Description

[0001] The approach presented here relates to a method and a control unit for controlling an output of display data on a display unit of a device and to a device having a display unit and a control unit according to the main claims.

[0002] Conventional representations on displays or displays of devices with a vertical viewing or viewing option by a user of the device are known.

[0003] The approach presented here aims to provide an improved method and an improved control unit for controlling an output of display data on a display unit of a device, as well as an improved device with a display unit and a control unit.

[0004] According to the approach presented here, this problem is solved by a method for controlling the output of display data on a display unit of a device and a device having a display unit and a control unit with the steps and features of the main claims. Advantageous embodiments and further developments of the approach presented here emerge from the following subclaims.

[0005] A method for controlling the output of display data on a display unit of a device comprises a step of reading position data into an evaluation unit of the device. The position data represents a user's position relative to the device. The method also comprises a step of generating an output image. The output image corresponds to at least one display content / display symbol distorted using the position data. The method further comprises a step of controlling the output of the output image as display data on the display unit.

[0006] Position data can be understood as data that represents a user's position in relation to the device. The position data can therefore provide information about the user's location in relation to the device. For example, the position data can be captured by a camera that can detect the current position of the device user. The position data is read in by an evaluation unit. An evaluation unit can be understood here as a unit that reads in and evaluates the position data. The generated output image can be understood as an image that corresponds to a display symbol that has been distorted using the position data.The display symbol can be a symbol such as a character, a symbol, a number or at least a letter, which is displayed or can be displayed on the display unit as a single display symbol or multiple display symbols in the form of the output image or in the form of the display data. Display data can therefore be understood here as data in the form of the display symbol or display symbols or in the form of the output image that is or can be displayed on the display unit. A display unit can be understood to be a unit on which the display data, i.e. the output image, can be displayed. For this purpose, the display unit can be designed in particular as a display.

[0007] The approach presented here is based on the realization that by optimizing or improving the user's view of the display unit from different perspectives, an optimal or improved representation of the content to be displayed on or via the display unit can be advantageously achieved. The user can thus quickly and easily recognize the information of the underlying display symbol through the output image to be displayed.

[0008] The approach presented here is advantageous in that the display unit, also referred to as display content, display, display area, display area, display content or display, can be read without any significant influence even when viewed 'obliquely from the side' onto the display unit, ideally as if the view were perpendicular to the display unit.

[0009] According to one embodiment, in the step of reading in position data, a user's viewing angle of the display unit relative to a normal to the display unit can be read in. This offers the advantage that, when controlling the output of the output image as display data on the display unit, the user's viewing angle of the display unit relative to a normal to the display unit can be advantageously taken into account in order to make the control of the output even more precise and efficient, so that the user can view the display unit conveniently and comfortably.

[0010] According to a further embodiment, in the generation step, a width and / or a height of the display symbol can be changed depending on the viewing angle in order to obtain the output image. This offers the advantage that, when generating the output image, the user's viewing angle of the display unit relative to a normal to the display unit can advantageously be taken into account in order to make the generation of the output image even more precise and efficient with respect to the user's position, so that the output can advantageously be controlled with the generated output image.

[0011] According to a further embodiment, in the reading step, the position data can be read in as the position of an identified individual user. In the generating step, the output image can be generated using the identified individual user. For example, a user's height can be taken into account by also adjusting the height of the display image. This is advantageous in that the display symbol can be distorted using the position of the identified individual user in order to adequately generate the output image for the identified individual user according to their individual needs with regard to the display unit and to thereby differentiate it from any other users of the device whose individual needs with regard to controlling the display unit might be different from those of the user.

[0012] According to a further embodiment, the generation of the output image can be suppressed in the generation step if at least one other user is detected in front of the device. This is advantageous in that a decision can be made individually for each potential user as to whether or not the output image should be generated. It can also prevent irritation to other users who see a distorted and difficult-to-read display in the display image. Accordingly, this allows for individual differentiation between the individual users, depending on which user the device detects before the latter.

[0013] The approach presented here further creates a control unit configured to execute, control, or implement the steps of a variant of the method presented here in corresponding units. This embodiment of the approach presented in the form of a control unit also allows the task underlying the approach presented to be solved quickly and efficiently.

[0014] The control unit can be configured to read input signals and, using the input signals, to determine and provide output signals. An input signal can, for example, represent a sensor signal that can be read in via an input interface of the control unit. An output signal can represent a control signal or a data signal that can be provided at an output interface of the control unit. The control unit can be configured to determine the output signals using a processing instruction implemented in hardware or software. For example, the control unit can comprise a logic circuit, an integrated circuit, or a software module and, for example, be implemented as a discrete component or be comprised of a discrete component.

[0015] Furthermore, a device with a display unit and a control unit is presented. This variant of the described approach, in the form of a device with a display unit and a control unit, also allows the task underlying the described approach to be solved quickly and efficiently.

[0016] Also advantageous is a computer program product or computer program with program code that can be stored on a machine-readable carrier or storage medium such as a semiconductor memory, a hard disk memory, or an optical memory. If the program product or program is executed on a computer or a control unit, the program product or program can be used to carry out, implement, and / or control the steps of the method according to one of the embodiments described here.

[0017] Although the approach described is based on a household appliance, the approach described here can be used accordingly in the context of a commercial or professional appliance.

[0024] A generation unit 200 generates an output image 205. The output image 205 corresponds, for example, to a Fig. 1 described position data generated display symbol 210. In this Fig. 2, a fish is shown as an example as display symbol 210. In some cases, but in this Fig. 2, the generating unit 200 changes a width and / or a height of the display symbol 210 depending on the following in Fig. 7 in order to obtain the output image 205.

Optionally, the generation unit 200 suppresses the generation of the output image 205 if the device 100 detects another user in front of the device 100. If the two previously mentioned users (or multiple users) are in a similar position relative to the device (e.g., at a similar angle to the device), an adjustment of the output image may also be useful or take place in this case.

[0025] A control unit 215 controls an output of the output image 205 as display data on the display unit 115 in order to display the output image 205 generated by the generation unit 200 on the display unit 115.

This Fig. 3 illustrates the above-mentioned Fig. 1 shown view from the perspective of the normal 120 to the display unit 115, as it is in Fig. 1 user sees or would see from his perspective there as an example.

[0028] The generation unit 200 generates the output image 205. The output image 205 corresponds, for example, to several using the above-mentioned Fig. 1 described position data generated display symbols 210. In this Fig. 3, numbers and letters are shown as display symbols 210. In some cases, but in this Fig. 3 not explicitly shown, the generating unit 200 changes a width and / or a height of the display symbols 210 depending on the following in Fig. 7 in order to obtain the output image 205. Optionally, the generation unit 200 generates the output image 205 using the method described above in Fig. 1 described identified individual user.

For example only, the device 100 is the device shown in Fig. 1 and / or Fig. 2 and / or Fig. 3 is used as an oven. The user stands diagonally or sideways in front of the device 100 and looks from there in the direction of the device and the display unit 115. The user, also called the viewer, is therefore not in any position directly in front of the device 100.

[0032] The evaluation unit 105 of the device 100 reads the position data 110. Optionally, the evaluation unit 105 reads the position data 110 as the position of the Fig. 1 described identified individual user. The position data 110 represents the position of the user as described in this Fig. 4 shown as an example diagonally or laterally in front of the device 100.

[0035] The generation unit 200 generates the output image 205. The output image 205 corresponds, for example, to the one obtained using the method described above in Fig. 4 described position data generated display symbol 210. In this Fig. 5, a fish is shown as an example as display symbol 210. In some cases, but in this Fig. 5, the generating unit 200 changes the width and / or the height of the display symbol 210 depending on the following in Fig. 7 in order to obtain the output image 205.

[0036] The control unit 215 controls the output of the output image 205 as display data on the display unit 115 in order to display the output image 205 generated by the generation unit 200 on the display unit 115. This allows the display symbol 210, which is shaped as a fish, to be displayed on the display unit 115.

[0037] In other words, this Fig. 5 a content of the display unit 115, which the Fig. 4. In other words, this Fig. 5 a representation of the display unit 115 which results for the viewer.

[0038] Fig. Figure 6 shows a schematic representation of a device 100 according to an embodiment. For example only, the device 100 is the oven shown in one of the figures described above. Fig. 6 illustrates the Fig. 4 or a similar perspective of the user obliquely or sideways onto the display unit 115, from where the Fig. 4, the user is looking or would look in the direction of the display unit 115. This perspective of the user on the display unit 115 is therefore not from a position directly in front of the device 100.

[0039] The generation unit 200 generates the output image 205. The output image 205 corresponds, for example, to several using the above-mentioned Fig. 4 described position data generated display symbols 210. In this Fig. 6, numbers and letters are shown as display symbols 210. In some cases, but in this Fig. 6 not explicitly shown, the generating unit 200 changes the width and / or the height of the display symbol 210 depending on the following in Fig. 7 in order to obtain the output image 205. Optionally, the generation unit 200 generates the output image 205 using the method described above in Fig. 1 described identified individual user. Optionally, the generation unit 200 suppresses the generation of the output image 205 if the device 100 detects another user in front of the device 100.

[0040] The control unit 215 controls the output of the output image 205 as display data on the display unit 115 in order to display the output image 205 generated by the generation unit 200 on the display unit 115. This allows the display symbols 210, which are exemplified as numbers and letters, to be displayed on the display unit 115.

[0041] In other words, this Fig. 6 a content of the display unit 115, which the Fig. 4. In other words, this Fig. 6 a representation of the display unit 115 which results for the viewer.

[0042] Fig. Figure 7 shows a schematic representation of a device 100 according to an embodiment. For example only, the device 100 is the oven shown in one of the figures described above. The user stands diagonally or sideways in front of the device 100 and looks from there in the direction of the device and the display unit 115. The user, also called the viewer, is therefore not in any position directly in front of the device 100.

[0043] The evaluation unit 105 of the device 100 reads the position data 110. Optionally, the evaluation unit 105 reads the position data 110 as the position of the Fig. 1 described identified individual user. The position data 110 represents the position of the user as described in this Fig. 7 shown as an example, diagonally or laterally in front of the device 100. Optionally, the evaluation unit 105 reads in as position data 110 a viewing angle α of the user on the display unit 115 with respect to the normal 120 on the display unit 115. The display unit 115 is arranged, for example, on the front 125 of the device 100, for example on the device panel. The user is standing, for example, as in this Fig. 7, at a position outside the normal 120, i.e. in particular obliquely or laterally in front of the device 100.

[0044] In other words, this Fig. 7 shows a vertical view of a scene in which a user is standing laterally offset in front of the device 100 and is viewing its display unit 115. The relative user position in front of the device 100 is known to the device 100, for example, through the use of suitable sensors or technology. In other words, this Fig. 7 a representation in which the position of the viewer is known to the device 100, for example by means of UWB (ultrawideband), ToF, lidar, camera or the like.

[0045] Fig. Figure 8 shows a schematic representation of a device 100 according to an embodiment. For example only, the device 100 is the oven shown in one of the preceding figures. Fig. 8 illustrates the Fig. 7 or a similar perspective of the user obliquely or sideways onto the display unit 115, from where the Fig. 7, the user is looking or would look in the direction of the display unit 115. This perspective of the user on the display unit 115 is therefore not from a position directly in front of the device 100.

[0046] The generation unit 200 generates the output image 205. The output image 205 corresponds, for example, to the one obtained using the method described above in Fig. 7 distorted display symbol 210. In this Fig. 8, a fish is shown as an example as a display symbol 210. The generation unit 200 changes the width and height of the display symbol 210 depending on the Fig. 7 in order to obtain the output image 205. In particular, the display symbol 210 is distorted, thus providing the user with an advantageous way of viewing the output image 205. This allows the user to view the output image 205 in a manner similar to that of standing directly in front of the device 100, as described above, for example, in Fig. 1 shown and described.

[0047] Optionally, the generation unit 200 generates the output image 205 using the method described above in Fig. 1 described identified individual user. Optionally, the generation unit 200 suppresses the generation of the output image 205 if the device 100 detects another user in front of the device 100.

[0048] The control unit 215 controls the output of the output image 205 as display data on the display unit 115 in order to display the output image 205 generated by the generation unit 200 on the display unit 115. This allows the display symbol 210, which is shaped as a fish, to be displayed on the display unit 115.

[0049] In other words, this Fig. 8 a corrected, i.e. distorted, content of the display unit 115, which the Fig. 7. Depending on the user's position, the content of the display unit 115 has been perspectively corrected, i.e. distorted. In other words, this Fig. 8 a representation of the display unit 115 corrected, i.e. distorted, depending on the user position, which results for the viewer.

[0050] The Fig. In other words, Figure 8 describes a correction, i.e. distortion, of the representation of the display unit 115, by way of example, with the actual viewing angle conditions resulting for the user.

[0051] If, for example, a respective position of the user relative to the device 100 is known through the use of a corresponding technology on the device, such as UWB (Ultra-Wideband), camera-based systems, ToF (Time of Flight) or the like, the content of the display unit 115 can be perspectively ‘converted’ or corrected, i.e. distorted, depending on the viewing angle of the person viewing the device 100.

[0052] By correcting, i.e. distorting, the perspective, the viewer is presented with a representation that optimally corresponds as closely as possible to a familiar image, i.e. a familiar perspective, when viewed vertically from the display unit 115.

[0053] If it is further known which user is in front of the device 100, the content to be displayed on the display unit 115 can be individually adapted.

[0054] The display correction, i.e. the display distortion, could either be automatically deactivated and / or manually switched on or off when several people use the device 100 at the same time.

[0055] Fig. Figure 9 shows a schematic representation of a device 100 according to an embodiment. For example only, the device 100 is the oven shown in one of the preceding figures. Fig. 9 illustrates the Fig. 7 or a similar perspective of the user obliquely or sideways onto the display unit 115, from where the Fig. 7, the user is looking or would look in the direction of the display unit 115. This perspective of the user on the display unit 115 is therefore not from a position directly in front of the device 100.

[0056] The generation unit 200 generates the output image 205. The output image 205 corresponds, for example, to the images generated using the Fig. 7 described position data distorted display symbols 210. In this Fig. 9, numbers and letters are shown as display symbols 210. The generation unit 200 changes the width and height of the display symbols 210 depending on the Fig. 7 in order to obtain the output image 205. In particular, the display symbols 210 are distorted, thus providing the user with an advantageous way of viewing the output image 205. This allows the user to view the output image 205 in a manner similar to that of standing directly in front of the device 100, as described above, for example, in Fig. 1 shown and described.

[0057] Optionally, the generation unit 200 generates the output image 205 using the method described above in Fig. 1 described identified individual user. Optionally, the generation unit 200 suppresses the generation of the output image 205 if the device 100 detects another user in front of the device 100.

[0058] The control unit 215 controls the output of the output image 205 as display data on the display unit 115 in order to display the output image 205 generated by the generation unit 200 on the display unit 115. This allows the display symbols 210, which are exemplified as numbers and letters, to be displayed on the display unit 115.

[0059] In other words, this Fig. 9 a corrected, i.e. distorted, content of the display unit 115, which the Fig. 7. Depending on the user's position, the content of the display unit 115 has been perspectively corrected, i.e. distorted. In other words, this Fig. 9 a representation of the display unit 115 corrected, i.e. distorted, depending on the user position, which results for the viewer.

[0060] The Fig. In other words, Figure 9 describes a correction, i.e. distortion, of the representation of the display unit 115, by way of example, with the actual viewing angle conditions resulting for the user.

[0061] Fig. Figure 10 shows a schematic representation of a device 100 according to an embodiment. By way of example only, the device 100 is the oven shown in one of the preceding figures. Fig. Figure 10 illustrates a view from the perspective of the normal 120 to the display unit 115, as shown in Fig. 1 shown user sees or would see from his point of view there, but with the distorted display symbol 210, as described above in Fig. 8 is described in more detail.

[0062] The generation unit 200 generates the output image 205. The output image 205 corresponds, for example, to the one obtained using the method described above in Fig. 7 distorted display symbol 210. In this Fig. 10 shows an example of a fish as a display symbol 210. The generation unit 200 changes the width and height of the display symbol 210 depending on the Fig. 7 in order to obtain the output image 205. In particular, the display symbol 210 is distorted, so that the user has an advantageous opportunity to view the output image 205 when he is at the Fig. 7 described in more detail. In this Fig. 10, however, the view from the perspective of the normal 120 to the display unit 115 is shown, as it is in Fig. 1 shown user sees or would see from his perspective there. Therefore, the display symbol 210 in the Fig. 10, the actual representation of the display unit 115 from the perspective of the normal 120 to the display unit 115 would be distorted if the user were to look at the display unit 115 from this perspective.

[0063] Optionally, the generation unit 200 generates the output image 205 using the method described above in Fig. 1 described identified individual user. Optionally, the generation unit 200 suppresses the generation of the output image 205 if the device 100 detects another user in front of the device 100.

[0064] The control unit 215 controls the output of the output image 205 as display data on the display unit 115 in order to display the output image 205 generated by the generation unit 200 on the display unit 115. This allows the display symbol 210, which is shaped as a fish, to be displayed on the display unit 115.

[0065] In other words, this Fig. 10 a perspectively corrected, i.e. distorted, content of the display unit 115 of the Fig. 7 depicted scene, which the Fig. 1 shown viewer (standing directly in front of the device 100) would see (distorted representation). In other words, this Fig. 10 an actual representation of the display unit 115.

[0066] Fig. Figure 11 shows a schematic representation of a device 100 according to an embodiment. By way of example only, the device 100 is the oven shown in one of the preceding figures. Fig. 11 illustrates a view from the perspective of the normal 120 to the display unit 115, as shown in Fig. 1 shown user sees or would see from his point of view there, but with the distorted display symbols 210, as described above in Fig. 9 is described in more detail.

[0067] The generation unit 200 generates the output image 205. The output image 205 corresponds, for example, to the images generated using the Fig. 7 described position data distorted display symbols 210. In this Fig. 11, numbers and letters are shown as display symbols 210. The generation unit 200 changes the width and height of the display symbols 210 depending on the Fig. 7 in order to obtain the output image 205. In particular, the display symbols 210 are distorted, so that the user has an advantageous possibility of viewing the output image 205 when he is at the Fig. 7 described in more detail. In this Fig. 11, however, the view from the perspective of the normal 120 to the display unit 115 is shown, as it is in Fig. 1 shown user sees or would see from his perspective there. Therefore, the display symbols 210 in the Fig. 11, the actual representation of the display unit 115 from the perspective of the normal 120 to the display unit 115 would be distorted if the user were to look at the display unit 115 from this perspective.

[0068] Optionally, the generation unit 200 generates the output image 205 using the method described above in Fig. 1 described identified individual user. Optionally, the generation unit 200 suppresses the generation of the output image 205 if the device 100 detects another user in front of the device 100.

[0069] The control unit 215 controls the output of the output image 205 as display data on the display unit 115 in order to display the output image 205 generated by the generation unit 200 on the display unit 115. This allows the display symbols 210, which are exemplified as numbers and letters, to be displayed on the display unit 115.

[0070] In other words, this Fig. 11 a perspectively corrected, i.e. distorted, content of the display unit 115 of the Fig. 7 depicted scene, which the Fig. 1 shown viewer (standing directly in front of the device 100) would see (distorted representation). In other words, this Fig. 11 an actual representation of the display unit 115.

[0071] Fig. 12 shows an embodiment of a flowchart of a method 1200 for controlling the output of display data on a display unit of a device. The method 1200 comprises a step 1205 of reading position data into an evaluation unit of the device. The position data represents a position of a user of the device. The method 1200 also comprises a step 1210 of generating an output image. The output image corresponds to at least one display symbol distorted using the position data. The method 1200 further comprises a step 1215 of controlling the output of the output image as display data on the display unit.

[0072] Fig.13 shows a schematic representation of a control unit 1300 according to an embodiment. The control unit 1300 comprises the evaluation unit 105 for reading position data. The position data represents a position of a user of the device. The control unit 1300 also comprises the generation unit 200 for generating an output image. The output image corresponds to at least one display symbol distorted using the position data. The control unit 1300 further comprises the control unit 215 for controlling the output of the output image as display data on the display unit 115.

[0073] According to one embodiment, the approach presented here can alternatively be referred to as perspective adaptation of display representations depending on the user position.

[0074] The presented approach is applicable, for example, to devices that use a display. It doesn't matter whether the display is installed vertically (e.g., oven), at an angle (e.g., washing machine), or horizontally (e.g., hob).
