Context-Aware Information Display System for Mobile Eye Glasses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information display systems fail to accurately provide users with context-specific information without requiring intentional action, as they cannot accurately determine the user's active state based on time, position, and situation.
Innovation Solution
An information display system that includes sensors worn by the user to measure body states, such as indoor-outdoor sensors, GPS, foot pressure sensors, utterance-mastication sensors, and movement measuring sensors, which identify the user's active state and estimate required information for display on a mobile eye glass (MEG) without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the system uses only time and position information to determine user state, then the device complexity is reduced, but the measurement precision and accuracy of user state detection deteriorates
Solution Approach 1:
The system segments the user state detection into multiple independent sensor modules (indoor-outdoor sensor, GPS, foot pressure sensor, utterance-mastication sensor, movement measuring sensor), each responsible for detecting specific aspects of user state. This segmentation allows the system to achieve high measurement precision through specialized sensors while managing complexity through modular architecture.
Solution Approach 2:
The system employs a multi-functional sensor suite where each sensor serves multiple purposes: GPS determines both position and movement speed, foot pressure sensors detect both walking state and pace, utterance-mastication sensors identify both speech and eating states. This multi-functionality enables comprehensive user state detection without proportionally increasing system complexity.
2Ease of operation
If the system provides information proactively without user action, then the ease of operation is improved, but the reliability of information relevance deteriorates
Solution Approach 1:
The system continuously monitors multiple sensor inputs (position, movement speed, indoor-outdoor status, speech patterns, eating states) and uses this feedback to dynamically adjust information provision. The active state identifying section processes sensor feedback in real-time to determine user state, ensuring information relevance while maintaining ease of operation through proactive delivery.
Solution Approach 2:
The system performs self-service by automatically determining user state and selecting appropriate information without requiring user initiation. The active state identifying section and information selecting section work autonomously to interpret sensor data and deliver relevant information, combining ease of operation with high relevance through intelligent self-adjustment.
3Measurement precision
If the system uses multiple sensors to detect user state, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The sensor system is segmented into functionally independent modules: indoor-outdoor sensor for environment detection, GPS for position and movement, foot pressure sensor for gait analysis, utterance-mastication sensor for speech/eating detection, and movement measuring sensor for physical activity. This segmentation enables high measurement precision through specialized sensors while managing complexity through modular design and dedicated processing for each sensor type.

AI summary
An information display system includes a sensor which measures a state of each part of a body of a user, an active state identifying section which identifies an active state of the user based on a measurement result, an information estimating section which estimates information required by the user based on the active state identified by the active state identifying section, a database which stores at least the information required by the user, an information selecting section which selects the information required by the user from a plurality of information stored in the database, and an information display section which displays the information required by the user selected by the information selecting section.
