Solution Overview

Problem

Current touch input devices face challenges in accurately distinguishing between single-tap and double-tap operations due to the reliance on a predetermined waiting time, leading to poor user operation tracking when the next input does not follow immediately after the first.

Innovation Solution

An information processing apparatus that detects input operations by recognizing movement parallel to the input surface, allowing for immediate response to a first operation without waiting for a subsequent input, based on predetermined conditions such as movement distance and direction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a predetermined waiting time is provided to determine whether a following input will occur, then the reliability of operation recognition is improved, but the response time is delayed and user operation tracking becomes poor

Engineering Contradiction:
Improveoperation recognition accuracyVSAvoidresponse time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by detecting movement of the operating object in the proximity state before the final determination of operation completion. By proactively analyzing movement direction and distance in advance, the system can preliminarily determine whether a following input is likely to occur, enabling timely response without excessive waiting time while maintaining reliable operation recognition.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If a waiting time is provided to distinguish single-tap and double-tap operations, then the measurement precision of operation type is improved, but the productivity of operation response is reduced

Engineering Contradiction:
Improveoperation type distinction accuracyVSAvoidoperation response speed
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent replaces the mechanical time-based waiting approach with a movement-based detection mechanism. Instead of relying solely on temporal waiting periods, the system uses proximity position detection and movement analysis to distinguish between single-tap and double-tap operations, enabling more precise operation type identification without the productivity loss associated with extended waiting times.

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

3Reliability

If the operating object is required to remain in proximity state for a predetermined time, then the reliability of operation completion determination is improved, but the ease of operation is reduced due to strict timing requirements

Engineering Contradiction:
Improveoperation completion determination accuracyVSAvoiduser input convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the proximity state detection adaptive rather than rigid. The system continuously monitors movement direction and distance in the proximity state and dynamically determines operation completion based on whether the operating object moves toward or away from the touch panel, allowing flexible and intuitive user interaction without strict predetermined time requirements.

Inventive Principle:
Principle #15Dynamics

AI summary

An information processing apparatus can recognize a first operation made up of a first input and a second operation made up of the first input and an input that follows after the first input. Input by an operating object is detected, starts a response corresponding to the first operation after the first input from the operating object is detected, regardless of existence of any input to follow after the first input, in a case that information relating to movement of the operating object moving in a direction parallel to an input subject face, which is the subject for the operating object to perform the first input, satisfies a predetermined condition.
