operation mode is simplified to single rotary operation, and the user can use the car machine equipment by going to the home without learning.

According to some embodiments, the first display region comprises a first number of display positions, and the method further comprises: in response to a third operation of the cursor movement device by the user in the first direction, moving the cursor in the order to select a third object of the first plurality of objects, wherein the third object is displayed at a last display position in the order of the first number of display positions; and in response to a fourth operation by the user of the cursor movement device in the first direction and in response to determining that the number of objects of the first plurality of objects that follow the third object in the order is not less than the first number, refreshing the first display area to display the first number of objects in the order from the third object.

As previously mentioned, in some cases, the screen cannot display all icons simultaneously, and for a large number of icons that are not displayed in the screen, if only one new icon is updated into the screen at a time, the user needs to perform multiple rotations of the knob to switch to the target icon. The present disclosure addresses this issue by updating a plurality of icons simultaneously in response to a scrolling operation by a user, thereby speeding up the efficiency with which the user browses icons.

According to some embodiments, in response to a fifth operation of the cursor moving device by the user in the first direction and in response to a determination that the number of objects of the first plurality of objects that are located after the third object in the order is less than the first number, the plurality of objects displayed in the first display region are respectively moved by one display position in a reverse direction of the order, and a next object located after the third object in the order is displayed at the last display position.

In an actual scene using the car machine equipment, a user often has misoperation of rotating too much in the process of browsing icons, and at the moment, if the sensitivity of icon updating is too high, a target icon is lost. Setting a precise scrolling mechanism: when an icon near the end of the display area is updated, the update speed of the icon is slowed down, thereby preventing the focus from being switched to the wrong display area due to a user's misoperation.

According to some embodiments, the first plurality of objects is stored as a first bidirectional child chain table, wherein the first bidirectional child chain table comprises two first empty nodes at ends and a first plurality of object nodes between the two first empty nodes, wherein the first plurality of object nodes respectively correspond to the first plurality of objects; the second plurality of objects is stored as a second bidirectional child chain table, wherein the second bidirectional child chain table includes two second empty nodes at ends and a second plurality of object nodes between the two second empty nodes, wherein the second plurality of object nodes respectively correspond to the second plurality of objects; and wherein the first bidirectional child chain table and the second bidirectional child chain table are associated with a first parent node and a second parent node, respectively, of a parent chain table.

Therefore, the storage position sequence of the data can correspond to the arrangement sequence of the icons in the interface, so that the corresponding data can be read quickly in response to the operation of moving the cursor by a user.

And the last node in the first sublink along the second direction is a null node.

According to some embodiments, a linked list structure comprising the parent linked list, a first bidirectional child list, and a second bidirectional child list is provided with a parent pointer and a child pointer, and wherein said moving the cursor to select a second object of the second plurality of objects in response to a second operation of the cursor movement device by the user in the first direction and in response to determining that the first object is a last object of the first plurality of objects in the order comprises: in response to determining that the first object node corresponding to the first object is the last object node in the first bidirectional child list in the order, moving the parent pointer from the first parent node to the second parent node and moving the child pointer to a second object node in the second bidirectional child list corresponding to the second object.

Corresponding pointers are provided for both the case where the focus (cursor) moves between different areas and the case where the cursor moves between the same areas, thereby facilitating the data required for the focus to be quickly read by the pointers.

Illustratively, when the knob is rotated clockwise, the pointer points to the next node and the cursor moves downward, and when the knob is rotated counterclockwise, the pointer points to the previous node and the cursor moves upward.

Fig. 3 shows a block diagram of a structure of a user interface operation apparatus according to an embodiment of the present disclosure.

According to some embodiments, the first display area comprises a first number of display positions, the apparatus further comprising: a third unit configured to move the cursor in the order to select a third object of the first plurality of objects in response to a third operation of the cursor moving device in the first direction by the user, wherein the third object is displayed at a last display position in the order among the first number of display positions; and a fourth unit configured to refresh the first display area to display the first number of objects in the order from the third object in response to a fourth operation of the cursor moving device in the first direction by the user and in response to a determination that the number of objects located after the third object in the order among the first plurality of objects is not less than the first number.

According to some embodiments, the apparatus further comprises: a fifth unit configured to, in response to a fifth operation of the cursor moving device by the user in the first direction and in response to a determination that the number of objects positioned after the third object in the order among the first plurality of objects is smaller than the first number, respectively move the plurality of objects displayed in the first display area by one display position in a reverse direction of the order and display a next object positioned after the third object in the order at the last display position.

It will be appreciated that the icons described above need to be displayed in the display screen by way of a view. Wherein the view is an existing program system that displays data in a device display screen in a visual manner. And the view is a visual operating system for user interaction and data display, and is not limited to an android view control, and may also be, for example, a Windows operating system. By inputting data containing one or more icons into the view, the corresponding icons are displayed in the screen. Through the view, the user can run the application program in a visualized operation. Herein, the object of the display area is an icon of an application program, and the icon of the application program is displayed in the display area of the display screen through the view. The view may also retrieve data related to the displayed focus (cursor) and display the focus (cursor) in the display screen.
