Cellular Position Envelope for Driver Passenger Texting Distinction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions fail to effectively prevent text messaging while driving without requiring changes to existing cell phones, cellular infrastructure, or vehicles, and do not adequately differentiate between drivers and passengers, particularly in public transportation scenarios, leading to safety risks due to the addictive nature of texting.
Innovation Solution
A system that uses cellular service providers to determine the position and velocity of cell phones, disabling texting capabilities for moving vehicles unless the user is a passenger on public transportation or in a carpool, by establishing a 'position envelope' that distinguishes between drivers and passengers, allowing passengers to text while preventing drivers from doing so, without altering existing phone or infrastructure hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If text messaging is banned by law, then safety is improved, but compliance is poor because people ignore the laws
Solution Approach 1:
The system provides real-time feedback to drivers by detecting texting behavior and sending warnings to their phones when texting is detected, creating a self-enforcing mechanism that improves compliance without requiring manual law enforcement
Solution Approach 2:
The system enables self-monitoring and self-regulation by automatically detecting texting behavior and notifying the driver, allowing individuals to self-correct their behavior without external intervention
2Reliability
If text messaging is disabled for all moving vehicles, then driver safety is improved, but passenger convenience deteriorates
Solution Approach 1:
The system applies different rules to different locations within the vehicle by detecting whether the phone is in the driver's position or passenger position, allowing texting to be blocked for drivers while permitting it for passengers
Solution Approach 2:
The system segments the vehicle occupancy into driver and passenger zones, applying selective texting restrictions based on the detected position of the phone and the user's role
3Ease of manufacture
If existing cell phones and infrastructure are used without modification, then deployment cost is reduced, but functionality is limited
Solution Approach 1:
The system makes existing cellular infrastructure universal by enabling it to perform both traditional communication functions and new safety monitoring functions without requiring hardware modifications to phones or towers
Solution Approach 2:
The system introduces a software intermediary layer between the existing cellular infrastructure and the texting function, enabling enhanced capabilities through software rather than hardware modifications

AI summary
A system and method are described to track and warn a person suspected of texting while driving a moving vehicle. The position and speed of a user's cell phone are compared with those of other cell phone users in the vicinity. If the position and speed of a phone track that of one or more neighboring phones, it is assumed that a user may under certain conditions be texting while driving. For circumstances where persons suspected to be in the same vehicle utilize different service providers, parameters such as for instance cell phone position, velocity, and direction of travel are time stamped and then compared. Cell phone users who are determined likely to be texting while driving based on the disclosed methods may be warned without disabling their texting capability.
