Head-Mounted Display Merging Vehicle Data for Unobstructed Forward Vision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles face challenges in providing an unobstructed view of the surroundings due to structural elements and weather conditions, leading to blind spots and distractions from multiple in-vehicle displays, which increases the risk of accidents.
Innovation Solution
A head-mounted display system equipped with sensors, a processing unit, and a display control unit that generates and projects surround information, allowing users to view their environment without diverting their line of sight, including features like stereoscopic displays, wireless connectivity, and audio processing for hands-free control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver looks at multiple in-vehicle displays (tachometer, navigation, radio, mobile phone), then the driver can access vehicle information and entertainment, but the driver's view is diverted from the main driving direction increasing accident risk
Solution Approach 1:
The patent merges multiple separate displays (instrument cluster, navigation system, radio, mobile phone) into a single head-mounted display unit that presents all information in a unified visual field in front of the driver, eliminating the need to shift gaze between multiple locations
Solution Approach 2:
The head-mounted display acts as an intermediary device that captures information from various vehicle systems and presents it in a consolidated format at a fixed location in the driver's field of view, serving as a mediator between the driver and multiple information sources
2Loss of information
If the driver uses rear view mirrors to observe blind angles, then the driver can monitor areas not visible through windows, but the driver must turn the head to the rear direction increasing distraction
Solution Approach 1:
The system uses cameras positioned at various locations around the vehicle to capture images from multiple dimensions and angles, then processes and displays these images in a composite view that presents blind angle information within the driver's forward field of view without requiring physical head movement
3Loss of information
If the driver looks through windows to observe the surrounding environment, then the driver can see outside the vehicle, but the view is obstructed by structural parts (pillars, window frames, head rests) and degraded by weather conditions
Solution Approach 1:
The system divides the vehicle's external environment monitoring into multiple segments by positioning cameras at different locations (front, rear, sides) to capture views from multiple perspectives, overcoming obstructions caused by pillars and window frames that block any single viewpoint
Solution Approach 2:
The system creates visual copies of the external environment using cameras and displays these copied images on the head-mounted display, providing the driver with a replicated view of surroundings that is not subject to physical obstructions or weather-related degradation affecting direct viewing through windows

AI summary
A head-mounted display system is provided. According to one example of an implementation, the head-mounted display system includes at least one sensor detecting surrounding information, a processing unit processing the surrounding information received from the at least one sensor, a display control unit generating display information to be displayed to a user of the system from the processed surrounding information received from the processing unit, and a head-mounted display capable of displaying information received from the display control unit to the user.
