Projected Vehicle Interface for External User Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interaction technologies primarily focus on in-vehicle user interfaces during driving, lacking convenient and safe remote control options for users outside the vehicle.
Innovation Solution
A projection-based user interface system using cameras and projectors to identify and project vehicle control functions on the ground for users approaching the vehicle, enabling remote control through user-specific interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a projection-based user interface is implemented for external users, then user convenience and safety are improved, but device complexity increases due to additional cameras and projectors
Solution Approach 1:
The projector serves multiple functions: it projects the user interface for external users and can also function as a standard projector for other purposes. The camera system serves dual purposes by capturing both user identification information and user input gestures, reducing the need for separate specialized components.
Solution Approach 2:
The system uses the vehicle's existing camera infrastructure to capture user identification and input information, eliminating the need for separate dedicated sensors. The projector utilizes the vehicle's power and control systems, reducing the need for independent power supplies and control circuits.
2Speed
If user identification and interface projection are performed simultaneously, then interaction speed is improved, but processing time increases
Solution Approach 1:
The system performs user identification processing in advance as users approach the vehicle, so that when users reach the interaction zone, the interface is already prepared and ready for immediate projection. This preliminary processing reduces the perceived interaction delay.
Solution Approach 2:
The system maintains continuous camera monitoring and processing of user presence and gestures, eliminating idle processing time. The projector continuously updates the interface based on real-time user input detection, ensuring seamless interaction without interruptions or delays.

AI summary
A device for providing an interface using a projection includes: a first camera for capturing a vehicle user when an approach of the vehicle user to a vehicle is detected; a projector for projecting an interface, related to at least one vehicle control function, preset based on user identification information; a second camera for capturing an area on which the interface is projected; a memory storing one or more instructions; and a processor for executing the instructions to: acquire the user identification information of the vehicle user using the first camera, recognize a user input to the interface using the second camera, and perform a vehicle control corresponding to the interface when the user input is recognized.
