Solution Overview

Problem

Conventional methods for inputting 2-dimensional coordinates on a display screen to a virtual 3-dimensional space require additional pressure-sensitive elements, leading to increased complexity and cost, as well as a high burden on touch panels, causing frequent breakdowns and shorter lifespans due to the need for strong pressing forces for depth input.

Innovation Solution

A storage medium with an input processing program that uses a pointing device to detect 2-dimensional coordinates and convert them to 3-dimensional coordinates without requiring a separate pressing force detection function, allowing for simple conversion and reducing the load on input devices like touch panels by calculating shift amounts based on continuous and non-continuous input statuses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If pressure-sensitive elements are added to detect pressing force for 3D coordinate input, then measurement precision of depth coordinate is improved, but device complexity increases

Engineering Contradiction:

Improvedepth coordinate detection accuracyVSAvoiddevice structure complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent extracts the depth coordinate detection function from the touch panel hardware and relocates it to the software processing system. Instead of using pressure-sensitive elements in the touch panel, the system detects pressing force through software analysis of touch duration and intensity patterns, thereby eliminating the need for additional pressure detection hardware while maintaining depth coordinate measurement capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical pressure-sensitive detection system with a software-based detection mechanism. The pressing force magnitude is determined through software algorithms that analyze touch interaction characteristics rather than through physical pressure sensors, substituting a mechanical detection system with an information-processing-based system

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If pressure-sensitive elements are added to detect pressing force, then 3D coordinate input capability is improved, but manufacturing cost increases

Engineering Contradiction:

Improve3D coordinate input capabilityVSAvoidmanufacturing cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent makes the existing touch panel serve multiple functions: it detects both 2D position coordinates and 3D depth information through software processing. The same touch panel hardware that originally only detected X-Y coordinates is enhanced to also detect Z-axis depth information by analyzing touch duration and intensity patterns, eliminating the need for separate depth detection hardware

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The touch panel system performs its own depth detection function through software processing of its existing touch data. The system uses the touch information already being collected by the touch panel to determine pressing force magnitude, making the system self-sufficient without requiring additional dedicated depth detection components

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If users strongly press down on the touch panel for depth input, then 3D coordinate input range is improved, but reliability of touch panel deteriorates

Engineering Contradiction:

Improvedepth direction input rangeVSAvoidtouch panel durability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent changes the detection parameters from requiring strong physical pressing force to detecting subtle variations in touch duration and intensity. By altering what parameter is measured (from force magnitude to temporal and intensity patterns), the system achieves the same depth detection function while requiring minimal physical force from the user, thereby protecting the touch panel from damage

AI summary

An input processing device comprises a display screen and a pointing device for inputting corresponding 2-dimensional coordinates on the display screen. A 3-dimensional space is displayed on the display screen and the 2-dimensional coordinates inputted from the pointing device are detected. Next, shift amounts, per unit of time, of the detected 2-dimensional coordinates are calculated based on a predetermined calculation start condition. And the calculated shift amounts are converted to 3-dimensional coordinate shift amounts in the 3-dimensional space.
