Touch Display Interface with Sequential Setting Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch display systems face issues where unintended user contacts can execute tasks or change settings, leading to erroneous task executions, such as incorrect printing settings.
Innovation Solution
An information processing apparatus with a touch display that displays a first GUI for task selection and, upon touch-down, sequentially reveals setting values based on the continuation of the operation, executing the task only when the user completes the intended move operation and not executing it if a touch-up occurs before completion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch display accepts direct touch operations to execute tasks, then ease of operation is improved, but reliability deteriorates due to unintended contacts causing erroneous task execution
Solution Approach 1:
The system performs preliminary actions by displaying a second GUI with setting values before the task is executed. When a touch-down operation is detected, the system sequentially displays setting values (number of copies, paper size, color settings) based on the continuation amount of the touch operation, allowing the user to confirm settings before final execution.
Solution Approach 2:
The system dynamically changes the display content based on the continuation amount of the touch operation. As the user maintains the touch, different setting values are sequentially displayed, transforming the static touch interface into a dynamic settings confirmation process that prevents erroneous execution.
2Reliability
If setting values are displayed sequentially based on continuation amount, then reliability is improved by preventing unintended execution, but device complexity increases
Solution Approach 1:
The touch operation is segmented into distinct phases: touch-down operation, continuation phase with sequential display of setting values, and touch-up operation. Each phase triggers specific system responses, dividing the complex interaction into manageable segments that improve reliability without requiring complex hardware.
Solution Approach 2:
The continuation amount of the touch operation serves as an intermediary parameter that mediates between the user's touch input and the system's response. By using the duration/amount of continuous touch as a trigger mechanism, the system avoids complex button presses or confirmation dialogs while maintaining reliability.
3Loss of information
If multiple setting values are displayed during touch continuation, then information completeness is improved, but loss of time increases due to sequential display
Solution Approach 1:
The system maintains continuous display of setting values throughout the touch continuation period. Instead of requiring the user to navigate through multiple screens or wait for sequential page transitions, all relevant setting values (number of copies, paper size, color settings) are continuously displayed and updated based on the touch continuation amount, allowing the user to review all information simultaneously.

AI summary
An information processing apparatus includes a display control unit that performs control to display, on a touch display, a first graphical user interface (GUI) corresponding to a task and to display a second GUI different from the first GUI in a case where a touch-down operation on the first GUI has been performed, and to perform control, in a case where a continuing operation has started following the touch-down operation, to sequentially display a plurality of setting values different in type with respect to the task based on an amount of continuation of the continuing operation before the continuing operation is completed, and a task control unit that performs control to execute the task in a case where the continuing operation has completed and not to execute the task in a case where a touch-up operation has been performed before the continuing operation is completed.
