Solution Overview

Problem

Current user terminal devices lack an efficient method for convenient user interaction, as they require explicit selection and manipulation of icons to access applications, leading to cumbersome navigation and delayed service access.

Innovation Solution

A user terminal device equipped with a display, detector, and controller that processes user drawing inputs as inputs for corresponding programs, allowing for direct execution of applications and services by recognizing text, symbols, and connections between objects, enabling quick and intuitive control operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional icon selection method is used, then application execution is reliable, but user interaction efficiency deteriorates due to cumbersome navigation

Engineering Contradiction:
Improveservice access speedVSAvoidnavigation complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical icon selection and menu navigation with voice command recognition. Users speak natural language commands which are processed by speech-to-text conversion and natural language understanding modules, directly triggering application execution or function invocation without manual navigation through icons or menus.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces voice recognition and natural language processing as intermediary layers between the user and the operating system. The voice input is converted to text, interpreted through NLU to determine user intent, and then mapped to corresponding system commands or application launches, serving as a mediator that translates human speech into machine actions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If manual icon selection is required, then application control is precise, but user interaction time increases

Engineering Contradiction:
Improvenavigation timeVSAvoidinput accuracy
Core Design Contradiction:
Loss of timeVSMeasurement precision

Solution Approach 1:

The patent substitutes manual icon selection with voice-based direct command input. Instead of navigating through UI elements, users speak commands that are directly interpreted by the system's speech recognition and natural language understanding components, executing the desired action immediately without intermediate navigation steps.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system performs preliminary processing of voice commands through speech-to-text conversion and natural language understanding before executing the intended action. This preliminary interpretation phase allows the system to anticipate user intent and prepare the appropriate response or application launch in advance, reducing overall interaction time.

Inventive Principle:
Principle #10Preliminary action
