Description

Technical field

[0001] The present invention relates to a computer-implemented method and system for configuring at least two display devices arranged close to each other for wireless communication, wherein these are connected to and / or assigned to a central processing unit. A computing unit configured to execute the computer-implemented method can be coupled to or integrated into a central processing unit. Technical background

[0002] When a computer or an image-generating device with an integrated display (e.g., a notebook) is operated together with one or more peripheral devices, especially display devices (e.g., monitor / display / screen, television), and / or, for example, with multiple speakers, the position of the respective displays relative to each other must first be manually determined after the (initial) connection.

[0003] The same procedure is also necessary if the computer / calculator or the image-generating device itself does not have an integrated display, but several displays / speakers are to be used with this computer / calculator / etc.

[0004] This manual configuration of the positions of display devices arranged as close as possible to each other within range of wireless communication (preferably short-range communication) is necessary to enable intuitive use of pointing devices such as a pointing device (e.g. computer mouse) and the seamless display of screen content across multiple displays.

[0005] However, if the physical position of the display devices relative to each other changes (e.g., by adjusting the height of a monitor) or if display devices are added / removed, the arrangement of all displays usually has to be manually reconfigured.

[0006] The object of the present invention is to provide a method, a computer program product, a computer-readable storage medium and a technical system by means of which display devices can be configured in an improved manner.

[0007] This task is solved by independent claims. Advantageous further training is the subject of dependent claims. Summary of the invention

[0008] One aspect of the invention relates to a computer-implemented method for automatically configuring a display setting of at least two display devices arranged close to each other for short-range communication and assigned to and / or connected with a central unit, wherein a computing unit coupled to or integrated into the central unit is designed to perform the following steps: a) Depending on the number of first radio components (C1A, C1B) assigned to the central unit and the number of second radio components (D1A, D1B) assigned to a display unit (D1) of said display units, signals are exchanged between the first and second radio components on radio transmission links in every combination, wherein the number of first radio components and the number of second radio components is each at least two, b) Determining the relative position of at least two display devices to each other by evaluating signal transmission times and / or signal arrival angles of the exchanged signals; c) Determining / setting setting values ​​to configure the display setting based on the determined relative position; and d) Executing the configuration of the display settings based on the specified setting values.

[0009] In other words, in the context of a display device and a central unit, at least four signal transmission time-of-flight values ​​or signal angles of arrival are determined or evaluated by the at least two radio components assigned to a display device and at least two radio components assigned to the central unit, and the relative position is calculated from these.

[0010] This procedure can be applied analogously to one or more second display devices. Typically, eight or a multiple of four signal transmission time-of-flight values ​​or signal arrival angles are determined when additional display devices with two radio components are added and two radio components are assigned to the central unit.

[0011] If an additional radio component is assigned to the central unit, meaning at least three radio components, then six signal transmission time-of-flight values ​​or signal angles are determined. In addition to the four signal transmission time-of-flight values ​​or signal angles mentioned above, two further signal transmission time-of-flight values ​​or signal angles originate from the additional radio component. Typically, twelve or a multiple of six signal transmission time-of-flight values ​​or signal angles are determined if additional display units with two radio components are added and three radio components are assigned to the central unit.

[0012] The two closely spaced displays can comprise two separate displays, with the first display connected to the central processing unit (CPU) and the second display integrated into the CPU, as is common in laptops. It is also possible for two displays to be connected to the CPU, and for the CPU to have no display of its own, as is common in desktop PCs. Alternatively, a CPU with its own display can be connected to two closely spaced displays.

[0013] In this context, "assignment of the radio component" means that the radio component may be integrated into the display device or central unit, attached to the display device or central unit, or a combination thereof. Furthermore, "assignment of the display device" in this context means that the display device is connected to the central unit via cable or wirelessly, or that the display device is integrated into the central unit.

[0014] By assigning the first radio components to the central unit, their position in the spatial environment is known, although their absolute position does not need to be known.

[0015] The number of first radio components can be four, and the number of second radio components can be three, to determine their relative positions and orientations to each other. Without assumptions about how the display devices are arranged, oriented, tilted, or rotated, the number of radio components as specified above is necessary. Assumptions can be made that the display devices are, for example, perpendicular to the desk or horizontally / vertically oriented and roughly in the same plane. The display surfaces can be oriented horizontally or vertically (landscape / portrait) to the plane of, for example, a surface.

[0016] The number of first radio components is less than four and the number of second radio components is less than three if assumptions and / or information about the arrangement of the display devices on a plane and / or the horizontal and / or vertical orientation of the individual display devices and / or the parallel and perpendicular arrangement of the edges of the display surfaces to each other and / or geometric properties are given. Geometric properties such as the length of the display surface diagonal or other dimensions of the display device may be known.

[0017] In a special case of a previously assumed arrangement of the display devices on one level, the number of second radio components is at least one instead of at least two.

[0018] A central processing unit (CPU) can be a notebook, a VR or AR headset (VR = Virtual Reality, AR = Augmented Reality), or any other (mobile) device that connects to a display. A CPU can integrate a processing unit, which may contain one or more processors. The CPU and processing unit can be connected / coupled either wired or wirelessly.

[0019] The invention automatically performs the virtual positioning of the display device, optionally using acoustic devices. This is done according to the physical positioning of the display device and its dimensions. The invention utilizes a radio technology that enables the most accurate possible time-of-flight measurement for position determination. For the resulting location measurement or position determination, the precise position(s) of the radio component(s), e.g., antenna position(s), on the display device (relative to the screen area) can be assigned to a central unit (e.g., a notebook) with a processing unit. The processing unit can comprise one or more processors and be integrated into a notebook, as well as be equipped with a control unit or controller.

[0020] Furthermore, it should also be known which (wired or wireless) image output channel of the computer (e.g., USB-C connection for image transmission) supplies the display device. Information that cannot always be derived from these location measurements can, if necessary, be provided in other ways (screen dimensions, monitor orientation - horizontal or vertical).

[0021] The signal time-of-flight measurement described above is generally based on the fact that electromagnetic or acoustic waves propagate at a finite, known speed. If a signal is sent, for example, from a radio component assigned to the central processing unit (CPU) to a measurement object, such as a radio component on an external display device, from which it is reflected, and the time it takes for the round trip is measured, the object distance can be calculated from the time of flight and the propagation speed of the signal (group velocity of the wave) (see https: / / de.wikipedia.org / wiki / Entfernungsmessung#Triangulation). Several methods exist for calculating distances to multiple anchor points, such as the antennas on the display devices and a radio component of the CPU (see, for example, https: / / de.wikipedia.org / wiki / Entfernungsmessung#Triangulation). The distance is usually determined by trilateration or triangulation.To determine the position of an unknown point in three-dimensional space, four known points are required; on a surface / plane, three known points are sufficient; and along a trajectory, two known points are sufficient.

[0022] One embodiment of the invention can therefore provide that, in the case of a previously assumed arrangement of the display devices on one plane, the number of second radio components is only at least one instead of at least two.

[0023] The configuration of the display devices primarily concerns activating and / or deactivating display devices and / or establishing a connection with new display devices and / or settings with regard to the relative virtual arrangement of the display devices and / or settings with regard to an arrangement of applications and / or application icons for a home screen (start screen on the display or VR or AR glasses) of the central unit.

[0024] For example, UWB indoor localization (as known from Apple AirTags) can be used here. UWB stands for "Ultra-Wideband" radio technology, which utilizes a very high frequency spectrum and enables very precise localization (currently accurate to within a few centimeters). The signal pulses or (response) signals of the aforementioned wireless communication technology are preferably based on UWB (Ultra-Wideband).

[0025] UWB is a wireless communication technology (https: / / l-mobile.com / industrie-40 / uwbtechnologie-zur-indoor-positionsbestimmung-und-ortung / ) that operates on a very wide bandwidth of radio frequencies (ultra-wideband). UWB tracking offers the advantage of high accuracy and reliability, even in environments with many obstacles or interference.

[0026] Based on measured signal propagation times and known coordinates of fixed anchor / reference points in a spatial environment, an algorithm can calculate the distances between the tag and the anchor points. These distances are then used to determine the tag's position within the spatial environment. By calculating distances to multiple anchor points, the UWB tag's position relative to the anchor arrangement can be precisely determined.

[0027] In addition to the calculation methods TDoA (Time Difference of Arrival) and PDoA (Phase Difference of Arrival) as well as Angle of Arrival (AoA), Twoway Ranging (TWR) is used in this context (https: / / kinexon.com / de / products / uwb-technology).

[0028] With regard to the invention, the relative distances / positions to each other are relevant. Various radio components on / in the central unit (e.g., on the notebook display) can be defined as anchors, but their absolute position need not be known.

[0029] Alternatively, any other suitable localization technology can be used. RFID transponders (e.g., NFC), Bluetooth tags, Zigbee, or other short-range communication technologies can be employed, in which case distances can be calculated via triangulation, trilateration, or a combination thereof.

[0030] The signal transmitted by a second wireless component can contain a unique identifier for the respective wireless component of the associated peripheral device (display device). This identifier allows identification of the display device itself (in addition to its position on the display device) and, ideally, also of the corresponding image output channel (e.g., the correct USB-C connection) on the central processing unit. This unique identification of the display device also enables its assignment to the image output channel on the central processing unit and, if applicable, to other properties of the display device (display type, display size, native resolution, integrated peripherals, current display orientation, etc.).

[0031] From the calculated relative position and the identifier, a logic regarding the relative virtual arrangement of the display devices can be recognized, and the configuration can be adjusted based on this logic.

[0032] Preferably, the relative position determined in step b) remains unchanged if inaccuracies in the determined signal transit time values ​​or signal incidence angles remain within a specified deviation.

[0033] An applied heuristic can enable the alignment of the display devices with one of their edges if inaccuracies in position determination remain within a specified deviation or limit(s).

[0034] The configuration of display devices can involve enabling and / or disabling display / capture / acoustic output devices, establishing a connection with new display / capture / acoustic output devices, and / or configuring settings regarding the relative arrangement of such devices, as well as screen resolution settings. Additionally, it can also be possible to select the integrated devices (for example, which camera or speaker should be active) based on their arrangement or specific relative position.

[0035] The configuration can be managed centrally using an administration system or the computing unit, depending on an event and depending on a rule table.

[0036] A method for managing a group of devices with at least two devices using a management system has already been proposed in DE 10 2023 207 569.5. After configuration, the processing units of the individual notebooks wait for trigger events or environmental conditions stored in a rule table, such as disconnecting or connecting the notebook to a specific screen, a predetermined time, the use of a specific program and / or functionality, the detection of a specific person, or other events. Depending on the event or environmental condition that has occurred, for example, screen disconnected versus screen connected, the processing unit disconnects or establishes the notebook, including the Bluetooth connection to peripheral devices such as a mouse and keyboard, according to the stored rules.

[0037] Manual, time-consuming, and error-prone configuration is eliminated every time the physical arrangement or device composition changes and is replaced by precise, automatic virtual positioning. This method can be used for any number of display devices. Different types of display devices are possible. These can be connected to the computer or other signal source via wired or wireless connections.

[0038] Another aspect of the invention is a technical system for carrying out the above method, wherein the technical system comprises the central unit.

[0039] The facility(ies), system or device(s) and any associated unit(s) are designed to perform such process steps and may be implemented in hardware, firmware and / or software.

[0040] Another aspect of the invention is a computer program (product) comprising a program code executable by a computing unit or processor, or several program code modules executable and interacting by several computing units, which includes instructions that cause the execution of the method according to one of the above-mentioned embodiments.

[0041] The computer program or product can be stored on a computer-readable storage medium or data carrier. It is possible that the computer program (product) is embedded in a data carrier signal intended for downloading it from a server to a storage medium. The computer program or product can be written in a common programming language (e.g., C++, Java). A processing unit or processor for executing its program code / program code modules can comprise a standard computer or server with appropriate input, output, and storage capabilities. This processing unit or computing unit can be integrated into the control unit or system, or into its components.

[0042] The computer-implemented process also applies to so-called cloud services (cloud = computer cloud). A computer cloud typically comprises one or more servers operated by a cloud service provider and configured to deliver a cloud service to a service provider, e.g., a consortium of factories. Therefore, the system can be implemented in a computer cloud.

[0043] The technical equipment / devices or the technical system as well as the computer program (product) and computer-readable media or data carriers or data carrier signals can be further developed or trained analogously to the above-mentioned procedure and its further developments.

[0044] The technical system or computer program (product) can be further developed analogously to the embodiments of the above-mentioned method.

[0045] Further advantages, details and developments of the invention will become apparent from the following description of exemplary embodiments in conjunction with the drawings. Fig. Figure 1 shows a possible positioning of antennas using UWB as an example. Fig. Figure 2 shows a flowchart for the process according to the invention, and Fig. Figure 3 shows an embodiment of the invention in which the peripheral devices are selected automatically.

[0046] In the example, shown in Fig. Figure 1 shows two peripheral devices, for example, display devices or screens D1 and D2, each of which may also integrate a webcam and / or speakers, and a central unit in the form of a notebook C, which includes a processing unit with at least one processor. These peripheral devices are positioned close to each other for wireless communication and can be connected / coupled wirelessly. Certain devices or components can also be connected via wired connections, such as the notebook to the screens / displays / monitors via HDMI or to speakers via an optical cable connection.

[0047] UWB radio components, for example in the form of antennas D1A, D1B, and D2A, D2B of a display device, are attached to two diagonally opposite corners of the display areas involved. By measuring the signal propagation time or signal angle between the different points (e.g., D1A top left and D1B bottom right of display D1, and C1A top left and C1B bottom right of notebook C), the relative position of the display areas can be determined. More precisely, the signal propagation times or signal angles between all participating transmit / receive units or radio components on all display devices are determined. Using D1A and D1B on display device D1 and D2A and D2B on display device D2, the propagation times of the signals between D1A-D2A, D1A-D2B, D1B-D2A, and D1B-D2B are therefore measured. However, there can also be more display devices and multiple radio components on a single display device.

[0048] If the radio components have been retrofitted, it is also advisable to measure the travel time / distance between D1A and D1B.

[0049] An example of a technical system according to the invention consists of a central unit or a control unit and, for each connected screen, at least two (UWB) radio components (integrated into or attached to the screen). A central controller is generally integrated into the central unit, but can also be retrofitted into the central unit and coupled to it. Each radio component preferably has a unique identifier, which is also used to encode where the antenna is located (e.g., even identifier top left, odd identifier bottom right).

[0050] Alternatively, such information (and other information such as the current orientation, display dimensions, etc.) can also be transmitted or looked up in other ways (e.g., the wired / wireless connection for data transmission, the messages transmitted for location tracking, or by looking it up in a database).

[0051] The central controller consists of at least two radio components. As shown in the flowchart of the Fig. As shown in Figure 2, in steps a and b, active signal pulses are sent to the wireless components of the displays. The wireless components of the displays react immediately to the reception by sending a response signal, which typically contains a unique identifier for the UWB wireless component of the display. This identifier allows identification of the specific display itself (in addition to its position on the screen) and, ideally, also the corresponding image output channel (e.g., the correct USB-C connection). The central controller receives the response signals and can determine the relative position of the wireless components to each other (for example, via the time-of-flight differences in step c). This yields the position and, if applicable, the orientation of the physical display areas of the display devices relative to each other.

[0052] To determine not only whether the screen / display is to the left or right of the notebook (or another display), but also the horizontal / vertical distance or offset (and possibly relative alignment), several highly accurate distance measurements are typically taken between antennas at various positions on the devices involved (for example, top left and bottom right). If, despite measurement inaccuracies, the relative position determination, based on predefined constraints, indicates a likely alignment of the display devices with one of the edges (horizontal / vertical), a heuristic can ensure that a precisely aligned virtual positioning of the display devices occurs. This avoids minor deviations and enables precise configuration despite measurement inaccuracies.

[0053] To ensure that the virtual positioning remains stable, limits are set for fluctuations in the position determination, within which no change in the virtual positioning occurs.

[0054] The location measurements taken should be attributable to the device (e.g., display or notebook) and the exact antenna position on the device (relative to the screen area). Furthermore, it should also be known which (wired or wireless) image output channel of the computer (e.g., USB-C connection for image transmission) supplies the display device. Information that cannot always be derived from these location measurements will be provided by other means (screen dimensions, screen orientation – horizontal or vertical). Once the virtual position of the screens has been determined according to their physical positions, setting values ​​for configuring the display settings can be determined based on the established relative position (step d), and finally (in step e) the display settings can be configured using these determined values.Such configurations can involve enabling and / or disabling display devices, establishing connections with new display devices, and / or adjusting settings regarding the relative virtual arrangement of display devices, and / or adjusting settings regarding the arrangement of applications and / or application icons for a home screen (arrangement of display elements on a so-called home screen) of the central unit. The configuration can also include the selection of peripheral devices (e.g., camera, speakers, etc.) and, if applicable, screen resolution, volume settings, brightness settings, etc. Initial system configuration:

[0055] If radio signals from previously unknown radio components (of a new screen) are detected during the communication described above, an assignment between radio components and screen (including the associated output channel) may need to take place via user interaction.

[0056] Depending on the circumstances (integrated wireless components versus retrofitted wireless components), two variants are supported: Option 1 (Fully automated configuration with integrated radio modules): An automatic assignment is made between wireless components and the screen connected via a display channel. If the wireless components are integral parts of the screen, this is possible, for example, by including identifiers for the wireless components in the signals they transmit, allowing the system to deduce the screen's identifier (e.g., the serial number of the USB-C device). Subsequently, further required information (screen diagonal / geometry, resolution, orientation, etc.) can be obtained by communicating with the device or by looking up the screen type in a corresponding database.

[0057] Additionally, this information can also be transmitted, for example, via the channel used for image / data transmission or for time-of-flight measurement.

[0058] If an assignment is not possible, variant 2 can also be used here.

[0059] Variant 2 (configuration for retrofitted / installed radio components): Newly discovered wireless components are displayed to the user via a suitable dialog that lists the connected display devices and allows for intuitive assignment of the new wireless components to the newly added screen. Due to the potential time correlation between the discovery of the wireless components and the detection / connection of a new screen, a preselection can be made, or the default selection can be automated.

[0060] In particular, one embodiment of the invention would be illustrated in Fig.3. It is possible to automatically select the peripheral devices integrated into the screens or the central processing unit (such as speakers LL1, LR1, LL2, LR2, LRC, LLC, webcams IW, AW, microphones) and the peripheral devices actually used during operation. Examples include automatically selecting webcam AW, which is positioned as close as possible to the center of all screens, or using the outer (left) speaker LL1 of the first (left) screen D1 and the outer (right) speaker LR2 of the second (right) screen D2. For this to work, the assignment of peripheral devices to their respective screens should be known or determined through a user interaction.

[0061] Although the invention has been illustrated and described in detail by the preferred embodiment, the invention is not limited by the disclosed examples and other variations can be derived from them by the person skilled in the art.

[0062] The implementation of the processes or procedures / steps described above can be carried out using commands or instructions stored on computer-readable, non-volatile storage media or in volatile computer memory (hereinafter collectively referred to as computer-readable memory). Examples of computer-readable memory include volatile memory such as caches, buffers, or RAM, as well as non-volatile memory such as removable media, hard drives, etc.

[0063] The functions or steps described above can be represented in the form of at least one instruction set in / on computer-readable memory. These functions or steps are not bound to a specific instruction set, a specific form of instruction sets, a specific storage medium, a specific processor, or specific execution schemes, and can be executed by software, firmware, microcode, hardware, processors, integrated circuits, etc., either independently or in any combination. Various processing strategies can be employed, such as serial processing by a single processor, multiprocessing, multitasking, or parallel processing, etc.

[0064] The instructions can be stored in local storage, but it is also possible to store the instructions on a remote system, e.g., the cloud, and access them via a network.

[0065] In the context of the invention, "computer-based" or "computer-implemented" can, for example, be understood to mean an implementation of the method in which, in particular, a processor or a computing unit, which may be part of the technical system or control device or the (control or processing) device or unit and / or a computer and / or one or more services in a computer cloud of a service provider, performs at least one process step of the method.

[0066] Unless otherwise specified in the following description, the terms "map", "recreate", "receive", "apply", "output", "provide" and the like preferably refer to actions and / or processes and / or processing steps that modify and / or generate data and / or convert the data into other data, wherein the data may in particular be represented or exist as physical quantities.

[0067] The terms "processor," "central signal processing," "control unit," or "data processing device," as used herein, encompass processing devices in the broadest sense, including, for example, servers, general-purpose processors, graphics processors, digital signal processors, application-specific integrated circuits (ASICs), programmable logic circuits such as FPGAs, discrete analog or digital circuits, and any combination thereof, including all other processing devices known to those skilled in the art or which may be developed in the future.
