Mobile Terminal Movement Detection and Notification Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing frequency of smartphone use during movement, such as walking or driving, leads to safety concerns due to the distraction of incoming calls and messages, with existing solutions either not effectively restricting passive reactions or causing inconvenience by not distinguishing between different movement speeds accurately.
Innovation Solution
A mobile terminal with a call or texting function that uses GPS to determine movement speed and automatically sets incoming call notifications to non-displayed and silent when moving at speeds up to 20 km/h, ensuring the user is not distracted by incoming calls or messages, and automatically sends a message to the sender indicating inability to take the call.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile terminal displays incoming call notifications and allows user interaction during movement, then communication continuity is maintained, but user safety deteriorates due to distraction during walking or vehicle operation
Solution Approach 1:
The system preemptively detects movement state through GPS and accelerometer data, and before the user can be distracted by incoming calls, it automatically suppresses notification display and blocks interaction. This preliminary detection and suppression prevents the safety issue from occurring in the first place, rather than reacting after distraction has begun
Solution Approach 2:
The system changes the operational parameters of the notification system based on movement state. When movement is detected (speed exceeding threshold), the notification display parameter is changed from 'visible and interactive' to 'suppressed and blocked'. This dynamic parameter adjustment resolves the contradiction by adapting system behavior to environmental conditions
2Reliability
If the mobile terminal suppresses all incoming call notifications during movement, then user safety is improved, but communication responsiveness worsens as users cannot receive or respond to important calls
Solution Approach 1:
The system performs preliminary actions by automatically sending notification messages to the caller indicating the user is in movement and cannot answer. This preliminary communication maintains responsiveness by informing the caller of the situation, while the actual call interaction remains suppressed for safety
Solution Approach 2:
The system introduces an intermediary communication channel (automated notification message) that mediates between the suppressed call notification and the user. This intermediary maintains communication flow by conveying the user's unavailable state to the caller, preventing complete information loss while maintaining safety
3Reliability
If the mobile terminal uses GPS to detect movement for suppressing notifications, then user safety is improved, but measurement precision worsens at low speeds (walking or slow vehicle movement) making it difficult to distinguish between stationary and moving states
Solution Approach 1:
The system merges multiple detection mechanisms - GPS location data and accelerometer data - to compensate for GPS's low-speed detection limitations. The accelerometer provides complementary motion detection capability that remains effective at walking speeds, creating a more reliable combined movement detection system
Solution Approach 2:
The system uses a composite sensing approach combining different sensor types (GPS receiver and accelerometer) with different operational characteristics. GPS provides accurate high-speed detection while accelerometer provides reliable low-speed detection, creating a composite detection system that covers the full speed range effectively
4Loss of information
If the mobile terminal automatically sends notification messages to callers during movement, then communication responsiveness is improved, but device complexity increases due to additional automated communication functions
Solution Approach 1:
The system performs self-service by automatically generating and sending notification messages without requiring user intervention. The automated message conveys the movement state and unavailability to callers, maintaining communication responsiveness while eliminating the need for complex user interfaces or manual actions during movement
Data Source
AI summary
The present invention provides a mobile terminal with a call function or a texting function. The present invention controls the use of a mobile terminal by a manual operation because of an incoming call during movement. Location information indicating movement of a mobile terminal with a call or a message data exchange function is received by a GPS receiver, the distance and the movement speed are determined by using the measurement information of the two locations at every predetermined time, and whether or not the mobile terminal is moving in accordance with the movement speed is determined by a movement determination unit. When it is determined by the movement determination unit that the mobile terminal is moving, the display of incoming call information indicating an incoming call is set to non-displayed on the display unit, and at the same time, a notification sound from a speaker, etc. is invalid.
