Solution Overview

Problem

The existing methods require significant user effort in manually moving a pointer for input operations, leading to a high workload.

Innovation Solution

An input support system that calculates feature points from an image, displays a pointer on a screen, receives user inputs, and automatically moves the pointer to specified positions based on these feature points, reducing the need for manual pointer movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the user manually moves the pointer for input operations, then the user can precisely control the pointer position, but the workload becomes large

Engineering Contradiction:

Improveworkload of pointer movementVSAvoidcomplexity of input process

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary action by automatically calculating feature point positions from the input image and pre-positioning the pointer at these calculated locations. This eliminates the need for users to manually move the pointer across the screen, significantly reducing the workload of pointer movement while maintaining input precision through the calculated feature point positions.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the system automatically moves the pointer to feature point positions, then the workload is reduced, but the system complexity increases

Engineering Contradiction:

Improveinput efficiencyVSAvoidcomplexity of input support system

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system replaces the mechanical manual pointer movement with an automated computational system. The calculation unit automatically computes feature point positions based on image processing, and the display control unit automatically positions the pointer at these calculated locations. This substitution of manual mechanical operation with automated computational processes increases input efficiency while the added complexity is confined to the computational layer rather than requiring complex hardware modifications.
