Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia content management systems lack effective tools for dynamically controlling spatial audio characteristics, such as audio focus and zoom, which are essential for enhancing user experience in multimedia consumption.
Innovation Solution
A user interface control element that modifies spatial audio information by adjusting audio focus and zoom parameters based on user input, allowing for real-time manipulation of audio characteristics through a graphical interface with visual and haptic feedback, enabling precise control of audio directions and gains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If spatial audio information is provided with characteristic parameters, then audio focus and zoom control are enabled, but device complexity increases
Solution Approach 1:
The control element is designed to perform multiple functions: it controls both audio focus direction and audio zoom gain through a single interface element. The control element can be positioned in different regions of the display to simultaneously adjust multiple spatial audio parameters, eliminating the need for separate controls for each parameter and thereby reducing overall system complexity while maintaining versatility
2Stability of the object's composition
If control element position changes are modified according to predefined criteria, then sudden audio changes are reduced, but control responsiveness is decreased
Solution Approach 1:
The system dynamically adjusts the modification applied to control element position changes based on the magnitude of the change. Small positional adjustments are applied with minimal modification to maintain responsiveness, while large positional changes undergo greater modification to prevent sudden audio transitions. This dynamic approach allows the system to adapt its smoothing behavior to the user's interaction intensity, balancing stability and responsiveness
3Stability of the object's composition
If first path and second path of control element are provided, then audio transition smoothness is improved, but device complexity increases
Solution Approach 1:
The system pre-calculates and stores multiple possible paths (first path and second path) for the control element before the user actually moves it. These paths are prepared in advance with appropriate modification criteria already applied, so when the user interacts with the control element, the smooth transitions are achieved by selecting from pre-computed paths rather than calculating modifications in real-time, thereby reducing the computational complexity during actual operation
