Periodic Display Control for Public Safety Device Distraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public-safety officers face distractions while using mobile devices in dangerous situations, such as traffic stops, where they need to remain aware of their surroundings, and existing solutions that limit device usage are not optimal as they prevent access to necessary information.
Innovation Solution
A method and apparatus that allow users to view device content for limited periods, using timers (Tuse and Tblocked) to restrict access during dangerous situations, ensuring the user alternates between focusing on the device and their surroundings, with the device resuming full access when the situation is deemed safe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the device allows continuous viewing of content, then the user can access necessary information, but the user becomes distracted from their surroundings
Solution Approach 1:
The system implements periodic viewing by alternating between active display periods and inactive display periods. During active periods, the user can view content on the device. During inactive periods, the display is turned off or obscured. This periodic action allows the user to access necessary information while periodically refocusing attention on the surrounding environment, thereby resolving the contradiction between information access and distraction.
2Object-affected harmful factors
If the device prevents viewing during dangerous situations, then user distraction is reduced, but the user cannot access necessary information
Solution Approach 1:
The system dynamically adjusts display accessibility based on the detected situation. When a dangerous situation is detected (e.g., via GPS location, motion sensors, or user input), the system automatically activates periodic viewing mode. When the situation is determined to be safe, the system transitions to continuous viewing mode. This dynamic adaptation allows the device to prevent distraction during dangerous situations while maintaining full information access during safe periods.
3Ease of operation
If the device allows full access to content, then the user can view material continuously, but the user becomes unaware of their surroundings
Solution Approach 1:
The system incorporates feedback mechanisms through various sensors (GPS, accelerometer, gyroscope) and user inputs to continuously monitor the situation. Based on this feedback, the system automatically adjusts between periodic and continuous viewing modes. This feedback loop ensures that device accessibility is maintained when safe, while automatically reducing accessibility when the situation indicates potential danger, thereby maintaining both ease of operation and situational awareness.

AI summary
A method and apparatus for reducing user distraction is provided herein. During operation a user device will show content for limited periods of time during a context where the user is not to be distracted. So for example, a police officer driving may only be able to look at the screen of his device for a first period of time (e.g., 3 seconds). After that period of time, the device will prevent further viewing (preferably by turning off the screen). After a second period of time (e.g., 10 seconds), the device will again allow the officer to look at the screen for the first period of time. When the device has determined that user distraction does not need to be prevented, the device will allow full access to the user.
