Three-Dimensional Eye Display for Spatial Robot Attention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot technology struggles to accurately convey the target of attention in a three-dimensional real space, leading to ambiguity and hindrances in communication due to the incompatibility between the displayed virtual space and the user's outer appearance, making it difficult for third parties to intuitively grasp the robot's focus.
Innovation Solution
A display system that generates and displays a three-dimensional eye image on a three-dimensional display, adjusting the target of attention image based on distance and location relative to the user, allowing for clear communication of the robot's focus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a two-dimensional eye image is displayed on a display unit to show the robot's attention direction, then the robot can convey attention information, but the target of attention becomes ambiguous in three-dimensional real space
Solution Approach 1:
The patent transitions from two-dimensional eye image display to three-dimensional eye image display. The three-dimensional eye image is generated by superimposing a virtual image of the eye onto the robot's actual eye using optical components, allowing the attention target to be represented in three-dimensional space with depth information, thereby resolving the ambiguity of two-dimensional representation.
2Loss of information
If a head mounted display is used to show virtual space and user attention location, then attention information can be displayed, but third persons find it difficult to intuitively grasp the target of attention
Solution Approach 1:
The patent creates a visual copy of the user's eye and attention state projected onto the robot's eye. The three-dimensional eye image serves as a copy that translates the user's internal attention state into an externally visible form that third persons can easily perceive and understand, bridging the communication gap.
3Loss of information
If the virtual space is displayed on the front display of head mounted display, then user attention can be indicated, but there is incompatibility with the user's outer appearance hindering communication
Solution Approach 1:
The patent merges the user's actual eye appearance with the virtual attention information by projecting the three-dimensional eye image onto the robot's eye. This combination integrates the biological reality of the eye with the virtual attention representation, creating a unified visual output that is both realistic and informative, thereby eliminating communication hindrances.

AI summary
A display system includes an image generator which generates a three-dimensional eye image that is overlain and displayed in an eye or on the eye of an image of a target of attention that is related to the target of attention, and causes the generated eye image to be displayed on a three-dimensional display. The image generator causes the eye image, of which the target of attention image has changed according to the target of attention, to be displayed on the three-dimensional display.
