Solution Overview

Problem

The small size of mobile devices makes it difficult for users to accurately select specific data on touch screens, often leading to the selection of adjacent data and subsequent unnecessary processing.

Innovation Solution

An information processing apparatus that detects touch inputs on a touch panel, extracts character strings based on the touch operation, prioritizes them, and controls the display to show the extracted strings in order, allowing for precise selection and processing of desired data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the touch screen displays data in a compact layout to accommodate small device size, then the device portability is improved, but the accuracy of data selection deteriorates

Engineering Contradiction:

Improvedevice sizeVSAvoiddata selection accuracy

Core Design Contradiction:

Volume of moving objectVSMeasurement precision

Solution Approach 1:

The patent segments the data selection process into multiple stages: initial touch input, candidate character string extraction, priority-based filtering, and final selection display. This segmentation allows the system to maintain compact display while improving selection accuracy by processing and filtering candidates before final user selection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary processing layer between the touch input and final data selection. The controller extracts multiple candidate character strings, prioritizes them based on matching criteria, and presents a filtered list to the user. This intermediary process resolves the contradiction by enabling accurate selection without requiring larger display space.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If multiple touch operations are required to achieve accurate data selection, then the data selection accuracy is improved, but the operation complexity increases

Engineering Contradiction:

Improvedata selection accuracyVSAvoidoperation simplicity

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent performs preliminary actions by automatically extracting and prioritizing candidate character strings before the user makes their final selection. The system pre-processes the data by identifying potential matches and ranking them, so the user only needs to select from a pre-filtered list rather than searching through all possible options.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system provides self-service by automatically filtering and prioritizing character strings based on the touch input location and predefined criteria. This reduces the cognitive load and operational steps required from the user, as the system actively assists in identifying the correct data rather than requiring multiple manual selection attempts.

Inventive Principle:

Principle #25Self-service

AI summary

An information processing apparatus that detects touch input at a touch panel disposed on or formed integrally with a display, extracts one or more character strings from a plurality of character strings displayed on the display based on the detected touch input, prioritizes the extracted one or more character strings, and controls the display to display the extracted one or more character strings in order based on the prioritizing.
