Solution Overview

Problem

Existing touch operation methods struggle to provide fine operations and efficient cursor followability when performing operations with fingers.

Innovation Solution

A computer system with a touch panel display that displays a cursor ahead in the moving direction of the finger, allowing the cursor to jump to new relative positions based on the finger's movement, ensuring constant distance and relative angle adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cursor is displayed at a fixed position relative to the touch position, then the operation structure is simple, but the cursor followability and fine operation capability are poor

Engineering Contradiction:
Improvecursor followabilityVSAvoidoperation structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the cursor's relative position to the finger dynamic rather than fixed. The cursor is positioned ahead of the finger in the moving direction, and this relative position is adjusted based on the finger's movement direction. This dynamic adjustment improves cursor followability and fine operation capability without requiring complex additional hardware, as it utilizes the existing touch panel and display components.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If the cursor is positioned at the touch position, then the operation response is immediate, but fine operations become difficult due to lack of preview

Engineering Contradiction:
Improveoperation precisionVSAvoidoperation response time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies the preliminary action principle by positioning the cursor ahead of the finger in the moving direction. This allows the user to see where the cursor will be before actually touching that position, enabling more precise operations. The cursor serves as a preview of the upcoming touch position, allowing users to adjust their finger movement to achieve the desired target more accurately, thus improving operation precision without significant time loss.

Inventive Principle:

AI summary

There is configured a computer including a touch panel display configured to display a plurality of objects and a cursor configured to follow a finger, and an execution unit configured to execute processing corresponding to the object pointed by the cursor, wherein a relative position of the cursor with reference to the finger is changed so that the cursor is located ahead in a moving direction of the finger.
