3D HUD Graphical Overlay Personalization via Cloud Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current three-dimensional heads-up display (HUD) systems for vehicles lack the ability to provide dynamic and personalized graphical overlays for nearby and distant vehicles, limiting driver interaction and communication.
Innovation Solution
A 3D overlay application that wirelessly retrieves and displays graphical information, such as digital bumper stickers and badges of accomplishment, associated with other vehicles from a cloud server, allowing drivers to personalize their vehicle's appearance and communicate with other drivers through a 3D HUD, which follows vehicle positions and updates overlays in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If graphical overlays are displayed for nearby and distant vehicles in a 3D HUD, then driver interaction and communication are enhanced, but device complexity increases due to wireless retrieval and real-time updating mechanisms
Solution Approach 1:
The patent introduces a cloud server as an intermediary to store and manage graphical overlay data for multiple vehicles. Instead of each vehicle directly communicating with every other vehicle (which would create complex peer-to-peer relationships), the cloud server acts as a central mediator that receives, stores, and distributes overlay information, significantly reducing system complexity while enabling enhanced driver interaction.
Solution Approach 2:
The 3D HUD system is designed to display multiple types of graphical overlays simultaneously (digital bumper stickers, badges of accomplishment, vehicle information) for both nearby and distant vehicles. This multi-functional capability allows a single system to handle diverse communication needs, enhancing versatility without requiring separate systems for each function.
2Loss of information
If the 3D HUD follows vehicle positions and updates overlays in real-time, then communication awareness is improved, but energy consumption increases due to continuous wireless communication and rendering
Solution Approach 1:
The system updates graphical overlays at periodic intervals rather than continuously. The 3D overlay application retrieves and displays overlay information at scheduled update cycles, which maintains communication awareness by regularly refreshing vehicle position and overlay data while significantly reducing energy consumption compared to continuous real-time updates.
3Adaptability or versatility
If digital bumper stickers and badges of accomplishment are displayed, then vehicle personalization is enhanced, but information overload may distract the driver
Solution Approach 1:
The patent applies different visual characteristics to different types of graphical overlays based on their importance and location. Digital bumper stickers and badges of accomplishment are displayed with distinct visual properties (such as different colors, sizes, or positions) that allow drivers to quickly distinguish between various types of information. This localized differentiation helps prevent information overload by making the display more scannable and less uniform, thereby reducing driver distraction while maintaining personalization.

AI summary
The disclosure includes a system and method for wireless data sharing between a mobile client device and a three-dimensional heads-up display unit. A system may include a three-dimensional heads-up display unit (“3D HUD”) installed in a vehicle. The system may include a memory storing instructions that, when executed, cause the system to: establish a peer-to-peer video stream between a mobile client device and the vehicle; generate live video data for providing a video stream for causing a screen of the mobile client device to display visual content of the 3D HUD that includes substantially live images depicting what the driver of the vehicle sees when looking at the 3D HUD; and stream the live video data to the mobile client device to cause the screen of the mobile client device to display the video stream that depicts what the driver of the vehicle sees when looking at the 3D HUD.
