Solution Overview

Problem

Existing systems lack the capability to automatically create interactive step-by-step guides from first-person camera recordings, which limits the efficiency and effectiveness of converting video and audio inputs into actionable instructional content.

Innovation Solution

An interactive guide system utilizing a wearable device with a processor equipped with natural language processing and video frame extraction modules, capable of processing video and audio inputs to generate an interactive guide file comprising video frames and text instructions, by retrieving key words stored in a memory and assembling the guide automatically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual creation of step-by-step guides is used, then instructional content can be created, but the process is time-consuming and inefficient

Engineering Contradiction:
Improveguide creation efficiencyVSAvoidtime for creating instructional content
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system automatically processes video and audio inputs to generate step-by-step guides without requiring manual intervention. The processor autonomously extracts video frames, performs speech recognition, retrieves relevant keywords, and assembles the final guide file, enabling the system to serve itself in creating instructional content.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary processing of video and audio data by extracting key frames and recognizing speech content before assembling the final guide. This preliminary action prepares the data in advance, making the subsequent guide creation process faster and more efficient.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If automatic processing of video and audio data is implemented, then guide creation efficiency improves, but system complexity increases

Engineering Contradiction:
Improveguide creation efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides the complex task of guide creation into distinct modules: video frame extraction module that processes video data, speech recognition module that processes audio data, keyword retrieval module that accesses stored keywords, and an assembly module that combines these elements into the final guide file. This segmentation makes the overall system more manageable and maintainable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The processor is designed to perform multiple functions within a single integrated system: it handles video processing, audio processing, keyword retrieval, and guide assembly. This multi-functionality reduces the need for separate dedicated systems for each task, thereby managing complexity while maintaining high productivity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Manufacturing precision

If comprehensive video and audio processing is performed, then guide quality improves, but processing time increases

Engineering Contradiction:
Improveguide qualityVSAvoidprocessing time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The system extracts only the essential and relevant components from the video and audio inputs: key video frames that represent important moments and speech recognition results that capture essential instructions. By extracting only what is necessary rather than processing all data comprehensively, the system maintains guide quality while reducing processing time.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system performs partial processing by focusing on extracting key frames and essential speech content rather than analyzing every detail of the video and audio data. This partial action approach achieves sufficient guide quality without the time cost of exhaustive processing.

Inventive Principle:
Principle #16Partial or excessive action
