Pinch Gesture Page Arrangement for Print Setting Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data processing apparatuses, such as image forming devices, do not intuitively link touch operations to corresponding printing settings, leading to user misunderstandings and potential erroneous operations, especially when changing between double-side and single-side printing or combining/dividing files.
Innovation Solution
A data processing apparatus with a display portion, touch sensor, and control portion that interprets pinch operations to set page arrangements, allowing users to change printing settings and file configurations through intuitive touch gestures, such as pinching out to separate pages or combine files, closely mimicking the output result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional touch operations (linking/separating preview images) are used, then page arrangement settings can be changed, but users may misunderstand the operations and cause erroneous settings
Solution Approach 1:
The patent inverts the conventional touch operation logic by using pinch-in to separate pages and pinch-out to combine pages, which is opposite to the intuitive expectation but achieves the desired setting accuracy. This resolves the contradiction by prioritizing setting accuracy over intuitive operation, as the patent accepts that users may need to learn the inverted logic to achieve reliable settings.
Solution Approach 2:
The patent implements feedback by displaying the selected pages or files in a list view after the pinch operation, allowing users to confirm the setting result. This feedback mechanism helps users verify that the operation produced the expected outcome, thereby improving setting accuracy even though the operation itself may not be immediately intuitive.
2Reliability
If pinch-in operation is used to combine pages, then file combination setting is achieved, but the operation counter-intuitively combines rather than separates
Solution Approach 1:
The patent applies inversion by making pinch-in result in page separation and pinch-out result in page combination, which is opposite to the intuitive expectation. This resolves the contradiction by accepting the counter-intuitive operation in exchange for achieving accurate file combination settings, as the patent prioritizes setting accuracy over immediate intuitiveness.
3Reliability
If pinch-out operation is used to separate pages, then file separation setting is achieved, but the operation counter-intuitively separates rather than combines
Solution Approach 1:
The patent applies inversion by making pinch-out result in page separation and pinch-in result in page combination, which is opposite to the intuitive expectation. This resolves the contradiction by accepting the counter-intuitive operation in exchange for achieving accurate file separation settings, as the patent prioritizes setting accuracy over immediate intuitiveness.

AI summary
A data processing apparatus includes a display portion, a control portion including a display control portion for causing the display portion to display a preview image of output target data, a touch sensor for receiving, on the display portion, a user operation for performing output setting for the output target data concerning the preview image, an output portion for outputting the output target data based on the output setting, and a control portion for, in a state where the display control portion arranges objects in page unit sequentially to be displayed as the preview image, when the touch sensor receives a predetermined pinch operation for the objects, performing page setting concerning the objects to be operated.
