Abstract
Description
[0001] The invention relates to a method for displaying a three-dimensional hologram above a motor vehicle according to the preamble of patent claim 1. The invention also relates to a computer program product.
[0002] German patent application DE 10 2006 050 546 A1 discloses a method for displaying information, in which at least one projection object is generated at a projection location outside a motor vehicle. The projection object is three-dimensional and generated by holographic projection. German patent application DE 10 2014 114 049 A1 discloses a device and a method for activating a function of a vehicle, comprising a holographic device for generating a holographic display visible to a user. The holographic display can be generated above the vehicle upon appropriate operation of an ID transmitter by the user, making it easier to locate the vehicle.American Patent Application US 2018 / 0229643 A1 discloses a vehicle information device with a projector unit configured to display vehicle conditions in the form of a hologram projected through the exterior of the vehicle. American Patent Application US 2019 / 0196212 A1 discloses a vehicle-mounted device comprising a projector configured to project the three-dimensional image based on data from a three-dimensional image in the air above the vehicle. International Patent Application WO 2020 / 163801 A1 discloses a computer-implemented method for configuring interactive media adapted for passengers temporarily sharing a common means of transport.
[0003] The object of the invention is to functionally improve the operation of a motor vehicle.
[0004] This problem is solved by a method having the features of patent claim 1. The claimed method provides, among other advantages, that the three-dimensional hologram can not only be used to display information, but, in combination with the communication function, enables a highly effective contactless exchange of information. This provides the possibility of contactless communication from inside the motor vehicle with the surroundings or outside world via the communication function using the three-dimensional hologram.
[0005] A preferred embodiment of the method is characterized in that the three-dimensional hologram for representing the communication function is displayed above a vehicle roof of the motor vehicle. A corresponding communication interface projects a desired object or text above the vehicle. This easily ensures that the desired object and / or text is clearly visible and thus easily perceptible in the surroundings of the motor vehicle, especially even at a greater distance.
[0006] Another preferred embodiment of the method is characterized in that the three-dimensional hologram is used to signal a ride-sharing opportunity. Using suitable symbols, optionally combined with a number, it is thus possible to very efficiently indicate whether a ride is available in the motor vehicle. The number can then advantageously also be used to indicate how many people can be transported in the motor vehicle.
[0007] A further preferred embodiment of the method is characterized in that the three-dimensional hologram is used to visualize the occupancy of the motor vehicle. This information can be used, for example, in the context of the previously described signaling of a ride-sharing opportunity. However, the visualization of the occupancy of the motor vehicle can also be used for other useful purposes.
[0008] A further preferred embodiment of the method is characterized in that the three-dimensional hologram is used to visualize the emotional state of at least one occupant, in particular a driver, of the motor vehicle. This information can be used in the surroundings of the motor vehicle to draw conclusions about the driver's expected driving behavior. Depending on the application, the three-dimensional hologram can also advantageously be used directly to visualize an expected driving behavior. For example, a suitable hologram can be used to indicate a sporty or leisurely driving style.
[0009] A further preferred embodiment of the method is characterized in that the three-dimensional hologram is used to display a dating function. For example, the dating function can be used to communicate a relationship status of a passenger of the motor vehicle, in particular a driver of the motor vehicle, with the aid of the three-dimensional hologram.
[0010] Another preferred embodiment of the method is characterized in that the three-dimensional hologram is used for advertising placement. This can, for example, make advertising for a company more efficient in company vehicles. However, even in private vehicles, better-placed advertising with the help of the three-dimensional hologram can generate additional revenue streams. For example, the three-dimensional hologram placed above the vehicle can be used to advertise a regional event.
[0011] The invention further relates to a computer program product having at least one non-volatile computer-readable storage medium on which computer-readable program instructions are stored, wherein the computer-readable program instructions comprise program instructions designed to carry out a previously described method. The function of the hologram projector can be controlled via PCM or an app. The capital letters PCM stand for remote control or radio remote control with digital signals. The abbreviation PCM stands for Pulse Code Modulation. The "app" stands for the term "application" or "use". This specifically refers to application software in the field of mobile operating systems.
[0012] The invention may also relate to a motor vehicle with a display device as described above.
[0013] Further advantages, features, and details of the invention will become apparent from the following description, in which various embodiments are described in detail with reference to the drawings. They show: Fig. 1 a perspective view of a motor vehicle with a vehicle roof in which a hologram projector is integrated to display a three-dimensional hologram above the vehicle roof, and the Fig. 2 to 4 similar representations as in Fig. 1 with different holograms.
[0014] In the Fig. 1 to 4 each show a perspective view of a motor vehicle 1 with a vehicle roof 2. A hologram projector 3 is integrated into the vehicle roof 2. The hologram projector 3 is arranged at a central location in the middle of the vehicle roof 2. The central location of the vehicle roof 2 is preferably the highest point of the motor vehicle 1.
[0015] In the Fig. 1 to 4, the hologram projector 3 is designed in different sizes and is more or less conspicuously integrated into the vehicle roof 2. In Fig. 1, the hologram projector 3 is relatively well visible. In Fig. 4, the hologram projector 3 is so well integrated into the vehicle roof 2 that it is no longer visible from the outside.
[0016] With the hologram projector 3, three-dimensional holograms 5 can be generated above the vehicle roof 2, which are clearly visible from the surroundings of the motor vehicle 1.
[0017] In Fig. 1, the three-dimensional hologram 5 is shown in simplified form as a two-dimensional rectangle 11. In Fig. 2, the three-dimensional hologram 5 is shown in simplified form as a two-dimensional speech bubble 12. In Fig. 3, the three-dimensional hologram 5 is shown simplified as a two-dimensional star 13. In Fig. 4, the three-dimensional hologram 5 is shown as a three-dimensional arrow 14.
[0018] The hologram projector 3 is used in the vehicle roof 2 to display a device 4 for displaying the three-dimensional hologram 5 above the vehicle roof 2. The three-dimensional hologram 5 is advantageously used to display at least one communication function with the motor vehicle.
[0019] In the Fig. 1 and Fig. Figure 2 illustrates, by means of the rectangle 11 and the speech bubble 12, how the three-dimensional hologram 5 can be used for communication with the outside world. Communication from the motor vehicle 1 to a person outside the motor vehicle 1 is possible, as is communication between a person inside the motor vehicle 1 and a person outside the motor vehicle 1. Via a suitable communication interface, an object and / or text to be communicated is displayed in the rectangle 11 or in the speech bubble 12 above the roof 2 of the motor vehicle 1.
[0020] Various applications are possible for this. For example, the outside world can be informed that a ride is available in motor vehicle 1. A destination can be displayed using the three-dimensional hologram 5. Alternatively or additionally, a planned route can be displayed using the three-dimensional hologram 5.
[0021] In taxis, the three-dimensional hologram 5 can be used to indicate whether a taxi is occupied or free. For this purpose, the three-dimensional hologram 5 can be used to display a suitable symbol above the roof 2 of the motor vehicle 1.
[0022] The Star 13 in Fig. Figure 3 shows an example of such a symbol. The option of a message displayed using the communication function in the three-dimensional hologram 5 is not limited to one application area. Another example is the implementation of a dating function using the three-dimensional hologram 5.
[0023] Within the dating function, a user group can be defined, for example, among drivers of a specific vehicle brand. Alternatively or additionally, the dating function can be advantageously linked to an app.
[0024] Alternatively or additionally, the three-dimensional hologram 5 can be used to place advertising above the roof 2 of the motor vehicle 1. The three-dimensional hologram 5 makes it easy to display advertising clearly visible above and in combination with the motor vehicle 1.
[0025] For advertising purposes, for example, a paid partnership can be entered into with buyers or owners of motor vehicle 1 to place a desired advertisement across a wide area, for example, in cities. The display of the three-dimensional hologram 5 is particularly advantageous both when the motor vehicle 1 is stationary and when it is moving.
[0026] The arrow 14 in Fig. 4 can be used, for example, in a motor vehicle sales area to indicate a specific motor vehicle 1 that is for sale. Alternatively or additionally, arrows as shown in Fig. 4, a series of a variety of motor vehicles can be visualized that might be of interest to a specific buyer.
[0027] Another practical way in which the three-dimensional hologram 5 above the vehicle roof 2 can be used is for video displays. For example, while the vehicle 1 is stationary, it is possible to display films. This makes it possible to create an open-air cinema directly on the vehicle 1.
