Vehicle Window Projection Interface for Exterior User Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems are limited in their ability to provide exterior-facing information to authorized users without requiring direct interaction with the vehicle's interior controls or smartphone, and there is a need for a more intuitive and secure way to control vehicle functions from outside the vehicle.
Innovation Solution
A vehicular projection display system that projects images onto the inner side of a vehicle window, allowing authorized users to view and control vehicle functions through gestures or inputs at the window panel, using a projector device and optional coatings to enhance visibility, and integrates with smartphone control for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display is located at the inner side of a window panel for exterior viewing, then exterior users can view information without interior interaction, but the display visibility and control capability are limited
Solution Approach 1:
A projector device is introduced as an intermediary to project images onto the window panel's inner side, enabling exterior viewing without requiring interior display components. This mediator allows information transmission from the interior control system to exterior users through the window surface.
Solution Approach 2:
The display interface is moved from the traditional interior dashboard dimension to the window panel surface dimension, allowing exterior users to interact with vehicle functions by touching or gesturing at the window surface rather than requiring interior panel interaction.
2Adaptability or versatility
If a projector device projects images at the window panel for exterior viewing, then exterior users can access vehicle information, but the system complexity increases
Solution Approach 1:
The window panel serves multiple functions: it acts as both a structural vehicle component and a projection display surface. The projector device is integrated into the existing vehicle architecture, utilizing the window panel's existing structure rather than requiring separate dedicated display hardware for exterior viewing.
3Ease of operation
If gesture recognition is implemented at the window panel, then exterior user control is enhanced, but the detection precision and reliability may be affected
Solution Approach 1:
The system incorporates feedback mechanisms where the projector device and control system respond to detected gestures by providing visual confirmation on the window panel. This feedback loop allows the system to adjust and refine gesture recognition, improving detection accuracy through iterative validation of user inputs.

AI summary
A vehicular display system includes a projection device disposed within an interior cabin of a vehicle. The projection device is operable to project information toward an inner side of a window panel of the vehicle for viewing of the projected information by a person outside of the vehicle. Responsive at least in part to determination of presence of an authorized user outside of the vehicle and at or near the window panel of the vehicle, the projection device projects information for viewing by the authorized user of the vehicle.
