Vehicle Projection Orientation Correction for Navigation Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often face difficulties in navigating to their destination after exiting a vehicle, as the location may be unfamiliar and directions may not be clear, especially when there is a significant distance between the vehicle and the destination.
Innovation Solution
A projection system equipped on a vehicle projects an image onto the ground nearby, detecting the user's position and point of view to automatically adjust the orientation of the image, ensuring that navigation information, such as a map and directions, is easily readable by the user upon exiting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user parks the vehicle at a location away from the destination, then the vehicle can be conveniently parked, but the walking distance from the vehicle to the destination increases
Solution Approach 1:
The system projects directional information onto the ground before the user begins walking, providing advance guidance on the optimal walking path from the parking location to the destination. This preliminary action helps the user navigate efficiently despite the distance
Solution Approach 2:
The projected image on the ground acts as an intermediary between the vehicle and destination, providing visual directional cues that guide the user through the walking path, making the journey despite the distance more manageable
2Productivity
If the user is dropped off at an unfamiliar location, then the vehicle can access the destination area, but the user's ability to navigate to the destination decreases
Solution Approach 1:
The system provides self-service navigation by automatically detecting the user's position and projecting directional information onto the ground, allowing the user to navigate independently without external assistance or complex interface interactions
Solution Approach 2:
The system replaces traditional mechanical navigation interfaces (screens, buttons, physical maps) with optical projection directly onto the ground, making navigation information immediately visible and intuitive in the user's field of view
3Device complexity
If the projected image orientation is fixed, then the projection system is simpler, but the readability of navigation information for users at different positions decreases
Solution Approach 1:
The system dynamically adjusts the orientation of the projected image based on the detected user position and viewpoint, ensuring that navigation information remains readable and correctly oriented regardless of where the user stands relative to the vehicle
Solution Approach 2:
The system uses camera detection to obtain feedback on user position and viewpoint, then automatically adjusts the projection orientation accordingly, creating a closed-loop system that maintains optimal readability
4Adaptability or versatility
If multiple projection devices are equipped on the vehicle, then navigation information can be provided to users at various positions, but the device complexity increases
Solution Approach 1:
Each projection device is designed to be multi-functional, capable of projecting images at multiple orientations and positions. The system can use a single device to serve multiple user positions by adjusting projection parameters, reducing the need for multiple specialized devices

AI summary
A method includes: projecting, using a projection device equipped on a vehicle, an image onto ground nearby the vehicle; detecting a position or a point of view of a user; and rotating the projected image or at least one object within the projected image based on the detected position or point of view of the user. The projected image or the at least one object within the projected image is rotated such that the projected image or the at least one object within the projected image is oriented to face the user.
