Solution Overview

Problem

Existing user interfaces face challenges in improving the operability of double taps, as they often interrupt the tap sequence with warning messages, leading to missed detection of the second tap due to pop-up interruptions.

Innovation Solution

A user interface design that suspends the display of warning messages until the double-tap determination timer expires, prioritizing the transition to the double-tap processing screen and displaying warnings only after the second tap is confirmed, ensuring the user can complete the double-tap action without interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If warning messages are displayed immediately when detected, then users are notified of troubles promptly, but the double-tap operation may be interrupted causing missed detection of the second tap

Engineering Contradiction:
Improvedouble-tap detection accuracyVSAvoidwarning notification delay
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary detection of the first tap and starts a determination timer before displaying warning messages. This preliminary action allows the system to reserve time for detecting the second tap of the double-tap operation, ensuring that warning messages are not displayed during the critical detection period.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts the timing of warning message display based on the state of the determination timer. When the timer is running (indicating a potential double-tap is being detected), warning messages are suppressed. Once the timer expires without detecting a second tap, the system dynamically switches to displaying the warning message, thus adapting the notification behavior to the current operational context.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If pop-up messages are displayed during touch panel manipulation, then users are informed of system status, but the manipulation flow is interrupted reducing operability

Engineering Contradiction:
Improvedouble-tap manipulation flowVSAvoidwarning message visibility
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system applies preliminary anti-action by suppressing the display of warning messages when a double-tap operation is detected. This prevents the harmful effect of interrupting the user's manipulation flow with pop-up messages during the critical period when the second tap is being detected, ensuring smooth operation continuity.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The system performs preliminary detection of the tap sequence and determines whether it constitutes a double-tap before allowing warning messages to be displayed. This preliminary determination ensures that the manipulation flow is not interrupted by warning messages during the double-tap operation, while still maintaining the ability to display warnings when appropriate.

Inventive Principle:
Principle #10Preliminary action

AI summary

A manipulation panel (130) that is a user interface includes a display unit (133) that displays a screen, a touch panel (134) that detects a tap performed to the display unit (133), and an abnormality detector (190) that detects a situation, in which a message is displayed on the display unit (133), until the touch panel (134) detects a second tap constituting a double tap since detecting a first tap. Manipulation panel (130) displays a warning message about the situation detected by the abnormality detector (190) on the display unit (133) after the touch panel (134) detects the second tap.
