Touch Panel Control Reducing Touch Operations via Dynamic Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current touch panel systems require multiple touches to select and determine an option, especially when guidance is not displayed, making the operation more cumbersome.
Innovation Solution
A display control apparatus that reduces the number of touch times by automatically setting a touched option to a selected status without guidance, allowing for option determination with a single touch, regardless of the option's selected status, when guidance is not displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If guidance is not displayed to simplify the interface, then the interface becomes cleaner and easier to understand, but the number of touch operations increases making the operation more cumbersome
Solution Approach 1:
The patent applies dynamics by making the operation mode adaptable based on the current state. When guidance is displayed, the system requires selection before determination (two touches). When guidance is not displayed, the system allows direct determination (one touch). This dynamic adjustment of operation requirements based on display state resolves the contradiction between interface simplicity and operational efficiency.
Solution Approach 2:
The patent changes the operational parameters (number of required touches) based on the guidance display parameter. When guidance display is ON, the system requires two touches (selection + determination). When guidance display is OFF, the system requires only one touch (direct determination). This parameter change approach allows the system to optimize for either interface clarity or operational speed depending on the guidance state.
2Reliability
If two-touch operation (selection + determination) is required for all options, then the operation is consistent and reliable, but the operation becomes unnecessarily complex when guidance is not displayed
Solution Approach 1:
The patent makes the operation complexity dynamic based on guidance display state. When guidance is displayed, the two-touch process (selection + determination) ensures reliable and consistent operation. When guidance is not displayed, the system dynamically simplifies to a single-touch determination, reducing unnecessary complexity while maintaining reliability through the consistent application of the rule.
Solution Approach 2:
The patent applies preliminary action by pre-setting the operational mode based on the guidance display state. When guidance is not displayed, the system is pre-configured to allow direct determination without requiring a separate selection step, thus avoiding unnecessary operational complexity while maintaining reliability through consistent state-based behavior.
3Loss of information
If guidance is displayed to assist users, then user understanding is improved, but the screen space is reduced and the operation steps are increased
Solution Approach 1:
The patent applies dynamics by making the guidance display state-dependent. When the option is in a selected state, guidance is displayed to provide user understanding without permanently occupying screen space. When the option is not selected, guidance is not displayed, maximizing screen space availability. This dynamic display approach balances information provision with space utilization.
4Measurement precision
If the system requires selecting an option first before determining it, then the operation is precise and controlled, but the number of touches increases making the operation slower
Solution Approach 1:
The patent makes the selection requirement dynamic based on guidance display state. When guidance is displayed, the system requires explicit selection before determination to ensure precision. When guidance is not displayed, the system allows direct determination, assuming the touched option is the intended target, thus improving operation speed while maintaining adequate precision through context-aware behavior.

AI summary
When an item is selected with a touch from an item list, if display of a guidance is set to ON, the item is selected by a first touch and the guidance is displayed to view another item. A determination operation is performed by a second touch to the same item. If the display of the guidance is set to OFF, a determination operation of an touched item is performed by the first touch without displaying the guidance. Thus, when it is set that the guidance is not displayed, inconvenience that a user needs to touch the same option twice even the guidance display is not required to shift a screen to a sub-screen can be eliminated, and increase of troublesomeness for a shift operation to the sub-screen can be prevented.
