Interactive Vehicle Window Display System for External Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle infotainment and navigation systems require significant user interaction time, leading to driver distraction and increased travel time, as they are typically mounted in the dashboard, limiting display size and functionality, and requiring users to be inside the vehicle for operation.
Innovation Solution
An interactive vehicle window display system that includes an interactive display subsystem, control subsystem, user identification subsystem, and user location subsystem, allowing users to interact with vehicle systems through a window display using gestures, voice commands, and a key fob, providing access to personalized information and vehicle controls from outside the vehicle, thereby reducing driver distraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display is mounted in the dashboard, then the control elements are accessible to the driver, but the display size is limited and driver distraction increases
Solution Approach 1:
The patent introduces an external display device (smartphone, tablet, or portable display) as an intermediary between the driver and the vehicle's infotainment system. This intermediary allows the driver to access control elements and information outside the vehicle, eliminating the need to interact with dashboard-mounted controls during driving, thereby reducing distraction while maintaining full system accessibility.
Solution Approach 2:
The system moves the display interface from the traditional two-dimensional dashboard plane to an external portable device that can be positioned in three-dimensional space outside the vehicle cabin. This dimensional shift allows the display to be located where it does not obstruct the driver's view or require visual attention inside the cabin, effectively separating the control interface from the driving environment.
2Adaptability or versatility
If the user interacts with the system inside the vehicle, then all control functions are accessible, but travel time increases due to required user presence
Solution Approach 1:
The system enables users to perform preliminary actions (accessing infotainment, navigation, climate control, and other vehicle functions) before entering the vehicle or while approaching it. By allowing pre-configuration of settings and access to information externally, the system eliminates the need for users to spend time interacting with controls after entering the vehicle, thereby reducing total travel time while maintaining full adaptability of control functions.
3Adaptability or versatility
If multiple control options are provided in the dashboard, then system functionality is comprehensive, but driver safety decreases due to distraction
Solution Approach 1:
The portable display acts as a mediator that provides comprehensive system functionality without requiring the driver's direct interaction with dashboard controls. All control options remain accessible through the external device, maintaining full system adaptability while physically separating the control interface from the driving environment, thereby preserving driver safety and operational reliability.

AI summary
A system for a vehicle includes a user identification subsystem operable to detect a user and an interactive display subsystem operable to generate output for display on a vehicle window in response to detection of the user. The system also includes a control subsystem operable to enable a user to control at least one vehicle function through the interactive display subsystem. A method of operating a system for a vehicle includes detecting a user of the vehicle and generating output for display on a vehicle window, the output being visible from outside and/or inside the vehicle in response to detection of the user. The method can also include controlling vehicle function through an interactive display subsystem operable to generate output for display on the vehicle window and executing the instructions using a control subsystem.
