Wearable Eye Display Interface for Touch Device Privacy and Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Touch display devices face challenges in power consumption and privacy concerns, particularly in public spaces, due to high display-related power usage and vulnerability of security codes when unlocking devices.
Innovation Solution
A novel eye display interface system separates the touch interface from the display interface, allowing the display to be deactivated on the touch device while re-creating it on a wearable eye display device, enabling private viewing and reducing power consumption by using a smaller, less power-intensive display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the display interface is kept active on the touch display device, then the user can see the interface clearly, but power consumption increases
Solution Approach 1:
The patent creates a visual copy of the touch display interface on the lens surface through optical reflection. The camera captures the display content and projects it onto the lens, which then reflects the image to the user's eye. This copying mechanism allows the interface to be visible without keeping the main display active, thereby reducing power consumption while maintaining visibility.
Solution Approach 2:
The lens serves as an intermediary element between the camera and the user's eye. The camera captures the display content and the lens reflects this image to the user, acting as a mediator that transfers visual information without requiring the main display to remain active. This intermediary mechanism enables indirect viewing that conserves energy.
2Use of energy by moving object
If the display is deactivated to save power, then power consumption decreases, but the touch interface becomes invisible to the user
Solution Approach 1:
When the display is deactivated, the camera captures the interface content before deactivation and creates a visual copy on the lens through optical reflection. This copy remains visible to the user even though the original display is turned off, preventing information loss while achieving power savings.
Solution Approach 2:
The system performs preliminary capture of the display content by the camera before deactivating the display. This preliminary action ensures that the interface information is already captured and ready to be reflected on the lens, preventing any loss of visibility when the display turns off.
3Measurement precision
If a graphical pattern is displayed to help the camera identify the device, then the camera can accurately locate the display area, but the display area must be visible to the camera
Solution Approach 1:
The graphical pattern is displayed temporarily as a preliminary action to enable the camera to identify and locate the display area accurately. Once the camera has captured the pattern and determined the display boundaries, the pattern can be deactivated, allowing subsequent interface capture without requiring continuous display activation. This preliminary identification phase consumes minimal energy compared to keeping the display continuously on.

AI summary
A wearable eye display device allows a user to use the touch interface of their touch display device while enjoying a personal view of the touch display device's display interface. During use the display screen of the touch display device is deactivated while the touch interface remains active. The wearable eye display device enables the touch display device to be used with greater privacy since the display screen is not observable to others while deactivated. In addition, power consumption is reduced since the touch display device consumes less power when viewing the display interface on the wearable eye display device instead of on the touch display device's larger display area.
