Description

[Technical Field]

[0001] The present invention relates to a projection device that projects and displays information relating to operations on a control panel provided at an elevator hall or inside an elevator car. [Background technology]

[0002] Conventionally, for example, Patent Document 1 proposes a contactless operation button switch for an elevator car control panel. Also proposed is a control panel that allows special operation inputs by long-pressing or multiple presses of a button, or by flick input. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-156181 Summary of the Invention [Problem to be solved by the invention]

[0004] When the operation inputs to the control panel become complicated as described above, it becomes necessary to explain how to operate the panel to the user. Also, there is the problem that it is difficult to tell at a glance whether the door is open or closed just from the simple image on the button, as in the case of the door open button and the door close button.

[0005] For example, attaching instructions near the buttons on a control panel reduces the design of the panel. Also, if numbers or icons are displayed on the button surfaces to avoid reducing the design, problems arise, such as fingers overlapping the buttons during operation, making it difficult to see the display on the button surfaces.

[0006] An object of one aspect of the present invention is to provide a projection device that can present information to users without detracting from the design of an elevator control panel. [Means for solving the problem]

[0007] In order to solve the above problems, the projection device according to aspect 1 of the present invention is a projection device that projects and displays information related to operations on a control panel installed at an elevator landing or inside the car, and includes an object detection unit that detects a target object present in a space within a predetermined range from the control panel, and a projection unit that projects predetermined information onto the surface of the target object detected by the object detection unit.

[0008] According to the above configuration, for example, the hand of a user attempting to operate the control panel is detected as a target object by the object detection unit, and predetermined information is projected and displayed on the surface of the hand. Therefore, there is no need to display information on the control panel, etc., and information can be presented to the user without compromising the design of the control panel. Furthermore, because the information is displayed on the hand attempting to operate the control panel, it is easier for the user to notice the displayed information.

[0009] A projection device according to a second aspect of the present invention may be configured in the above-mentioned first aspect such that the object detection unit detects the target object by at least one of a distance sensor, a photoelectric sensor, and image recognition using a captured image.

[0010] According to the above configuration, it is possible to accurately detect a target object that exists in a space within a predetermined range from the operation panel.

[0011] A projection device according to aspect 3 of the present invention may be configured in accordance with aspect 1 or 2 above, further comprising a projection control unit that controls the information projected by the projection unit, wherein the object detection unit detects the detection position of the detected target object, and the projection control unit controls the projection unit to project information according to the detection position.

[0012] According to the above configuration, it is possible to change the information to be projected depending on, for example, the button that the user is about to operate.

[0013] A projection device according to aspect 4 of the present invention may be configured in accordance with aspect 1 or 2 above, further comprising a projection control unit that controls the information projected by the projection unit, and a state detection unit that detects an operation input state on the operation panel, and the projection control unit may be configured to control the projection unit to project information according to the operation input state.

[0014] According to the above configuration, it is possible to change the information to be projected depending on the state of operation input being performed on the operation panel.

[0015] A projection device according to aspect 5 of the present invention may be configured in the above-mentioned aspect 4 such that the state detection unit detects the elapsed time or the number of operation inputs since an operation input was made to the operation panel, and the projection control unit controls the projection unit to project information corresponding to the elapsed time or the number of operation inputs.

[0016] According to the above configuration, it is possible to change the information to be projected in accordance with the time elapsed since an operation input was made or the number of operation inputs.

[0017] A projection device according to aspect 6 of the present invention may be configured such that, in any of aspects 1 to 5 above, the projection unit stops projection when the object detection unit detects the target object continuously for a predetermined time or more, or when the size of the target object detected by the object detection unit is equal to or larger than a predetermined value.

[0018] According to the above configuration, if a target object is detected continuously for a predetermined time or longer, it is highly likely that the target object is not an object attempting to operate the control panel, and therefore unnecessary projection can be stopped. Also, if the size of the detected target object is equal to or larger than a predetermined value, it is highly likely that the target object is not an object attempting to operate the control panel, and therefore unnecessary projection can be stopped.

[0019] An operation system according to a seventh aspect of the present invention includes the projection device according to any one of the first to sixth aspects and the operation panel. [Effects of the Invention]

[0020] According to one aspect of the present invention, information can be presented to users without degrading the design of the elevator control panel. [Brief explanation of the drawings]

[0022] [Embodiment 1] An embodiment of the present invention will be described in detail below. FIG. 1 is a diagram showing an outline of an example of operation of an elevator system 100A according to this embodiment. As shown in FIG. 1, when a user operates an operation panel 10A, the elevator system 100A projects predetermined information (e.g., store information for the destination floor of the button being operated) onto the surface of a target object O, such as the user's finger or the back of the hand, using a projection unit 22. This makes it possible to present various types of information to the user. The elevator system 100A will be described in detail below.

[0023] (Configuration of elevator system 100A) Fig. 2 is a block diagram showing the configuration of the main parts of the elevator system 100A. As shown in Fig. 2, the elevator system 100A includes a car 1 in which a user boards, an operation panel 10A, an elevator control unit 2, and a projection device 20A.

[0024] The control panel 10A receives operation inputs from elevator users. FIG. 3 is a schematic diagram of the area around the control panel 10A inside the car 1. As shown in FIGS. 1 and 3, the control panel 10A is provided inside the car 1. As shown in FIGS. 1 to 3, the control panel 10A has a plurality of buttons 11.

[0025] Button 11 accepts an operation input when pressed by an object such as a user's finger. In this embodiment, operation panel 10A is described as including, as buttons 11, a plurality of buttons for accepting input of destination floors, a button for accepting an instruction to open the doors of car 1, and a button for accepting an instruction to close the doors of car 1, but elevator system 100A in this embodiment is not limited to this. Operation panel 10A outputs the detection result of pressing of button 11 to elevator control unit 2 and projection device 20A.

[0026] The elevator control unit 2 controls the operation of each unit of the elevator system 100A. For example, the elevator control unit 2 raises and lowers the car 1 based on the detection result of the pressure output from the operation panel 10A.

[0027] The projection device 20A projects and displays information relating to operations performed by a user on the operation panel 10A. The projection device 20A includes an object detection unit 21A, a projection unit 22, and a control unit 30A.

[0028] The object detection unit 21A detects a target object O present in a space within a predetermined range from the operation panel 10A. The object detection unit 21A in this embodiment is configured with a distance sensor. The object detection unit 21 may detect a target object O present at a predetermined distance from the operation panel 10A in a normal direction of the operation panel 10A, for example, using a TOF (Time Of Flight) method. The object detection unit 21A may be provided at a position where it can detect a target object O present in a space within a predetermined range from the operation panel 10A. For example, as shown in FIG. 3, the object detection unit 21 may be installed on the ceiling of the car 1. Alternatively, the object detection unit 21 may be installed on a side of the car 1 between the ceiling of the car 1 and the operation panel 10A. Since the object detection unit 21A is configured with a distance sensor, it can accurately detect a target object O present in a space within a predetermined range from the operation panel 10A. In addition, the object detection unit 21 detects the detection position of the detected target object O.

[0029] Projection unit 22 projects predetermined information onto the surface of target object O detected by object detection unit 21A. In other words, projection unit 22 projects an image indicating predetermined information onto the surface of target object O detected by object detection unit 21A. Projection unit 22 may be, for example, a projector, and may project the information onto the surface of target object O by irradiating light.

[0030] The control unit 30A controls the operation of each unit of the projection device 20A. The control unit 30A includes a projection control unit 31A.

[0031] The projection control unit 31A controls the information projected by the projection unit 22 (in other words, the image projected by the projection unit 22). The projection control unit 31A may control the projection unit 22 to project information according to the detection position of the target object O detected by the object detection unit 21A. As shown in FIG. 2, the operation panel 10A and the projection device 20A configure an operation system 50.

[0032] Furthermore, the projection control unit 31A may project predetermined information onto the surface of the target object O detected by the object detection unit 21A, in accordance with the detection result of the pressing of the button 11 received from the operation panel 10A.

[0033] An example of information projection by the projection device 20A in the elevator system 100A will be described below with reference to FIGS.

[0034] (Projection example 1) In Projection Example 1, an example in which the object detection unit 21A detects the back of a user's hand as the target object O near a button on the control panel 10A indicating the destination floor of the third floor will be described with reference to FIG. 4 . FIG. 4 is a diagram illustrating an example of an image projected onto the target object O in Projection Example 1. In Projection Example 1, the projection control unit 31A controls the projection unit 22 so that the information projected onto the back of the user's hand by the projection unit 22 is an image indicating that the button the user is about to press is the third floor, as indicated by reference numeral 401 in FIG. 4 . This allows the user to confirm that the destination floor of the button the user is about to press is the third floor from the information projected onto the back of the hand, even if the indication indicating the destination floor displayed on the button surface becomes difficult to see due to the user's finger or the like. Alternatively, the projection control unit 31A may control the information projected by the projection unit so that an image indicating the characters "third floor," which is the destination floor of the button the user is about to press, and information about stores located on the third floor, is projected onto the back of the user's hand, as indicated by reference numerals 402 and 403 in FIG. 4 . This allows the user to confirm from the information projected onto the back of the hand that the destination floor of the button the user is about to press is the third floor, and to confirm the information of the store set for the third floor. Here, although the information of the store set for the third floor can be displayed on the operation panel 10A, displaying it on the operation panel 10A would detract from the design of the operation panel 10A. In contrast, when the information is displayed by the projection unit 22, there is no need to display the information on the operation panel 10A, and therefore the information can be presented to the user without detracting from the design of the operation panel 10A.

[0035] In the above example, the target object O is described as the back of the user's hand, but the target object O is not limited to the back of the user's hand, and may be, for example, the user's finger, the user's arm, etc.

[0036] (Projection example 2) Projection Example 2 is based on the premise that elevator system 100A is configured such that, when button 11 for receiving input of a destination floor is pressed, pressing button 11 twice cancels the input instruction for that button 11. In this case, an example will be described with reference to FIG. 5 in which control unit 30A of projection device 20A receives from operation panel 10A information that button 11 for receiving input of a destination floor has been pressed, and then object detection unit 21A detects the back of a user's hand as target object O near button 11. FIG. 5 is a diagram illustrating an example of an image projected onto target object O in Projection Example 2. In Projection Example 2, projection control unit 31A controls information projected onto the back of the user's hand by projection unit 22, as shown in FIG. 5, so that information indicating that the input instruction can be canceled by pressing the button twice can be displayed. This allows the user to be informed that the input indicating the destination floor can be canceled by pressing the button twice.

[0037] (Projection example 3) In Projection Example 3, an example in which the object detection unit 21A detects the back of a user's hand as the target object O near a button that accepts an instruction to open the door of car 1 will be described with reference to FIG. 6. FIG. 6 is a diagram showing an example of an image projected onto the target object O in Projection Example 3. In Projection Example 3, the projection control unit 31A controls the projection unit 22 so that the information projected onto the back of the user's hand by the projection unit 22 displays an animation showing the door opening, as shown in FIG. 6. Specifically, the projection control unit 31A controls the projection unit 22 so that the animation showing the door opening is displayed by circulating images 601, 602, 603, and 604 shown in FIG. 6 in this order. This allows the user to confirm from the information projected onto the back of the hand that the button they are about to press is the button that accepts an instruction to open the door of car 1, even if the display displayed on the surface of the button is difficult to see due to their own finger or the like.

[0038] (Projection example 4) In Projection Example 4, an example will be described in which the image (information) projected by the projection unit 22 is the same image (hereinafter also referred to as a fixed image) regardless of the detection position of the target object O. In this case, when the object detection unit 21A detects the target object O present in the space within a predetermined range from the operation panel 10A, the projection unit 22 projects the fixed image onto the surface of the target object O. Therefore, in Projection Example 4, the projection device 20A does not need to include the control unit 30A. FIG. 7 is a diagram showing an example of an image projected onto the target object O in Projection Example 4. In this example, the operation panel 10A accepts user operation input in a non-contact manner as in Embodiment 4 described later. In this case, when the object detection unit 21A detects the target object O present in the space within a predetermined range from the operation panel 10A, the projection unit 22 projects an image indicating that operation input is possible onto the target object O using a non-contact sensor, as shown in FIG. 7. This allows the user to confirm that operation input is possible using the non-contact sensor.

[0039] As described above, the projection device 20A in this embodiment includes an object detection unit 21A that detects a target object O present in a space within a predetermined range from the operation panel 10A, and a projection unit 22 that projects predetermined information onto the surface of the target object O, as shown in projection examples 1 to 4.

[0040] According to the above configuration, for example, the hand of a user who is about to perform an operation on the operation panel 10A is detected as the target object O by the object detection unit 21A, and predetermined information is projected and displayed on the surface of the hand. Therefore, there is no need to display information on the operation panel 10A, and information can be presented to the user without degrading the design of the operation panel 10A. Furthermore, since information is displayed on the hand that is about to perform an operation, it is possible to make the displayed information more noticeable to the user.

[0041] Furthermore, as shown in Projection Examples 1 to 3, the projection device 20A in this embodiment includes a projection control unit 31A that controls the projection unit 22 to project information according to the position of the target object O detected by the object detection unit 21A. With this configuration, it is possible to change the information to be projected according to, for example, the button 11 that the user is about to operate.

[0042] Furthermore, in the projection device 20A of this embodiment, when the object detection unit 21A continuously detects the target object O in a space within a predetermined range from the operation panel 10A for a predetermined time or more, the projection control unit 31A may stop the projection by the projection unit 22. Here, when the target object O is continuously detected for a predetermined time or more, it is highly likely that the target object O is not an object (such as a user's hand) that is attempting to operate the operation panel 10A. Therefore, by stopping the projection by the projection unit 22 when the object detection unit 21A continuously detects the target object O for a predetermined time or more, unnecessary projection by the projection unit 22 can be stopped.

[0043] In the present embodiment, an example has been described in which projection device 20A displays information related to operations on control panel 10A provided inside car 1, but the projection device of the present invention is not limited to this. In one aspect of the present invention, projection device 20A may project information related to operations on a control panel provided at an elevator hall. In this case, object detection unit 21 and projection unit 22 may be provided, for example, above the hall (for example, on the ceiling of a floor).

[0044] Furthermore, in this embodiment, the control panel 10A is configured with buttons 11, but the elevator system 100A of the present invention is not limited to this. In an elevator system according to one aspect of the present invention, the control panel may be configured with a touch panel. In this case, a special instruction (for example, an instruction to cancel a previously input instruction or an instruction to call a wheelchair) can be given by inputting an instruction using a flick operation (in other words, a swipe operation). In this case, the projection control unit 31A may control the projection unit 22 so that the information projected onto the back of the user's hand by the projection unit 22 indicates that the special instruction can be given by performing a flick input. This makes it possible to notify the user that a special instruction can be given by performing a flick input.

[0045] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0046] Fig. 8 is a block diagram showing the configuration of the main parts of an elevator system 100B according to this embodiment. Fig. 9 is a schematic diagram of the periphery of an operation panel 10A inside a car 1 according to this embodiment. As shown in Fig. 8, the elevator system 100B includes a projection device 20B instead of the projection device 20A in the first embodiment. The projection device 20B includes an object detection unit 21B and a control unit 30B instead of the object detection unit 21A and the control unit 30A in the first embodiment.

[0047] The object detection unit 21B includes a camera 41 and a processing unit 42. The camera 41 captures an image of a target object O that exists in a space within a predetermined range from the operation panel 10A. The camera 41 may be provided in a position where it can capture an image of the target object O that exists in a space within a predetermined range from the operation panel 10A. For example, as shown in FIG. 9, the camera 41 may be installed on the ceiling of the car 1.

[0048] The processing unit 42 detects a target object O present in a space within a predetermined range from the operation panel 10A by performing image recognition processing on the captured image taken by the camera 41. The processing unit 42 also identifies the detected position of the target object O by performing image recognition processing on the captured image taken by the camera 41. Furthermore, the processing unit 42 may detect the type of target object O present in a space within a predetermined range from the operation panel 10A by performing image recognition processing on the captured image taken by the camera 41. A conventionally known method can be used for the image recognition processing.

[0049] Furthermore, the object detection unit 21B performs image recognition processing on the captured image captured by the camera 41 to detect the size of the target object O located around the operation panel 10A.

[0050] The control unit 30B includes a projection control unit 31B instead of the projection control unit 31A in embodiment 1. The projection control unit 31B controls the projection unit 22 to project information according to the detection position of the target object O detected by the object detection unit 21B, for example, as in projection examples 1 to 3 described in embodiment 1.

[0051] Furthermore, the projection control unit 31B may stop projection by the projection unit 22 when the object detection unit 21B detects that the target object O is an object that is not normally used for input to the button 11. This makes it possible to stop unnecessary projection by the projection unit 22.

[0052] Furthermore, the projection control unit 31B may stop the projection by the projection unit 22 when the size of the target object O detected by the object detection unit 21B is equal to or larger than a predetermined value. Here, when the size of the target object O detected by the object detection unit 21B is equal to or larger than a predetermined value, it is highly likely that the target object O is not an object (such as a user's hand) that is about to operate the operation panel 10A. Therefore, by stopping the projection by the projection unit 22 when the size of the target object O is equal to or larger than a predetermined value, unnecessary projection by the projection unit 22 can be stopped.

[0053] As described above, the projection device 20B in this embodiment detects the target object O by image recognition using a captured image. This makes it possible to accurately detect the target object O that exists in a space within a predetermined range from the operation panel 10A.

[0054] [Embodiment 3] Another embodiment of the present invention will be described below. Fig. 10 is a block diagram showing the main configuration of an elevator system 100C in this embodiment. As shown in Fig. 10, the elevator system 100C includes a projection device 20C instead of the projection device 20A in the first embodiment. The projection device 20C includes a control unit 30C instead of the control unit 30A in the first embodiment. The control unit 30C includes a projection control unit 31C instead of the projection control unit 31A in the first embodiment, and further includes a state detection unit 32.

[0055] The state detection unit 32 detects the state of the operation input on the operation panel 10A from the detection result of the pressure output from the operation panel 10A. For example, the state detection unit 32 may detect the state of the destination floor for which an operation input is being made from the detection result of the pressure output from the operation panel 10A. Furthermore, the state detection unit 32 may detect the elapsed time since an operation input was made to the operation panel 10A from the detection result of the pressure output from the operation panel 10A. Furthermore, the state detection unit 32 may detect the number of operation inputs to the operation panel 10A from the detection result of the pressure output from the operation panel 10A.

[0056] The projection control unit 31C controls the projection unit 22 to project information according to the operation input state detected by the state detection unit 32. For example, when the state detection unit 32 detects the state of the destination floor for which an operation input has been made, the projection control unit 31C may control the projection unit 22 to project an image indicating the floor number of the destination floor for which an operation input has been made as the destination floor.

[0057] As another example, the projection control unit 31C may control the projection unit 22 to project information according to the elapsed time since an operation input was made to the operation panel 10A, which is detected by the state detection unit 32. For example, when the state detection unit 32 detects the time for which the button 11 is pressed, the projection control unit 31C may control the projection unit 22 to project an image indicating the length of time for which the user is pressing the button. In this way, when the user wants to issue a specific instruction by pressing and holding the button 11, it is possible to show the user how long he or she needs to press and hold the button 11.

[0058] As yet another example, the projection control unit 31C may control the projection unit 22 to project information corresponding to the number of operation inputs to the operation panel 10A detected by the state detection unit 32. For example, a case will be described in which a user presses the button 11 twice to cancel an input instruction. In this case, when the state detection unit 32 detects, from the pressure detection result output from the operation panel 10A, that the button 11 that accepted the input instruction has been pressed, the projection control unit 31C may control the projection unit 22 to project the number of times the user pressed the button 11. Alternatively, the projection control unit 31C may control the projection unit 22 to project the number of presses required for cancellation. This makes it possible to confirm the number of presses of the button 11 required for cancellation.

[0059] As described above, the projection device 20C in this embodiment controls the projection unit 22 so that the projection control unit 31C projects information according to the operation input state on the pendant 10A detected by the state detection unit 32. This makes it possible to change the information to be projected according to the state of operation input being performed on the pendant 10A.

[0060] [Embodiment 4] Another embodiment of the present invention will be described below. Fig. 11 is a block diagram showing the configuration of a main part of an elevator system 100D in this embodiment. Fig. 12 is a schematic diagram of the periphery of an operation panel 10B inside a car 1 in this embodiment. As shown in Fig. 11, the elevator system 100D includes an operation panel 10B and a projection device 20D instead of the operation panel 10A and projection device 20A in the first embodiment.

[0061] The operation panel 10B is provided with a plurality of photoelectric sensors 13 as shown in FIGS.

[0062] A photoelectric sensor 13 is provided for each of the multiple buttons 11. As shown in Fig. 12, the photoelectric sensor 13 in this embodiment is provided inside the button 11. However, the photoelectric sensor 13 does not have to be provided inside the button 11, and may be provided adjacent to the corresponding button 11. Each photoelectric sensor 13 detects an object present within a predetermined distance in the normal direction of the button 11 by emitting light in the normal direction of the button 11 and receiving light reflected by an object present at a predetermined distance in the normal direction of the button 11. The object detection result by the photoelectric sensor 13 is output to the projection device 20D.

[0063] Projection device 20D includes a control unit 30C instead of control unit 30A in embodiment 1. Projection device 20D does not include object detection unit 21A in embodiment 1.

[0064] The control unit 30C includes a projection control unit 31C instead of the projection control unit 31A in the first embodiment.

[0065] The object detection unit 33 detects a target object O present in a space within a predetermined range from the operation panel 10B based on the object detection result by the photoelectric sensor 13 of the operation panel 10B. In other words, the projection device 20D detects a target object O present in a space within a predetermined range from the operation panel 10B by the photoelectric sensor 13. Furthermore, the object detection unit 33 detects the detection position of the detected target object O based on the position where the photoelectric sensor 13 that detected the target object O is installed.

[0066] The projection control unit 31C controls the projection unit 22 to project information according to the detection position of the target object O detected by the object detection unit 33. For example, the projection control unit 31C controls the projection unit 22 to project information according to the detection position of the target object O detected by the object detection unit 33, as in Projection Example 1 or Projection Example 3 described in the first embodiment.

[0067] As described above, the projection device 20D in this embodiment detects the target object O by the photoelectric sensor 13. This makes it possible to accurately detect the target object O that exists in a space within a predetermined range from the operation panel 10B.
