Head-Mounted Device Mental State Guidance via Image Compositing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices that aim to lead users to a target mental state often hinder concurrent tasks due to their design, which obstructs the user's view of the peripheral environment, making it difficult to perform other activities.
Innovation Solution
A head-mounted device equipped with an image capturing system and a display that composites the user's environment with images designed to influence their mental state, allowing the user to view their surroundings while being guided towards a target mental state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable device completely covers the eyes of the user to display images for mental state guidance, then the effectiveness of leading the user to a target mental state is improved, but the user cannot visually recognize the peripheral situation and cannot do another work
Solution Approach 1:
The patent merges the real-world visual environment (captured by the image capturing device) with the mental state guidance image (displayed by the display device) into a composite image. This allows the user to simultaneously perceive both their surroundings and the guidance stimuli, enabling concurrent task performance while maintaining mental state guidance effectiveness.
Solution Approach 2:
The patent introduces an image capturing device as an intermediary to capture the user's visual environment, and a control device to process and composite the captured image with the guidance image. This intermediary system bridges the gap between the need for environmental awareness and the need for focused mental state guidance.
2Reliability
If the wearable device displays only the guidance image to lead the user to a target mental state, then the focus on mental state guidance is improved, but the user loses awareness of the surrounding environment
Solution Approach 1:
The control device composites the captured environmental image and the guidance image into a single composite image that preserves both information. The environmental image provides situational awareness while the guidance image provides mental state feedback, and their combination allows the user to maintain both awareness and focus simultaneously.
Solution Approach 2:
The patent applies local quality by allowing different regions of the display to serve different functions. The composite image can be configured to show environmental information in certain areas and guidance information in other areas, enabling the user to access both types of information without conflict.

AI summary
A control device of a head-mounted device is provided. The head-mounted device includes an image capturing device configured to capture an environment around a wearer and a display device configured to display an image to the wearer. The control device includes a first acquisition unit configured to acquire a first image captured by the image capturing device, a second acquisition unit configured to acquire a second image used to lead a mental state of the wearer to a target mental state, and a composition unit configured to composite the first image and the second image, thereby generating a third image to be displayed on the display device.
