Mobile Terminal Notification Prioritization for Driving Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile terminals fail to prioritize and manage notification information effectively while driving, potentially distracting drivers with non-essential messages during critical navigation tasks.
Innovation Solution
A mobile terminal system that prioritizes notification information, delaying or interrupting less critical messages (such as social networking service notifications) to ensure that turn-by-turn navigation and safety-related information are output promptly and without interruption, using a controller to manage output based on predefined priorities and real-time vehicle data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all notification information is output simultaneously to the driver, then the driver receives complete information, but the driver becomes distracted and unsafe due to information overload
Solution Approach 1:
The notification information is segmented into multiple priority levels (first priority for vehicle-related notifications, second priority for terminal-related notifications). The controller separately manages and outputs notifications based on their priority classification, preventing information overload by delivering only the most relevant notifications at any given time.
Solution Approach 2:
The controller performs preliminary classification and priority assignment of notification information before output. By pre-establishing priority levels and managing the output sequence in advance, the system ensures that critical vehicle-related notifications are delivered first, preventing driver distraction from less important notifications.
2Reliability
If critical vehicle notifications are prioritized and output first, then driving safety is improved, but terminal notification delivery may be delayed
Solution Approach 1:
The notification output system is dynamic and adaptive. When the vehicle is in motion, the controller prioritizes vehicle-related notifications and delays terminal notifications. When the vehicle is stationary, the controller can output terminal notifications without delay. This dynamic adjustment optimizes both driving safety and notification delivery timing based on real-time vehicle state.
Solution Approach 2:
The controller periodically checks the vehicle state (moving or stationary) and adjusts notification output accordingly. Terminal notifications are held in a queue and output periodically when appropriate conditions are met, ensuring that critical vehicle notifications are never delayed while terminal notifications are delivered as soon as safe conditions allow.
3Adaptability or versatility
If multiple notification types are output without prioritization, then all information is delivered, but the notification management system becomes complex
Solution Approach 1:
Different notification types are assigned different priority levels based on their local characteristics and importance. Vehicle-related notifications (turn-by-turn, speed limits, POIs) are assigned first priority, while terminal-related notifications (calls, messages, SNS) are assigned second priority. This localized quality assignment simplifies management by creating clear, distinct categories rather than requiring complex individual management of each notification type.

AI summary
Disclosed are a mobile terminal capable of allowing a driver to drive a vehicle safely, by providing notification information related to the vehicle, and notification information received from the mobile terminal according to priorities, and a method of controlling the same. The mobile terminal includes: a communication unit; an output unit configured to output road guidance information; and a controller configured to detect first notification information related to a vehicle, to receive second notification information from a mobile terminal through the communication unit, to set priorities of the first and second notification information, and to output the first and second notification information to the output unit according to the set priorities.
