Touch Graphic Equalizer Interface for Intuitive Sound Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Graphic equalizers are not user-friendly for inexperienced users, such as children and the elderly, as they require understanding of complex frequency adjustments, making it difficult to provide an intuitive and easy-to-use interface for sound effect adjustments.
Innovation Solution
A sound effect adjusting apparatus with a touch panel display that uses a single shape graphic to represent multiple sound output parameters, allowing users to adjust these parameters through intuitive gestures, such as pinching or sliding, which changes the shape of the graphic and correspondingly adjusts the sound effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a graphic equalizer with multiple frequency knobs is used, then sound effect adjustment capability is improved, but ease of operation deteriorates for inexperienced users
Solution Approach 1:
The patent merges multiple frequency adjustment knobs into a single graphical interface element that responds to touch gestures. Instead of requiring users to manipulate multiple separate knobs for different frequencies, the system combines all frequency adjustments into one unified graphic that can be modified through simple touch operations, thereby maintaining sound effect adjustment capability while dramatically improving ease of operation for inexperienced users
Solution Approach 2:
The patent replaces the mechanical knob system with a touch-sensitive graphical interface. The physical act of rotating multiple knobs is substituted with touch-based gestures on a display screen, eliminating the need for users to understand mechanical adjustments and making the interface more intuitive and accessible to users of all skill levels
2Adaptability or versatility
If multiple frequency adjustment controls are provided, then sound effect customization is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple frequency control functions into a single graphical representation. Instead of providing separate physical controls for each frequency band, the system uses one unified graphic element that encompasses all frequency adjustments, thereby maintaining full sound effect customization capability while reducing the apparent complexity of the device interface
Solution Approach 2:
The single graphical interface element serves multiple functions simultaneously - it represents multiple frequency bands, allows for various types of adjustments (boost, cut, shelving), and responds to different touch gestures. This multi-functionality eliminates the need for separate dedicated controls for each function, reducing device complexity while preserving comprehensive sound effect customization

AI summary
An information processing apparatus includes a processor that controls display of a graphic including a single shape, where the single shape corresponds to a plurality of content output characteristic adjusting parameters. The processor also modifies the single shape included in the graphic displayed on the display based on input information, and adjusts at least one content output characteristic adjusting parameter of reproduced content based on the input information.
