Heads-up Display Augmented Reality Driver Training System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Driver engagement and safety during routine commuting are compromised due to lack of stimulation, low investment in driving behavior, and absence of feedback, leading to increased distraction and potentially hazardous driving habits.
Innovation Solution
A driver training system utilizing a heads-up display to present driving cues as augmented reality graphic elements, continuously monitoring and providing feedback on adherence to these cues, encouraging safe driving behaviors by reducing the number of surrounding vehicles, following merging paths, and yielding appropriately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a driver engages in routine commuting without feedback mechanisms, then the driver may feel comfortable and relaxed, but driver engagement decreases and distraction increases
Solution Approach 1:
The system continuously monitors driving behavior through sensors and provides real-time feedback via augmented reality graphic elements displayed on the windshield. The feedback controller generates adherence feedback based on comparison between actual driving behavior and desired driving behavior, maintaining driver engagement without compromising comfort.
2Device complexity
If no feedback on driving performance is provided, then the system remains simple, but driver behavior goes uncorrected and safety decreases
Solution Approach 1:
The feedback controller compares actual driving behavior data from sensors against desired driving behavior criteria and generates adherence feedback. This feedback is processed to determine levels of adherence and communicated to the driver through the heads-up display, enabling behavior correction while maintaining relatively simple system architecture.
Solution Approach 2:
The augmented reality graphic elements serve as an intermediary communication channel between the monitoring system and the driver. Rather than using complex alerts or multiple display devices, the system projects intuitive visual cues directly onto the windshield, providing safety feedback without adding significant system complexity.
3Device complexity
If driving cues are not presented to the driver, then the display system remains simple, but driver behavior cannot be guided or improved
Solution Approach 1:
The system transitions from traditional two-dimensional display screens to three-dimensional augmented reality graphic elements projected onto the windshield. This dimensional change allows driving cues to be presented in the driver's natural field of view, integrating information guidance without adding complex display hardware.
4Device complexity
If the driver's attention is not monitored, then the monitoring system remains simple, but adherence to safe driving behaviors cannot be measured or reinforced
Solution Approach 1:
The system uses the vehicle's existing sensor infrastructure to monitor driving behavior, allowing the vehicle itself to provide the monitoring data. The feedback controller processes this self-generated data to measure adherence to desired driving behaviors, eliminating the need for separate complex monitoring hardware.

AI summary
A driver training system includes a training controller, a heads-up display device, and a driving cue adherence controller. The training controller is configured to receive inputs related to an operational state of a vehicle and an environment surrounding the vehicle, and to determine a driving cue based on the received inputs. The heads-up display device is configured to present the driving cue as an augmented reality graphic element in view of a driver by projecting graphic elements on a windshield of the vehicle. The driving cue adherence controller is configured to continuously determine a current level of adherence to the driving cue, and an aggregate level of adherence to the driving cue based on the continuously determined current level of adherence to the driving cue over a predetermined time period. The heads-up display device is configured to present the continuously determined aggregate level of adherence in view of the driver.
