AR-HUD POI Overlay With Engagement Feedback for Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality head-up displays (AR-HUDs) for vehicles do not provide information about points-of-interest (POIs) in the environment surrounding the vehicle to occupants, limiting their environmental awareness.
Innovation Solution
A system that includes a global navigation satellite system (GNSS), a vehicle communication system, a display system, and a vehicle controller, which determines the vehicle's location, transmits this data to a remote server, and displays graphics related to POIs on the windscreen using an AR-HUD system, while tracking occupant engagement metrics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If current AR-HUDs display basic navigational information, then the occupant's forward field of view is maintained, but additional information about points-of-interest is not provided
Solution Approach 1:
The system segments information display by creating separate functional modules: a POI information module that retrieves and processes point-of-interest data, and a display integration module that overlays this information on the windscreen. This segmentation allows POI information to be added without redesigning the entire AR-HUD system.
Solution Approach 2:
The patent introduces an intermediary processing layer between the navigation system and the display system. This intermediary module receives POI data, processes it into appropriate visual formats, and coordinates with the AR-HUD display controller to overlay information seamlessly. The intermediary handles data formatting, positioning calculations, and timing synchronization.
2Loss of information
If more information is displayed to enhance environmental awareness, then occupant awareness is improved, but the risk of diverting attention from the road increases
Solution Approach 1:
The system applies local quality by positioning POI information displays at specific locations on the windscreen that correspond to the actual spatial location of points-of-interest in the external environment. This spatial correspondence allows occupants to naturally associate the displayed information with its real-world location without requiring attention shifts.
Solution Approach 2:
The system implements periodic action by updating POI information displays only when relevant events occur, such as when the vehicle approaches a new point-of-interest or when the occupant's gaze indicates interest. This event-driven update strategy minimizes unnecessary visual changes that could distract the occupant.
3Adaptability or versatility
If engagement metrics are tracked to improve service, then user experience is enhanced, but data processing requirements increase
Solution Approach 1:
The system implements self-service by automatically tracking engagement metrics such as gaze duration and interaction patterns without requiring manual input from the occupant. The system autonomously processes this data to infer user preferences and automatically adjusts POI information display priorities, filter criteria, and presentation formats according to detected user preferences.
Solution Approach 2:
The patent establishes a feedback loop where engagement metrics are continuously monitored and fed back to the information selection algorithm. This feedback mechanism allows the system to learn from occupant behavior patterns and dynamically adjust the types of POI information displayed, the timing of displays, and the level of detail provided, thereby personalizing the experience without manual configuration.

AI summary
A system for providing information to an occupant of a vehicle includes a global navigation satellite system (GNSS), a vehicle communication system, a display system configured to provide information to the occupant of the vehicle, and a vehicle controller in electrical communication with the GNSS, the vehicle communication system, and the display system. The vehicle controller is programmed to determine a location of the vehicle using the GNSS. The vehicle controller is further programmed to transmit the location of the vehicle to a remote server system using the vehicle communication system. The vehicle controller is further programmed to display a graphic using the display system. The graphic is received from the remote server system. The vehicle controller is further programmed to transmit an engagement metric of the graphic to the remote server system using the vehicle communication system.
