Vibration-induced error correction for touchscreen display in an aircraft
The present invention generally relates to the correction of a vibration-induced error for a touch-screen display, and more particularly to the correction of a vibration-induced error for a touch-screen display in an aircraft.
During operation of the aircraft, crew members may use touch screen display devices to perform various functions, such as entering flight plan data or verifying surrounding weather conditions. These touch-screen display devices can enable fast and efficient entry and review of data and flight conditions, while condensing the function of multiple components into a single screen. The touch screen display device may display one or more user interfaces, where it is possible to navigate by selecting virtual elements displayed on the touch screen display device with, for example, a finger or a stylus. Nevertheless, during operation, the aircraft may encounter turbulence, gravitational forces, or mechanical vibrations, which may cause crew members to have difficulty controlling their movements. In some cases, the flight conditions can also be extremely difficult and cause a crew member wishing to select a particular item on a touchscreen display device to inadvertently select an unwanted item. The crew member may then have to re-enter the desired entry on the touch screen display device, which may require going back in the navigation on the user interface. Having to re-enter the desired selection on the touchscreen display device can create frustration among crew members and decrease efficiency.

This and other features, aspects and advantages of various embodiments will be better known with reference to the following description and accompanying claims. The accompanying drawings, which are incorporated herein and form part of this description, illustrate embodiments of the present invention and, together with the description, serve to illustrate the principles involved.
A detailed presentation of the embodiments intended for those skilled in the art is provided in the description, with reference to the accompanying figures, in which: FIG. 1 is a perspective view of an exemplary portion of an aircraft according to exemplary aspects of the present invention; FIG. 2 is a diagram of an example of interaction with a user interface targeted by the present invention; FIG. 3 is a diagram of an example of interaction with a user interface according to exemplary aspects of the present invention; FIG. 4 is a diagram of an example of interaction with a user interface according to exemplary aspects of the present invention; FIG. Figure 5 shows an exemplary method according to exemplary aspects of the present invention; FIG. Figure 6 shows an exemplary method according to exemplary aspects of the present invention; FIG. 7 shows an exemplary system according to exemplary aspects of the present invention. Reference will now be made in detail to embodiments of the invention, of which one or more examples are illustrated in the drawings. Each example is provided as an explanation of the invention, and not to limit the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit of the invention. For example, features illustrated or described as part of one embodiment may be used with another embodiment to implement yet another embodiment. Thus, it is understood that the present invention covers such modifications and variations that appear in the field of the adjoining claims and their equivalents.
Exemplary aspects of the present invention are directed to systems and methods for correcting a vibration-induced error with a touch screen display device on an aircraft. Touchscreen displays may be used by crew members to enter and review data and flight conditions during the operation of an aircraft. A user interface may be displayed on the touch screen display device, which may allow a crew member to navigate through various menus by selecting virtual items displayed on the screen. For example, a crew member may enter flight plan information into a flight control system by selecting a virtual item displayed on the touch screen display device corresponding to a flight plan by touching the item. virtual with, for example, a finger or a stylus. Once the virtual flight plan element has been selected, a new menu with additional input and / or information options may be displayed to allow fast and efficient entry of flight plan information.
During operation of the aircraft, however, flight conditions may make it difficult for crew members to select a particular virtual item displayed on a touch screen display device. For example, an aircraft may encounter turbulence, gravitational effects, or mechanical vibrations, which may cause a crew member to inadvertently select an item on a touch screen display device that is not not the expected element. In such a case, the crew member may have to re-enter the correct selection, which can cause frustration for the crew member, and decrease the efficiency provided by using a touch screen display device. In addition, if the in-flight vibration conditions continue for a period of time, the crew member may have difficulty re-entering the correct selection, which may further exacerbate the crew member's frustration, and lead to even more decrease in efficiency.
Systems and methods according to exemplary aspects of the present invention can correct vibration-induced input errors on a touch screen display device on an aircraft. For example, systems and methods can provide a user interface on a touch screen display device in an aircraft cockpit. The user interface may include one or more virtual elements corresponding to various functions to be performed by one or more components of the aircraft. For example, a user interface may include virtual elements corresponding to a flight plan or weather conditions, which, when selected, may be used to enter flight plan information or display weather conditions, respectively. A crew member can interact with the virtual element (for example, via a touch interaction with, for example, a finger or a stylus) to perform the associated task.
A processor may be configured to receive data indicative of actual user interaction with the touch screen display device, such as input by the crew member. For example, when a crew member selects a virtual item by, for example, touching the virtual item on the touchscreen display device with the crew member's finger, the processor may receive indicative data. of the selected virtual element.
The processor may be further configured to receive data from one or more vibration sensors located on the aircraft. For example, an accelerometer, a speed sensor, a laser displacement sensor, a proximity sensor, or other vibration sensor may be located in a cockpit of an aircraft. The vibration sensor may be configured to detect a vibration, such as vibration due to turbulence, gravitational force, or mechanical vibrations, and to send data indicative of the detected vibration (for example, data indicative of the duration and the amplitude of the vibration) to the processor. Using this data, the processor can determine whether the interaction of a crew member with a touch screen display device coincides with a detected vibration, which may indicate that an input error may have occurred. location.
The processor may further be configured to receive data indicative of a desired user interaction. For example, one or more tracking devices may be configured to track the interaction of the crew member with the touch screen device. For example, in one embodiment, a camera may be configured to track the movement of a crew member's eye, and further configured to provide the processor with data indicative of the object of the visual focus of the crew. member of the crew when the crew member interacts with the touch screen display device. The focus of the crew member's visual focus may indicate that the crew member intended to select an item corresponding to the focus object of the crew member. Using this data, the processor can compute an input error, such as a difference between a real user interaction and the desired user interaction, as determined by the focus object of the crew member.
In one embodiment, a tracking device, such as a camera, may be configured to track the movement of an input device used by a crew member to make a selection on the touch screen display device. . For example, an input device may be the finger, hand, or arm of a crew member, or an object held by the crew member, such as a stylus. As used herein, the term "stylus" refers to any object used by a crew member to interact with a touch screen display device, and may include, without limitation, a capacitive stylus, a Wacom digitizer , a Bluetooth compatible stylus, a writing instrument, or any other device used to interact with a touch screen display device. When the crew member interacts with the touch screen display device, the tracking device may be configured to track the movement of the input device. Data indicative of the movement of the input device can then be provided to the processor, which can model the movement of the input device when it interacts with the touch screen display device. Using this data, the processor can calculate a desired user interaction based on the device path and a detected vibration. For example, a processor may be configured to model a user interaction when a detected vibration has not occurred. Using this data, the processor can calculate an input error, such as a difference between an actual user interaction and a desired user interaction, as determined based on the tracked motion of the input device.
Using the data indicative of a detected vibration, the processor may be further configured to determine a probability of disturbance. For example, a processor may be configured to determine a probability that an input error was caused by a detected vibration. For example, if an input error is very high, but little or no vibration has been detected before or during the user interaction, a probability of disturbance can be calculated which may indicate a low probability that the Input error was caused by the detected vibration. Nevertheless, if an input error is very high, and a similarly high vibration has been detected before or during the user interaction, a disturbance probability can be calculated that can indicate a high probability that the input error was caused by the vibration detected.
Depending on the input error and the probability of disturbance, the processor can determine a corrected user interaction. For example, if a disturbance probability is not high enough that a detected vibration is likely to have caused the input error, the processor can determine that the corrected user interaction is the interaction. real user. Nevertheless, if a probability of disturbance is high enough that a detected vibration is likely to have caused an input error, the processor can determine a corrected user interaction based on the actual user interaction and the input error. For example, a real user interaction may correspond to a first virtual item displayed at a first location on a user interface. Nevertheless, an input error may indicate that a second virtual element located in a second position on the user interface was a desired user interaction. The processor may be configured to determine that the probability of disturbance is high enough that the detected vibration causes the input error, and correct the actual user interaction at the second location corresponding to the second virtual element by adjusting the interaction real user by the input error. The processor can then send one or more control signals to one or more components of the aircraft to perform a function associated with the second virtual element. For example, the processor may send one or more control signals with a remote device, such as a controller located on the aircraft. Alternatively, the one or more control signals may be one or more instructions made by the processor itself.
In this manner, systems and methods according to exemplary aspects of the present invention can correct a vibration-induced error on a touch screen display device on an aircraft. The exemplary systems and methods of the present invention can have a technical effect of reducing interaction errors, reducing crew member frustration, and increasing efficiency with respect to interactions with the device. touch screen display.

According to exemplary aspects of the present invention, the user interface 120 may include one or more virtual elements displayed on a touch screen display device 118. A user, such as a crew member, may interact with the user. virtual element by real user interaction. In one example, the virtual element may be a visual representation of a push button, and an associated real user interaction may be, for example, a push button interaction on the touch screen display device 118 to realize a function associated with the virtual element.
Each virtual element can be associated with a task to be performed by one or more components of the aircraft. A task may include one or more procedures that are required or recommended to perform for the operation of the aircraft 100.

For example, in some applications A touch screen display device 118 may communicate with the control system 130 via a network. The one or more touch screen display devices 118 may be configured to receive actual user interaction with the user interface 120 and to provide data indicative of the actual user interaction to the control system 130. for example, a user may provide touch interaction with one or more virtual elements via a touch screen of a touch screen display device 118. One or more of the touch screen display devices 118 may send data indicative of the actual user interaction with the virtual element to the control system 130.

In response to receiving data indicative of actual user interaction with a touch screen display device 118, data indicative of a desired user interaction from one or more tracking devices 160, and data indicative of a vibration detected from one or more vibration sensors 170, the control system 130, and more particularly, a processor in the control system 130, can be configured to determine a corrected user interaction corresponding to at least a virtual element selected on a user interface 120 displayed on a touch screen display device 118. The corrected user interaction may be a real user interaction corrected for a vibration induced error.
In response to determining the corrected user interaction, the control system 130 may be configured to send one or more signals (e.g., control signals) to one or more aircraft components (not shown) for perform the task associated with the selected virtual element. The control system 130 may be in cable communication or without cables to the one or more aircraft components.

In response to receiving one or more control signals, the aircraft components may perform a control action to perform at least part of the task. For example, in response to receiving one or more control signals to display a flight plan menu, the touch screen display device 118 may then display the current flight plan for the aircraft 100. Similarly, corrected user interaction with a touch screen display device 118 may be used to control one or more controllers to perform a task associated with the operation of an aircraft, such as, for example, setting a pressurization setting of cabin or light a cabin heater unit.
Referring now to FIG. 2, a diagram of an example of interaction with a user interface is provided. As shown, a user interface 120 is displayed on a touch screen display device 118. As shown, the user interface 120 may include one or more virtual elements 202. For example, as shown, four virtual elements 202A-D are shown. Each virtual element 202 can be associated with a function to be performed during the operation of the aircraft 100. For example, the virtual element 202A can be associated with a flight plan, which, when it is selected, can allow the entry and reviewing a flight plan information. The virtual element 202B may be associated with a terrain map, which, when selected, may allow a graphical representation of the surrounding terrain conditions.

The virtual element 202D may be associated with air traffic conditions, which, when selected, may allow the display of surrounding air traffic, such as another aircraft in the vicinity.
Referring again to FIG. 2, an input device 204 may be used to interact with a user interface 120 displayed on a touch screen display device 118. For example, as shown in FIG. 2, a user interacts with a user interface by touching one or more virtual elements with a user's finger. In another embodiment, an input device 120 may be a hand, an arm, or a stylus. As shown, a user may intend to interact with a particular virtual element 202 displayed on a user interface 120. For example, as shown, a line A corresponding to a desired user interaction is shown. As shown, the user intends to interact with the virtual element 202A, which corresponds to a flight plan. Nevertheless, actual user interaction with a user interface 120 may be impacted by vibration, such as vibration due to turbulence, gravitational forces, or mechanical vibration. For example, the actual user interaction, as represented by the line B, may correspond to an unwanted virtual element, such as the virtual element 202B, which corresponds to a terrain map as shown in FIG. 2. In such a case, actual user interaction may differ from the desired user interaction due to vibration induced error.
Referring now to FIG. 3, a diagram of an exemplary interaction with a user interface according to exemplary aspects of the present invention is provided. As shown, a user interface 120 is displayed on a touch screen display device 118. As shown, a user 206 has a visual focus object 208 in the user's field of view. The object of the visual focus 208 may correspond to one or more virtual elements, such as the virtual elements 202A-D shown in FIG. 2. As shown by the line A, the user 206 intends to interact with the object of the visual focus 208. Nevertheless, as shown by the line B, the actual user interaction with the user interface 120 takes place at an erroneous location 210, where the user input device 204 (i.e., the user's finger) touches the touch screen display device 118. The screen display device Touch 118 may be configured to provide data indicative of actual user interaction to a processor in a control system, such as a processor in a control system 130 shown in FIG. 1. For example, the data indicative of the actual user interaction may be data corresponding to the erroneous location 210.
According to exemplary aspects of the present invention, a tracking device 160 may be used to obtain data indicative of a desired user interaction with a touch screen display device 118. For example, a tracking device 160 may be a camera configured to track the view of a user. In another embodiment, a tracking device 160 may be any device or system configured to track a user's visual focus object 208. The tracking device 160 may be configured to provide data indicative of a user's visual focus object 208 to a processor, such as a processor in a control system 130 shown in FIG. 1. For example, the tracking device 160 may provide a processor with data indicative of a visual focus object 208, and the processor may be configured to determine the user's visual focus object 208 as a function of data provided.
The processor, like a processor in a control system 130, may be further configured to determine an input error 212 based on the data received by the touch screen display device 118 and the tracking device 160. For example , a user may intend to interact with a particular virtual element 202 on a touch screen display device 118, and in order to interact with the virtual element 202, the user can focus on the virtual element When the user interacts with the touch screen display device 118, therefore, the data indicative of a focus object 208 may be data indicative of a desired user interaction. Nevertheless, due to vibration, such as turbulence, the user 206 may interact with the touch screen display device at an erroneous location 210. The processor, such as a processor in a control system 130, may be configured to determine an input error 212 based at least in part on the data indicative of the desired user interaction. The input error 212 may be, for example, a difference between a real user interaction (i.e., an erroneous location 210) on a touch screen display device 118 and an object of the visual focus. 208 of the user 206 (i.e., a desired user interaction).
Referring now to FIG. 4, a diagram of an exemplary interaction with a user interface according to exemplary aspects of the present invention is provided. As shown, a user interface 120 is displayed on a touch screen display device 118. As shown, an input device 204, such as a user's finger, is initially on a path corresponding to a line A during interaction of the user with the touch screen display device 118 before a detected vibration 216 takes place.
According to exemplary aspects of the present invention, a tracking device 160 may be used to obtain data indicative of a desired interaction of the user with a touch screen display device 118. For example, a display device tracking 160 may be a camera configured to track the movement of an input device 204, such as a user's finger, during the interaction of a user with a touch screen display device 118. In another mode In one embodiment, a tracking device 160 may be any other device or system configured to track the movement of an input device 204, such as a wireless system configured to track the movement of a stylus when the stylet interacts with a device. The tracking device 160 may be configured to obtain data indicative of a desired user interaction, such as the movement of an input device. e 204 when the input device 204 interacts with the touch screen display device 118. The tracking device 160 may be further configured to provide data indicative of a desired user interaction, such as movement of an input device 204 to a processor, such as a processor in a control system 130 shown in FIG. 1.
As shown in FIG. 4, as the input device 204 moves to the touch screen display device 118, a detected vibration 216 takes place. When the sensed vibration 216 takes place, the actual motion of the user corresponds to the line B, rather than the line A. The sensed vibration 216 may be a vibration, such as turbulence, gravitational force, or mechanical vibration.

Those skilled in the art, using the descriptions provided herein, will understand that the various steps of all the methods described herein can be modified, adapted, extended, rearranged and / or omitted in various ways without departing from the scope of the present invention. present invention.
In (502), method 500 may include providing for display a user interface on a touch screen display device, the user interface including one or more interactive virtual elements, each virtual element being associated with a function of realized by a component of the aircraft during operation of the aircraft.

In (506), the method may include receiving data indicative of a desired user interaction. For example, a tracking device 160 may be configured to track a user when the user interacts with the touch screen display device 118. For example, the tracking device 160 may track a user's visual focus object. as a visual focus object 208 shown in FIG. 3.

In (510), the method may include determining a corrected user interaction corresponding to at least one selected virtual element based at least in part on the data indicative of the actual user interaction, data indicative of the interaction desired user, and data indicative of the detected vibration. For example, the processor may determine that a detected vibration has caused the actual user interaction to be different from a desired user interaction due to a detected vibration. The processor may correct the user interaction into a corrected user interaction corresponding to the desired user interaction. The corrected user interaction may correspond to at least one virtual element, such as a virtual element 204A-D, displayed on a user interface 120 on a touch screen display device 118.
Referring now to FIG. 6, a method (600) according to exemplary embodiments of the present invention is shown. The method (600) can be used, for example, to determine a corrected user interaction, such as a corrected user interaction determined by a processor (510) in a method (500).
In (602), the method may include determining an input error. For example, an input error may be based at least in part on data indicative of a desired user interaction received by a processor in a control system 130. Data indicative of a desired user interaction may be data received from one or more tracking devices, such as one or more tracking devices 160 shown in FIGS. 2 and 3. The tracking devices may be, for example, one or more cameras.
In addition, the one or more tracking devices, such as one or more tracking devices 160, may be configured to track an object of a visual focus of the user, as shown in FIG. 3. The processor may be configured to determine the input error based at least in part on the data provided by the one or more tracking devices. For example, a tracking device 160 may track an object of a visual focus 208 of a user 206. The tracking device 160 may provide data indicative of the user's visual focus object 208 of the user 206 to the processor. The processor may also receive data indicative of actual user interaction, such as erroneous location indicative data received from a touch screen display device 118. The processor may be configured to determine an error of input, as an input error 212 corresponding to a difference between the object of the visual focus 208 and the erroneous location 210.
Additionally and / or alternatively, the one or more tracking devices may be configured to track the movement of an input device, such as an input device 204 shown in FIG. 4. The processor may be configured to receive data indicative of the movement of the input device, and to model an input when a detected vibration has not occurred. For example, a processor may determine a modeled input 214 when a detected vibration 216 has not occurred based on data provided by a tracking device 160. The processor may be further configured to determine an input error based on of the modeled input and data indicative of real user interaction, such as an erroneous location 210. For example, an input error may be a difference between the modeled input 214 and the erroneous location 210.
In (604), the method may include determining a probability of disturbance. The probability of disturbance may be a probability that an input error was caused by a detected vibration. For example, a processor may receive data indicative of a detected vibration, such as data received by one or more vibration sensors 170. The data indicative of a detected vibration may be, for example, data indicative of amplitude. of a vibration, the moment when a vibration begins, and the duration of the vibration. Based on the data indicative of the detected vibration, the processor can determine a probability that an input error has been caused by the detected vibration. For example, if a high amplitude detected vibration occurs at a time coinciding with a large input error, the processor can determine that there is a high probability that the input error was caused by the detected vibration. . In addition, if little or no vibration occurred during a user interaction in which a large input error is determined, a processor may determine that there is a low probability that the input error has occurred. was caused by the vibration detected.
In (606), the method may include determining whether a disturbance probability is high enough that a detected vibration has caused an input error. For example, if a probability of disturbance is low and an input error is high, the processor may determine that the input error is not likely caused by a detected vibration. In such a case, the processor may disregard the input error, and determine that the corrected user interaction is the actual user interaction received by a touch screen display device 118. Therefore, the processor can use the original input, or actual user interaction, as shown in (608). In this way, a corrected user interaction may be at least partly a function of the probability of disturbance.
If, nevertheless, the probability of disturbance is sufficiently high for a vibration detected to have caused an input error, in (610), the processor can determine whether the function corresponding to the real user interaction is a critical function of security. For example, a real user interaction may correspond to the input of a flight plan parameter that would avoid a collision with another aircraft. A desired user interaction, in contrast, may correspond to the input of a flight plan parameter that would not avoid the collision with another aircraft. In such a case, the processor may determine that the actual user interaction corresponds to a security critical function, and may disregard the input error, and determine that the corrected user interaction is the actual user interaction received by a touch screen display device 118. Therefore, the processor may use the original input, or actual user interaction, as shown in (612). In this manner, a corrected user interaction may be the data indicative of the actual user interaction when the data indicative of the actual user interaction includes the selection of a virtual item that includes a security critical function. .
If, nevertheless, the function corresponding to the real user interaction is not a critical security function, in (614), the processor can adjust the actual user interaction, or input, by the error of 'Entrance. For example, as shown in FIG. 3, an input error 212 may correspond to a difference between an erroneous location 210 and an object of a visual focus 208 of a user 206. The processor may determine that the user 206 intended to interact with the touch screen display device 118 at a location corresponding to the object of the visual focus 208. Therefore, the processor can adjust data indicative of the actual user interaction corresponding to the erroneous location 210 by the input error 212. Thus, the corrected user interaction may be a location on the touch screen display device 118 corresponding to the object of the visual focus 208. In addition, the corrected user interaction may be be a virtual item, such as a virtual item 204A-D corresponding to the location of the visual focus object 208. Similarly, the corrected user interaction may correspond to a virtual item corresponding to the input Modeled 214, as shown in FIG. 4. In this manner, the corrected user interaction may be a virtual item selected on the touch screen interface corresponding to the location of the data indicative of the actual user interaction adjusted by the input error. .
Referring again to FIG. 5, in response to determining a corrected user interaction at (510), (512), the method (500) may include sending one or more control signals to one or more aircraft components for perform at least part of the task associated with the at least one selected virtual element. For example, the processor in a control system 130 may, in response to the corrected user interaction, send one or more control signals to one or more aircraft components to perform at least part of an associated task to the selected virtual element. For example, a selected virtual element may be a virtual element associated with a flight plan, such as the virtual element 202A shown in FIG. 2. The processor may send one or more control signals to a touch screen display device 118 to open a menu corresponding to a flight plan to allow a crew member to enter or review information. flight plan. Thus, as shown in FIG. 2, when the actual user interaction has corresponded to a virtual element 202B, the processor can correct the user interaction, and perform a function corresponding to the selected virtual element 202A. In this manner, the method (500) according to exemplary aspects of the present invention can correct a vibration-induced error with a touch-screen display device.
