Wearable Audio Device for Latent Demand Word-of-Mouth Presentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for presenting word-of-mouth information require users to input text-based search keywords and only cater to intentional demands, failing to reflect latent user needs.
Innovation Solution
An information processing device and method that estimates latent user demands based on current conditions and presents relevant word-of-mouth information audibly, using a wearable device with sound analysis and sensor integration to provide context-aware, unconscious information needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If text-based search is used to present word-of-mouth information, then users can find information matching their intentional demand, but users must perform text input operations and latent demands are not reflected
Solution Approach 1:
The patent replaces the mechanical text input system with an acoustic recognition system. The sound collecting unit captures user speech, the sound analyzing unit converts speech to text, and the word-of-mouth information searching unit uses this converted text to retrieve information. This substitution eliminates the need for manual text input operations while preserving user intent through speech-based interaction.
Solution Approach 2:
The patent introduces speech-to-text conversion as an intermediary between the user's latent demand (expressed orally) and the information search system (which processes text). The sound analyzing unit acts as the mediator that transforms spoken words into searchable text, enabling the system to access latent demands that users may not consciously formulate as search queries.
2Reliability
If word-of-mouth information is presented based on intentional user demand, then users receive information they consciously seek, but latent demands remain unaddressed
Solution Approach 1:
The patent performs preliminary sound collection and analysis before the user completes their information search request. The sound collecting unit continuously captures user speech, and the sound analyzing unit pre-processes this speech into text that can be immediately used for information retrieval. This preliminary processing enables the system to respond to latent demands as they emerge, rather than waiting for formal search queries.
Solution Approach 2:
The patent implements a feedback mechanism where the presented word-of-mouth information is monitored for user engagement. The system observes whether users interact with the presented information, and this feedback is used to refine future information presentation. This allows the system to adapt to both intentional and latent demands by learning from user behavior patterns.

AI summary
There is provided an information processing device and an information processing method that are able to audibly present, to a user, word-of-mouth information in accordance with the user's latent demand. The information processing device that includes a controller that performs control to estimate a latent demand on the basis of a current user condition, search for word-of-mouth information corresponding to the demand, and present the searched word-of-mouth information to a user.
