AI Technical Summary

Technical Problem

Existing head-up display systems in vehicles struggle with conflicting depth information between virtual and real-world views, leading to visual disturbances for drivers due to the brain's difficulty in merging augmented reality with the real landscape, and lack of full depth perception in virtual information.

Method used

A vehicle head-up display system with a controller that tracks the driver's gaze and vision type (binocular or monocular) using infrared light and cameras, adjusts the position and focus of virtual images based on gaze category, and incorporates feedback mechanisms to enhance visibility, including facial recognition for personalized settings.

Benefits of technology

The system optimizes virtual image positioning and focus to match the driver's line of sight, improving visibility and reducing visual disturbances by enhancing depth perception and adapting to individual visual capabilities.

Abstract

Head-up display system (10) for an operator (22) in a vehicle (12) with a screen (20, 120, 220), wherein the system (10) comprises: at least one tracking device (24) configured to receive visual data from the operator (22); a controller (C) designed to receive view data, wherein the controller (C) comprises a processor (P) and an accessible, non-transitory memory (M) in which instructions are recorded; wherein the controller (C) is designed to project virtual images onto the screen (20, 120, 220), the virtual images being superimposed on a real view visible to the operator (22); where the controller (C) is designed to: Determining an operator's (22) gaze category based on the view data, including a binary determination of whether the operator (22) is looking at the screen (20, 120, 220); Identifying an operator vision classification (22) based on the vision data, wherein the vision classification includes binocular vision and monocular vision; wherein determining the vision classification comprises projecting a dynamic point (130) onto the screen (20, 120, 220), and wherein the tracking device (24) is designed to detect corresponding changes in the operator's (22) pupil diameter when the dynamic point (130) is moved on the screen (20, 120, 220); and Modifying the virtual images projected onto the screen (20, 120, 220) based, among other things, on the viewing category and the view classification.
