Output Control Device for Continuous Content Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital signage technologies fail to continue displaying time-sensitive content to individuals who move away from the initial display device, as the content is excluded from the display target if the viewer moves beyond the device's vicinity.
Innovation Solution
An output control device and system that determine if a person is a specific individual, acquire their position information, and control nearby output devices to continue displaying information if the person moves to a different location, ensuring continuous reproduction of content across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If content is excluded from display when the viewer moves away from the digital signage device, then the device complexity is reduced and energy consumption is lowered, but the continuity of information delivery to the specific person is interrupted
Solution Approach 1:
The system segments the information delivery function across multiple output devices (first output device and second output device) rather than relying on a single device. When a person moves from the vicinity of the first output device to the second, the playback information is transferred to maintain continuous delivery, thus resolving the contradiction between reliability and device complexity.
Solution Approach 2:
The output control device acts as an intermediary that manages the transfer of playback information between multiple output devices. It monitors person movement and coordinates the handover of content playback from the first output device to the second, ensuring continuous information delivery without requiring complex modifications to each individual output device.
2Duration of action of moving object
If multiple output devices are used to track and display content to moving persons, then the continuity of content playback is maintained, but the device complexity and coordination requirements increase
Solution Approach 1:
The patent merges the control functions of multiple output devices into a single output control device that manages all playback operations centrally. This coordination approach maintains continuous content playback across multiple devices while avoiding the complexity of distributed coordination protocols between devices.
Solution Approach 2:
The system implements feedback mechanisms where the output control device monitors the movement status of persons and the playback state of multiple output devices. Based on this feedback, it dynamically adjusts which device plays content and at what stage, ensuring uninterrupted playback while simplifying coordination through centralized decision-making.

AI summary
An output control device includes a determination unit configured to determine whether or not a person is a specific person, a processing unit configured to acquire position information of the person, and an output control unit configured to cause a first output device located in the vicinity of the person to output information according to the person on the basis of personal information about the person determined to be the specific person by the determination unit and the position information acquired by the processing unit, wherein the output control unit is configured to cause a second output device to output the information output by the first output device in continuation with the output of the first output device if the person has moved from the vicinity of the first output device to the vicinity of the second output device.
