[0002] Control of a light projection of a means of transport

[0003] The present invention relates to a method, a computer program with instructions, and a device for controlling a light projection of a means of transportation. The invention also relates to a means of transportation that uses a method or device according to the invention.

[0004] Entertainment systems for motor vehicles are known which, for example, have screens or projection units on which films can be played or games can be displayed to entertain vehicle users. Motor vehicles with integrated projection units are also known. For example, DE 10 2021 116678 A1 describes a motor vehicle with a digital projection unit for projecting graphic or written information onto a projection surface. The digital projection unit is connected to a monitoring circuit of the motor vehicle in order to project the graphic or written information, evaluate an image recording of the graphic or written information, and change the projection of the graphic or written information onto the projection surface by the digital projection unit based on the evaluated image recording.

[0005] In addition, lighting devices for vehicle lighting systems that generate holograms in the vehicle's surroundings are also known. These holograms can achieve effects that go beyond the luminous function of conventional lighting devices: For example, warning functions can be created that, thanks to a three-dimensional impression, have a stronger impact on the viewer's perception than a conventional warning light, thus increasing safety.

[0006] DE 102016207 187 A1 describes a protective device for a motor vehicle for preventing wildlife from crossing a path located in front of the motor vehicle in an environment. The protective device comprises a light source and a projection device. The light source serves to generate a projection light in the motor vehicle. The projection device serves to generate a light projection from the motor vehicle into the environment using the projection light. The projection device is configured to visually present at least a graphic representation of an obstacle to a wild animal located in the environment, allowing it to move toward the path ahead, using the light projection.

[0007] US 2020 / 0290513 A1 describes a light field display system for augmenting a vehicle. The light field display system comprises light field display modules that form a surface of a vehicle. The light field display modules each have a display area and are arranged adjacent to one another to form a seamless display surface. This display surface has an effective display area that is larger than the display area. A viewer can interact with objects displayed in the effective display area.

[0008] It is an object of the invention to provide improved solutions for controlling a light projection of a means of transport for interaction with a user.

[0009] This object is achieved by a method having the features of claim 1, by a computer program with instructions according to claim 9, by a device having the features of claim 10, and by a means of transport according to claim 11. Preferred embodiments of the invention are the subject of the dependent claims.

[0010] According to a first aspect of the invention, a method for controlling a light projection of a means of transport comprises the steps:

[0011] - Projecting at least one virtual object into an environment of the means of transport;

[0012] - detecting a movement of a body part of a living being relative to the projected virtual object;

[0013] - Calculating a virtual energy or momentum transfer to the projected virtual object based on the detected motion; and

[0014] - Adjusting the projection of the virtual object according to the virtual energy or momentum transfer.

[0015] According to a further aspect of the invention, a computer program contains instructions which, when executed by a computer, cause the computer to perform the following steps for controlling a light projection of a means of transport:

[0016] - Projecting at least one virtual object into an environment of the means of transport; - Detecting a movement of a body part of a living being relative to the projected virtual object;

[0017] - Calculating a virtual energy or momentum transfer to the projected virtual object based on the detected motion; and

[0018] - Adjusting the projection of the virtual object according to the virtual energy or momentum transfer.

[0019] The term "computer" should be understood broadly. In particular, it also includes control units, embedded systems, and other processor-based data processing devices. The execution of the aforementioned steps can be performed directly by the computer or involve the computer controlling a component intended to execute a step, such as a projection unit or a sensor.

[0020] The computer program may, for example, be made available for electronic retrieval or stored on a computer-readable storage medium.

[0021] According to a further aspect of the invention, a device for controlling a light projection of a means of transport comprises:

[0022] - a projection module for projecting at least one virtual object into an environment of the means of transport;

[0023] - a detection module for detecting a movement of a body part of a living being relative to the projected virtual object; and

[0024] - a calculation module for calculating a virtual energy or momentum transfer to the projected virtual object based on the detected movement and for adjusting the projection of the virtual object according to the virtual energy or momentum transfer.

[0025] In the solution according to the invention, ambient lighting devices are used to generate light projections onto surfaces or holograms in the space surrounding a means of transport. People or animals can interact with these light projections or holograms via a virtual exchange of kinetic energy or a virtual momentum transfer, e.g. during a stopover. This enables improved entertainment or relaxation as well as support for sporting activities or training of people's motor skills or sense of balance in connection with vehicle use. Based on recognized real movement patterns of people or animals, virtual physical momentum and energy transfers to virtually represented objects in the space can be determined, e.g. using a trained artificial intelligence algorithm, which would physically occur in the same place during interactions with real objects.The projection of the virtual object is then adjusted according to the virtual energy or momentum transfer, ie the position and movement of the virtual object is changed as would be the case with a real object in the event of such an energy or momentum transfer.

[0026] According to one aspect of the invention, a virtual energy or momentum transfer to a virtual object can also be determined, which occurs indirectly via a real object used by the living being. For example, a virtual energy or momentum transfer can be determined that occurs from a real golf club used by the real person to a virtual projected golf ball. For this purpose, the movement pattern of the person or the golf club can be evaluated. The movement of the virtual golf ball is then executed accordingly and displayed to the user.

[0027] According to one aspect of the invention, an interaction between a virtual object and a living being occurs as soon as a minimum distance to a surface of the virtual object is exceeded. For example, a projected ball can move away from a dog due to a virtual energy or momentum transfer before contact with the surface of the virtually represented ball has been established.

[0028] According to one aspect of the invention, the virtual object is projected in two-dimensional or three-dimensional representation by at least one headlight or a holographic projector of the vehicle. A projector specifically designed for this purpose can be used to project virtual objects; however, modern headlights, such as laser headlights or matrix LED headlights (LED: Light Emitting Diode), can also be used, some of which already enable targeted light emission. Matrix LED technology is currently finding increasingly widespread use in motor vehicles, as an exterior lighting system featuring a matrix LED headlight is particularly powerful, especially with regard to adaptive lighting functions.If the corresponding matrix LED spotlight features a particularly high number of individual LEDs, a particularly high resolution of the objects projected onto the projection surface by the exterior lighting system is achieved. Furthermore, the electrical power required for projection is particularly low, so energy consumption is not significantly increased by the projection.

[0029] Additionally or alternatively, one or more lasers can be provided as the light source. This allows the luminous power density of the light projection to be set to a particularly high value. If required, digital imagers with imaging surfaces can also be used. For example, the digital imager can comprise an LCD display (LCD: liquid crystal display), an LED display, an OLED display (OLED: organic light-emitting diode) or a DMD imager (DMD: digital micromirror device). A DMD imager contains a DMD device in the form of an array of a large number of micromirrors that are moved via an actuator in order to deflect light beams in different directions and thereby generate image information.

[0030] According to the invention, the light radiation from one or more imagers can be split by means of an optical device such that one part of the light radiation serves only to generate a virtual object, and another part of the light radiation serves only to generate a light pattern or a homogeneous surface. The optical device thus enables separate treatment of the light radiation generated by the imager depending on whether a virtual object, a light pattern, or a homogeneous surface is being displayed. This allows different requirements to be easily taken into account when generating a virtual object, a light pattern, or a homogeneous surface.

[0031] According to one aspect of the invention, the movement of the body part of the living being relative to the projected virtual object is detected by means of an environmental sensor system of the means of transport. In the solution according to the invention, environmental sensors are used to detect the positions and movements of living beings in relation to the displayed virtual objects. Such environmental sensors are available in numerous vehicles today, in particular in autonomous or semi-autonomous vehicles. For example, an environmental camera system of a vehicle can be used, the images from which can be used for image processing and object recognition. In this case, movement patterns of people or animals can be detected and interpreted, e.g. with the aid of a trained artificial intelligence algorithm. According to one aspect of the invention, adapting the projection of the virtual object comprises a movement or deformation of the virtual object.The interaction between a living being and a virtual object occurs via virtual touches in such a way that the virtual object can be set in motion or decelerated according to the laws of physics, just as a corresponding real object would interact. For example, a projected soccer ball or a hologram of a soccer ball can be kicked or shot by a person with a kicking motion. Based on a recognized movement pattern of the person, a virtual momentum and virtual kinetic energy are transferred to the virtual ball, which then causes the virtual soccer ball to move like a real ball according to the laws of physics, possibly even deforming in the process.

[0032] According to one aspect of the invention, environmental parameters are taken into account when adapting the projection of the virtual object. When determining the virtual movement behavior of virtual objects, e.g., when determining a virtual trajectory of a virtual golf ball, available data on environmental parameters can be used, such as current local weather data, the slope of the local ground surface, or the local ground conditions. In this way, even more realistic movement or trajectories of the virtually displayed objects can be determined and shown to a vehicle user. Examples of weather data are wind strength, wind direction, or rain. The data can be determined using dedicated sensors or retrieved externally via a vehicle system.

[0033] According to one aspect of the invention, when the projection of the virtual object is adjusted, the virtual object's movement is slowed or accelerated. The virtual movements of the virtual objects can be presented to the user at a slower or faster speed than a physically correct movement. For example, the flight phase of virtual balls during juggling can be presented slower than in reality, making juggling easier for a human to learn. Likewise, the flight of a virtual baseball, thrown by a virtual baseball pitcher, for example, can be presented slower than in reality, giving the user more time to prepare for the virtual ball flying towards them.Through repetition, a real person can practice hitting a ball at the slower speeds of the virtually flying baseball, in order to then be able to hit it more effectively at physically accurate speeds. According to one aspect of the invention, additional information is conveyed to the living being using additional interaction systems. For example, the interaction between a person and a projected virtual object can be supported using augmented reality glasses. This allows, for example, additional virtual objects or information related to an activity to be displayed in the user's field of vision. For example, when juggling, a representation of the hand movements to be performed can be shown using augmented reality glasses.

[0034] Alternatively or additionally, haptic information can also be conveyed. For example, virtual impulses can be made tangible using smart clothing. For example, virtual ball contact during juggling can be made perceptible at precisely the right time using haptic actuators in smart gloves. For this purpose, the smart gloves preferably exchange data with a vehicle system. As another example, using an actuator in a smart golf club, the impact impulse upon impact with the virtual golf ball can be made tangible for the human, thus rendering the scene more realistic.

[0035] According to one aspect of the invention, the control of the light projection is subject to hazard monitoring. For example, using image processing and object recognition based on images from a vehicle camera system, it is possible to identify where people's faces or eyes are located or are likely to be located during further movement of the people. This allows the vehicle lighting system to adjust the lighting areas, if necessary in advance, so that people are not blinded by light projections or holograms.

[0036] Alternatively or additionally, environmental sensors and image analyses can be used to verify whether interactions with projected virtual objects can be carried out with sufficient probability in such a way that other people, animals, plants, or objects in the vicinity are not disturbed or damaged. A trained artificial intelligence algorithm can be used to assess the environment, for example, so that vehicle users can be warned if necessary before performing a desired interaction with a virtual object. This can prevent, for example, the backswing of a real golf club during a golf shot from damaging another vehicle.

[0037] Advantageously, a means of transport has a device according to the invention or is configured to carry out a method according to the invention for controlling a light projection. The means of transport can be a passenger car, in particular, but can also be a bus or a commercial vehicle. The means of transport can be configured to suggest locations that are particularly well suited to carrying out desired interactions with the aid of a vehicle system. For example, when guiding a route to a destination, a vehicle system can select intermediate stops in such a way that, for example, practicing hitting a golf ball can be carried out particularly well. Preferred procedures or interactions related to a vehicle user can be stored in a user profile.For example, during route guidance, intermediate stops can be suggested to a vehicle user in such a way that they can be linked to charging times for an electric vehicle, and in particular, charging points can be suggested where special interactions with projected virtual objects can be carried out particularly well.

[0049] To better understand the principles of the present invention, embodiments of the invention are explained in more detail below with reference to the figures. It is understood that the invention is not limited to these embodiments and that the described features may also be combined or modified without departing from the scope of the invention as defined in the appended claims.

[0050] Fig. 1 schematically shows a method for controlling a light projection of a means of transport. In a first step, at least one virtual object is projected 10 into the environment of the means of transport. The virtual object can be projected 10, for example, in a two-dimensional or three-dimensional representation by at least one spotlight or a holographic projector of the means of transport. In addition, a movement of a body part of a living being relative to the projected virtual object is detected 11, e.g., by means of an environmental sensor system of the means of transport. Based on the detected movement, a virtual energy or momentum transfer to the projected virtual object is calculated 12. The projection of the virtual object is then adjusted 13 according to the virtual energy or momentum transfer.This can, for example, include a movement or deformation of the virtual object, whereby environmental parameters can also be taken into account. If necessary, the virtual object's movement can be slowed down or accelerated when adjusting the projection. Additional information can also be conveyed using other interaction systems. The control of the light projection is preferably subject to hazard monitoring.

[0051] Fig. 2 shows a simplified schematic representation of a first embodiment of a device 20 for controlling a light projection of a means of transport. The device 20 has an input 21, via which, for example, data UD from an environment sensor system 43 of the means of transport can be received. A projection module 22 is configured to project at least one virtual object into an environment of the means of transport. For this purpose, the projection module 22 can output corresponding control signals S via an output 27 of the device 20 to a projection device of the means of transport, e.g., to a headlight 41 or a projector 42 for a two-dimensional or three-dimensional representation of the virtual object. A detection module 23 is configured to detect a movement of a body part of a living being relative to the projected virtual object, e.g., based on the data UD from the environment sensor system 43.A computing module 24 is configured to calculate a virtual energy or momentum transfer to the projected virtual object based on the detected movement and to adapt the projection of the virtual object according to the virtual energy or momentum transfer. For this purpose, the computing module 24 can forward the necessary information to the projection module 22. Adapting the projection can, for example, include a movement or deformation of the virtual object, whereby environmental parameters UP can also be taken into account. If necessary, a slowed or accelerated movement of the virtual object can occur when adapting the projection of the virtual object. Using further interaction systems 60, additional information can also be conveyed. For this purpose, corresponding control signals S can be output to the interaction systems 60 via the output 27.Preferably, the control of the light projection is subject to hazard monitoring.

[0052] The projection module 22, the acquisition module 23, and the computing module 24 can be controlled by a control module 25. Settings of the projection module 22, the acquisition module 23, the computing module 24, or the control module 25 can be changed via a user interface 28. The data generated in the device 20 can be stored in a memory 26 of the device 20 if necessary, for example, for later evaluation or for use by the components of the device 20. The projection module 22, the acquisition module 23, the computing module 24, and the control module 25 can be implemented as dedicated hardware, for example, as integrated circuits. Of course, they can also be partially or completely combined or implemented as software running on a suitable processor, for example, a CPU or a GPU.The input 21 and the output 27 can be implemented as separate interfaces or as a combined bidirectional interface. Fig. 3 shows a simplified schematic representation of a second embodiment of a device 30 for controlling a light projection of a means of transport. The device 30 has a processor 32 and a memory 31. For example, the device 30 is a computer, a control unit, or an embedded system. Instructions are stored in the memory 31 which, when executed by the processor 32, cause the device 30 to carry out the steps according to one of the described methods. The instructions stored in the memory 31 thus embody a program executable by the processor 32 which implements the method according to the invention. The device 30 has an input 33 for receiving data. Data generated by the processor 32 are provided via an output 34.In addition, data can be stored in memory 31. The input 33 and the output 34 can be combined to form a bidirectional interface.

[0053] The processor 32 may include one or more processor units, such as microprocessors, digital signal processors, or combinations thereof.

[0054] The memories 26, 31 of the described embodiments can have both volatile and non-volatile memory areas and can comprise a wide variety of storage devices and storage media, for example hard disks, optical storage media or semiconductor memories.

[0055] Fig. 4 schematically illustrates a means of transport 40 in which a solution according to the invention is implemented. In this example, the means of transport 40 is a motor vehicle. In the example shown, the motor vehicle has various projection devices. These are, on the one hand, the headlights 41, and on the other hand, a holographic projector 42. By means of an environmental sensor system 43, environmental data UD can be acquired. The environmental sensor system 43 can comprise, for example, cameras, radar sensors, lidar sensors, ultrasonic sensors, or climate sensors. The motor vehicle has a device 20 according to the invention for controlling a light projection. The device 20 can, for example, be implemented on a computer 44 of the motor vehicle. By means of a data transmission unit 45, a connection to a backend can be established, e.g.for transmitting settings, retrieving updated software for the components of the motor vehicle, or receiving environmental parameters UP. Environmental parameters UP can also be determined by the environmental sensors 43. A memory 46 is provided for storing data. Data exchange between the various components of the motor vehicle takes place via a network 47. Examples of interactions between living beings 51 and virtual objects 50 will be explained below using Fig. 5 to Fig. 11.

[0056] Fig. 5 schematically shows a first example of an interaction between a person 51 and a virtual soccer ball. A soccer ball is projected as a virtual object 50 onto the floor or into the room by a spotlight 41 of a means of transport 40 or by a projector not shown here. Interactions between people 51 and this soccer ball are detected by an environmental sensor system 43 of the means of transport 40. For this purpose, images from a camera of the environmental sensor system 43 can be analyzed, for example. The movements or interactions are evaluated with regard to a virtual energy or momentum transfer to the virtual object 50. The movements of the virtual soccer ball are then executed according to the interactions with the people 51. For example, the virtually projected soccer ball can be kicked back and forth between the two people 51 according to the detected shooting movements.The movement of the virtual football can be stopped by holding up a body part 52, e.g. a real foot, as with a real football.

[0057] Fig. 6 schematically shows a second example of an interaction between a person 51 and a virtual soccer ball. A soccer ball is projected onto the floor or into the room as a virtual object 50 by a spotlight 41 of a vehicle 40 or by a projector (not shown here). In addition, a goal wall with virtual openings is projected onto a wall. Only a portion of the light radiation from the spotlight 41 is used to generate the virtual object 50, while another portion of the light radiation is used to generate a light pattern 53. An environmental sensor system 43 of the vehicle 40 detects the interaction between the person 51 and the projected soccer ball. This enables virtual goal-wall shooting.

[0058] Fig. 7 schematically shows a first example of an interaction between a person 51 and a virtual golf ball. A target flag with a hole is projected as a first virtual object 50 by a spotlight 41 of a means of transport 40 or by a projector not shown here. The hole can be projected, for example, as a surface, and the target flag as a hologram. As a second virtual object 50, a golf ball is projected onto the floor or into the room as a hologram. The person 51 can interact with this golf ball using a real golf club. For this purpose, a virtual energy or momentum transfer is determined using an environmental sensor system 43 of the means of transport 40, which transfers from the real golf club used by the real person 51 to the virtual projected golf ball.

[0059] Fig. 8 schematically shows a second example of interaction between a person and a virtual golf ball. A spotlight 41 of a means of transport 40 or a projector (not shown here) projects a golf ball onto the floor or into the room as a hologram as a first virtual object 50. The person 51 can interact with this golf ball using a real golf club. For this purpose, an environmental sensor system 43 of the means of transport 40 determines a virtual energy or momentum transfer that occurs from the real golf club used by the real person 51 to the virtual projected golf ball. A representation of the golf ball's tee shot is projected onto a partial surface of a sphere, with a virtual trajectory of the virtual golf ball, as a second virtual object 50. The virtual trajectory is executed depending on the movement pattern of the golf club detected during the tee shot by the person 51.If available, current weather conditions can be taken into account when calculating the virtual trajectory of the virtual golf ball.

[0060] Fig. 9 schematically shows an interaction of a person 51 with virtual juggling balls. In this example, 50 balls are projected into the room as a hologram by a spotlight 41 of a means of transport 40 or by a projector (not shown here) as a virtual object. The person 51 can juggle these balls. An environmental sensor system 43 of the means of transport 40 detects the interaction of the person 51 with the projected balls, and the balls are moved accordingly. The flight phase of the virtual balls during juggling can be represented slower than in reality, making it easier for the person 51 to learn to juggle.

[0061] Fig. 10 schematically shows an interaction of a person 51 with a virtual baseball. In this example, a spotlight 41 of a means of transport 40 or a projector (not shown here) projects a baseball pitcher and a virtual baseball thrown by the pitcher into the room as virtual objects 50. The person 51 can hit this virtual baseball with a baseball bat. An environmental sensor system 43 of the means of transport 40 detects the interaction of the person 51 or the baseball bat with the virtual baseball, and the virtual baseball is moved accordingly. Here, too, the flight of the virtual baseball can be represented slower than reality, so that the person 51 has more time to prepare for the virtually approaching ball. Through repetition, the person 51 can thus practice a hit at slower speeds of the virtually flying baseball.

[0062] Fig. 11 schematically shows an interaction of an animal 51 with a virtual ball. The solution according to the invention is suitable not only for interaction with people but also for interaction with animals. In the example shown, a ball is projected onto the floor or into the room as a virtual object 50 by a spotlight 41 of a means of transport 40 or by a projector not shown here. Movements of the virtual ball are carried out in accordance with the movements of the animal 51 or the virtual contact detected by an environmental sensor 43 of the means of transport 40. An interaction between the animal 51 and the virtual object 50 can already take place if a minimum distance to the surface of the virtual object 50 is undershot, i.e. the virtual ball is already moving before contact occurs. In this way, for example, the animal can be prevented from attempting to bite the virtual object.
