Sound Signal-Based Local Interactive Platform for Smart Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interactive services on smart terminals require user manipulation to access content, limiting accessibility to multi-formatted information when a dedicated application is installed, and do not provide personalized content based on location or time spent in specific areas.
Innovation Solution
A sound signal-based local interactive platform system that includes a wired/wireless AP outputting a unique sound signal, a smart terminal detecting and transmitting this signal to a location server, and subsequently receiving multi-formatted content from a content server, which also accumulates time spent in the area as a 'time coin' for benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated application is installed in smart terminals for interactive services, then service functionality is improved, but user manipulation complexity increases and accessibility decreases
Solution Approach 1:
The system enables self-service by automatically detecting sound signals in the environment and triggering corresponding content delivery without requiring user manipulation. The smart terminal autonomously identifies the sound signal pattern, retrieves associated content from the server, and outputs it, making the service accessible to all users regardless of their technical proficiency
Solution Approach 2:
Content is pre-mapped and stored on the server associated with specific sound signal patterns before users arrive. When a user enters an area with a particular sound signal, the corresponding content is already prepared and can be immediately delivered, eliminating the need for users to search or select content manually
2Ease of operation
If sound signal detection is implemented for automatic content delivery, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A server acts as an intermediary between the sound signal detection and content output functions. The server stores the mapping between sound signal patterns and content, handles the retrieval process, and manages content delivery to multiple terminals. This centralizes the complexity on the server side while keeping the smart terminal relatively simple
Solution Approach 2:
The server provides multiple functions including sound signal pattern storage, content storage, pattern-content mapping, and content delivery through a single system. This multi-functional approach consolidates what could be separate complex components into one unified platform, reducing overall system complexity
3Loss of information
If multi-formatted content information is transmitted in real-time, then information richness is improved, but data transmission volume increases
Solution Approach 1:
All multi-formatted content is pre-loaded and stored on the server in various formats (audio, video, text) before users arrive. When a user detects a sound signal, the server retrieves the already-prepared content locally stored on its servers, avoiding the need to stream or generate content in real-time, thus reducing transmission volume while maintaining information richness

AI summary
The present invention relates to a technology for providing a place/time-based local interactive service, which provides multi-formatted content information to a user moving while carrying a smart terminal having a dedicated application installed therein. In particular, when moving into a place where a specific wired/wireless AP is installed, a user who carries a smart terminal with a dedicated application activated therein can receive multi-formatted content information previously mapped with the place using a place/time, without a separate manipulation of the smart terminal. According to the present invention, time periods during which the user carrying the smart terminal stays at the place where the specific wired/wireless AP is installed are accumulated and managed using time coins, and the user is then given a benefit according to the accumulated time periods.
