Wearable Sound Localization Display for Auditory Task Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work education systems using head-mounted wearable displays are unable to present knowledge of auditory tasks to learning workers.
Innovation Solution
A wearable terminal equipped with an image obtainer, sound obtainer, specifier, and presenter that identifies and presents a point of interest where a predetermined sound occurs, allowing for the presentation of auditory tasks through augmented reality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a head-mounted wearable display is used for work education, then visual work actions can be presented to the learning worker, but auditory tasks cannot be presented
Solution Approach 1:
The wearable terminal is enhanced with multiple functional modules including sound obtainer, image obtainer, specifier, and presenter. This multi-functional design enables the device to handle both visual and auditory task presentation, transforming it from a single-purpose visual display device into a versatile work education tool that can present comprehensive task information including auditory elements
Solution Approach 2:
The specifier module acts as an intermediary that processes sound information and image data to identify points of interest where specific sounds occur. This mediator connects the raw sensory inputs (sound and image) with the presentation output, enabling the system to translate auditory information into visually presentable forms through the presenter module
2Loss of information
If sound information is obtained and processed to specify points of interest, then auditory task knowledge can be presented, but device complexity increases
Solution Approach 1:
The system is divided into distinct functional modules: sound obtainer for capturing audio, image obtainer for capturing visual data, specifier for processing and identifying points of interest, and presenter for displaying results. This segmentation allows each module to perform its specific function independently, making the complex task of auditory information processing manageable and maintainable
Solution Approach 2:
The wearable terminal integrates multiple previously separate functions (sound acquisition, image acquisition, sound analysis, and visual presentation) into a single unified device. This merging consolidates the system into one wearable unit, reducing the need for multiple separate devices while maintaining the capability to process and present both auditory and visual task information

AI summary
A wearable terminal is a wearable terminal that can be worn by a user, and includes: an image obtainer that obtains an image of a subject appearing in a field of view of the user; a sound obtainer that obtains sound information including a sound occurring in a vicinity of the wearable terminal and a direction of occurrence of the sound; a specifier that, based on the sound information and the image, specifies a point of interest, the point of interest being a location, in the subject, where a sound in a predetermined band included in the sound has occurred; and a presenter that presents, to the user, an object indicating the point of interest.
