The present disclosure generally relates to elevators, including systems and methods for displaying one or more cabin operating panels within an elevator cab based on the position of one or more passengers within the elevator cab.
Elevator cars include car operating panels (COPs) that passengers utilize to specify desired destinations. Elevator manufacturers have recently started including interactive touch-based COPs on the walls of elevator cars to modernize elevator cars and to improve visibility and access to COPs. Yet access to interactive touch-based COPs in elevator cars remains problematic. For example, passengers still have trouble accessing the COP in a crowded elevator car. As another example, passengers still have to move around within an elevator car to access the COP or the portion of the COP that is needed. As still another example, the COPs of many elevator cars are positioned too high or too low for passengers with disabilities. Likewise, the COPs of many elevator cars are positioned too high or too low for passengers that fall outside of an average-height range. Some of these shortfalls with existing COPs are particularly problematic in view of laws such as the Americans with Disabilities Act (ADA) and the Architectural Barriers Act (ABA).
Thus a need exists for systems and methods where virtual COPs in elevator cars are easily accessible to all passengers, including passengers with above-average heights and passengers with below-average heights.
In some examples, an elevator system may generally include an elevator car for transporting passengers between floors of a building, as well as a screen disposed in the elevator car. The screen may in some cases be a touchscreen with a pressure sensitive surface that is LED-backlit and can receive input from passengers regarding, at the very least, destination floors. In some instances, the screen may be configured to display a virtual display panel, such as a virtual car operating panel (COP), for example, only after a passenger interacts with or touches the screen. Once the passenger interacts with or touches the screen, the screen may display the virtual display panel at a location at which the passenger first interacted with or touched the screen. Needless to say, this location will be higher for taller passengers and lower for shorter passengers. To encourage passengers to interact with or touch the screen as they enter the elevator car, the screen may display one or more visual prompts such as fingertips, hands, and/or text that says “touch here,” for example.
Other example elevator systems may generally include an elevator car, a screen, and a sensor system. The sensor system may be disposed in the elevator car and may detect a location, an orientation, and/or a height of a passenger that is entering or present in the elevator car. Some example sensor systems include one or more object detection sensors disposed at various locations throughout the elevator car. Several examples of object detection sensors include cameras, depth sensors, infrared sensors, and imaging luminance meters. Notwithstanding, this information about the passenger may be relayed periodically to the screen or, more precisely, the screen's controller, which may control the content displayed on the screen. The screen may then display a virtual display panel at a location on the screen that is based on the location, the orientation, and/or the height of the passenger in the elevator car. The location of the virtual display panel may be adjusted on the screen if the passenger turns or moves within the elevator car. Indeed, the screen may display as many virtual display panels as there are passengers in the elevator car, and the location of each virtual display panel may be based on the location, the orientation, and/or the height of each respective passenger. It should be understood that the screen controller may be in communication with an elevator controller that controls movement of the elevator car between the floors of the building. Hence when a passenger requests a destination floor on a virtual display panel, the screen controller can relay this request to the elevator controller.
The present disclosure contemplates a wide variety of ways in which to operate screens in elevator cars. In some examples, a screen in the elevator car may be configured to display a virtual display panel before a passenger enters the elevator car. Once the passenger enters the elevator car the screen may adjust the location of the virtual display panel based on information that the sensor system detects about the passenger's location, orientation, and/or height. In other examples, the screen may wait to display a virtual display panel until the sensor system has provided information about the passenger's location, orientation, and/or height.
The example screens disclosed herein are not limited to displaying virtual display panels. Rather, one or more screens in an elevator car may display a variety of media content with which passengers can interact while they are being transported to their respective destination floors. For instance, a screen may display notifications, advertisements, social media, photos, web pages, news briefs, weather forecasts, traffic reports, video clips, and so on. The screen may also offer entertainment options such as a photobooth or a GIF generator that generates media that can be sent to passengers. Media content may be displayed, for example, after a passenger selects a destination floor and the virtual display panel fades from the screen. The media content that the screen controller displays may be based at least in part on the floor to which the passenger requests to travel. Alternatively or additionally, the screen may display such media content alongside, above, and/or below virtual display panels. By way of example, media content intended for children may be displayed in the lower third of the screen before and after a passenger selects a destination floor on a virtual display panel. Still further, when an elevator car is removed from service, the screen(s) in the elevator car may even display information that assists a service technician to service the elevator system.
Although certain example methods and apparatuses are described herein, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all methods, apparatuses, and articles of manufacture fairly falling within the scope of the appended claims either literally or under the doctrine of equivalents. Moreover, those having ordinary skill in the art will understand that reciting “a” element or “an” element in the appended claims does not restrict those claims to articles, apparatuses, systems, methods, or the like having only one of that element, even where other elements in the same claim or different claims are preceded by “at least one” or similar language. Similarly, it should be understood that the steps of any method claim need not necessarily be performed in the order in which they are recited, unless so required by the context of the claims. In addition, all references to one skilled in the art shall be understood to refer to one having ordinary skill in the art. With respect to the drawings, it should be understood that not all components are drawn to scale. Furthermore, those having ordinary skill in the art will understand that the various examples disclosed herein should not be considered in isolation. Rather, those with ordinary skill in the art will readily understand that the disclosure relating to some examples may be combined with and/or equally applicable to the disclosure relating to other examples.
With reference to
Referring now to
Those having ordinary skill in the art will recognize that the present disclosure is not at all limited to the example elevator drive assembly 150 shown in
In some examples, such as the example elevator car 102 shown in
Although the preceding paragraph identifies a virtual COP as a primary example of a virtual display panel, those having ordinary skill in the art will recognize that the virtual display panels 206, 208, 210, 212 may take many other forms. The virtual display panels 206, 208, 210, 212 may display information concerning, for example and without limitation, maintenance, service modes (e.g., maintenance, fire service, VIP, out of service), elevator performance (e.g., elevator efficiency, current speed, electricity usage, number of passengers transported, height above ground level), estimated time to destination, registered call floors, and/or pin code input.
In some examples, the screens 194, 196, 198 may share a controller with the first and/or second COPs 180, 186. In other examples, the screens 194, 196, 198 may each have their own screen controllers that are in wired or wireless communication with one or more COP controllers 216, 218 of the first and/or second COPs 180, 186. In yet other examples, the screens 194, 196, 198 may share a screen controller 220 that is in communication with the COP controllers 216, 218 of the first and/or second COPs 180, 186, as shown in
In some examples, each of the screens 194, 196, 198 may comprise a pressure sensitive surface that is configured as a touchscreen to receive input from a passenger that presses against the pressure sensitive surface. The touchscreen may employ at least one of capacitive technology, resistive technology, infrared technology, or surface acoustic wave technology. In some cases, the pressure-sensitive surface is an LED-backlit piece of tempered glass or chemically-strengthened glass (e.g., alkali-aluminosilicate sheet glass) that is reflective and can selectively display everything from images and video to virtual objects such as buttons. Several example touch-based technologies that the screens 194, 196, 198 may employ include without limitation capacitive touch, infrared, optical imaging, dispersive signal, and/or acoustic pulse recognition technologies. In some cases, the pressure sensitive surface may be scratch-resistant and may have a Vickers hardness of 650+. Nonetheless, input from a passenger to the pressure sensitive surface may be processed by the screen controller 220. The screen controller 220 may then transmit a control signal to the elevator controller 112. Alternatively, input from a passenger received at the screens 194, 196, 198 may be processed by the elevator controller 112. In most or all cases, the screens 194, 196, 198 provide feedback to indicate to a passenger that certain input has been received. For example and without limitation, a floor button displayed on each of the virtual display panels 206, 208, 210, 212 may light up as having been requested to indicate to passengers within the elevator car 102 that a particular floor has been requested and that the elevator car 102 will stop at the requested floor.
In some examples, one or more of the virtual display panels 206, 208, 210, 212—and other content of the screens 194, 196, 198—may be displayed at positions on the screens 194, 196, 198 that are based on the location, orientation, and/or height of one or more passengers that is entering or already present within the elevator car 102. A sensor system 250 may detect the presence, location, orientation, and/or height of each passenger. The screens 194, 196, 198 may then display the virtual display panels 206, 208, 210, 212 and other content at an ideal location for each respective passenger, as the sensor system 250 may be in communication with the elevator controller 112 and/or the screen controller 220. The sensor system 250 may in some examples be disposed above the first screen 194 on the back sidewall 200 of the elevator car 102. In other examples, the sensor system 250 may be disposed above the screen 198 on the left sidewall 204, above the screen 196 on the right sidewall 202, above the first COP 180, above the second COP 186, above the doors 184, and/or on a ceiling of the elevator car 102. In some cases, components of the sensor system 250 may be distributed throughout various locations in the elevator car 102. In some instances, the sensor system 250, or at least one component thereof, may be disposed in or behind one of the screens 194, 196, 198 so as to remain largely or entirely out of view of any passengers.
In some examples, the sensor system 250 may be at least similar to one of the example traffic monitoring systems disclosed in WIPO Patent Publication No. WO2019/043061A1 entitled “Elevator Traffic Monitoring and Control System,” which is hereby incorporated by reference in its entirety.
One of the components of the sensor system 250 such as the object detection sensor 254 may detect one or more passengers 280, 282 that are entering or already present in the elevator car 102, as shown in
The example image 300 of
In some examples, the object detection sensor 254 may include a depth sensor that generates an image of the passengers 280, 282 occupying the elevator car 102 based on the proximity of the passengers 280, 282 to the object detection sensor 254. The processor 252 may use an algorithm to generate a map, much like the map 324 of
It should be understood that the sensor system 250 may include numerous object detection sensors 254 of the same or different types to verify detection of the passengers 280, 282 entering or present in the elevator car 102. As an example where the sensor system 250 includes numerous object detection sensors 254 of the same type, the sensor system 250 may include four imaging luminance meters configured as the object detection sensors 254 and disposed about the walls of the elevator car 102. Luminance generally refers to an amount of light that is emitted, passed through, or reflected from a surface. Because the luminance of a passenger's face is distinguishable from the luminance of the back of the passenger's head, the processor 252 of the sensor system 250 can compare four contemporaneous (or near-contemporaneous) measurements from the four different imaging luminance meters in the elevator car 102 and determine the passenger's orientation.
As an example where the sensor system 250 includes numerous object detection sensors 254 of different types, the sensor system 250 may include a camera as a first object detection sensor 254 and an infrared sensor as a second object detection sensor 254. The camera and the infrared sensor may contemporaneously generate, respectively, the photographic image 300 of
Those having ordinary skill in the art will appreciate that the object detection sensor 254 and the sensor system 250 generally may update the map 324 periodically (e.g., every few seconds, every second, every few tenths of a second, every few hundredths of a second, etc.). To account for any passenger movement within, into, or out of the elevator car 102, the map 324 may in some examples be updated with virtual lines or vectors indicating movement of the signatures 320, 322 and hence the passengers 280, 282 relative to the elevator car 102. In this manner, specific movement of individual passengers 280, 282 may be determined. As shown in
The present disclosure is not limited to identifying the locations of passengers by way of imaging. Rather, the present disclosure contemplates a wide variety of ways by which to identify the location, height, orientation, and/or movement of passengers in the elevator car 102. As merely an example, the sensor system 250 may employ object detection sensors in the form of infrared transmitters and receivers (or “transceivers”) disposed about the walls of the elevator car 102 behind or in the screens 194, 196, 198. The infrared transmitters and receivers may be disposed about the walls of the elevator car 102 such that channeled infrared light paths form a horizontal grid across the elevator car 102. Vertical grids may be utilized as well. Because passengers standing in the elevator car 102 will obstruct one or more of the channeled infrared light paths, the sensor system 250 is able to deduce which portions of the elevator car 102 are occupied by passengers. Moreover, to determine the heights of the various passengers, the sensor system 250 may employ infrared transmitters and receivers disposed at multiple distinct horizontal levels about the walls of the elevator car 102.
The sensor system 250 may periodically provide information to the screen controller 220 and/or the elevator controller 112 regarding the height, position, movement, and/or orientation of any passengers. For each passenger 280, 282 that enters or is present in the elevator car 102, the screen controller 220 may display a virtual display panel 206, 208, 210, 212 at a location on the screens 194, 196, 198 that is most appropriate for each passenger. In some scenarios, most appropriate may mean that a virtual display panel 206, 208, 210, 212 is displayed at a location on one of the screens 194, 196, 198 that is horizontally closest to the passenger and at a height that is approximately chest- or shoulder-level high for that passenger.
The present disclosure contemplates a host of methods for operating the example screens 194, 196, 198 in the elevator car 102. As one example method, the screens 194, 196, 198 may be configured in a sleep mode to conserve energy while no passengers are present in the elevator car 102. The screens 194, 196, 198 may awaken and display several virtual display panels 206, 208, 210, 212 spaced out about the elevator car 102 at one or more periods of time, such as (i) just prior to the opening of the doors 184 of the elevator car 102 to receive passengers, (ii) as the doors 184 open, (iii) when motion is detected within the elevator car 102, and/or (iv) when a passenger touches one of the screens 194, 196, 198. Based on the height, position, movement, and/or orientation of the passenger(s) as determined by the sensor system 250, the screen controller 220 may adjust the position of at least one of the virtual display panels 206, 208, 210, 212. In another example, though, the screen controller 220 may wait to display one or more of the virtual display panels 206, 208, 210, 212 until the sensor system 250 has provided information regarding the passenger's height, position, movement, and/or orientation in the elevator car 102.
In still another example method, the screen controller 220 may wait until a passenger interacts with or touches one of the screens 194, 196, 198 before causing the screens 194, 196, 198 to display a virtual display panel. The screens 194, 196, 198 may then display a virtual display panel 206, 208, 210, 212 at a spot where the passenger first interacted with or touched one of the screens 194, 196, 198. According to this method, the screens 194, 196, 198 may display one or more hands, fingertips, or text such as “touch here” as visual prompts for passengers to touch one of the screens 194, 196, 198 when entering the elevator car 102.
To be clear, the screens 194, 196, 198 may display a virtual display panel 206, 208, 210, 212 for each passenger based on each passenger's height, position, movement, and/or orientation in the elevator car 102. Furthermore, each virtual display panel 206, 208, 210, 212 that is displayed may be updated based on the input of co-passengers in the elevator car 102. For instance, if a first passenger requests to stop at a first destination floor on the first virtual display panel 206, the second virtual display panel 208 may inform a second passenger that the elevator car 102 will stop at the first destination floor by, for example, illuminating a virtual button that corresponds to the first destination floor and/or by highlighting the first destination floor on a virtual projection of the building. The virtual display panels 206, 208, 210, 212 may also inform passengers about scheduled stops that have been requested by passengers that are waiting to be picked up and have yet to enter the elevator car 102.
In some cases, the virtual display panels 206, 208, 210, 212 may remain displayed on the screens 194, 196, 198 even after a passenger has stopped engaging with the screens 194, 196, 198. For example, the first virtual display panel 206 may remain displayed until the first passenger that interacted with the first virtual display panel 206 reaches his or her destination. In other cases, however, each virtual display panel 206, 208, 210, 212 may, respectively, fade on the screens 194, 196, 198 after a period of inactivity (e.g., five seconds, ten seconds, fifteen seconds) where no passengers engage with the respective virtual display panel 206, 208, 210, 212.
Because the screen controller 220 and/or the elevator controller 112 are connected to the Internet (or an intranet that is otherwise connected) by way of a wired or wireless connection, the screens 194, 196, 198 may display, in addition to the virtual display panels 206, 208, 210, 212, an array of media content such as notifications, advertisements, social media, photos, web pages, news briefs, weather forecasts, traffic reports, video clips, and so on. Likewise, this media content may be managed remotely and may be updated continuously, periodically, or at least intermittently with little or no human intervention. Further, the screens 194, 196, 198 may display such media content at the same time as the virtual display panels 206, 208, 210, 212, for instance, alongside, above, and/or below the virtual display panels 206, 208, 210, 212. As one example, media content appropriate for children may be displayed in the lower third of the screens 194, 196, 198, beneath one or more virtual display panels 206, 208, 210, 212. Alternatively or additionally, the screens 194, 196, 198 may display media content for a passenger after the passenger has selected a destination on a virtual display panel 206, 208, 210, 212 and after that virtual display panel 206, 208, 210, 212 fades. In some instances, the media content that is displayed may be based at least in part on the destination that is selected. As an example, if the ninth floor of a building is leased by a trading firm and a passenger requests to travel to the ninth floor, the screens 194, 196, 198 may display financial news after the passenger makes the destination request.
The aforementioned examples of media content that the screens 194, 196, 198 may offer are not in any way limiting. For instance, if a passenger so desires, the object detection sensor 254 of the sensor system 250 or a camera disposed in or behind the screens 194, 196, 198 may enable the elevator car 102 to serve as a photobooth or GIF generator. In some cases, the photobooth or GIF entertainment options may only be available where a single destination is selected and/or where all passengers in the elevator car 102 provide their consent. Directions and timing for the photobooth or GIF generator may be displayed on the screens 194, 196, 198. Photos and/or the GIF file(s) acquired during the trip may then be sent to the passenger's mobile phone number or email, for instance, which may be entered into the screen 194, 196, 198. Alternatively, the photos and/or GIF file(s) may be posted directly to a social media platform of the passenger's choosing. Still further alternatively, the screens 194, 196, 198 may display a QR code, which passengers can capture to retrieve their photos and/or GIF file(s).
In some cases, the screens 194, 196, 198 may display easy access buttons that enable passengers to engage with the most popular types of media content with little to no virtual navigation. Example easy access buttons may concern news and traffic. However, easy access buttons may change depending on the time of day (e.g., lunch suggestions around lunchtime) and/or depending on the forecast (e.g., the weather report when precipitation is expected). In some cases, the screens 194, 196, 198 may even have fingerprint scanners embedded in certain locations. When a passenger enters the elevator car 102 and has his or her fingerprint scanned, the elevator controller 112 may instruct the elevator car 102 to transport the passenger to his or her regular floor, and the screen controller 220 may cause the screens 194, 196, 198 to display the passenger's preferred media content.
In some cases, the screen controller 220 may even “learn” certain passenger's preferences by way of repetition, particularly passengers who utilize the elevator car 102 to reach floors in tall buildings during non-peak hours. By way of example, if each weekday between 7:04-7:07 A.M. a passenger requests that the elevator car 102 transport him or her to the eighteenth floor, the screen controller 220 may eventually start to “know” to display (or seek confirmation to display) local sports highlight clips after the passenger selects the eighteenth floor on a virtual display panel 206, 208, 210, 212 on weekdays between 7:04-7:07 A.M.
Alternatively, in some cases the screen controller 220 may be more direct about a passenger's preferences. As merely an example, the screen controller 220 may identify a frequent passenger and, at least initially, cause the virtual display panels 206, 208, 210, 212 to query the frequent passenger for content preferences (e.g., entertainment; money; lifestyle; health; travel; sports; medicine; science; local news; global news; weather). Of course, these examples of content are not remotely limiting, and each example type of content may have a multitude of subcategories. For instance, choosing entertainment may allow the frequent passenger to further specify preferences for a particular type of social media, trending videos, word challenges, brain games, trivia, pop culture, and/or video games, again, purely as examples. Each time the passenger uses the elevator car 102 thereafter, the virtual display panels 206, 208, 210, 212 may automatically display the passenger's preferred content so long as the screen controller 220 is able to identify the passenger. The virtual display panels 206, 208, 210, 212 may routinely or occasionally provide an option for the passenger to update his or her content preferences. In some instances where numerous passengers are in the elevator car 102, the passenger who has previously specified content preferences may be prompted to confirm his or her identity and/or location within the elevator car 102 before his or her preferred content is displayed. Likewise, in some instances where the elevator system 100 identifies numerous frequent passengers that have previously specified content preferences in the elevator car 102, the virtual display panels 206, 208, 210, 212 may display content that is preferred by the greatest number of passengers, particularly where there is not enough space on the virtual display panels 206, 208, 210, 212 to display preferred content for each passenger. In other instances, the virtual display panels 206, 208, 210, 212 may still display preferred content for each passenger, but may prioritize (e.g., enlarge, broadcast associated audio, display centrally) content that is preferred by the greatest number of passengers.
Still further, the screens 194, 196, 198 may be utilized by service technicians when the elevator system 100 is being serviced. After the elevator car 102 is removed from service (which may occur via the screens 194, 196, 198 in some examples) and/or a service technician enters his or her credentials (e.g., username, password, authorization code, two-step authentication info) via the screens 194, 196, 198, the screens 194, 196, 198 may display manuals, step-by-step instructions, documents, instructional images/videos, two-way video calls, service history, statistical ride data, historical ride data, predictive maintenance information, and so on to assist the service technician and facilitate the servicing of the elevator system 100. Much or all of this information may not be available to passengers of the elevator system 100. Such functionality may be particularly advantageous when the service technician is working at a location where the service technician has a view inside the elevator car 102.
