Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image sound output devices lack an efficient mechanism to adjust the timing of changing the sound output mode in response to a user's gaze direction, which limits their effectiveness in synchronized image and sound presentations.
Innovation Solution
An image sound output device comprising a display screen, a sound output device, a gaze point detector, an area setting unit, a determination unit, and an output controller that adjusts the sound output mode based on the user's gaze position within a specific area on the screen or image, allowing for synchronized and dynamic control of image and sound presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gaze detection technology is applied to adjust sound output timing, then the synchronization and engagement of image and sound presentations is enhanced, but the device complexity increases due to additional components like gaze point detector, area setting unit, determination unit, and output controller
Solution Approach 1:
The gaze detection device integrates multiple functions including image display, sound output, gaze point detection, area setting, determination, and output control into a single system. This multi-functionality allows the device to enhance synchronization efficiency while managing complexity by consolidating control capabilities rather than adding separate independent systems.
Solution Approach 2:
The determination unit acts as an intermediary that receives gaze position data and sound output requests, processes this information against stored determination criteria, and generates control signals for the output controller. This intermediary layer manages the complexity by centralizing the decision-making logic for synchronizing sound output with user gaze, rather than requiring direct complex interactions between all system components.
2Speed
If the system continuously monitors gaze position to adjust sound output, then the responsiveness to user attention is improved, but the processing time and computational load increase
Solution Approach 1:
The system performs preliminary actions by storing determination criteria in advance in the determination unit's storage. These pre-stored criteria include conditions for adjusting sound output based on gaze position. By having these decision rules prepared beforehand, the system can quickly compare real-time gaze data against predefined conditions without performing complex computations during real-time operation, thus improving responsiveness while minimizing processing time.
Solution Approach 2:
The system implements partial monitoring by focusing gaze detection on specific areas of interest rather than continuously analyzing the entire display area. The area setting unit defines specific regions where gaze detection is performed, allowing the system to maintain responsiveness to user attention in critical areas while reducing the overall computational load and processing time required for comprehensive monitoring.
