Vehicle Advertisement Display Dynamic Video Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles traveling alongside or behind each other on roads do not have uniform travel times due to varying turning places, traffic signals, and lane flow differences, leading to incomplete viewing of advertisements displayed as moving images, which hampers the effectiveness of advertising content transmission to viewers.
Innovation Solution
An advertisement display device mounted on vehicles, equipped with a calculation unit to determine visually recognizable time based on driving states, such as stop times at traffic signals, and a display controller to adjust video lengths or switch to still images when necessary, ensuring that advertisements are displayed for the duration viewers can see them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If advertisement is displayed as moving image to enhance advertisement effect, then advertisement effect is improved, but only part of advertisement may be viewed due to non-uniform vehicle travel times
Solution Approach 1:
The advertisement display device dynamically adjusts the video playback speed based on the relative speed between the host vehicle and the observed vehicle. When the relative speed is high (vehicles passing quickly), the video plays faster or switches to still images. When the relative speed is low (vehicles traveling together longer), the video plays at normal speed or completes playback. This dynamic adjustment ensures the advertisement content is fully viewed within the available time window.
Solution Approach 2:
The system continuously monitors the relative speed between vehicles and uses this feedback to control the advertisement playback. The playback speed is adjusted in real-time based on the observed relative speed, ensuring optimal viewing conditions. This feedback mechanism allows the system to adapt to changing traffic conditions and maintain effective advertisement delivery.
2Loss of information
If advertisement video length is extended to transmit complete content, then advertisement content completeness is improved, but viewing time may exceed available visually recognizable time
Solution Approach 1:
The advertisement video playback speed is dynamically adjusted based on the calculated visually recognizable time. The system plays back the video at a speed that ensures complete content delivery within the available time window. If the available time is limited, the video plays faster or switches to key frames/still images, maintaining content completeness while respecting time constraints.
Solution Approach 2:
The system changes the playback speed parameter of the advertisement video based on the relative speed between vehicles. By adjusting this parameter, the system ensures that the advertisement content is delivered completely within the visually recognizable time window, whether that window is short (high relative speed) or long (low relative speed).

AI summary
A control device as an advertisement display device that is mountable on a vehicle includes a calculation unit configured to calculate a time for which an occupant of another vehicle is able to visually recognize a video displayed on a display attached to a host vehicle based on a driving state of the host vehicle, and a display controller configured to display an advertisement edited such that a video time corresponds to the visually recognizable time calculated by the calculation unit on the display.
