Depth-Aware Display Control for Reducing User Discomfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices that superimpose images on external views can cause user discomfort due to changes in image convergence angles, leading to increased burden on the user, especially when the image position changes in the depth direction.
Innovation Solution
An information processing device with a first display control unit for controlling the position of a display object in the depth direction based on eye movement and a second display control unit for controlling the state of the object, using different control relations in different ranges to minimize user discomfort and burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the convergence angle for the image is adjusted to reduce the difference with the external image convergence angle, then the burden on the user is reduced, but the position of the image in the depth direction changes and the user may feel uncomfortable
Solution Approach 1:
The patent applies dynamics by making the display control adaptive and variable based on observed eye movement characteristics. The system dynamically adjusts the convergence angle correction amount according to the user's actual eye movement data, transitioning from a static fixed correction approach to a dynamic adaptive approach that responds to individual user behavior patterns.
Solution Approach 2:
The patent changes the parameter of convergence angle correction by introducing a variable correction amount based on eye movement characteristics. Instead of using a fixed convergence angle adjustment, the system modifies the correction parameter dynamically according to measured eye movement data, allowing optimization of both user burden reduction and comfort maintenance.
2Reliability
If the position of the display object in the depth direction is controlled based on eye movement, then user comfort is maintained, but the complexity of the control system increases
Solution Approach 1:
The patent implements feedback by measuring the user's eye movement characteristics and using this information to adjust the display control parameters. The system continuously monitors eye movement data and feeds this information back to modify the convergence angle correction, creating a closed-loop control system that adapts to individual user behavior while maintaining comfort.
Solution Approach 2:
The patent applies self-service by enabling the system to automatically measure and analyze the user's own eye movement characteristics and use this self-generated data to optimize the display control. The user's natural eye movements serve as the input signal that the system processes to automatically adjust parameters, eliminating the need for manual calibration or external intervention.

AI summary
There is provided an information processing device, an information processing method, and a program capable of suppressing a user's uncomfortable feeling while reducing the burden on the user, the information processing device including: a first display control unit configured to perform first control with respect to a position of a display object in a depth direction, the position being perceived by a user on a basis of an eye movement; and a second display control unit configured to perform second control with respect to a state of the display object, the state not including the position in the depth direction as a state. The first display control unit and the second display control unit perform control based on a first relation in a first range in the depth direction, and perform control based on a second relation in a second range in the depth direction, the second relation being different from the first relation, the second range being different from the first range.
