Gaze-Controlled Display Content Switching via Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices lack an efficient method to dynamically switch or scroll content without requiring separate input operations like touch or gesture inputs, especially when displaying content across multiple areas based on user gaze direction.
Innovation Solution
A display device equipped with a display unit, an image capturing unit, and a processor that detects a user's gaze location to display content in different areas, allowing seamless switching or scrolling of content by moving the gaze, without the need for explicit input operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If touch input or gesture input is used to switch content, then content switching is achieved, but operation complexity increases and user convenience decreases
Solution Approach 1:
The system uses the user's natural gaze behavior to automatically trigger content switching without requiring explicit input actions. The display device detects gaze location and autonomously switches content based on where the user is looking, making the system serve itself by utilizing existing user behavior patterns rather than requiring additional input operations.
Solution Approach 2:
The patent replaces mechanical input methods (touch screens, gesture recognition) with an optical detection system. Instead of requiring physical contact or complex hand movements, the system uses an image capturing unit to detect the user's gaze location through optical means, substituting mechanical interaction with optical field-based detection.
2Adaptability or versatility
If multiple display areas are used to show different content, then content diversity increases, but user navigation complexity increases
Solution Approach 1:
The system continuously monitors the user's gaze location and uses this feedback to dynamically adjust content display across multiple display areas. When the user looks at a specific area, the system detects this through the image capturing unit and automatically adjusts which content is displayed in which area, creating a closed-loop system that adapts to user attention in real-time.
Solution Approach 2:
The content allocation across multiple display areas is not static but dynamically adjusts based on detected gaze locations. The system can switch content between display areas in real-time as the user's gaze moves, making the multi-display system adaptable and easy to navigate without requiring manual intervention.
3Ease of operation
If gaze detection is implemented, then input operation is simplified, but device complexity increases
Solution Approach 1:
The image capturing unit serves multiple functions: it captures the user's gaze location for content switching, and can also be used for other purposes such as taking photos or videos. By making the detection component multi-functional, the patent reduces the need for dedicated specialized hardware, thereby minimizing the increase in device complexity while still achieving gaze-based control.
