Definitions

  • This case concerns a display device that displays information on variables that reflect the state of a vehicle.
  • a meter device that imagines a virtual solid object that can rotate around a specified rotation axis, and draws a projection of the solid object so that the angle of rotation changes according to the power output and vehicle speed.
  • a display format that uses such a projection is suitable for presenting various information in a compact manner compared to existing analog meters (see Patent Document 1).
  • reference numbers are printed to make it easier to read the size of the rotation angle.
  • the image of this reference number is mapped onto the surface of the solid object as a planar texture. Therefore, if the surface on which the reference numbers are attached is significantly inclined with respect to the projection surface, the shape of the reference numbers projected onto the projection surface will be distorted, and good visibility will not be obtained. For example, in the case of the horizontally oriented cylindrical meter described in Patent Document 1, it is difficult to correctly read the reference numbers displayed near the top and bottom ends of the cylindrical surface.
  • One of the objectives of this case was devised in light of the above-mentioned problems, and is to provide a display device with improved visibility. However, this objective is not the only objective. Another objective of this case is to achieve effects that cannot be obtained with conventional technology, which are derived from the configurations shown in the "Mode for carrying out the invention" described below.
  • the disclosed display device can be realized as the aspects (application examples) disclosed below, which solve at least part of the above problems.
  • Each of the aspects from aspect 2 onwards is an aspect that can be selected additionally as appropriate, and each of the aspects can be omitted. None of the aspects from aspect 2 onwards discloses an essential aspect or configuration for the present case.
  • the disclosed display device is a display device that displays a projection of a solid object that rotates according to the value of a variable related to a vehicle state, and includes a reference scale and a reference number.
  • the reference scale is a mark drawn on the peripheral surface surrounding the rotation axis of the solid object as an indication of the magnitude of the rotation angle relative to a predetermined origin.
  • the reference number is disposed in a position adjacent to the reference scale on the projection, represents the value of the variable corresponding to the reference scale, and is drawn to follow the reference scale while maintaining a posture facing directly toward the projection surface of the projection.
  • the peripheral surface has a visible surface that is displayed on the projection surface and a non-visible surface that is not displayed on the projection surface. It is also preferable that, as the solid body rotates, when the reference scale moves from the non-visible surface to the visible surface, the reference numbers corresponding to the reference scale are drawn to appear, and when the reference scale moves from the visible surface to the non-visible surface, the reference numbers corresponding to the reference scale are drawn to disappear.
  • aspects including aspect 1 above it is preferable that the color of the reference number corresponding to the reference scale is set according to the position of the reference scale on the peripheral surface.
  • Aspect 5 In regard to the aspects including Aspect 4 described above, it is preferable that the reference numerals are drawn in a character color of a second color different from the first color, and that the characters are surrounded by an outline of a third color different from the second color.
  • Aspect 6 In relation to the aspects including Aspect 4 above, it is preferable to have a first pointer that is drawn in a shape extending from the current point toward the vicinity of the rotation axis.
  • Aspect 9 In relation to aspects including aspect 8 above, it is preferable to have a first pointer drawn in a shape extending linearly from the current point toward the rotation axis, and a current value display unit that is disposed adjacent to the end of the first pointer on the opposite side from the current point and displays the current value of the variable in numbers. It is also preferable that the current value display unit is displayed with priority over the second pointer on the projection surface.
  • the disclosed display device renders the reference numbers so that they follow the reference scale while maintaining a posture facing the projection surface of the projection drawing. This improves the visibility of the reference numbers regardless of the position of the reference scale. This makes it easier for the user to correctly read the rotation angle, for example, improving the user experience.

  • FIG. 4 is a projection diagram showing the configuration of a cylinder 7 that is the prototype of the images of the power meter 4 and the speedometer 5.
  • the cylinder 7 is a solid body that rotates around a rotation axis C according to the values of variables related to the vehicle state.
  • the cylinder 7 has a peripheral surface 8 that surrounds the rotation axis C, and two top surfaces 9 that intersect with the rotation axis C.
  • the peripheral surface 8 has a visible surface 31 that is displayed in the projection diagram, and a non-visible surface 32 that is not displayed in the projection diagram. For one cylinder 7, only one of the top surfaces 9 and the visible surface 31 are depicted in the projection diagram.
  • the rotation axis C is set, for example, to extend horizontally (left and right direction of the display screen) in the projection diagram.
  • the cylinder 7 shown in FIG. 5 has a number line 30, a current point 34, a center point 35, a current line 36, and an origin line 37.
  • the number line 30 corresponds to the intersection of the peripheral surface 8 with a plane that is perpendicular to the axis of rotation C and passes through a predetermined origin 33.
  • the reference scale 11 is positioned based on the number line 30, and is drawn so as to be tangent to one side of the number line 30 (the right side of the number line 30 in FIG. 5), for example.
  • the current point 34 is a point on the number line 30 that corresponds to the current value of the vehicle speed.
  • the movement of the reference numbers 12 relative to the reference scale 11 drawn on the circumferential surface 8 of the rotating cylinder 7 can be understood in analogy with the movement of a gondola (passenger passenger compartment, cabin) rotatably supported on the rim (annular frame) of a rotating Ferris wheel.
  • the gondolas of a Ferris wheel always move in a position where the floor is horizontal, regardless of the rotation angle of the rim.
  • the reference numbers 12 move to follow the reference scale 11, always in a position that appears to be drawn on a plane parallel to the projection surface, regardless of the rotation angle of the cylinder 7.
  • the first pointer 21 is an indicator drawn in a shape extending from the current point 34 toward the vicinity of the rotation axis C.
  • the first pointer 21 is drawn, for example, in a wedge shape with one end on the current point 34 side being thick and the other end being thin.
  • the other end of the first pointer 21 is preferably disposed near the center point 35 of the top surface 9, and more preferably coincides with the center point 35.
  • the first pointer 21 plays a role in making it easier for the user to focus the line of sight on the current point 34. For example, when the user directs his or her line of sight toward the vicinity of the top surface 9 of the cylinder 7, the end portion on the current point 34 side is more likely to be noticed.
  • the position of the first pointer 21 in this embodiment is always fixed with respect to the projection surface, but it may be drawn to move according to the rotation speed or angular velocity of the circumferential surface 8.
  • the first pointer 21 pivoted to the center point 35 may be drawn to swing according to the rotation speed or angular velocity of the circumferential surface 8.
  • the second pointer 22 is an indicator needle that is drawn in the shape of an arc extending from the current point 34 to the origin 33 along the number line 30.
  • the second pointer 22 is drawn, for example, in a wedge shape with one end on the current point 34 side being thick and the other end on the origin 33 side being thin.
  • the length of the second pointer 22 expands and contracts according to the rotation angle of the cylinder 7, and the larger the current value of the variable (vehicle speed), the longer it is drawn.
  • the second pointer 22 plays a role in making it easier for the user to focus their gaze on the current point 34. For example, when the user moves their gaze along the number line 30, the end on the current point 34 side is more likely to be noticed.
  • the region of the visible surface 31 other than the first band 24 becomes the second band 25.
  • the first belt portion 24 is shaded and the second belt portion 25 is shown with lattice lines. Also, by changing the density of the lattice lines of the second belt portion 25, a color gradation, which will be described later, is expressed.
  • Lightness refers to the degree of brightness of a color (the degree to which white is mixed in the achromatic components). The higher the lightness, the more whitish the color, and the lower the lightness, the more blackish the color. It is preferable that the first color contains a lot of achromatic components, and it is preferable that the lightness and saturation are set low, for example.
  • the first color (the color of the first band portion 24) is a dark gray color close to black, and the background of the cylinder 7 is a color close to the first color (e.g., black).
  • the second band portion 25 is preferably drawn in a color different from the first color, and is preferably set to a color that clearly defines the boundary with the first band portion 24.
  • the second band portion 25 is preferably set to a higher brightness and saturation than the first color at the boundary with the first band portion 24.
  • the second band portion 25 in this embodiment is drawn with a gradation so that the color difference with the first color increases as it approaches the current point 34. Gradation means that the color changes continuously and stepwise in response to a change in position.
  • Color difference is a value that quantifies the perceived color gap between two colors, and is calculated, for example, based on the measurement method of JIS Z 8729-1980 (CIE L*a*b* color system ⁇ 1976>).
  • a color can be defined as the coordinates of a point in a multidimensional space (color space). For example, when colors are expressed using HSV (hue, saturation, brightness) or RGB (red, green, blue), the color space becomes three-dimensional, and a color corresponds to the coordinates of a point with three parameters. Therefore, color difference can be quantitatively calculated as the Euclidean distance between two points in a three-dimensional space.
  • FIG. 7 is a virtual planar development of second band 25.
  • the shape of the developed second band 25 is a rectangle whose width and height are determined by current line 36 and number line 30.
  • the point diagonally opposite current point 34 is defined as diagonal point 38
  • the right end point of current line 36 (the end point that is not current point 34) is defined as second current point 39.
  • the side connecting diagonal point 38 and second current point 39 (the side opposite number line 30) is defined as opposite line 40.
  • the color difference from the first color increases as one approaches the number line 30, and the color difference from the first color decreases as one approaches the counter line 40.
  • the color near the current point 34 is off-white, and the color near the second current point 39 is gray. If the color difference is large above and below the current line 36, the boundary with the first band 24 becomes clear, making it easier to grasp the current point 34. Therefore, it is preferable that a certain degree of color difference from the first color is maintained not only near the current point 34 but also near the second current point 39. In other words, it is preferable that the color near the second current point 39 is a color different from the first color.
  • the color near the current point 34 is off-white
  • the color near the origin 33 is gray
  • the diagonal point 38 is the same color as the first color (a dark gray that is close to black).
  • the entire primitive line 37 may be the same color as the first color. Setting a gradation like this highlights the contrast between the first band 24 and the second band 25, and the user's gaze is more likely to be drawn to the area around the current point 34 where the color difference is greater.
  • the first pointer 21, second pointer 22, and third pointer 23 are drawn on a layer higher than the projection of the cylinder 7, the first band portion 24, and the second band portion 25.
  • the color of these pointers 21 to 23 is preferably a second color different from the first color.
  • the second color (the color of the pointers 21 to 23) is white. This allows the boundary between the first band portion 24 and the second band portion 25 and the positions of the reference scale 11 indicated by the pointers 21 to 23 to be clearly displayed.
  • the colors of the first pointer 21, the second pointer 22, and the third pointer 23 may be a gradation color so that the color difference from the first color increases as the pointer approaches the current point 34.
  • a gradation may be set so that the color is the second color (white) near the current point 34, and the color becomes closer to the first color (dark gray or black) as the pointer moves away from the current point 34.
  • Such a gradation may be set for any of the first pointer 21, the second pointer 22, and the third pointer 23, or for all of the pointers 21 to 23.
  • the current value display section 26 and the current status display section 27 are drawn on a layer higher than the projection of the cylinder 7 and the pointers 21 to 23.
  • the current value display section 26 and the current status display section 27 are displayed with priority over the second pointer 22 on the projection surface.
  • the color of the current value display section 26 and the current status display section 27 is preferably the same color as the first pointer 21, which is the second color. This clearly shows the relationship between the contents of the current value display section 26 and the current status display section 27 and the position of the reference scale 11 pointed to by the first pointer 21.
  • the origin 33 is located below the bottom edge of the current value display section 26, so the entire second pointer 22 is drawn.
  • the origin 33 is located above the bottom edge of the current value display section 26, so the second pointer 22 is drawn as if it were discontinued at the bottom edge of the current value display section 26. If the origin 33 is located above the top edge of the current value display section 26, then only the portion of the second pointer 22 that is covered by the current value display section 26 may be omitted, or the entire portion above the bottom edge of the current value display section 26 may be omitted.
  • the reference scale 11 is drawn on the same layer as the projection of the cylinder 7. Therefore, when the reference scale 11 overlaps with the pointers 21 to 23, the reference scale 11 will be hidden by the pointers 21 to 23. In contrast, the reference numbers 12 are drawn on the top layer, which is higher than all other elements. In this way, even if the reference numbers 12 overlap with the pointers 21 to 23, the reference numbers 12 are always visible.
  • the color of the reference scale 11 is preferably a color different from the first color, and more preferably a second color (white).
  • the color of the reference numbers 12 is preferably a color different from the first color, and more preferably a second color (white).
  • the color of the reference numerals 12 is preferably set according to the position on the circumferential surface 8 of the reference scale 11 adjacent to that reference numeral 12. For example, the closer the position of the reference scale 11 is to the upper or lower end of the circumferential surface 8, the more preferably the reference numerals 12 are drawn in a color with a smaller color difference from the first color. Alternatively, the closer the position of the reference scale 11 is to the boundary between the visible surface 31 and the non-visible surface 32, the more preferably the reference numerals 12 corresponding to that reference scale 11 are drawn lighter. The closer the position of the reference scale 11 is to the vertical center on the circumferential surface 8, the more preferably the color of the reference numerals 12 is set to a color with a larger color difference from the first color.
  • an outline or outline color may be applied around the reference numerals 12.
  • the character color of the reference numerals 12 may be a second color (white), and an outline of a third color different from the second color may be drawn around the characters.
  • the third color is black. This improves the visibility of the reference numerals 12 superimposed on the first band portion 24 and the second band portion 25. In addition, the numerals become easier to read even when the reference numerals 12 overlap the third pointer 23.
  • the display device 1 displays a projection of a cylinder 7 (a solid object) that rotates according to the value of a variable related to a vehicle state, and includes a reference scale 11 and reference numerals 12.
  • the reference scale 11 is a mark drawn on a peripheral surface 8 surrounding a rotation axis C of the cylinder 7 as an indicator of the magnitude of a rotation angle relative to a predetermined origin 33.
  • the reference numerals 12 are arranged at a position adjacent to the reference scale 11 on the projection, and are numerals that represent the value of the variable corresponding to the reference scale 11 and are drawn to follow the reference scale 11 while maintaining a posture facing directly toward the projection surface of the projection.
  • the above configuration improves the visibility of the reference numbers 12 regardless of the position of the reference scale 11. This makes it easier for the user to correctly read the rotation angle of the cylinder 7, for example, and makes it possible to accurately communicate the values of variables related to the vehicle state, such as vehicle speed and drive source output. This not only improves the visibility of the display device 1, but also improves ease of use and usability, improving the user experience.
  • Figures 9(A) and (B) are comparative examples in which the reference numerals 12 of the speedometer 5 shown in Figures 8(A) and (B) are mapped onto the peripheral surface 8 as a planar texture.
  • the shape of the reference numerals 12 will be distorted near the top and bottom ends of the peripheral surface 8, making it difficult to read the reference numerals 12 correctly.
  • the shape of the reference numerals 12 will not be distorted even near the top and bottom ends of the peripheral surface 8, improving the visibility of the reference numerals 12.
  • the peripheral surface 8 has a visible surface 31 that is displayed on the projection surface and a non-visible surface 32 that is not displayed on the projection surface.
  • the reference scale 11 moves from the non-visible surface 32 to the visible surface 31 as the cylinder 7 rotates, the reference numbers 12 corresponding to the reference scale 11 are drawn to appear.
  • the reference scale 11 moves from the visible surface 31 to the non-visible surface 32, the reference numbers 12 corresponding to the reference scale 11 are drawn to disappear.
  • the reference numerals 12 By drawing the reference numerals 12 in this way, it is possible to display only the reference numerals 12 that are close to the current variable value, making it easier to grasp the current variable value. Also, by making the reference numerals 12 appear and disappear while moving along the peripheral surface 8, the movement of the reference numerals 12 can be made to feel like a series of smooth, flowing movements, creating a sophisticated impression. This can therefore improve the user experience.
  • the color of the reference numerals 12 corresponding to the reference scale 11 is set according to the position of the reference scale 11 on the peripheral surface 8. For example, as shown in Figs. 3(A), (B) and 5, the closer the position of the reference scale 11 is to the upper end or lower end of the peripheral surface 8, the smaller the color difference between the reference numerals 12 is drawn in a color.
  • This color setting makes the reference numerals 12 easier to see clearly as they move from the back to the front of the peripheral surface 8, improving the visibility of the reference numerals 12.

Furthermore, by positioning the end of the first pointer 21 opposite the current point 34 near the rotation axis C, it is possible to simulate a state in which the first pointer 21 is journaled on the rotation axis C, thereby enhancing the reality (sense of reality) of the first pointer 21 that is positioned outside the rotating cylinder 7.
