Eye-Attached Gaze Guidance Display for Off-Target Visual Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle gaze guidance systems rely on illuminations to guide the driver's line of sight, which is ineffective when a target is present in a direction without illumination, limiting the system's ability to guide the occupant's gaze to the target.
Innovation Solution
A display control device and system that uses a processor to identify an attraction target and guide the user's line of sight through a display unit attached to the eyeball, such as smart contact lenses, without requiring physical mechanisms like illumination, by analyzing the user's intentions or movements and displaying guidance displays in the correct direction relative to the target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If illuminations are used to guide the driver's line of sight, then the guidance function is provided, but the system cannot guide the line of sight when a target is present in a direction without illumination
Solution Approach 1:
The patent replaces the mechanical illumination system with a display unit that provides visual guidance directly in the user's field of view. The display unit, attached to the eyeball, presents guidance displays that indicate target directions without requiring external light sources, thereby eliminating the limitation of illumination-dependent guidance.
Solution Approach 2:
The patent transitions from three-dimensional spatial illumination to two-dimensional display information presented on the retina. By converting the guidance mechanism from physical light direction to visual information display, the system can guide attention to any direction regardless of physical illumination availability.
2Ease of operation
If a physical mechanism such as illumination is used for guidance, then guidance can be provided in illuminated directions, but the system requires complex physical mechanisms and cannot guide to targets in dark areas
Solution Approach 1:
The patent eliminates complex physical guidance mechanisms by substituting them with a display unit that presents visual information directly to the user's eye. This replaces mechanical illumination systems with an information-based display system that requires no physical light sources or mechanical components for guidance.
Solution Approach 2:
The patent creates a virtual representation of the target direction through display information rather than using physical light sources. The guidance display presents a simplified visual indicator that copies the essential directional information without requiring the complex physical infrastructure of illumination systems.
3Loss of information
If the guidance display is displayed in a direction different from the attraction target direction, then the display can be shown, but the user cannot find the target efficiently
Solution Approach 1:
The patent implements feedback by continuously monitoring the user's line of sight direction and adjusting the guidance display position accordingly. The display unit presents guidance information that is dynamically positioned relative to the user's current gaze direction, ensuring the target indicator always appears in the correct directional context for efficient target acquisition.
Solution Approach 2:
The patent makes the guidance display dynamic by adjusting its position based on the user's eye movement and line of sight direction. Rather than a fixed display position, the guidance indicator moves dynamically to maintain the correct spatial relationship with the target direction relative to the user's changing gaze, enabling efficient target location.
Data Source
AI summary
A display control device includes a processor. The processor identifies an attraction target that guides a line of sight of an occupant, acquires the line of sight of the occupant, and causes a display unit attached to an eyeball of the occupant to display a guidance display that guides the line of sight of the occupant to the attraction target based on positional relationship between the line of sight of the occupant and the attraction target.
