Background

Elevator hall calls, car calls, and other requests from passengers associated with the elevator are typically provided by a signaling panel. The signaling panel is typically located inside the elevator car or near the elevator doors in the lobby. Traditionally, the request is signaled to the elevator control unit via a button located on the panel. Alternatively, more modern versions may use virtual buttons provided by a touch-sensitive display. Conventional solutions can lead to difficulties for the visually impaired person to detect the car operating panel from the wall first and then the correct button from the car operating panel.

Detailed Description

Fig. 1 illustrates an elevator signal apparatus 100 according to one aspect. The elevator signal apparatus 100 includes: a panel 102 configured to provide information associated with an elevator system; and a processing unit 104. The processing unit 104 is configured to receive the at least one trigger signal and adapt the contrast in the at least one region of the panel 102 based on the received at least one trigger signal. The elevator signaling panel 102 can also include a memory 106 configured to store program instructions that, when executed by the processing unit 104, cause the processing unit 104 to perform programmed functions.

The term "contrast" can refer to differences in brightness, and/or color that make one or more sections of the elevator signal device 100, elements of the elevator signal device 100, or regions of the elevator signal device 100 distinguishable. Referring to color contrast, colors that provide high contrast and also provide sufficient contrast between the content and the background may be used. For example, by using black and white, high contrast can be achieved. The contrasting colors may be colors from different segments of the color wheel or "opposite" colors. Brightness contrast may refer to light reflected from one surface or component as compared to light reflected from another surface or component. In other words, the brightness contrast may depend on the reflective properties of each color and material.

The term "adapt" in connection with "contrast" may mean that the contrast is changed, increased or decreased in at least one section of the elevator signal apparatus 100. The adaptation of the contrast can be done simultaneously (i.e. at the same time) or successively (i.e. first adapting the contrast in a first section and thereafter adapting the contrast in a second section, or successively using different types of adaptation in a single section) in at least one section of the elevator signal device 100.

The phrase "at least one section of the panel 102" may refer to a portion of the panel 102 whose contrast may be independently adapted, such as an edge of the panel, an edge of a signaling button of the panel, a symbol of the signaling button, or the entire face of the panel 102.

For example, the processing unit 106 may be configured to adapt the contrast across the panel 102 when elevator service is limited or fails. The panel 102 of the elevator signaling device 100 can be, for example, all yellow when the elevator is operating at limited speeds or when some landings are unavailable. As another example, the elevator signaling device 100 may be all red when an elevator is out of service.

In another example, the processing unit 104 may be configured to first increase the contrast on the edge of the at least one signaling button and then subsequently increase the contrast on the symbol of the at least one signaling button. In another embodiment, the processing unit 104 may be configured to increase the contrast on the edges and symbols of at least one signaling button simultaneously. In another embodiment, the processing unit 104 may be configured to only increase the contrast on the symbol when increasing the contrast of the at least one signaling button.

In an embodiment, the processing unit 104 may be configured to sense an interaction with at least one signaling button and at least reduce contrast on edges of signaling buttons other than the interacted signaling button.

In an embodiment, the processing unit 104 may be further configured to continuously provide increased contrast on the at least one predetermined signaling button. For example, the alert and emergency stop buttons may continually increase the contrast.

Further, the processing unit 104 may be configured to reduce the contrast of the signaling button when the functionality provided by the signaling button is unavailable. For example, if the panel is a car operating panel in an elevator car, at each moment the panel may only provide an increased contrast on the signalling buttons that can be selected.

In an embodiment, the elevator signal device 100 may comprise a light emitting panel and the processing unit 104 may be configured to control the light emitting panel to provide an adapted contrast. An adapted contrast may be provided by changing the color and/or the light intensity of the light generated by the light-emitting panel.

In an embodiment, the panel 102 may comprise a touch sensitive display. The processing unit 104 may be configured to provide the adapted contrast by changing the color and/or light intensity displayed on the touch sensitive display.

In an embodiment, the processing unit 104 may be configured to provide an adapted, increased or decreased contrast by changing a color on at least one edge of the panel, on at least one signaling button, or on the entire panel when the doors of the elevator are about to open or close.

In an embodiment, the processing unit 104 may be configured to adapt the contrast by changing a color on at least one edge of the panel, on at least one signaling button, or on the entire panel when the elevator is about to accelerate or decelerate. Thus, the passenger may be able to prepare for the change in movement of the elevator car. The information provided may help, for example, the elderly to maintain balance with groups with particular needs.

In an embodiment, the elevator signaling device (e.g., car operating panel) may have both physical signaling buttons and signaling buttons provided by a touch-sensitive display. For example, the signaling buttons that provide the security function (such as the alarm button) may be physical buttons, while the remaining signaling buttons (such as the floor buttons) may be provided by a touch-sensitive display.

In an embodiment, the elevator signaling device 100 may be a car operating panel located inside an elevator car. In another embodiment, the elevator signaling device 100 can be a landing signaling device, such as a destination operating panel or a landing call panel.

Further, in an embodiment, at least one of the panel 102, the processor 104 and the memory 106 may constitute means for receiving at least one trigger signal and means for adapting a contrast in at least one region of the panel 102 based on the received at least one trigger signal.

Fig. 2A-2E illustrate examples of adapting the contrast of an elevator signal device. The elevator signaling device illustrated in fig. 2A-2E may be a car operating panel inside an elevator car. Fig. 2A-2E illustrate simplified examples, and the car operating panel may refer to a full-height or partial-height car operating panel, a vertical type car operating panel, or a horizontal type car operating panel.

Fig. 2A illustrates a situation where an elevator car including an elevator signaling device is not moving between floors. The panel 200 of the elevator signaling device and the signaling buttons 208, 212 provided by the panel 200 may be first indistinguishable from the walls of the elevator car, e.g., completely flat and of the same color as the walls of the elevator car. Furthermore, the edge 202 of the panel 200 and the edge 206 of the signaling button 208 may have no contrast at first, or they may have a low contrast, compared to the surrounding elements of the elevator signaling device. These edges may thus be completely or almost completely mixed into the surroundings, i.e. the walls of the elevator car, and appear "invisible". In fig. 2A, the edge 202 of the panel 200 is indicated with a dashed line for illustration purposes, and the edge 202 may not be distinguishable from the wall of the elevator car.

In fig. 2B, the contrast may be adapted, e.g. increased, on at least one edge of the panel 200. For example, if the front panel of the elevator signaling device is white, the edge 202 of the panel 200 may become black, as illustrated by the solid line in fig. 2B. In another embodiment, the contrast may be adapted only on some of the edges 202 (e.g., left and right edges or top and bottom edges). The adapted contrast may be provided after receiving the first trigger signal. The first trigger signal may be received, for example, in response to opening of an elevator car door, for example, as detected by a door sensor. Alternatively, the first trigger signal may be received in response to detecting an approaching passenger, for example by a motion detector or camera. The first trigger signal indicating an approaching passenger may also be based on a user identification, e.g. a short range transceiver identifying the passenger carrying a Radio Frequency Identifier (RFID) tag or a wireless communication device. The adapted or increased contrast on the edge 202 of the panel 200 may help the passenger perceive the panel 200, thus revealing the location of the elevator signaling device to the passenger. Section 204 of panel 200 illustrates an indicator showing the current floor of the elevator car. Although illustrated in fig. 2B-2F, this section may or may not be present in the panel 200.

In fig. 2C and 2D, the contrast may be decreased on at least one edge of the panel 200 and increased on at least one signaling button 206, 212 provided by the panel 200. The elevator signal device may have received a second trigger signal indicating that a passenger is now approaching or has reached the proximity or close proximity of the elevator signal device. An approaching passenger may be detected, for example, by a light curtain of the elevator doors or a separate sensor inside the elevator car. Alternatively, the second trigger signal may be received in response to detecting an approaching passenger, for example by a motion detector or camera. The second trigger signal indicative of an approaching passenger may also be based on a user identification, e.g. a short range transceiver identifying the passenger carrying an RFID tag or a wireless communication device. Further, in another embodiment, the second trigger signal may be a timer expiration signal received from a timer that starts when the first trigger signal is received.

Since the passenger already knows the position of the signaling device due to the adapted contrast as illustrated in fig. 2B, the indication of the panel position may no longer be needed and the contrast on the edge of the panel 200 may be reduced. Because knowledge of the location of the signaling buttons 206, 212 is necessary for the passenger, the contrast of the signaling buttons 202 may be increased to reveal the signaling buttons. The increased contrast on the signaling button 202 may be provided simultaneously or sequentially, meaning that the contrast may be provided first only on the edges of the signaling button 206, as illustrated in fig. 2C, and thereafter also on the symbols of the signaling button 206, as illustrated in fig. 2D. In another example, the contrast on the edge 202 of the panel 200 may remain in an increased state simultaneously with the increased contrast state of the signaling buttons 206, 212.

In fig. 2E, the button 210 has been signaled that an interaction was sensed. In response to the interaction, the contrast may be reduced at least on the edges 206 of the signaling buttons 208 other than the interactive signaling button 210. For example, the passenger may have selected his destination floor by selecting a physical signaling button 210 or clicking on a virtual signaling button 210 provided by a touch-sensitive display. The contrast on the selected button may remain unchanged and the contrast of all other signaling buttons may be reduced. As shown in fig. 2E, the contrast on the other buttons 208 than the button 210 may be reduced only on the edges of the buttons, and thus the passenger can identify the unselected buttons by their symbol, enabling a new selection to be made later.

Fig. 2F illustrates a situation in which the elevator car is already moving. Since the elevator car has passed these floors, the floor numbers 1 and 2 are no longer visible/selectable. Floor 3 is still indicated as the selected floor by providing contrast on both the edge and the symbol of the signaling button 210. However, for floor 4, contrast may be provided only on the symbol, indicating that the floor may still be selected.

In an embodiment, the contrast on all non-selected signaling buttons 208 may be reduced on the edge 206 and on the symbol of the button, while the selected button 210 has an increased contrast. The contrast on the signaling button 208 may be increased when the elevator car passes the floor associated with the signaling button 208 while the elevator car is moving. When the floor associated with the signaling button 208 has been passed, the contrast of the signaling button 208 may again be reduced.

In an embodiment, at least one predetermined signaling button 212 (such as an alarm button, a door open button, and/or a door close button) inside the elevator car may constantly have an increased contrast. Alternatively, the increased contrast can be provided on at least one predetermined signaling button only when the elevator car is moving. Also, in another example, the signaling button that is not available to the passenger may remain hidden. For example, if one or more floors of a building are closed or locked only for certain groups of people, the floor call buttons of these floors will not be provided with enhanced contrast.

In embodiments, "opposite colors" (e.g., black and white) or colors that provide high contrast differences may be used. In other words, the first color and the second color may alternate when providing an adapted contrast. For example, the panel of the elevator signaling device may first use a first color. Then, thereafter, the edge of the signaling button may be set with the second color while the remaining portion of the signaling button may be set with the first color. Thereafter, the symbol of the signaling button may be set with a first color.

In another embodiment, a single color (e.g., white) may be used as the primary contrasting color. This means that in contrast adapted sequences, white is always used as contrast color, whereas the previous sequences always turn back to black. As an example, the panel of the elevator signaling device may be black first. Then, the edge 202 of the panel 200 may be provided with white. Then, the edge of the signaling button may be set to white while the edge of the panel 200 turns back to black. Thereafter, the symbol of the signaling button may be set to white while the edge of the signaling button turns back to black.

In an embodiment, e.g. in the indicator zone 204, an arrow with increased contrast during landing can be provided, e.g. to indicate the correct direction towards the elevator door to be opened in an elevator car with doors on opposite sides of the elevator car. During the stop, the contrast on the arrow may be alternately increased and decreased to create a flickering effect. In another example, an arrow with increased contrast can be provided to indicate the up and down movement direction of the elevator car when the elevator moves, for example, in indicator section 204.

Fig. 2G illustrates an exemplary elevator car 216 that includes the elevator signaling device illustrated in fig. 2A-2F.

Fig. 3A-3E illustrate adapting the contrast of an elevator signal device. The elevator signaling device illustrated in fig. 3A-3E may be a hall call device, and it may be a stand-alone device or installed in a wall of a landing floor.

Fig. 3A may relate to a situation in which the elevator lobby is empty. The panel 300 and the signaling buttons 312 of the panel 300 may be completely flat and have the same color as the wall of the hallway. Further, the edge 302 of the panel 300 and the signaling button 312 may have no contrast, or it may have a low contrast compared to surrounding elements. This situation means that the panel 300 and the signaling button 312 may not be distinguishable from the wall portion when there is no passenger at the lobby. Thus, the panel 300 and signaling buttons may blend completely or nearly completely into the surrounding environment (i.e., wall portions) and appear "invisible". In fig. 3A, the edge 302 of the panel 300 is shown in dashed lines for illustrative purposes, and the edge 302 may not be distinguishable from a wall of an elevator lobby.

In fig. 3B, the contrast may be adapted on at least one edge 302 of the panel 300. As an example, if the panel 300 is white, the edge 302 of the panel 300 may become black, as illustrated with a solid line in fig. 3B. In another example, the contrast may be adapted or increased only on some of the edges 302 (e.g., left and right edges, or top and bottom edges). An adapted or increased contrast may be provided immediately, gradually increasing or by light effects, such as a circulating light around the edge 302 of the panel 300 or having a sparkling effect.

An adapted or increased contrast may be provided after receiving the first trigger signal. For example, the first trigger signal may be received in response to an approaching passenger being detected with the first sensor. The first sensor may be, for example, a motion detector or a camera. The first trigger event indicating an approaching passenger may also be based on a user identification, e.g., a short range transceiver identifying the passenger carrying an RFID tag or wireless communication device. Furthermore, the first sensor may be integrated into the elevator signal device, or there may be a wired or wireless connection with the first sensor. Alternatively, the first trigger signal may originate from the elevator controller. The adapted or increased contrast on the edge 302 of the panel 300 helps the passenger perceive the panel 300, thus revealing the location of the elevator signaling device to the passenger.

In fig. 3C and 3D, the contrast may be reduced on at least one edge 302 of the panel 300 and increased on the signaling button 310 provided by the panel 300. The elevator signal device may have received a second trigger signal indicating that a passenger has arrived in the vicinity of the elevator signal device. An approaching passenger may have been detected with a second sensor that may scan the immediate area of the elevator signal device 100. The second sensor may be, for example, a motion detector or a camera. The second trigger signal indicative of an approaching passenger may also be based on a user identification, e.g. a short range transceiver identifying the passenger carrying an RFID tag or a wireless communication device. Further, the second trigger signal may also be a timer expiration signal received from a timer that starts when the first trigger signal is received. Alternatively, the second trigger signal may originate from the elevator controller. Since the passenger already knows the position of the signaling device, an indication of the position is no longer needed and the contrast on the edge 302 of the panel 300 can be reduced. Because knowing the location of the signaling buttons 312 is necessary for the passenger, the contrast of the signaling buttons 312 may be adapted or increased in order to reveal the signaling buttons. The adapted or increased contrast on the signaling button 312 may be provided simultaneously or sequentially, which means that the contrast may be provided first only on the edges of the signaling button, as illustrated in fig. 3C by the marker 310, and thereafter also on the symbol of the signaling button, as illustrated in fig. 3D by the marker 312. In another example, the contrast on the edge 302 of the panel 300 may be maintained in an increased state simultaneously with signaling an increased contrast state of the buttons 310, 312.

Fig. 3E illustrates a situation where the passenger has selected the up button. In the signaling button 314, contrast is provided in the up button on both the edge and the symbol. In the unselected down buttons, contrast is provided only on the symbol.

Fig. 4A-4D illustrate adapting the contrast of a destination operations panel 400 according to one aspect.

Fig. 4A may relate to a situation in which the elevator lobby is empty. Further, the edge 402 of the panel 400 and the signaling button 408 may have no contrast or a lower contrast at this time. If the destination operations panel 400 is installed in a wall section, the panel 400 may blend into the surrounding environment and appear "invisible". In fig. 4A, the edge 402 of the panel 400 is shown in dashed lines for illustrative purposes, and the edge of the panel 400 may not be distinguishable from the walls of the elevator lobby.

In fig. 4B, the contrast is adapted or increased on at least one edge 402 of the panel 400. The contrast may be adapted or increased on all sides of the panel, or alternatively, the contrast may be adapted or increased only on some of the edges 402 (e.g., left and right edges, or top and bottom edges). For example, if the panel 400 is white, the edge 402 of the panel 400 may become black, as illustrated in fig. 4B with a solid line. An adapted or increased contrast may be provided immediately, gradually increasing or by light effects, such as a circulating light or flashing effect around the edge 402.

An adapted or increased contrast may be provided after receiving the first trigger signal. The first trigger signal may be received in response to an approaching passenger being detected with the first sensor. The first sensor may be, for example, a motion detector or a camera. The first trigger event indicating an approaching passenger may also be based on a user identification, e.g., a short range transceiver identifying the passenger carrying an RFID tag or wireless communication device. Further, the first sensor may be integrated into the destination operations panel 400, or there may be a wired or wireless connection to the first sensor. Alternatively, the first trigger signal may originate from the elevator controller. The adapted or increased contrast on the edge 402 of the panel 400 helps the passenger perceive the panel 400, thus more clearly revealing the location of the destination operations panel 400 to the passenger.

In fig. 4C and 4D, the contrast may be decreased on at least one edge 402 of the panel 400 and increased on the signaling buttons 406, 408 provided by the panel 400. In another example, the contrast may remain in an increased state on the edge 402 even if the contrast is increased on the signaling buttons 406, 408. The destination operations panel 400 may have received a second trigger signal indicating that the passenger has reached the vicinity of the destination operations panel 400. An approaching passenger may have been detected with a second sensor that may scan the immediate vicinity of the destination operations panel 400. The second sensor may be, for example, a motion detector or a camera. The second trigger signal indicative of an approaching passenger may also be based on a user identification, e.g. a short range transceiver identifying the passenger carrying an RFID tag or a wireless communication device. Further, the second trigger signal may also be a timer expiration signal received from a timer that starts when the first trigger signal is received. Alternatively, the second trigger signal may originate from the elevator controller. Since the passenger already knows the position of the destination operating panel 400, an indication of the position is no longer needed and the contrast on the edge 402 of the panel 400 can be reduced. Because knowledge of the location of the signaling buttons 406, 408 is necessary for the passenger, the contrast of the signaling buttons 406, 408 may be increased to reveal the signaling buttons. The increased contrast on the signaling buttons 406, 408 may be provided simultaneously or sequentially, which means that the contrast may be provided first only on the edges of the signaling buttons, as illustrated in fig. 4C by the marker 406, and thereafter also on the symbols of the signaling buttons, as illustrated in fig. 4D by the marker 408.

Section 404 of panel 400 illustrates displaying floor selections and/or a selected number of passengers. Section 404 may be initially invisible or not provided with contrast or provided with low contrast, and when the contrast on signaling buttons 406, 408 is increased, the contrast of section 404 may also be increased. In an embodiment, section 404 may include an arrow and the contrast on the arrow may be increased when the elevator moves to indicate the direction of upward or downward movement of the elevator car.

Thus, only information useful to the passenger at each moment is presented to the passenger. The solution enables to meet different levels of usability requirements by adapting the contrast as needed for signaling.

Fig. 5 illustrates a block diagram of a controller 500 of an elevator system according to one aspect. The controller 500 includes at least one processor 502 connected to at least one memory 504, and an input/output interface 506 connected to at least one processor 506. The at least one memory 504 may include program instructions that, when executed by the at least one processor 502, cause the controller 500 to receive at least one trigger event; and sending at least one trigger signal to the elevator signal device in order to adapt the contrast in at least one zone of the panel of the elevator signal device. The at least one section of the panel may comprise, for example, the entire panel, at least one edge of the panel, or a particular sub-section of the panel.

In an embodiment, the at least one memory 504 stores program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to receive a first trigger event from the first sensor, the first trigger event indicating an approaching passenger. In this case, the at least one trigger signal comprises a trigger signal to adapt the contrast in the first region of the panel. The first sensor may be, for example, a motion detector or a camera. The first trigger event indicating an approaching passenger may also be based on a user identification, e.g., a short range transceiver identifying the passenger carrying an RFID tag or wireless communication device. Alternatively, the controller 500 may be configured to receive a first trigger event from a door sensor, the first trigger event indicating that the elevator car door is open. The first section may comprise, for example, an edge of a panel.

In an embodiment, the at least one memory 504 stores program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to receive a triggering event from at least one of a sensor inside the elevator car or a door sensor, the triggering event indicating an approaching passenger. In this case, the at least one trigger signal comprises a second trigger signal to adapt the contrast in the second region of the panel. Optionally, the controller 500 may be configured to receive a second trigger event from a second sensor, the second trigger event indicating a passenger near or in close proximity to the elevator signal device 100. The second sensor may be, for example, a motion detector or a camera. The second triggering event indicating an approaching passenger may also be based on a user identification, e.g., a short-range transceiver identifying the passenger carrying an RFID tag or wireless communication device. Further, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to receive a second trigger event from a timer that expires after a predetermined time from the first trigger event. The second section may include a signaling button, such as a panel.

The second trigger signal may be configured to control the elevator signaling device to increase contrast on an edge of the at least one signaling button and to increase contrast on a symbol of the at least one signaling button. Furthermore, the second trigger signal may be configured to control the elevator signaling device to increase the contrast only on the symbol of the at least one signaling button.

In an embodiment, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to receive information about interaction with the at least one signaling button and control the elevator signaling device to reduce contrast at least on edges of the signaling buttons other than the interacted signaling buttons.

Further, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to control the elevator signaling device to reduce the contrast of the signaling button when the functionality provided by the signaling button is unavailable.

Additionally, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to control the elevator signaling device to constantly provide increased contrast on the at least one predetermined signaling button.

In an embodiment, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to control the elevator signal device to provide increased or decreased contrast by changing the color displayed on the touch sensitive display.

In an embodiment, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to control the elevator signaling device to provide adapted, increased or decreased contrast by changing a color on at least one edge of the panel, on at least one signaling button, or on the entire panel when elevator service is limited or faulty.

In an embodiment, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to control the elevator signaling device to provide adapted, increased or decreased contrast by changing a color on at least one edge of the panel, on at least one signaling button, or on the entire panel when the door of the elevator is about to open or close.

In an embodiment, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to control the elevator signaling device to provide adapted, increased or decreased contrast by changing a color on at least one edge of the panel, on at least one signaling button, or on the entire panel when the elevator is about to accelerate or decelerate.

In an embodiment, the at least one memory 504 may store program instructions that, when executed on the at least one processing unit 502, cause the controller 500 to receive the second trigger event from a timer that expires after a predetermined time from the first trigger event.

The controller 500 may be a control entity configured to implement only the operating features disclosed above, or it may be part of a larger elevator control entity, such as an elevator controller or group control. Thus, fig. 5 illustrates a solution in which the control entity controlling the elevator signal devices can be arranged as a separate entity from the elevator signal devices.

Further, in an embodiment, at least one of the processor 502 and the memory 502 may constitute means for receiving at least one triggering event; and means for sending at least one trigger signal to the elevator signal device in order to adapt the contrast in at least one zone of the panel of the elevator signal device.

Fig. 6 illustrates a flow chart of a method for an elevator signal apparatus according to one aspect.

At 600, at least one trigger signal is received. The trigger signal may indicate, for example, the approach of a passenger to an elevator signal device located in an elevator lobby, the opening of an elevator car door, a deceleration or acceleration phase of an elevator car, or an operating state of an elevator car. Various examples and alternatives for the meaning of the at least one trigger signal have been discussed in the examples illustrated in fig. 1-5.

At 602, contrast in at least one region of a panel may be adapted based on the received at least one trigger signal. The at least one section of the panel may comprise, for example, the entire panel, at least one edge of the panel, or a particular sub-section of the panel. Various examples and alternatives for at least one section of the panel have been discussed in the examples illustrated in fig. 1-5.

Fig. 7 illustrates a flow chart of a method for a controller of an elevator system.

At 700, at least one trigger event is received. The at least one triggering event may include a triggering event received, for example, from a sensor indicating an approaching passenger, from a door sensor indicating an opening of an elevator car door, or from other means for identifying a passenger. The at least one triggering event may also be associated with an operational state of the elevator system or elevator car.

At 702, at least one trigger signal can be sent to an elevator signal device to adapt contrast in at least one zone of a panel of the elevator signal device. The at least one section of the panel may comprise, for example, the entire panel, at least one edge of the panel, or a particular sub-section of the panel. Various examples and alternatives for at least one section of the panel have been discussed in the examples illustrated in fig. 1-5.
