Wearable Gaze Control via Virtual Display Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices that rely on gaze detection for user input can experience erroneous operations due to unintended gaze movements, which need to be minimized for accurate functionality.
Innovation Solution
A wearable device with a display area virtually divided into first and second areas, where a predetermined function is executed when the user's gaze position moves from the first area to the second area while an object corresponding to the function is displayed within the first area, utilizing a control method and program to manage gaze detection and operation control.

Engineering Contradiction Analysis
1Ease of operation
If gaze detection is used for user input operation, then hands-free operation is enabled, but erroneous operations occur due to unintended gaze movements
Solution Approach 1:
The display area is divided into multiple regions (first area, second area, third area) with different functions. The first area displays icon images for selection, the second area displays detailed information, and the third area serves as a transition zone. This spatial segmentation allows the system to distinguish between intentional selection gestures (gaze moving from first to second area) and unintentional movements (gaze moving within or between other areas), thereby reducing erroneous operations while maintaining hands-free operation
Solution Approach 2:
A gaze position detecting unit is introduced as an intermediary component that continuously monitors the user's gaze position and provides this information to the control unit. This intermediary enables the system to detect and analyze gaze movements in real-time, distinguish between intentional and unintentional movements, and make informed decisions about whether to execute operations, thus improving operation accuracy while preserving hands-free functionality
2Ease of operation
If icon images are displayed for user selection, then user interaction is enabled, but unintended gaze movements trigger wrong functions
Solution Approach 1:
The display area is segmented into a first area for displaying selectable icon images, a second area for displaying detailed information, and a third area as a transition zone. By requiring the gaze to move specifically from the first area to the second area (passing through or near the third area) to trigger a function, the system creates a more deliberate interaction pattern that reduces accidental activations while maintaining intuitive user interaction
Solution Approach 2:
The system performs preliminary detection of gaze position and movement trajectory before executing any function. The control unit monitors whether the gaze movement follows the intended path (from first area through third area to second area) and only executes the function when this preliminary condition is satisfied, preventing unintended function execution while maintaining smooth user interaction

AI summary
As one of aspects of the present invention, a wearable device includes a display having a display area virtually divided into a first area and a second area. When a user's gaze position moves from the first area to the second area while an object corresponding to a predetermined function is displayed within the first area, the predetermined function is executed. The wearable device further includes a controller for detecting a user's gaze position with respect to the display and a user's gaze movement in the display.
