Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle control, and in particular relates to a screen interaction method that facilitates a driver to concentrate on driving. Background Art

[0002] With the rapid development of the economy, the concept of smart cockpits has become widely popular. The functions of in-car entertainment systems are becoming more and more numerous, more powerful, and more integrated, making cars a node in the Internet of Everything, breaking through the concept that cars are just means of transportation and extending the use of cars to all aspects of people's lives. Many people no longer regard cars as a means of transportation, but as a private place for rest and relaxation. Traditional mechanical dashboards and button controls are gradually being replaced by multi-touch displays. However, compared with traditional button controls, LCD screen click interaction lacks a feedback mechanism, and brings more complex interaction methods such as sliders, single selections, and multiple selections, which requires more attention to some functions of vehicle-computer interaction, thus causing safety hazards. Summary of the invention

[0003] The purpose of the present invention is to provide a screen interaction method that allows the driver to concentrate on driving, so that the main and front-passenger drivers can complete common functions with the same efficiency while reducing visual occupation; after proficient learning, the operation can be completed without looking at the screen; the time when the eyes are away from the road during operation can be reduced, making driving safer; at the same time, the addition of physical buttons is avoided, reducing vehicle development costs.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a screen interaction method that facilitates the driver to concentrate on driving, comprising:

[0005] When the central control touch screen detects an external touch operation, a detection is performed, and when the detection meets the first trigger condition, a first-level selection menu is expanded in a preset area;

[0006] After the first-level selection menu is expanded, a detection is performed. When it is detected that the second trigger condition is met within the first preset time, the first-level selection menu is replaced with a corresponding second-level selection menu at the first-level selection menu according to the selection options obtained by the detection; otherwise, the first-level selection menu is closed;

[0007] After the secondary selection menu is expanded, a detection is performed. When it is detected that the second trigger condition is met within the first preset time, a corresponding function is executed in the secondary selection menu according to the selection option obtained by the detection; otherwise, the secondary selection menu is closed.

[0008] The first trigger condition is: an external touch operation is detected in a preset hot zone; or a pressing operation is detected in any area of ​​the central control touch screen except the preset hot zone and lasts for more than a second preset time.

[0009] When an external touch operation is detected in the preset hot zone, a first-level selection menu is expanded in the center of the corresponding preset hot zone; when a continuous pressing operation exceeding a second preset time is detected in any area of ​​the central control touch screen except the preset hot zone, a first-level selection menu is expanded in the center of one side of the central control touch screen close to the pressing point position according to the pressing point position; wherein, the central control touch screen is divided into a left half screen and a right half screen along the longitudinal center line; the preset area includes the preset hot zone, the screen center of the left half screen of the central control touch screen, and the screen center of the right half screen of the central control touch screen.

[0010] When a continuous pressing operation exceeding a second preset time is detected in any area of ​​the central control touch screen except the preset hot zone, the first-level selection menu is a circular wheel-shaped menu.

[0011] The preset hot zone is the middle of the left and right edges of the central control touch screen. When an external touch operation is detected in the preset hot zone, a first-level selection menu is expanded in the center of the preset hot zone on one side of the half screen of the central control touch screen corresponding to the preset hot zone. The first-level selection menu is a semicircular wheel-shaped menu.

[0012] The method for defining the preset hot zone is: establish an xy two-axis coordinate system, which takes the lower left corner edge point of the central control touch screen as the coordinate origin, the vertical upward direction is the positive direction of the y axis, and the horizontal left direction is the positive direction of the x axis. The height of the central control touch screen is set to h and the width is w; define the area with x-axis coordinate ≤w / 12 or x-axis coordinate ≥11w / 12, and h / 3≤y-axis coordinate ≤2h / 3 as the preset hot zone.

[0013] When a continuous pressing operation exceeding the second preset time is detected in any area of ​​the central control touch screen except the preset hot zone, if the pressing area is in the central area of ​​the central control touch screen, that is, h / 3≤y-axis coordinate≤2h / 3, the first-level selection menu is directly expanded; if the pressing area is not in the central area of ​​the central control touch screen, a voice prompt is given, and the first-level selection menu is expanded after answering the voice prompt.

[0014] The second trigger condition is: detecting a finger sliding in any area of ​​the central control touch screen; or detecting that the user's finger stops contacting the primary selection menu or the secondary selection menu and touches the primary selection menu or the secondary selection menu again to select an option within a second preset time.

[0015] When a finger slide is detected in any area of ​​the central control touch screen, the polar angle of the sliding end point is obtained based on the polar coordinates formed by the line connecting the sliding start point and the sliding end point and the positive direction of the x-axis, and the corresponding selection option in the primary selection menu or the secondary selection menu is determined based on the polar angle of the sliding end point.

[0016] A computer-readable storage medium is also provided, on which a computer program is stored, and when the computer program is executed by a processor, the steps of any of the control methods described above are implemented.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The present invention allows the driver and the front passenger to complete common functions with the same efficiency while reducing visual occupation through the contact interaction between the user and the central control touch screen and the clear, easy-to-understand and convenient operation selection menu; after proficient learning, the operation can be completed without looking at the screen; the time when the eyes are away from the road during operation can be reduced, making driving safer; at the same time, the addition of physical buttons is avoided, reducing vehicle development costs.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] The technical solution of the present invention is:

[0027] Embodiment 1:

[0028] A screen interaction method that allows the driver to focus on driving, such as Figure 1 Shown include:

[0029] S1, when the central control touch screen detects an external touch operation, it performs a detection, and when the detection meets the first trigger condition, a first-level selection menu is expanded in a preset area;

[0030] S2. After the primary selection menu is expanded, a detection is performed. When it is detected that the second trigger condition is met within a first preset time (2 seconds in this embodiment), the primary selection menu is replaced with a corresponding secondary selection menu at the primary selection menu according to the selection options obtained by the detection; otherwise, the primary selection menu is closed;

[0031] S3. After the secondary selection menu is expanded, a detection is performed. When it is detected that the second trigger condition is met within the first preset time, a corresponding function is executed in the secondary selection menu according to the selection option obtained by the detection; otherwise, the secondary selection menu is closed.

[0032] The first trigger condition is: an external touch operation is detected in a preset hot zone; or a pressing operation is detected in any area of ​​the central control touch screen except the preset hot zone and lasts for more than a second preset time (2s in this embodiment).

[0033] When an external touch operation is detected in the preset hot zone, a first-level selection menu is expanded in the center of the corresponding preset hot zone; when a continuous pressing operation exceeding a second preset time is detected in any area of ​​the central control touch screen except the preset hot zone, a first-level selection menu is expanded in the center of one side of the central control touch screen close to the pressing point position according to the pressing point position; wherein, the central control touch screen is divided into a left half screen and a right half screen along the longitudinal center line; the preset area includes the preset hot zone, the screen center of the left half screen of the central control touch screen, and the screen center of the right half screen of the central control touch screen.

[0034] like Figure 4 As shown, when a continuous pressing operation exceeding a second preset time is detected in any area of ​​the central control touch screen except the preset hot zone, the first-level selection menu is a circular wheel-shaped menu.

[0035] The preset hot zone is the middle of the left and right edges of the central control touch screen. When an external touch operation is detected in the preset hot zone, a first-level selection menu is expanded in the center of the preset hot zone on one side of the half screen of the central control touch screen corresponding to the preset hot zone. The first-level selection menu is a semicircular wheel-shaped menu.

[0036] The method for defining the preset hot zone is: establish an xy two-axis coordinate system, which takes the lower left corner edge point of the central control touch screen as the coordinate origin, the vertical upward direction is the positive direction of the y axis, and the horizontal left direction is the positive direction of the x axis. The height of the central control touch screen is set to h and the width is w; define the area with x-axis coordinate ≤w / 12 or x-axis coordinate ≥11w / 12, and h / 3≤y-axis coordinate ≤2h / 3 as the preset hot zone.

[0037] When a continuous pressing operation exceeding the second preset time is detected in any area of ​​the central control touch screen except the preset hot zone, if the pressing area is in the center area of ​​the central control touch screen, that is, h / 3≤y-axis coordinate≤2h / 3, Figure 2As shown, directly expand the first-level selection menu; if the pressed area is not in the central area of the central control touch screen, a voice prompt will be given, and after answering the voice prompt, the first-level selection menu will be expanded.

[0038] The second trigger condition is: detecting a finger swipe in any area of the central control touch screen; or detecting that the contact operation of the user's finger with the first-level selection menu or the second-level selection menu stops and then touching the first-level selection menu or the second-level selection menu again within the second preset time to select an option.

[0039] When it is satisfied that a finger swipe is detected in any area of the central control touch screen, obtain the polar angle of the sliding end point according to the polar coordinates formed by the line connecting the sliding start point and the sliding end point and the positive direction of the x-axis, and determine the corresponding selection option in the first-level selection menu or the second-level selection menu according to the polar angle of the sliding end point.

[0040] According to Figure 3 The example operation steps are as follows:

[0041] Step 1: Detect when an external touch operation is detected on the central control touch screen. Denote the height of the in-vehicle computer screen as h and the width as w. In the following text, the horizontal axis coordinate of any coordinate is x, and the vertical axis coordinate is y.

[0042] Step 1.1: If the touch clicks on the preset hot zone (the two side areas of the screen, x ≤ w / 12 or x ≥ 11w / 12, h / 3 ≤ y coordinate ≤ 2h / 3), then expand the quick jump half-disc menu from the default position of the center points on both sides of the screen.

[0043] Step 1.2: If the clicked area is not the preset hot zone and the screen is continuously pressed at any position for more than 2 seconds, then obtain the current pressed point coordinates.

[0044] Step 1.2.1: If it is located in the central area of the screen horizontally (w / 12 < x < 11w / 12, h / 3 ≤ y ≤ 2h / 3), expand the full disc menu centered on the click position. The specific expansion rule is: when the pressed point is in the left half (including the midline) of the screen, the menu expands to the right, and when the pressed pad is in the right half, the menu expands to the left. After that, whether the finger swipes or lifts and drops, it is regarded as an operation on the disc menu.

[0045] Step 1.2.2: If the pressed point is outside the central area (y < h / 3 or y > 2h / 3), a voice prompt will be given to indicate that the position for calling out the menu needs to be adjusted.

[0046] Step 1.3: If the area outside the hot zone is quickly clicked (not in the hot zone and the pressing time is less than 2 seconds), then normally use the corresponding function module area on the in-vehicle computer screen.

[0047] Step 2: Detect the direction of the user's finger swipe or the location where the finger is lifted and then dropped, and determine the disc menu option corresponding to the movement end point.

[0048] Step 2.1 If the user slides his finger, the polar angle of the end point is obtained by using the line segments of the sliding start and end points and the horizontal x-axis to the right. The corresponding disc option is inserted into the corresponding functional area according to the polar angle:

[0049] Step 2.1.1 If the current option has a submenu (including page turning), expand the secondary disc menu according to the current page layout and option position.

[0050] Step 2.1.2 If there is a setting item for the current option, convert the position of the finger on the screen into polar coordinates, obtain the detailed value of the setting item and apply it.

[0051] Step 2.1.3 If the user moves his finger toward the edge of the screen (covering the entire half quadrant), the previous menu will return to the previous menu or exit the menu from the first-level selection menu. If the current menu is a semicircular disk at the edge of the screen, the action of sliding the finger out of the screen is considered to exit the first-level selection menu. If you click "Previous Page", the previous menu will return to the previous menu at its original position.

[0052] Step 2.1.4 If the user does not enter the submenu / option when releasing the finger and is still in the circular area, a voice prompt will be played and the menu will be closed.

[0053] Step 2.2 If the user lifts his finger and clicks again, the landing point is used to determine:

[0054] Step 2.2.1 If the point is in the circular menu area, enter the corresponding option according to the click position, execute the setting item, or return to the previous menu;

[0055] Step 2.2.2 If the landing point is outside the menu area, exit the circular menu.

[0056] Step 2.3 If the user's finger is not detected to move within the preset time (2s), a voice prompt will be given that no operation is currently being performed in the menu. If there is still no operation after 5s, the circular menu will be exited.

[0057] The specific rules for expanding the circular shortcut menu are as follows:

[0058] To ensure accurate clickability without visual inspection and to support at least 2 levels of menu extension, the circular menu is always composed of 3 parts:

[0059] 1. The center area is circular, with a radius less than or equal to 1 / 12 of the length of the short side of the screen (denoted as r). To optimize visual effects and interaction efficiency, the maximum value is selected. For example, on a typical 15.6-inch (1920·1080px) screen, the maximum radius r is 90px. On a 1920·1200 resolution screen, the maximum radius is 100px. On a 1080·1920 vertical screen, the radius is 90px.

[0060] 2. The lower level menu / action execution component is formed by extending concentric circles based on the center point of the upper level selection menu to form a ring, which is evenly divided on the side close to the center of the screen.

[0061] 2.1 If you expand the sub-menu:

[0062] 2.1.1 The outer diameter of the circle = 2r, and the inner diameter = r + l. l is the spacing reserved to ensure that the upper and lower menus are clearly distinguished, which can be adjusted according to the actual situation such as screen size and HMI rules. (The condition l < (1-step in22.5°) h / (12 · step in22.5°) ≈ 0.134h must be met to ensure that the screen range will not be exceeded when the second and third level menus are subsequently extended. Since 1 obviously will not exceed r = h / 12, this condition is met by default.) For example, if the spacing y = 10px is taken on a typical 15.6-inch screen, the outer diameter of the lower menu circle is 180px and the inner diameter is 100px.

[0063] 2.1.2 In general, to ensure the UI text area, the number of options at each level of the shortcut menu is at least 2 and at most 4, and the hot zone divides the sector 180 degrees to the right of the option center. When the number of sub-options of a disc option may be more than 4, set the page turning button area at the top and bottom of the ring, or set a separate page for it to avoid too many elements and reduce the interaction efficiency. In actual use, try to avoid more than 4 options.

[0064] 2.1.3 The hot zone of the return / undo button of the shortcut menu is a ring formed by extending concentric circles based on the center point of the previous level selection menu, and is located on the side close to the center of the screen.

[0065] 2.1.4 Leave a 5° gap between the UI components actually presented for each option (including return). For example, in a menu containing 4 options, the horizontal right direction is 0°, and the gaps are located at positions -92.5° to -87.5°, -47.5° to -42.5°, -2.5° to 2.5°, 37.5° to 42.5°,

[0066] 87.5° to 92.5° range.

[0067] 2.2 If you expand the action component: Based on the principle of quick modification of disc operation, the following common components are converted into polar coordinate operations to achieve convenient operation and reduce visual occupation, such as Figure 5 Some of the features are shown:

[0068] 2.2.1 Switch: The on / off option divides the screen into two 175° sectors on the center side, and the rules are similar to expanding two sub-menus.

[0069] 2.2.2 Buttons / gear adjustment / multiple options: Divide the screen into a 175° sector on the center side, with similar rules to expand multiple sub-menus.

[0070] 2.2.3 Slider bar: Its hot zone is a 175° fan-shaped area on the center side of the entire screen, and the actual width of the slide rail can be reduced.

[0071] 3. Whenever an option is selected in the next level selection menu of the shortcut menu, the midpoint of the edge of the circle of the option part before the next level menu is expanded is taken as the new center of the circle, forming the center circle of the new level selection menu. This design is intended to prevent the new center circle from deviating too much from the finger position, while ensuring that when the user clicks close to the edge of the wake-up hot zone, the expanded second level selection menu can still be fully displayed on the screen.

[0072] a) Take the calculation formula of a menu expansion with 4 options as an example: the coordinates of the center point of the circle of the upper menu (a, b), the radius of the center point of the circle r, the spacing between the first and second level selection menus l, when clicking the first option clockwise, the coordinates of the center point of the part of the circle before the sub-menu is expanded (c, d), and the position of the center point of the new expanded circle is (e, f). Then c = a + co step 22.5° · 1.5r; d = b + step in 22.5° · 1.5r; e = a + co step 22.5° · (r + l); f = a + step in 22.5° · (r + l)

[0073] b) Based on the above considerations, take a 4-option menu expansion as an example. On a 15.6-inch screen, take the lower left corner as the 0 point of the rectangular coordinate system, click (100, 600) to generate the menu, the center of the first-level selection menu is at (100, 600), and the spacing between the first / secondary selection menus is 10px. Applying the above formula, we know that the center point of the first option of the second-level selection menu is (75.56, 672.58) and (100, 790).

[0074] 4. The shortcut menu should support 2-3 levels of expansion.

[0075] To further reduce visual occupancy, you can optionally add interactive feedback to the following behaviors, such as Figure 6 As shown:

[0076] 1. When a new option is selected and pressed, the user is prompted to select the corresponding option through voice broadcast

[0077] 2. The car computer / screen vibrates when a new option is selected, giving the user feedback on successful interaction; different vibration intensities are provided for different options such as sliders, confirmation and denial buttons, so that users can get accurate operation feedback through tactile sensation.

[0078] More preferably, the in-car camera recognizes gestures through the OM step / DM step to activate the circular menu, determines the direction and completes the gesture interaction, so that the user does not need to accurately pre-position the hand on the screen.

[0079] Furthermore, you can customize the order and supported functions of the shortcut bars at each level of the circular menu in the settings.
