Vehicle Data Glasses Activation Using a Dark Viewing Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewing image or video information on augmented reality data glasses is hindered by the need for a dark viewing background, which is not consistently available in vehicle environments, requiring users to search for and maintain focus on dark surfaces to avoid distractions.
Innovation Solution
A method for operating data glasses that involves monitoring and automatically starting/stopping media presentation based on the position of a dark presentation surface, such as a sun visor, using an interior camera for gesture recognition to transmit start/stop information and display media information in a contact-analog manner tied to the vehicle coordinate system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If media information is displayed in data glasses with dark pixels for transparent presentation, then the augmented perception of environment objects is enabled, but the user must search for and maintain focus on dark background surfaces to avoid distractions
Solution Approach 1:
The system proactively detects when a dark presentation surface (such as a sun visor) is brought into the vehicle interior and automatically initiates media information display in the data glasses before the user needs to view it. This preliminary detection and automatic activation eliminates the need for users to manually search for dark backgrounds or continuously interact with the system to maintain display
Solution Approach 2:
The display system serves itself by automatically detecting the presence of dark presentation surfaces through camera monitoring and autonomously controlling the media information display in the data glasses. The system monitors the vehicle interior, identifies suitable dark surfaces, and manages the display state without requiring continuous user intervention, making the system self-regulating based on environmental conditions
2Ease of operation
If automatic detection of presentation surface position is implemented, then user interaction is reduced, but system complexity increases
Solution Approach 1:
The interior camera system performs multiple functions: it monitors for dark presentation surfaces, tracks user head pose and gaze direction, and provides environmental context for media display. By making the camera system multi-functional, the patent avoids adding dedicated sensors or detection devices, thereby reducing overall system complexity while achieving automatic presentation surface detection
Solution Approach 2:
The system continuously monitors the vehicle interior through the camera, detects when dark presentation surfaces enter or leave the field of view, and automatically adjusts the media information display state accordingly. This closed-loop feedback mechanism enables automatic operation without complex manual controls while maintaining simple user interaction through natural surface manipulation
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
Enables convenient and distraction-free viewing of image or video information by automatically initiating media presentation when a dark background surface is detected and stopping it when not in use, improving user experience by eliminating the need for continuous user interaction.
Implementation Method 1
an interior camera of the vehicle captures the interior, including the head of the wearer of the data glasses, and either the pose of the head is determined by evaluating the camera image using vision tracking methods
Implementation Method 2
The display surfaces may correspond to reflection surfaces that direct images into the eye of the wearer of the data glasses
Implementation Method 3
The viewing openings in the data glasses are transparent, such that it is also possible to perceive the real environment in the usual way through the display surfaces of the data glasses
Data Source
AI summary
A display system is operated with an assistance system tied to the vehicle and data glasses in a vehicle. It is monitored whether a presentation surface has been brought from a stowed position into a position of use in which the presentation surface faces the data glasses. The presentation surface is a dark or black unstructured surface. If it is recognized that the presentation surface has been brought into the position of use, start information from the assistance system is transmitted to the data glasses. Media information in the data glasses is automatically started and displayed depending on the start information.
