Headset Visual Feedback via Indication Color
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable smart headgears face usability issues due to interference between the viewfinder image and the user's view during visual feedback, leading to poor interaction efficiency.
Innovation Solution
A headset device with an image acquisition component and a display component, where the processor determines an indication color based on the viewfinder image to indicate the viewfinder orientation, allowing the user to adjust the shooting angle without directly viewing the viewfinder image, using a full-color LED or OLED display for efficient visual feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the viewfinder image is displayed for visual feedback, then the user can determine the target object and adjust shooting angle, but the viewfinder image interferes with the user's view
Solution Approach 1:
The patent extracts the essential information from the viewfinder image (color values from preset areas) and displays only this extracted information as indication colors, rather than displaying the complete viewfinder image. This separates the useful feedback information from the harmful visual interference.
Solution Approach 2:
The patent applies local quality by displaying indication colors at specific locations (such as around the lens or on the frame) rather than displaying the viewfinder image broadly. The visual feedback is localized to provide orientation information without interfering with the user's overall view.
2Productivity
If a full-color display component is used to show indication color, then visual feedback efficiency is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent changes the display parameters by using full-color LED or OLED technology that can display various colors with a single component type. This allows the system to transmit rich visual information (different colors indicating different orientations) while maintaining a relatively simple display component structure.
3Use of energy by moving object
If the display component size is reduced to improve wearability, then power consumption decreases, but visual feedback clarity may be compromised
Solution Approach 1:
The patent uses color changes as the primary visual feedback mechanism. By displaying different colors (or color intensities) to indicate different viewfinder orientations, the system conveys rich information in a compact form that can be effectively displayed on small, low-power components.

AI summary
A head worn equipment and visual feedback method and device thereof. The head worn equipment includes: a support frame, an image acquiring component, a display component, and a processor. The image acquiring component and the display component are disposed on the support frame. When the head worn equipment is in use, the display component is within a visual perception range of a user. The image acquiring component is configured to acquire a captured image. The processor acquires the captured image acquired by the image acquiring component, determines an indication color for display on the basis of the captured image, and controls the display component to display the indication color, so as to indicate a viewing direction of the image acquiring component for the user.
