Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital signage systems are limited to two-dimensional information display, reducing their applicability and immersion level, especially as available display areas increase.
Innovation Solution
A digital signage system comprising multiple display devices with a server that includes a communication unit, sensor unit, and controller to transmit and control signage content, allowing for stereoscopic content display by overlapping display areas and adjusting image display time intervals based on movement data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display areas are overlapped to create stereoscopic content, then immersion level and depth perception are improved, but device complexity and control difficulty increase
Solution Approach 1:
The patent merges multiple display devices into an integrated digital signage system with overlapping display areas. The server combines signage content data from multiple sources and controls multiple display devices to work together, creating a unified stereoscopic display system that enhances immersion while managing complexity through centralized control.
Solution Approach 2:
The server acts as an intermediary between content sources and display devices. It receives signage content data, processes it, and transmits controlled data to display devices. The sensor unit also serves as an intermediary by detecting movement and providing feedback data to the server, enabling automatic adaptation without direct complex interactions between display devices.
2Adaptability or versatility
If signage content is controlled in response to movement events, then adaptability and user experience are improved, but measurement precision and control accuracy requirements increase
Solution Approach 1:
The sensor unit provides feedback about movement of display devices or mounting structures to the server. This feedback mechanism enables the system to detect changes in position, orientation, or movement status and automatically adjust signage content display accordingly, improving adaptability while using simple threshold-based detection to manage precision requirements.
Solution Approach 2:
The system performs self-adjustment based on sensor data without requiring manual intervention. When the sensor detects movement exceeding a threshold, the server automatically modifies the display configuration or content presentation, enabling the system to adapt to environmental changes autonomously.
3Area of stationary object
If multiple display devices are used to increase available area, then information display capacity is improved, but applicability and effective utilization are reduced due to two-dimensional listing limitations
Solution Approach 1:
The patent transitions from two-dimensional horizontal listing of display devices to three-dimensional spatial arrangement with overlapping display areas. By utilizing depth perception and spatial layering, the system creates stereoscopic signage content that effectively uses the available display area while significantly improving applicability and user engagement.
Data Source
AI summary
A digital signage system and a data processing method in the same are disclosed. The digital signage system comprises a plurality of display devices displaying a signage content; and a server including a communication unit for transmitting signage content data to each display device, a sensor unit for sensing movement of the plurality of display devices, and a controller for controlling the display devices of which display areas are overlapped, differently from each other on the basis of the sensed movement data of the display devices, if display areas of at least two of the plurality of display devices are overlapped with each other at a predetermined threshold value or more.
