Description

Content output device and method considering the driving lane of a vehicle {APPARATUS AND METHOD FOR DISPLAYING CONTENTS BY CONSIDERING THE TRAFFIC LANE OF VEHICLE}

The present invention relates to a content output device and method considering the driving lane of a vehicle. More specifically, it relates to a content output device and method considering the driving lane of a vehicle that can selectively provide video content and image content depending on the lane in which the vehicle is traveling.

The importance of digital advertising content has increased with the spread of digital devices and the growth of the digital advertising content market, and with the advent of the digital and multi-platform era, advertising content has also been rapidly reorganized to focus on digital advertising content.

Unlike existing analog advertising content, which was previously printed in paper form, digital advertising content can be provided by combining various graphically processed images and voices, and can provide many stories, messages, and images through advertising content over a certain period of time. Because it can be delivered, it has the advantage of increasing consumers' curiosity or interest, thereby increasing the effectiveness of advertising content.

Due to these various advantages and advertising content effects of digital advertising content, advertisers who provide existing analog advertising content can reorganize analog advertising content into digital advertising content and provide digital advertising content using displays such as TVs and smartphones. By providing digital advertising content through the device, the advertising target was promoted.

In addition, due to the various advantages and advertising effects of digital advertising content, digital advertising content was provided by separately installing a display device to provide digital advertising content even in places where devices capable of providing digital advertising content were not equipped. For example, by installing a content output device with a display in public transportation that people frequently use, such as buses, subways, and taxis, and outputting digital advertising content using the installed content output device, public transportation passengers can use digital advertising content while moving. We encourage easy access to advertising content.

Recently, a method of outputting digital advertising content while the taxi is driving has been introduced by combining a taxi's taxi indicator light with a display device capable of outputting digital advertising content.

However, in the case of combining taxi lights and display devices to output video-type digital advertising content, the attention of drivers driving in other lanes may be focused for a long period of time, increasing the risk of traffic accidents. Additionally, because the location of the display device where digital advertising content is output is outside of the driver's field of view for safe driving, there is a problem that it may lead to a serious accident due to the driver's inability to look ahead.

Therefore, a method is needed that maintains the effectiveness of digital advertising content but does not interfere with the driving of drivers driving in other lanes.

Here, when not only the vehicle 1 equipped with the content output device 100 but also a vehicle running in another lane is stopped, the control unit 130 displays the first display 110 and the second display ( 120) can be controlled to output video content. For example, based on the traffic situation information received by the content output device 100 from the external server 2, it is determined that there is severe traffic congestion on the road on which the vehicle 1 is currently driving, and the vehicle 1 is stopped for a long time. When driving at a low speed or below the preset first reference speed, the control unit 130 causes the first display 110 and the second display 120 to output video content, so that the driver of a vehicle stopped nearby can It can attract attention and improve the effectiveness of content output. Thereafter, when it is determined that the traffic congestion has been alleviated based on the traffic situation information or the speed of the vehicle 1 exceeds the first reference speed and the driving state is changed, the control unit 130 displays the first display 110 and the first display 110. 2 Image content can be controlled to be output on the display 120. Here, the external server 2 may be a road construction server that stores road traffic situation information.

In some embodiments, when the speed of the vehicle 1 exceeds the preset third reference speed, the control unit 130 controls the first display 110 and the second display 120 to display the first display 110 and the second display 120. No content can be output from the first display 110 and the second display 120. When a vehicle (1) is driving at high speed in a space such as a highway, a serious accident may occur in a split second if the vehicle takes a different action or looks somewhere else while driving. Therefore, when the vehicle 1 is driving at high speed in a space such as a highway, the control unit 130 controls no content to be output from the first display 110 and the second display 120, thereby allowing the vehicle 1 to drive in a different lane. It has the advantage of preventing drivers from being distracted while driving by content and eliminating the possibility of accidents occurring through content output.

Additionally, the control unit 130 may control the first display 110 and the second display 120 not to output any content when the vehicle 1 is in a left-turn driving state or a right-turn driving state. When the vehicle (1) turns left or right, there are more risk factors than when driving straight, so you must pay more attention to the front. At this time, when video content or image content is output from the content output device 100, attention may be taken away by the content provided by the content output device 100, which may lead to an accident. Accordingly, the control unit 130 displays the first display 110 and the first display 130 when the vehicle 1 is turning left or right, driving in another lane, or when another vehicle is turning left or right together with the vehicle 1. 2 The display 120 can be controlled not to output any content. Thereafter, when the vehicle 1 changes from a left turn driving state or a right turning driving state to a straight driving state, the control unit 130 displays the first display 110 and the second display 120 according to the lane in which the vehicle 1 is traveling. ), you can control to output either video content or image content. However, it is not limited to this, and when the vehicle 1 is driving on a lane adjacent to the sidewalk or turns left or right along the lane adjacent to the sidewalk, video content is displayed through the first display 110 provided in the direction of the sidewalk. It can be controlled so that no content is output through the second display 120 provided in the direction of the roadway. In some embodiments, the controller 130 may control image content to be output from the first display 110 and the second display 120 when the vehicle 1 is determined to be in a parked state. If video content is output for a long time while the vehicle 1 is parked, a lot of power must be continuously consumed to output video content, so a content output device 100 or a vehicle ( The battery (not shown) provided in 1) may be discharged due to excessive consumption. Additionally, if the vehicle 1 is parked in a space such as an underground parking lot with few people, the content output effect cannot be properly seen even if video content is output for a long time.

Accordingly, when the vehicle 1 is determined to be in a parked state, the control unit 130 controls the first display 110 and the second display 120 to display an image You can control the posting of content. However, it is not limited to this, and the controller 130 may control the first display 110 and the second display 120 not to output both video content and image content when the vehicle 1 is in a parked state. .

In some embodiments, when the vehicle 1 is stopped in a lane adjacent to a sidewalk, the controller 130 outputs video content through the first display 110 and image content through the second display 120. However, when the vehicle 1 changes from the stopped state to the parked state, the video content output from the first display 110 can be changed to image content. Additionally, the control unit 130 may control the first display 110 and the second display 120 not to output any content when the vehicle 1 remains parked for a preset time.

In some other embodiments, when the vehicle 1 is in a parked state, video content can be controlled to be output on the first display 110 and the second display 120, and the vehicle 1 maintains the parked state. When the time exceeds a preset time, the first display 110 and the second display 120 can be controlled to output image content, or can be controlled not to output any content.

In some embodiments, when the vehicle 1 is in a low-speed driving state in a lane adjacent to a sidewalk at a low speed below a preset first reference speed, the first display 110 outputs video content and The second display 120 can be controlled to output image content. At this time, when the speed of the vehicle 1 changes to a high-speed driving state exceeding the preset second reference speed, the control unit 130 causes the first display 110 and the second display 110 to output image content. You can control it.

When the vehicle in which the content output device 100 is installed is driving at a high speed exceeding the second reference speed, it quickly passes by pedestrians, parked vehicles, or vehicles traveling at low speeds, so the first display 110 and the second display 120 There is a problem that it is difficult to identify video content output from ). Accordingly, when the control unit 130 determines that the vehicle is in a high-speed driving state exceeding the second reference speed, the control unit 130 may control the first display 110 and the second display 110 to output image content.

In some other embodiments, the control unit 130 may control the first display 110 and the second display 120 so that neither video content nor image content is output when the vehicle 1 is in a high-speed driving state. . Through this, the control unit 130 controls the first display 110 and the second display 120 to not provide video content and image content in an environment where it is difficult to identify video content and image content, thereby outputting content. There is an advantage in that power consumption can be reduced.

When it is determined that the vehicle 1 is in a driving state, the control unit 130 controls the video content and image content output from the first display 110 and the second display 120 based on the speed at which the vehicle 1 is traveling. The size can be adjusted.

In some embodiments, when the speed of the vehicle 1 exceeds the reference speed, the control unit 130 controls at least a portion of the video content and image content output from the first display 110 and the second display 120. You can control the output to be enlarged. Here, the reference speed may be a second reference speed for determining that the vehicle 1 is in a high-speed driving state, but is not limited thereto, and may be a new reference speed value arbitrarily set according to the manager using the content output device 100. .

When the vehicle 1 is driven at a high speed exceeding a certain speed, it may be difficult for drivers or passers-by riding in the parked or stopped vehicle to properly identify the video content and image content output from the content output device 100.

Accordingly, when the speed of the vehicle 1 exceeds the reference speed, the control unit 130 enlarges and outputs some areas of the video content and image content output from the first display 110 and the second display 120. By controlling the first display 110 and the second display 120, the identification ability of content output from the first display 110 and the second display 120 can be increased. Here, some areas may be key points (important points) set for each of the plurality of contents, and when the speed of the vehicle 1 exceeds the standard speed, the control unit 130 enlarges the key points each set for the plurality of contents. You can print it out.

In some embodiments, the controller 130 may set the degree to which video content and image content are enlarged according to the speed of the vehicle 1. For example, the control unit 130 may divide the stages of the high-speed driving state according to the speed of the vehicle 1, and set the degree of enlargement to be different depending on the divided stages of the high-speed driving state. For example, when the vehicle 1 is traveling at 70 km/h, the control unit 130 can enlarge the image content output from the first display 110 and the second display 120 by two times, and the vehicle 1 ) is driving at 90 km/h, the control unit 130 can enlarge the image content output from the first display 110 and the second display 120 by three times.

In some embodiments, the controller 130 may set the degree to which video content and image content output from the first display 110 and the second display 120 are enlarged according to the lane in which the vehicle 1 is driving. For example, the control unit 130 may enlarge the video content and image content by 2 times when the vehicle 1 is driving on a lane not adjacent to the sidewalk, and may enlarge the video content and image content by 2 times when the vehicle 1 is driving on a lane not adjacent to the sidewalk. In this case, video content and image content can be enlarged three times.

In some other embodiments, the content output device 100 stores content including a logo and text having a size corresponding to the screen size of the first display 110 and the second display 120 in the content storage. You can save it. When the speed of the vehicle 1 exceeds the second reference speed, the control unit 130 outputs content including the logo and text stored in the content storage unit, allowing people to use the content output device 100. Through this, you can easily identify the output content. However, it is not limited to this, and any method that can increase the identification of content output from the content output device 100 can be applied.

In some embodiments, the content output device 100 is provided on the sidewalk side and the roadway side, respectively, and an analog content providing unit (not shown) formed in a shape that covers the first display 110 and the second display 120. ) may further be included.

The analog content provider may post analog content according to a control signal from the control unit 130. Here, analog content refers to content in the form of paper printed through a printing device. If the ambient illuminance of the content output device 100 exceeds the reference value and it is difficult to properly identify video content and image content output through the first display 110 and the second display 120, the control unit 130 operates, By controlling the analog content provider to post analog content, the identification of content output from the content output device 100 can be increased. Hereinafter, with reference to FIG. 6, a method of outputting content using the content output device 100 according to some embodiments will be described.
