Sound Localization Control via Emoji Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in controlling and communicating the format and localization of sound during electronic communications, particularly in determining whether the recipient hears sound as stereo, mono, or binaural, and in specifying the location of binaural sound relative to the listener.
Innovation Solution
A method and apparatus that allow a user to select and control how and where sound localizes for a listener, enabling the selection of sound formats such as stereo, mono, or binaural, and specifying the location of binaural sound using graphical representations and head-related transfer functions, allowing for precise sound localization outside the listener's head.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound localization control is implemented to allow users to select sound format and location, then sound communication effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary system that translates user selections (sound format and location preferences) into appropriate audio rendering parameters. This intermediary layer manages the complexity by abstracting the complex audio processing requirements behind a simple user interface, allowing users to control sound localization without directly managing the underlying technical complexity of multiple audio formats and spatial rendering algorithms.
2Adaptability or versatility
If multiple sound formats (stereo, mono, binaural) are supported with precise localization control, then adaptability is improved, but ease of operation deteriorates
Solution Approach 1:
The system implements a universal control mechanism that handles multiple sound formats (stereo, mono, binaural) and localization options through a single integrated interface. This multi-functional approach allows the same user interface to adapt to different audio scenarios and formats without requiring separate controls for each sound type, thereby maintaining ease of operation while supporting diverse audio capabilities.
Solution Approach 2:
The patent utilizes parameter changes to simplify user interaction by allowing users to select from predefined sound format options (stereo, mono, binaural) and localization positions. The system automatically adjusts the underlying audio parameters based on user selections, transforming complex audio configuration into simple parameter selection and improving ease of operation while maintaining adaptability.
3Measurement precision
If precise sound localization control is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-defining localization positions and sound format configurations. Users select from pre-established options for sound location and format, and the system automatically configures the appropriate audio processing parameters in advance. This preliminary preparation of audio configurations enables precise sound localization control while managing device complexity through automated parameter management.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to accurately control and communicate the sound format and localization, ensuring that recipients experience sound as intended, enhancing the effectiveness of sound communication and localization in electronic communications.
Implementation Method 1
A processor or sound hardware processes or convolves the sound with one or more head-related transfer functions (HRTFs) so that the sound will externally localize away from a head of the person

AI summary
A method displays an emoji that enables a user to select how or where sound will localize to a listener of the sound associated with the emoji. During an electronic communication between a first user and a second user, the first user selects how or where sound of the emoji will localize to the second user. When the second user receives the emoji, the sound plays to the second user how or where as selected by the first user.
