This is about how to provide content in a mobility aircraft.

Urban Air Mobility (UAM) is a three-dimensional urban air transportation system that connects the ground and the air, and is a next-generation transportation system that can transport people or cargo in the sky above the city. For example, urban air mobility can use a personal air vehicle (PAV), which is capable of vertical takeoff and landing and can move without a runway, as a means of transportation.

Meanwhile, unlike existing helicopters, the aircraft has a plurality of rotating members, for example, four rotors, and can take off, land, and operate by rotating the rotors using power generated from the power members. Additionally, the aircraft is equipped with a terminal for passengers to provide various audio-visual content to passengers. However, when operating an aircraft, there is a problem that noise is generated by various factors such as rotor rotation and wind noise, and the noise flows into the aircraft, causing discomfort to passengers. In particular, when a passenger uses content using a passenger terminal, there is an inconvenience in that the passenger cannot comfortably receive content due to noise inside the aircraft.

Referring to FIGS. 1 and 2, the flying device 100 for urban air mobility according to an embodiment of the present invention provides a space for accommodating passengers inside and includes an HMD (HMD) for providing audio-visual content to the passengers. A vehicle 110 equipped with a Head Mount Display terminal 140, a noise removal unit 120 installed to generate and output offset noise to remove noise from the vehicle 110, and an HMD terminal 140. It may include a content providing unit 130 installed to provide content and output local canceling noise to remove local noise not removed by the canceling noise. Here, local noise may include residual noise not removed by offset noise and noise generated by various factors within the aircraft 110.

The aircraft 110, for example, the aircraft 110 for urban air mobility, may include an aircraft main body 110 and a propellant 112 installed on the aircraft main body 110 to generate propulsion for flight.

The aircraft main body 110 may be provided with a door (not shown) that can be opened and closed so that passengers can board, and a seat 113 installed inside the aircraft main body 110 so that passengers can sit. A main body terminal (not shown) may be installed on the aircraft body 110 to provide various information such as flight information to the occupants, and the main body terminal may be a display that can provide various information such as video information and sound information to the occupants. It can be provided. The main body terminal may be built into the inner wall of the aircraft main body 110 or installed to protrude from the inner wall, and may include a speaker capable of providing sound information. The speaker installed in the main body terminal can be used as the first output member 123 to output offset noise, which will be described later.

The propellant 120 includes a rotating member 112a such as a propeller, a power member 112b for generating power to rotate the rotating member 112a, and a power member for supplying power to the power member 112b (not shown). Poetry) may be included. At this time, the rotating members 112a may be provided in plural numbers, for example, four, and may be arranged in a vertical direction during takeoff and landing of the aircraft 100, and may be provided to change direction so that they are arranged in a horizontal direction during flight. Additionally, the power member may be provided as a rechargeable battery. This aircraft 100 may be equipped with wheels to move on the ground, but because vertical takeoff and landing is possible, it is not necessarily equipped with wheels for takeoff and landing like aircraft such as general passenger aircraft.

A content provider 130 may be installed in the aircraft 110 to provide various audio-visual content, such as game content and entertainment content, to passengers. At this time, the content provider 130 may play various contents as images and sounds on a Head Mounted Display (HMD) so that passengers can experience virtual reality. This content provider 130 may be provided as a terminal such as a computer, and may be installed on the seat 113 where the passenger sits or on the inner wall of the aircraft body 111.

The HMD terminal 140 is provided so that passengers can experience virtual reality during the flight, and can play or display various contents stored in the content provider 130 as images and sounds.

Meanwhile, during flight, the aircraft 100 generates sound outside the aircraft body 111 by the operation of the propellant 112. This sound is mainly generated by the rotation of the rotating member 112a. And the sound generated from the outside of the aircraft body 111 flows into the interior of the aircraft body 111 and generates noise. In addition, as the rotating member 112a rotates, vibration is generated in the aircraft body 111, and this vibration generates noise that is different from the sound generated by the propellant 112, for example, having a different frequency from the sound frequency. In this way, sounds and vibrations generated during flight generate noise inside the aircraft 100, that is, inside the aircraft main body 110, making it inconvenient for passengers to have conversations or to listen to or enjoy various contents on the HMD 140. can cause Therefore, by installing the noise removal unit 120 in the aircraft body 110 so that the occupants can fly in a quiet state, noise generated inside the aircraft body 110 can be removed. Additionally, by using the noise removal unit 120 to additionally remove residual noise that has not been removed, such as local noise, content can be provided more accurately and stably to passengers.

Referring to FIG. 3, the noise removal unit 120 includes a first sensing member 121 for detecting the noise of the aircraft 110, and an offset noise generating member 122 for generating offset noise from the detected noise. And it may include a first output member 123 installed on the aircraft 110 to output the generated offset noise.

The first sensing member 121 may be installed inside the aircraft 110, for example, the aircraft body 111 to detect noise generated inside the aircraft body 111. Here, noise may include waves having an audible frequency that humans can hear, and waves having an inaudible frequency that humans cannot directly hear. For example, waves with an audible frequency may include sounds generated from the propellant 112, and waves with an inaudible frequency that cannot be heard directly by humans include vibrations generated in the aircraft 110 by the propellant 112 or airflow. may include. The first sensing member 121 is capable of detecting the sound generated when the propellant 112 operates outside the aircraft body 111 during flight and flowing into the interior of the aircraft body 111, and the vibration of the aircraft body 111. You can. This first sensing member 121 may be provided as a microphone, a sound detection sensor, a vibration sensor, etc., and at least one may be installed inside the aircraft body 111, for example, on the inner wall of the aircraft body 111.

In this way, by installing the first sensing member 121 inside the aircraft body 111, sound and vibration, that is, noise, inside the aircraft body 111 can be detected.

The offset noise generating member 122 may generate offset noise to remove noise from the output value of the first sensing member 121. The offset noise generating member 122 may generate offset noise having a frequency that is opposite in phase to the frequency of the noise detected by the first sensing member 121. Accordingly, if the offset noise is output to the inside of the aircraft body 111, the noise can be canceled out and removed by the offset noise. For example, the offset noise generating member 122 may generate offset noise having a frequency that is opposite in phase to the frequency of the noise detected by the first sensing member 121. This offset noise generating member 122 may be composed of various structures capable of generating offset noise. For example, the offset noise generating member 122 includes an analog-digital converter (Analog-Digital Conve: ADC) for converting the wave signal output from the first sensing member 121, which is an analog signal, into a digital signal in the form of a pulse, and a conversion device. A digital signal processor (DSP) for generating a canceling noise signal with an opposite phase to the wave signal from a digital signal and a digital-analog converter (DAC) for converting the canceling noise signal into canceling noise. ) may include. Here, it is explained that the offset noise generating member 122 converts or generates the noise detected by the first sensing member 121 into offset noise, but the first sensing member 121 measures the noise and vibration respectively and A wave signal and a second wave signal are output, and the offset noise generating member 122 may combine the first wave signal and the second wave signal to generate a single offset noise from the combined wave signal. The structure of the offset noise generating member 122 and the offset noise generating method are not limited to this and may be changed in various ways.

The first output member 123 may output the offset noise generated by the offset noise generating member 122 to the interior of the aircraft body 111. The first output member 123 may be provided as a speaker, etc., and may be installed at one or more locations in various locations inside the aircraft body 111.

The HMD terminal 140 can provide a virtual reality service to the passenger by displaying content when worn on the passenger's head. The HMD terminal 140 includes an HMD body (not shown) that can be worn on the occupant's head, a second sensing member 145 installed on the HMD body to detect local noise not removed by offset noise, and the sound of the content. It may include a second output member 143 installed on the HMD body to output. Additionally, the HMD body 141 may include a display member 142 for providing images of content to both eyes of the occupant and a tracking member 144 for tracking the movement of the occupant's head.

The HMD body 141 may have the shape of glasses, a headset, or a helmet so that the occupant can wear it on the head.

The display member 142 is mounted on the HMD body 141 and can provide images to both eyes of the occupant.

The second sensing member 145 is installed on the HMD main body 141 and can detect noise inside the aircraft 110. At this time, since the noise inside the aircraft 110 was primarily removed by the noise removal unit 120, the second sensing member 145 detects residual noise that has not been removed by the noise removal unit 120, for example, around the occupants. Local noise can be detected. This second sensing member 145 may be provided with a microphone capable of detecting sound, a vibration sensor capable of detecting vibration, etc.

The second output member 143 is installed in the HMD main body 141 and can output the sound of content. The second output member 143 may be equipped with a speaker, headset, earphone, etc., and may provide the sound of content only to the occupant wearing the HMD terminal 140.

In addition, the HMD body 141 may be equipped with a track pad for operation, a return button, a volume adjustment key, etc., and an interface (not shown) for wired or wireless connection with the content provider 130.

The structure of the HMD terminal 140 is not limited to this and can be changed in various ways.

Meanwhile, when the occupant wears the HMD terminal 140 on the head, the area viewed by the occupant's left eye and the area viewed by the right eye of the display member 142 may be spatially separated. Accordingly, the HMD terminal 140 can reproduce different images on the display member 142 in the area viewed by the passenger's left eye and the area viewed by the right eye, so that different images are incident on the left and right eyes.

The tracking member 144 can track the movement of the occupant's head and may be provided with a gyro sensor, an acceleration sensor, etc. Accordingly, the HMD terminal 140 is implemented to instantly update the field of view image by tracking the occupant's head movement, and can be implemented to provide 3D images as well as 2D images. For example, when a passenger wears the HMD terminal 140 on the head, it completely dominates the passenger's field of view and provides 360-degree stereoscopic images and sounds, and the tracking member 144 provided on the HMD terminal 140 tracks the user's head. When movement is tracked or detected and transmitted to the content provider 130, the content provider 130 can reproduce the content image on the display member 142 to produce a visual effect appropriate for the direction. Accordingly, the passenger can receive a 3D image that exists in the direction his or her gaze is facing among the panoramic 3D images, allowing the passenger to experience virtual reality.

One such HMD terminal 140 may be provided in the aircraft body 111, or may be provided for each seat installed inside the aircraft body 111.

The content provider 130 includes a storage member 131 for storing various audio-visual content such as game content, entertainment content, etc., and an image for playing or displaying the video of the content on the display member 142 of the HMD terminal 140. A volume control member 133 and a second sensor for automatically adjusting the volume of the sound to be output to the second output member 143 according to the local noise detected by the control member 132 and the second sensing member 145. It may include a local canceling noise generating member 134 to remove local noise detected in the member 145. This content provider 130 may be provided by a computer, etc., and may be installed to provide content to one or more HMD terminals 140.

The storage member 131 may be provided as a storage medium such as SSD or HDD.

The display member 142 may be provided as a display such as LCD, OLED, etc., and may be mounted on the HMD body 141 and may be sized to play or display content images on both eyes of the occupant.

The image control member 132 can display the content image on the display member 142, and immediately updates the image on the display member 142 according to the movement of the occupant's head tracked by the tracking member 144, thereby displaying only a 2D image. In addition, it can provide 3D images.

The volume control member 133 can automatically adjust the volume of the content sound according to the local noise detected by the second sensing member 145. In other words, the occupant may adjust the sound of the content using the volume control key mounted on the HMD main body 141, but the sound of the content is automatically adjusted by the volume control member 133 without the occupant's operation, and the second output member ( 143).

The local canceling noise generating member 134 may generate local canceling noise to remove the local noise according to the local noise detected by the second sensing member 145. This local offset noise generating member 134 may generate local noise in the same or similar manner as the offset noise generating member 122 described above. That is, the second sensing member 145 outputs the detected local noise as a wave signal, which is an analog signal, and the local canceling noise generating member 134 outputs the wave signal output from the second sensing member 145 as a digital signal in the form of a pulse. An analog-to-digital converter (ADC) to convert the signal into a signal, a digital signal processor (DSP) to generate a local cancellation noise signal with an opposite phase to the wave signal from the converted digital signal, and a local cancellation noise signal to local cancellation noise. It may include a digital-to-analog converter (DAC) for conversion. Here, it is explained that the local offset noise generating member 134 converts or generates the noise detected by the second sensing member 145 into offset noise, but the second sensing member 145 measures noise and vibration respectively and generates a wave. Each signal is output, and the local cancellation noise generating member 134 may combine these wave signals to generate a single local cancellation noise from the combined wave signal. The structure of the local canceling noise generating member 134 and the local canceling noise generating method are not limited to this and may be changed in various ways.

When the aircraft 110 is equipped with a plurality of HMD terminals 140, the plurality of HMD terminals 140 can detect local noise at each use location. Additionally, the local canceling noise generating member 134 may independently generate local canceling noise to remove local noise detected by each HMD terminal 140.

Through this configuration, the flying device for urban air mobility according to an embodiment of the present invention can accurately and stably provide various audio-visual contents to passengers in a comfortable and quiet environment.

Hereinafter, a method of providing content in an urban air mobility vehicle according to an embodiment of the present invention will be described.

Figure 4 is a flowchart showing a method of providing content in an urban air mobility vehicle according to an embodiment of the present invention.

Referring to FIG. 4, the method of providing content in an urban air mobility vehicle according to an embodiment of the present invention includes a process (S111) of playing content on the HMD terminal 140 worn by a passenger (S111), and the vehicle 110 ), a process of detecting noise (S101), a process of generating offset noise to remove the detected noise (S102), a process of removing noise by outputting offset noise (S103), and removal by offset noise A process of detecting local noise that has not been detected (S112), a process of generating local cancellation noise to remove the local noise (S113), and a process of outputting the local cancellation noise to the HMD terminal 140 to remove the local noise (S114) ) may include. Hereinafter, the process of removing noise from the aircraft 110 will be described. However, the process of playing content on the HMD terminal 140 worn by the passenger includes the process of detecting noise from the aircraft 110 and the process of detecting local noise. It may also be carried out in between.

When the power member 112b is operated for flight, the rotation member 112a may be rotated by the power generated from the power member 112b. At this time, sound is generated by the rotation of the rotating member 112a, and the sound may flow into the aircraft 110, for example, the aircraft body 111. In addition, the rotation of the rotating member 112a causes the aircraft body ( Vibration occurs in 111, and a sound different from the sound flowing from the outside to the inside of the aircraft body 111 may be generated due to the vibration of the aircraft body 111. In this way, the sound flowing from the outside to the inside of the aircraft body 111 and the sound generated by vibration may act as noise to the occupants.

First, the noise of the aircraft 110 can be removed using the noise removal unit 120. Noise inside the aircraft body 111, such as sound and vibration, can be detected using the first sensing member 121 installed on the aircraft 110. When noise is detected by the first sensing member 121, the first sensing member 121 may output a wave signal that is an analog signal. The wave signal output from the first sensing member 121 may be input to the offset noise generating member 122. The wave signal is converted into a digital signal by the analog-to-digital converter (ADC) of the offset noise generating member 122, and the converted digital signal can be input to a digital signal processor (DSP). A digital signal processor can generate a canceling noise signal that has a phase opposite to the frequency of the wave signal. The offset noise signal is input to a digital-to-analog converter (DAC), and the digital-to-analog converter can convert or generate the offset noise signal, which is a digital signal, into offset noise, which is an analog signal.

The offset noise generated by the offset noise generating member 122 may be output to the interior of the aircraft body 111 through the first output member 123. The offset noise output to the inside of the aircraft body 111 causes destructive interference with the noise inside the aircraft body 111, thereby eliminating the noise inside the aircraft body 111.

Meanwhile, when the noise of the aircraft 110 is removed using the noise removal unit 120, the overall noise generated by the aircraft 110 is removed, but there may be residual noise that is not removed by offset noise at each location. This is because noise is detected in a specific area inside the aircraft 110 and offset noise is output. Additionally, when a passenger on board the aircraft 110 talks or listens to music using a personal terminal, noise other than that generated by flight may be generated. Accordingly, local noise may occur due to various causes around the occupants. Such local noise may cause discomfort to passengers in enjoying audio-visual content using the HMD terminal 140.

In order to use content, the passenger can wear the HMD terminal 140 on the head and play or display the content. At this time, the image of the content may be displayed on the display member 142 of the HMD terminal 140, and the sound of the content may be output through the second output member 143.

In this process, the second sensing member 145 installed on the HMD main body 141 can detect local noise around the occupant.

When local noise is detected by the second sensing member 145, the second sensing member 145 may output a wave signal that is an analog signal. At this time, the second sensing member 145 can detect local noise of different sizes depending on the direction in which the occupant's head moves. That is, because the second sensing member 145 is installed on the HMD body 141 worn by the occupant, its position may change whenever the occupant moves. Accordingly, the second sensing member 145 can detect local noise of different sizes depending on the movement of the occupant's head.

When local noise is detected by the second sensing member 145, the second sensing member 145 may generate a wave signal and input it to the local canceling noise generating member 134. The local canceling noise generating member 134 can convert the wave signal into a digital signal using an analog-to-digital converter (ADC), and input the converted digital signal to a digital signal processor (DSP). A digital signal processor may invert the phase of an input digital signal to generate a local cancellation noise signal having an opposite phase to that of the digital signal. And the local cancellation noise signal is input to a digital-to-analog converter (DAC), and the digital-to-analog converter can convert or generate the local cancellation noise signal, which is a digital signal, into local cancellation noise, which is an analog signal.

The local canceling noise generated by the local canceling noise generating member 134 may be output through the second output member 143 installed in the HMD main body 141. The local offset noise output to the second output member 143 causes destructive interference with the local noise coming from the outside of the second output member 143, thereby eliminating the local noise.

In addition, the volume control member 133 of the content provider 130 automatically adjusts the sound level of the content, that is, the volume, according to the level of the local noise detected by the second sensing member 145 (S115) and outputs the second output. By outputting the content to the member 143, the sound of the content can be accurately provided to the occupants regardless of the level of local noise.

As such, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention, and various combinations between the embodiments are also possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims described below as well as equivalents to these claims.
