Mobile Device Acoustic Interface for IC Access Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require a computer with a display function at electronic time recorders, ticket gates, and IC card readers to acquire and display information from servers, limiting their functionality without external display devices.
Innovation Solution
A mobile device inputs sound effects from an access device upon IC module access and displays provision information on a connected display device, enabling users to receive location-specific service information without needing a computer with a display function on the external device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a computer with a display function is installed at electronic time recorders, ticket gates, and IC card readers to display information, then information display capability is improved, but device complexity and hardware requirements increase
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the access device and the user. The mobile terminal receives sound effects from the access device, processes them, and displays information on its own display screen. This mediator approach allows information display without requiring the access device itself to have display capabilities, thus resolving the contradiction between information display capability and device complexity
Solution Approach 2:
The patent replaces the traditional mechanical/electronic display system (requiring physical display hardware at the access device) with an acoustic system. The access device outputs sound effects containing encoded information, and the mobile terminal's microphone captures these sounds for processing and display. This substitution eliminates the need for physical display hardware at the access device while maintaining information display functionality
2Ease of operation
If a computer with a display function is installed at access devices to provide service information, then user convenience is improved, but ease of operation and system simplicity deteriorate
Solution Approach 1:
The patent enables the user's own mobile terminal to serve as the information display device. The mobile terminal uses its built-in microphone to capture sound effects from the access device, processes the acoustic information, and displays service information on its screen. This self-service approach allows users to access information conveniently using their personal devices without requiring the access device to be equipped with display hardware
Solution Approach 2:
The patent makes the mobile terminal a multi-functional device that serves both as the access medium (containing the IC module for authentication) and as the information display device. This universal approach allows a single device to fulfill multiple functions, eliminating the need for separate display hardware at the access device while maintaining user convenience

AI summary
A mobile terminal inputs a sound effect output from a communication device through a microphone in response to completion of access to an IC module, and determines whether a sound pattern of the input sound effect indicates a preset sound pattern. When it is determined that the sound pattern of the input sound effect indicates the preset sound pattern, the mobile terminal displays provision information on a location where the communication device exists, on the display device that is display-controlled by the mobile terminal.
