Sight-Line Tracking Dynamic UI for Content Execution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional content execution methods using sight-line information require users to stare at a content for a pre-designated time and do not allow movement before execution, leading to unintended content execution when the user is not intending to do so.
Innovation Solution
An electronic device with a sight-line tracking module and processor that dynamically varies the user interface based on sight-line movement, allowing content execution only when a pre-designated condition is met, such as a specific path or movement direction, thereby enabling fast and efficient content execution without the need for separate input devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user must stare at content for a pre-designated time before execution, then the system can identify user intent, but the user cannot move the sight-line to another location before execution is completed
Solution Approach 1:
The system transitions from a static fixed-time staring requirement to a dynamic sight-line movement-based execution mechanism. The execution condition changes from merely maintaining gaze for a predetermined time to actively moving the sight-line along a specific path, allowing the user to control execution timing through movement patterns while maintaining reliable intent identification.
Solution Approach 2:
The system changes the parameter for content execution from time-based (fixed duration stare) to movement-based (sight-line path following). By monitoring the trajectory and pattern of sight-line movement rather than just duration, the system enables users to indicate execution intent through deliberate movement patterns while preventing accidental execution from temporary pauses.
2Extent of automation
If the system executes content after a pre-designated time lapse from staring, then content execution is automated, but content may be executed even when the user does not intend to execute it
Solution Approach 1:
The system provides visual feedback by displaying the dynamic UI that varies according to sight-line movement. This feedback mechanism allows users to confirm their execution intent in real-time by observing how their sight-line movement is being interpreted, enabling correction before final execution and preventing unintended content activation.
Solution Approach 2:
The dynamic UI serves as an intermediary between the user's sight-line movement and content execution. Instead of directly executing content based on gaze duration, the system first translates sight-line movement into a dynamic UI representation, which then triggers execution only when the movement pattern satisfies predetermined conditions. This intermediary step ensures accurate intent recognition while maintaining automation.
3Productivity
If the system requires fast sight-line movement for efficient content execution, then execution speed is improved, but precision in controlling execution timing may be reduced
Solution Approach 1:
The system dynamically adjusts the interpretation of sight-line movement by monitoring the path and pattern rather than relying solely on speed. Users can execute content quickly by making deliberate movements along the correct path, while the system's path-based detection ensures precise timing control by recognizing the specific movement pattern that indicates intent, regardless of exact speed variations.
