Document Navigation Mode Switching via Gesture Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current information processing systems, such as tablet devices, require cumbersome operations to navigate through multiple-page electronic documents, lacking an efficient method to switch between single-page and multi-page navigation modes.
Innovation Solution
An information processing apparatus with a screen, a receiving unit, and a processing mode changing unit that detects specific operations to switch between single-page and multi-page navigation modes, allowing users to change modes by maintaining a drag operation or using multi-touch gestures to move multiple pages at once.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If single-page navigation mode is used, then operation precision is maintained, but navigation efficiency deteriorates when needing to access pages far from current position
Solution Approach 1:
The system dynamically switches between single-page and multi-page navigation modes based on user gestures. The processing mode changing unit detects gesture characteristics (such as drag distance or gesture type) and automatically transitions between modes, allowing the system to adapt its behavior rather than being fixed in one navigation approach
Solution Approach 2:
The system changes the navigation parameter (page turn count) based on detected gesture characteristics. When a gesture indicates a larger drag distance or specific pattern, the system changes the parameter to turn multiple pages at once, thereby improving navigation efficiency for distant page access
2Productivity
If multi-page navigation mode is used, then navigation efficiency improves, but operation precision deteriorates for fine-grained page selection
Solution Approach 1:
The system provides dynamic control over navigation precision by allowing users to switch between modes. When precise page selection is needed, users can trigger single-page mode; when efficiency is prioritized, multi-page mode activates. This dynamic adaptability resolves the contradiction by making precision available on demand rather than being fixed
Solution Approach 2:
The navigation function is segmented into two distinct modes: single-page mode for precise selection and multi-page mode for efficient navigation. The processing mode changing unit manages these segments, allowing the system to select the appropriate segment based on user needs, thereby maintaining both precision and efficiency in different contexts
3Ease of operation
If gesture-based mode switching is added, then ease of operation improves, but device complexity increases
Solution Approach 1:
The gesture detection mechanism serves multiple functions: it detects both the initial mode-switching gesture and subsequent navigation gestures. By making the gesture detection system multi-functional, the patent reduces the need for separate detection mechanisms, thereby limiting the increase in device complexity while maintaining ease of operation
Solution Approach 2:
The system uses the user's own gesture characteristics (drag distance, gesture type) as the control signal for mode switching. Rather than requiring separate buttons or complex interfaces, the navigation gestures themselves serve as the mode-switching mechanism, simplifying the user interface while the gesture detection unit processes the information

AI summary
An information processing apparatus includes a screen, a receiving unit that receives an operation performed on the screen, a display that displays a document having multiple pages on the screen on a page-by-page basis, a processing mode changing unit that, upon detecting a predetermined first operation on the document displayed on the screen, changes from a first processing mode that moves one page at a time to a second processing mode that moves multiple pages, and a moving unit that, upon detecting a predetermined second operation in the second processing mode, moves multiple pages within the document. As the predetermined first operation, the processing mode changing unit detects continued detection of a first position where a drag operation has ended, or detects, while the first position is detected, an operation performed at a second position different from the first position.
