Wearable Display Orientation Adjustment Using Central and Blind Spot Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable displays face challenges in matching eye perception with display content, as existing systems fail to adjust accurately when the eye location shifts, leading to usability issues due to predefined eye location and seeing angles.
Innovation Solution
A method and system for a wearable display that includes displaying a central mark and a blind spot mark on a background image, with a processing unit controlling the display to adjust the orientation by aligning the marks within specific angles and distances, allowing users to adjust the display to match vision perception with content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wearable display uses predefined eye location and seeing angle, then the device structure is simple, but the display cannot detect eye location shifts and cannot adjust orientation accurately
Solution Approach 1:
The patent displays a central mark and a blind spot mark on the display screen before the user performs the alignment action. These marks are prepared in advance to guide the user in adjusting the display orientation, enabling accurate eye location detection without complex automated tracking mechanisms.
Solution Approach 2:
The patent introduces an intermediary adjustment mechanism that allows the user to manually adjust the display orientation by aligning the central mark and blind spot mark with their eyes. This intermediary manual adjustment process bridges the gap between simple device structure and accurate orientation detection.
2Adaptability or versatility
If the wearable display uses predefined seeing angle, then the display content is fixed and simple, but the display content cannot match the user's vision perception when eye location shifts
Solution Approach 1:
The patent employs a feedback mechanism where the user observes the position of the central mark and blind spot mark relative to their eyes, and adjusts the display orientation accordingly. This visual feedback loop enables the display to adapt to the user's eye location and maintain proper alignment between display content and vision perception.
Solution Approach 2:
The patent transforms the fixed predefined seeing angle into a dynamic adjustable parameter. By allowing the user to manually adjust the display orientation based on the displayed marks, the system becomes adaptable to different eye locations while maintaining ease of operation through intuitive visual guidance.
3Reliability
If the wearable display does not provide orientation adjustment, then the device is simple to operate, but the display content cannot be aligned with the user's vision perception
Solution Approach 1:
The patent displays the central mark and blind spot mark in advance to guide the user through the adjustment process. These pre-displayed marks eliminate the need for trial-and-error adjustment, reducing the time required to achieve proper alignment while ensuring reliable vision perception matching.
Solution Approach 2:
The patent enables the user to perform the orientation adjustment themselves by simply observing the position of the displayed marks relative to their eyes. This self-service adjustment mechanism ensures reliable alignment without requiring complex automated systems or professional calibration procedures, minimizing the time investment required.

AI summary
A wearable display and an adjusting method thereof are provided. The adjusting method comprises the following steps. A background image is provided. A central mark is displayed and overlapped with the background image. A first sight line passes through the central mark. A blind spot mark is displayed and overlapped with the background image. A second sight line passes through the blind spot mark. An included angle between the first sight line and the second sight line is substantially 14 to 16 degrees.
