Solution Overview

Problem

Existing technologies fail to effectively associate a user's position and direction with corresponding speech information, limiting the ability to provide immersive and location-specific audio experiences.

Innovation Solution

A speech providing system that includes a user terminal and a server device, equipped with positioning and direction detection capabilities, which acquires and reproduces speech data corresponding to the user's location and direction, allowing for the provision of location-specific audio based on the user's position and attributes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If speech information is provided based on user position and direction, then user experience and location-specific audio provision are improved, but device complexity and processing requirements increase

Engineering Contradiction:

Improvelocation-specific audio provisionVSAvoidsystem complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides speech information into multiple channels corresponding to different directions and positions. Each speech channel is independently managed and can be selectively provided to the user based on their location and orientation, allowing complex spatial audio provision without overwhelming system complexity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A server acts as an intermediary between the user terminal and speech information sources. The server receives position and direction data from the user terminal, determines appropriate speech information, and provides it to the user. This intermediary approach simplifies the user terminal's complexity while enabling sophisticated location-based audio provision

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If position and direction detection capabilities are added, then speech association accuracy is improved, but device complexity and cost increase

Engineering Contradiction:

Improveposition and direction detection accuracyVSAvoiddetection system complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The user terminal utilizes existing positioning and direction detection capabilities that can serve multiple functions. These detection systems are not dedicated solely to speech provision but can support other applications as well, reducing the need for specialized expensive hardware

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system leverages the user terminal's own positioning and direction detection capabilities rather than requiring external specialized equipment. The user terminal self-provides the detection data needed for speech association, eliminating the need for additional detection devices

Inventive Principle:

Principle #25Self-service

AI summary

A speech providing device includes a memory that stores instructions, and a processor that executes the instructions. The instructions cause the processor to perform acquiring a position of a user and a direction that the user is facing, and providing a speech corresponding to an area existing in a direction that the user is facing on the basis of the position of the user, to the user.
