Vehicle Data Glasses Seat Assignment and Driver Distraction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data glasses can distract drivers while operating a vehicle, posing a risk to traffic safety due to their ability to display messages, graphics, or videos in the driver's central field of vision, and existing solutions fail to differentiate between driver and passenger usage effectively.
Innovation Solution
A device for a vehicle that uses detection means, transmitting and receiving devices, and electronic computing means to recognize seat occupancy and movement patterns of data glasses, determining if the wearer is the driver, and adapting the data glasses' functionality to prevent distracting content from being displayed in the driver's central vision by correlating seat occupancy with data glasses' movement data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data glasses display messages, graphics or videos in the driver's central field of vision, then the user experience and information accessibility are improved, but the driver's attention is distracted from the driving task and road safety is endangered
Solution Approach 1:
The patent applies local quality by differentiating the display functionality based on the user's location. The data glasses display full-content information (messages, graphics, videos) when the user is identified as a passenger, but restrict displays to only trip-relevant information (navigation, speed, warnings) when the user is identified as the driver. This spatial differentiation of display content quality resolves the contradiction by providing appropriate information accessibility without causing driver distraction.
2Adaptability or versatility
If data glasses are used by both driver and passenger without differentiation, then the device versatility is maintained, but the driver's view of the road can be obstructed and traffic safety is endangered
Solution Approach 1:
The patent implements dynamics by making the data glasses' display functionality adaptive rather than static. The system dynamically adjusts the display behavior based on real-time detection of whether the wearer is the driver or passenger. The data glasses automatically switch between two operational modes: full functionality for passengers and restricted functionality for drivers. This dynamic adaptation maintains device versatility for different users while ensuring traffic safety by preventing road view obstruction for the driver.
3Loss of information
If the data glasses display content in the central field of vision, then the information display capability is improved, but the driver's view of the road is obstructed
Solution Approach 1:
The patent applies local quality by implementing location-based content restriction. When the driver is detected, the system restricts display content to only essential trip information that does not obstruct the road view, such as navigation directions, current speed, and safety warnings. Non-essential content like social media messages, entertainment videos, and graphics are suppressed. This selective content quality adjustment maintains necessary information display capability while eliminating road view obstruction for the driver.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances traffic safety by ensuring that data glasses used by drivers are configured to display only trip-relevant information, reducing the risk of distraction and ensuring the driver's attention remains focused on the road.
Implementation Method 1
data glasses have motion sensors (in particular acceleration sensors). The outputs of the motion sensors are examined to determine whether a movement of the data glasses can be detected, which suggests that the wearer of the data glasses is sitting in a vehicle seat
