Description

Field of the invention

The present invention relates to a method for optimizing the display on a display or multiple displays and / or the interaction with a display or a plurality of displays in a vehicle and an apparatus for carrying out the method.

Background of the invention

In the automotive industry, the use of flat screens or displays is now widespread, with the number of built in a vehicle displays has increased due to the increase in the information to be reproduced and the features to be used in recent years. Thus, on the displays of fully digital instrument cluster and arranged in the center console or other areas of the dashboard multifunction displays vehicle-relevant information such as speed, speed, remaining tank contents, mileage, warnings of malfunction but also, for example, image content for a navigation, assistance or infotainment system played. Various display technologies are used, such as TFT, LCD and AMOLED displays. Furthermore, it can be assumed that 3D displays, such as, for example, autostereoscopic displays, multi-layer displays or light field displays, will also be used in the future because visual information can then be displayed distributed in the space due to the perceived depth of the image.

The displays are usually permanently installed in the vehicle. However, it is also known, for example from the Audi MMI communication system, to drive a display out of the dashboard during operation of a vehicle and to let it disappear again in the dashboard when the vehicle is parked.

Also, the setting of vehicle parameters and the control of the above-mentioned systems have created new possibilities, such as the use of touch-sensitive flat screens. In the case of these so-called touch screen displays, an operation or control of a technical device can be carried out by tapping control elements shown on the display with one finger. The operation by means of a touchscreen display can be made significantly more versatile compared to mechanical controls such as buttons, switches, paddles or cogs, as shown for example on the touchscreen display controls can take any shape and be located anywhere within the displayed image content can. Furthermore, in addition to the tapping of the display surface, various other operating gestures can be used, such as a shift of the finger on the display surface or when using a multi-touch screen multi-finger gesture recognition, in which by simultaneously touching the display surface with multiple fingers, for example, the pulling apart of two Finger to zoom a picture content leads.

Despite, but partly due to, these developments in display technology, the ergonomic requirements placed on the displays are not always met. Thus, it is disturbing for a consistent display and operating concepts across all displays that due to the different installation positions of the displays, there are gaps in presentation between the displays. Also requires the steadily increasing number of information and functions to be displayed on the displays and possibly operated by these displays, new display and control concepts. After all, not every built in vehicle interior display is easy to reach from an ergonomic point of view.

Summary of the invention

It is an object of the invention to provide a user-friendly and ergonomic way of interacting with a display or multiple displays in a vehicle.

This object is achieved by a method having the features of claim 1 and by a corresponding device according to claim 11. Preferred embodiments of the invention are the subject of the dependent claims.

The inventive method for optimizing the display on a display or multiple displays and / or the interaction with a display or multiple displays in a vehicle is characterized in that the position of a display for adjusting the presentation and / or interaction is spatially changed.

This makes it possible to increase the ergonomics of the display and operation and to implement new display and operating concepts.

According to one embodiment of the invention, two displays are provided, wherein a displayed on a first display image object on a second display and can be displayed there and wherein at a transition of the image object from the first to the second display at least one of the two displays so electromechanically is moved, that the spatial distance between the two displays is reduced to each other.

This allows the smoothest possible transition of the passing image object and thus easy traceability. In particular, during the journey, the amount of information that can be received by the driver is limited, as this must concentrate on the driving task. A distraction of the driver as well as the gaze application time by searching the passed image object on the displays is thus minimized.

According to a development, at least one display is moved electromechanically perpendicular to the surface of the display. This is particularly advantageous if a plurality of displays are provided, which are structurally installed in the vehicle interior at different depths relative to each other.

According to an advantageous development of this embodiment of the invention, there are several depth levels for the image content to be displayed on the display, wherein the display is shifted in the direction of the depth levels.

In this development, the image content of a depth level can be displayed on the display depending on the spatial position of the display. When using a 2D display, depending on the depth position of this display, this makes it possible to selectively display a section of the overall picture content corresponding to the respective depth plane.

But it can also be an advantage that several depth levels are displayed simultaneously on the display. Thus, when using a 3D display already spatially arranged the user gets an overview of the entire image information.

A further development of the invention provides that it is possible to interact separately with the image content in the different depth planes, with the depth plane interacting with the spatial position of the display being interacted with.

This allows a particularly intuitive operation. Thus, on a 2D touch display lying in the current depth level image objects can be selectively touched and thus selected or operated by the physical movement of the display then before or behind the image objects are reached.

According to a further development, only a part of the image content lying in an image plane can be displayed for a specific position of the display and the display can be moved electromechanically parallel to this image plane to display another part of the image content lying in the same image plane. This can be advantageous in particular for extensive, two-dimensional representations such as map display in navigation applications.

Furthermore, the display can be tilted electromechanically, wherein different image contents are displayed as a function of the resulting rotation of the display.

In this case, it may be advantageous for the display to be tilted and / or displaced and / or deformed such that a region of the display that is far away from a user can be better reached.

The device according to the invention for optimizing the display of one or more displays and / or the interaction with a display or a plurality of displays in a vehicle has an image output unit which supplies image contents to at least one display and a control unit for controlling the image output unit and an electromechanical actuator is connected to the display and is supplied to the control unit, a control signal for mechanical position change in order to spatially change the position of the display for adjusting the representation and / or interaction.

An advantageous development of the device provides that in addition an evaluation unit for evaluating operator inputs is provided, which supplies the control unit with an operating signal.

Detailed description of the embodiments

For a better understanding of the principles of the present invention, embodiments of the invention will be explained in more detail below with reference to the figures. It should be understood that the invention is not limited to these embodiments, and that the features described may also be combined or modified without departing from the scope of the invention as defined in the claims.

1 schematically shows the sequence of a first method according to the invention for optimizing the representation and / or interaction with two adjacent in a vehicle arranged displays. According to process step 1 First, a representation of an image object on a serving as a source display first display device. In the process step 2 Now serving as a target display second display device is so electromechanically shifted that this is the source display spatially approximated. In the following process step 3 Now takes place a transition of the image object of the source display on the target display, for example, because due to a change of driving condition or usage behavior by the driver, the image object is only of secondary importance and a more distant display sufficient. The position of the target display is here spatially changed so that the transition of the image object from the source display to the target display appears as seamless as possible and is easy to understand for the driver. According to process step 4 then the target display is moved back to the original position.

The transition of the image object can take place automatically when a change in the driving state or the user behavior is detected by the user. Likewise, it is also conceivable that the image object is manually moved by the user from the source display to the target display, for example when the source display is required for display of other image contents or the target display is more suitable for displaying the image object. The transition can here be initiated by the user, for example by means of a swipe on a touchscreen display.

Instead of a picture object, several picture objects can also be transferred from the source display to the target display. The aforementioned image objects can be both a purely passive reproduction of information and graphically represented operating elements which, for example, when displayed on a touchscreen display with a finger, enable the operation or control of a technical device in the vehicle. Likewise, in addition to the passing image object on one or both of the displays, further image information and / or operating elements can be displayed which are anchored on the respective display and do not pass to the other display.

2 schematically shows the transition of an image object for this embodiment of the invention 7 from a source display 5 on a target display 6 , The arrangement of the two displays is shown from above, with the target display 6 from the driver's perspective further back. The picture object 7 This is initially on the source display 5 shown as shown in sub-figure 2a. After the destination display 6 as symbolized by the arrow, electromechanically shifted and spatially at the same height as the target display 5 was brought (part 2b), the picture object goes 7 from the source display 5 on the target display 6 over (subfigure 2c). Following this transition becomes the target display 6 again guided back to the original position, so that the representation of the image object on this display is now further in the background (sub-figure 2d).

Although in the above description, the transition of the image object between two adjacent 2D displays, the electromechanical shift of the target display for spatial approach to the source display can also be applied when one or both of the display device are designed as a 3D display. Likewise, it can be provided that both source and destination displays are both spatially displaced and move toward one another for the transition of the image object. Furthermore, the electromechanical displacement can be vertical, as in 2 shown, but also obliquely or even parallel to the surface of one of the displays.

3 schematically shows the sequence of a second inventive method for optimizing the representation and / or interaction with a display arranged in a vehicle. According to process step 1 Here, too, a representation of an image object or an interaction with an image object on a display device takes place. In the process step 2 Now the display device electromechanically displaced or tilted. This can be done for a variety of reasons. In this way, different image subregions of a representation scene can be represented or interactions can be designed in several stages. Likewise, a better visibility or accessibility of the display can thereby be achieved or the driver can be visually signaled in a change of the driving condition, for example, in the transition from an autonomous driving mode to a manual driving mode, that he now takes over the vehicle operation again. In the following process step 3 Now takes place from the shift or tilt resulting adjustment of the presentation and / or the interaction options. Thus, for example, in a first position main menu items and further position submenus can be displayed.

In 4 is schematically the displacement of a single display 5 shown. the display 5 In this case, it is preferable to move electromechanically perpendicular to the display surface. Depending on the position of the display 5 In this case, different interactions or representations are possible. Thus, according to a first embodiment, interactions can take place with different depth levels of a presentation scene. In the illustrated position of the display 5 becomes with the depth level 11 interacts, correspondingly, in a method of the display to the front with depth levels further forward and with a method of the display to the rear behind the depth level 11 located depth levels. In this case, the interaction can be effected in particular by means of a touch operation of the movable display, but also by means of mechanical operating elements arranged at another location, for example on a multifunction steering wheel, or by means of a voice input.

For interaction with different depth levels, the display can be automatically adjusted. It is also possible for the user to select the depth level that can be interacted with, for example by making the position to which the display is to be moved dependent on the strength of the finger pressure. Instead of adapting the interaction to different depth levels, the position change of the display can also be used to display different sections of an overall scene along the depth.

Furthermore, as a display, a 3D display, such as an autostereoscopic display can be used. In this case, independent of the spatial position of the display, several depth levels can then be displayed simultaneously. With the depth level 11 , which corresponds to the current spatial position of the display, then an interaction can take place.

Instead of the display 5 To move electromechanically perpendicular to the display surface, this can, as in 5 shown, also be moved parallel to the display surface. This allows for a larger representation of an overall scene lying in a plane 12 depending on the current spatial position of the display a partial section 13 display. Furthermore, instead of a change in position of the display perpendicular or parallel to the display surface, a rotation of the display also take place, as also in 5 indicated. Depending on the current rotation position, different contents can be made visible. Finally, it is also conceivable to make a deformation of the display by means of a plurality of electromechanical actuators in a flexible display.

Furthermore, moving, rotating, tilting or also deforming the display in the direction of the driver can make it possible to better reach areas of the display farther away from the driver. This is schematic in 6 shown, which is a part of a vehicle interior with a tilting display arranged in the region of the center console 5 shows. Under certain circumstances, graphical operating elements shown on the right of the display can be difficult to reach for the driver behind the steering wheel, but the accessibility of the display, which is indicated schematically in the direction of the driver, improves accessibility for the driver.

According to a further embodiment, it may be provided to determine whether the driver is looking at the display and, in this case, to tilt the display to him, since then an operation by the driver is to be expected. Thus, an additional eye-tracking sensor using a camera can automatically detect the driver's eyes and also capture the viewing direction. Accordingly, the display can be tilted to the front passenger when it is detected by the eye-tracking sensor that the passenger looks at the display and probably wants to make an operation.

7 shows a device for carrying out the method according to the invention. Depending on the embodiment, this can be a single display 5 or in addition another display 6 be provided.

A control unit 17 leads an image output unit 16 a control signal to cause this, the display 5 and optionally the further display 6 To supply image content. Depending on the computing power of the image output unit 16 stored finished graphics or else animations calculated in real time can be displayed here, for example if in the image output unit 16 a powerful graphics card is integrated.

Likewise controls the control unit 17 an electromechanical actuator 14 to change the position of the display 5 at. The electromechanical actuator is so with the display 5 connected, that he can move or tilt this depending on the embodiment and can for example consist of an electric motor, wherein the rotational movement of the electric motor is converted into a translational movement.

Operational inputs of the driver or passenger, in this embodiment by means of a touch-sensitive surface of the display 5 be made in an evaluation unit 15 evaluated for the operator inputs. Optionally, on the display 5 also a pressure or force sensor for detecting a on the surface of the display 5 be applied pressure provided. The evaluation unit 15 leads the control unit 17 an operating signal corresponding to the operating inputs, which then a control signal for adapting the displayed image contents to the image output unit 16 and / or a signal for mechanical change of position to the actuator 14 outputs.

Finally, the control unit 17 an information 18 about the current driving condition, for example, from a transmission control unit, and / or the current usage behavior or the current operating behavior of the driver, for example, from an eye-tracking sensor, supplied to possibly also in dependence on an adjustment of the displayed image content and / or mechanical change in position make.

The control unit 17 can consist of a single electronic control unit that usually includes one or more input and output stages, an interface for data communication and a microcontroller, which in turn usually consists of a processor core, one or more memory chips for the software and a working memory. Likewise, the invention can be implemented by means of a plurality of control devices, which then communicate via suitable interfaces.
