Terminal Slide and Hold Gesture for Error Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find the display and operation of guidance images for operation confirmation in terminals to be bothersome, especially when trying to operate quickly.
Innovation Solution
The terminal receives a slide operation of an image from a first position to a second position and an operation for a specific process when a finger is held in the second position without release for a certain period of time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a confirmation screen with text 'Do you want to switch?' is displayed to prevent erroneous operation, then reliability is improved, but ease of operation deteriorates and user convenience is reduced
Solution Approach 1:
The patent changes the operational parameters from simple tap to slide gesture combined with hold duration. This parameter change maintains reliability by requiring a more complex input pattern that is less likely to be accidental, while still preserving ease of operation through intuitive swipe gestures that users are already familiar with from common UI interactions.
Solution Approach 2:
Instead of adding a confirmation screen that requires additional taps (adding steps), the patent inverts the approach by using a single continuous gesture (slide and hold) that combines the confirmation action into one fluid motion. This eliminates the need for separate confirmation screens while maintaining the preventive function against erroneous operations.
2Reliability
If a confirmation screen with text 'Do you want to switch?' is displayed to prevent erroneous operation, then reliability is improved, but productivity deteriorates due to additional operation time
Solution Approach 1:
The patent applies preliminary action by having the user perform a slide gesture that inherently indicates intent before the hold duration is enforced. The slide motion prepares the system to recognize the user's intention, and the subsequent hold duration confirms it, creating a streamlined process that prevents erroneous operations without requiring separate confirmation screens that would slow down productivity.
Solution Approach 2:
The patent merges the confirmation function into the same gesture sequence used for normal operations. By combining the slide (indicating direction/intent) and hold (indicating confirmation/duration) into one continuous action, the system eliminates the need for separate confirmation screens, thereby maintaining reliability while improving operation speed and productivity.
3Reliability
If multiple tap operations are required for confirmation, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent introduces dynamics by using a continuous gesture with temporal variation rather than discrete static taps. The slide gesture provides directional information, while the hold duration provides temporal confirmation. This dynamic approach maintains reliability through multi-stage verification while reducing operational complexity by using natural, fluid hand movements that feel more intuitive than multiple separate taps.

AI summary
A terminal receives a slide operation of an image displayed on a display from a first position to a second position and when a finger is held in the second position without being released from the display for a certain period of time, receives an operation for a specific process.
