Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 3D audio design tools, such as keyboards and mice, are limited in their ability to navigate and control 3D audio environments due to their two-dimensional interfaces, making sound design cumbersome and difficult.
Innovation Solution
A motion-sensing controller with a handheld body that allows users to intuitively control 3D audio parameters by visually ascertaining its orientation relative to a predetermined reference, using orientation-sensing components like cameras or magnetic fields to generate output signals for controlling sound sources or listener positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional computer peripherals (keyboard and mouse) are used to control 3D audio design, then the device complexity is low, but the ease of operation deteriorates due to limited ability to represent and navigate 3D spaces
Solution Approach 1:
The patent transitions from two-dimensional keyboard/mouse interfaces to a three-dimensional handheld controller with spatial orientation capabilities. The controller body's orientation in 3D space directly corresponds to sound source positions and listener orientations in the virtual 3D audio environment, enabling intuitive spatial control that matches the dimensional nature of the audio design task.
Solution Approach 2:
The patent replaces conventional mechanical input devices (keyboard and mouse) with a motion-sensing controller that uses orientation sensing components (such as accelerometers, gyroscopes, or magnetometers) to detect spatial orientation. This substitution enables direct mapping between physical controller orientation and virtual audio parameters, significantly improving ease of operation in 3D audio design.
2Reliability
If motion sensing based on relative changes in orientation is used, then the device complexity is low, but the reliability deteriorates due to positional drift from integrating acceleration measurements over time
Solution Approach 1:
The patent employs orientation sensing components that provide continuous feedback on the controller body's orientation relative to a predetermined reference orientation. This feedback mechanism allows the system to maintain accurate orientation information without integrating acceleration measurements over time, thereby preventing positional drift while ensuring reliable orientation data for controlling audio parameters.
