Gaze-Controlled Interface with Static Confirm Buttons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gaze-controlled interfaces for computing devices face challenges with inaccuracy and inadvertent clicking due to involuntary eye movements and the unnatural, tiring nature of conscious eye control, particularly with dwell click alternatives that require constant visual attention and confirmation steps.
Innovation Solution
A method and system that utilize static confirm buttons with distinct visual identifiers placed at fixed locations around the screen, where activatable elements are assigned corresponding visual identifiers, and the confirm buttons are dynamically linked to the intended activatable elements based on gaze data, allowing for precise and efficient interaction without constant visual confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If dwell click alternative is used to perform actions with eye gaze, then action execution is enabled, but inadvertent clicking increases due to involuntary eye movements
Solution Approach 1:
The patent introduces an intermediary confirmation step between gaze detection and action execution. Instead of directly triggering actions on dwell, the system presents confirm buttons that require a second confirmation action, effectively mediating between the user's gaze and the final action to prevent inadvertent clicks
Solution Approach 2:
The system performs a preliminary confirmation action before executing the final action. The confirm buttons are presented and must be selected before the actual action occurs, allowing the user to verify their intent before commitment
2Measurement precision
If magnification is applied to resolve multiple activatables in gaze area, then click accuracy improves, but visual distraction and content visibility decrease
Solution Approach 1:
The patent segments the interface by separating the main display content from the confirmation controls. The confirm buttons are presented in a distinct confirmation area rather than overlaying or magnifying the content area, allowing precise selection without compromising content visibility
Solution Approach 2:
The system transitions from a two-dimensional content display to a third spatial arrangement by placing confirm buttons in a separate confirmation area, effectively adding a dimensional separation between content consumption and action execution
3Reliability
If temporarily appearing confirm buttons are used, then inadvertent clicking is reduced, but user distraction and fatigue increase due to constant appearing and disappearing
Solution Approach 1:
The confirm buttons are presented in advance in a stable confirmation area before the user needs to make their selection. This preliminary presentation allows the user to see all available options without them appearing and disappearing dynamically, reducing cognitive load and fatigue
4Measurement precision
If multiple confirm buttons are presented to compensate for gaze inaccuracy, then click accuracy improves, but interface complexity and time to select correct button increase
Solution Approach 1:
The patent applies local quality by providing contextual information specifically in the confirmation area. The confirm buttons are labeled or highlighted based on the current gaze context, allowing the user to quickly identify the relevant button without scanning through all possible options
Data Source
AI summary
A gaze-controlled interface system for enabling a user to interact with an electronic visual work presented on an electronic display screen. The system has an electronic display screen configured to present the electronic visual work and an eye gaze tracker configured to sense the user's gaze position on the display screen and generate representative gaze signal. A processor receives and processes the gaze signal to enable the user to interact with the electronic visual work based on gaze.
