Smart Glasses Vehicle Location Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for notifying a driver of a parked vehicle's location, such as using smart keys that turn on headlights and produce sound, are ineffective in crowded parking lots during the day due to visibility and noise issues.
Innovation Solution
A system that uses a smart key recognizer, GPS, and wireless communication to transmit the vehicle's location information to smart glasses worn by the driver, providing visual guidance through augmented reality displays, even in obstructed views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If headlights are turned on to notify driver of vehicle location, then visual notification is provided, but headlights are not visible well in daytime and may be hidden by other vehicles
Solution Approach 1:
The patent introduces a smart device as an intermediary carrier that receives location information from the vehicle and displays it through a camera viewfinder. This mediator transfers the notification function from the vehicle's headlights to the driver's smartphone, where the location can be displayed as an overlay on the camera feed, making it visible regardless of ambient light conditions or obstructing vehicles.
Solution Approach 2:
The patent replaces the mechanical/optical notification system (headlights) with an electronic display system using a smart device's screen and camera. Instead of relying on physical light emission that can be obscured, the system uses digital image processing and display to show vehicle location, substituting a mechanical notification method with an electronic one that is not subject to the same environmental limitations.
2Object-generated harmful factors
If sound output is used to notify driver of vehicle location, then acoustic notification is provided, but sound is difficult to hear due to surrounding noises
Solution Approach 1:
The smart device serves as an intermediary that converts acoustic notifications into visual notifications displayed on the screen. The vehicle's acoustic signal is received and re-presented as a visual indicator overlaid on the camera viewfinder, allowing the driver to see the vehicle location without relying on hearing sound through noisy environments.
Solution Approach 2:
The patent substitutes the acoustic notification system with a visual display system. Instead of using sound waves that compete with surrounding noises, the system uses the smart device's display screen to present location information visually, replacing a mechanical acoustic field with an electronic visual field that is not affected by ambient noise levels.
3Extent of automation
If smart key recognition system is implemented, then automated vehicle location notification is provided, but device complexity increases
Solution Approach 1:
The patent leverages the universal functionality of a smart device that the driver already possesses and uses for other purposes. By utilizing the existing camera, display, and processing capabilities of a common smartphone or smart glasses, the system avoids requiring a dedicated complex notification device. The multi-functional smart device handles recognition, processing, and display tasks that would otherwise require separate specialized components.
Data Source
AI summary
A method for providing a current location of a vehicle includes detecting and determining whether a smart key approaches the vehicle. Identification information of the smart key is received from the detected smart key. Information related to the current location is transmitted to an external device upon recognizing the inherent identification information to provide guidance to the current location of the vehicle through the external device.
