Solution Overview
Problem
Existing digital signage and evacuation guidance systems face challenges in efficiently providing targeted display information to multiple users across various locations, as they lack a systematic approach to identify and respond to individual user positions and preferences.
Innovation Solution
An information processing apparatus and system that uses a network of output devices, gateways, and display devices to identify user positions through unique IDs and acoustic signals, allowing the management server to control display devices to show relevant information based on user location and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a network of output devices and display devices is deployed to provide information to multiple users, then the ability to provide targeted display information to multiple users is improved, but the system complexity increases
Solution Approach 1:
The system divides the information provision task into multiple output devices distributed at different locations, each capable of independently identifying and providing information to users in its coverage area. This segmentation allows the system to handle multiple users simultaneously without requiring a single complex centralized device.
Solution Approach 2:
Each output device is designed to perform multiple functions: emitting acoustic waves for user identification, receiving identification information, determining user positions, and controlling display devices. This multi-functionality reduces the need for separate specialized devices, thereby managing system complexity while maintaining versatility.
2Measurement precision
If user positions are identified through acoustic signals and unique IDs, then the precision of user position identification is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The system uses acoustic waves as an intermediary medium to transmit user identification information from the information terminal to the output device. This intermediary approach enables position identification without requiring direct line-of-sight or complex sensing, simplifying the detection process while maintaining precision.
Solution Approach 2:
The system replaces complex mechanical or visual positioning systems with acoustic signal-based identification. By using sound waves to carry identification information, the system achieves accurate position detection without requiring complex optical sensors, cameras, or mechanical tracking devices.
3Ease of operation
If display information is adapted based on user location and preferences, then the user experience is improved, but the processing requirements and system complexity increase
Solution Approach 1:
The system tailors display information to local user needs and positions, providing customized content to each user based on their location and preferences. This local adaptation enhances user experience without requiring global system reconfiguration, as each output device independently processes and adapts information for its local users.
Solution Approach 2:
The system pre-processes and stores identification information and user preferences in advance, allowing for rapid adaptation of display information when users are identified. This preliminary preparation reduces real-time processing requirements, managing system complexity while maintaining personalized user experience.
