Communication Apparatus Context-Aware Attention Alerting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for preventing pedestrian accidents due to smartphone use do not adequately consider the user's surroundings and may cause inconvenience or increase radio wave congestion.
Innovation Solution
A communication apparatus that estimates movement and operation states using sensors and manages terminal information transmission to display attention-calling information only when necessary, reducing unnecessary radio wave transmission and improving user awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal information is transmitted frequently to ensure user safety, then user awareness of dangers is improved, but radio wave congestion increases and battery consumption rises
Solution Approach 1:
The system dynamically changes transmission parameters (timing, frequency, content) based on detected movement state and operation state. When user is stationary and not operating the terminal, transmission frequency increases to ensure safety awareness. When user is moving or actively using the terminal, transmission frequency decreases to conserve battery and reduce radio wave congestion.
2Reliability
If terminal information is transmitted to all users regardless of context, then safety awareness is improved, but radio wave congestion occurs and processing load increases
Solution Approach 1:
The system applies different transmission strategies to different user contexts. Instead of uniform transmission to all users, it selectively transmits information based on local conditions (movement state and operation state of each user), thereby reducing overall radio wave congestion while maintaining safety awareness where needed.
3Reliability
If programs or screens are restricted based on user activity, then safety is improved, but user convenience deteriorates when restriction is unnecessary
Solution Approach 1:
The system dynamically adjusts terminal operation restrictions based on real-time detection of movement state and operation state. Restrictions are applied only when both conditions indicate potential danger (e.g., stationary state combined with terminal operation), while allowing normal operation when conditions indicate safety (e.g., active movement or appropriate operational context), thereby maintaining user convenience when restrictions are unnecessary.

AI summary
A technique controlling transmission and display of terminal information in accordance with a movement state and an operation state. A communication unit transmits terminal information including at least movement information of a communication apparatus to another communication apparatus, and receives other terminal information including at least movement information of the other communication apparatus from the other communication apparatus. A terminal information controller controls transmission of the terminal information from the communication unit to the other communication apparatus based on the movement state estimated by a movement-state estimation unit and the operation state managed by an operation-state management unit, and when it is determined on the basis of the terminal information and the other terminal information received by communication unit that an attention calling state has occurred, controls display information that causes a display to display attention calling information on the basis of the movement state and the operation state.
