Touch Layer Scrolling via Manipulating Body Count
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complexity in searching for desired display items from multiple layers on information processing devices, as existing methods like drag and flick manipulation can lead to difficulty in maintaining focus and efficiency, especially when display items are divided into numerous layers.
Innovation Solution
An information processing device that detects the number of manipulating bodies and their movement direction and amount to dynamically switch between layers, allowing for efficient scrolling of display items by changing the number of bodies detected, thereby enabling seamless navigation through multiple layers without complex manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If drag manipulation is used to scroll-display display items on each layer, then the search for desired display items can be performed, but the manipulation complexity increases significantly when display items are divided into multiple layers
Solution Approach 1:
The patent merges the layer switching operation with the scroll display operation by detecting the number of manipulating bodies. When one body is detected, scroll display occurs on the current layer; when multiple bodies are detected, layer switching occurs. This combines what were previously separate operations (drag manipulation for scrolling and separate switching for layer changes) into a unified interaction model, reducing manipulation complexity while maintaining ease of searching across layers
Solution Approach 2:
The detection unit and display control unit work together to make the touch panel serve multiple functions simultaneously - it can detect both scroll display commands and layer switching commands through the number of manipulating bodies. This multi-functionality allows a single interface to handle both operations without requiring separate manipulation modes, thereby reducing the complexity burden on users
2Productivity
If flick manipulation is used to scroll-display display items, then the number of drag manipulations is reduced, but the display screen changes intensively and the focused display item is easily lost
Solution Approach 1:
The patent applies local quality by differentiating the scroll display behavior based on the number of manipulating bodies detected. When one body is detected, the system performs scroll display on the current layer with preserved focus. When multiple bodies are detected, the system switches to a different layer. This localized differentiation of behavior based on detection parameters allows efficient searching while maintaining focus on relevant display items
3Adaptability or versatility
If display items are divided into a plurality of layers, then the organization and search capability are improved, but the manipulation complexity and difficulty of switching between layers increases
Solution Approach 1:
The number of manipulating bodies serves as an intermediary parameter that mediates between the user's input and the layer switching action. Instead of requiring direct layer switching manipulation (which is complex), the system uses the count of manipulating bodies as an intermediary to determine which layer to display. This intermediary mechanism simplifies the user interface while maintaining the versatility of multi-layer search capability

AI summary
An information processing device includes a display panel for displaying display items belonging to a predetermined layer among display items divided into a plurality of layers, a manipulating body detection unit for detecting the number of manipulating bodies moving on a touch panel along with a movement direction and a movement amount of the manipulating body, and a display control unit for performing display control so that display items belonging to the predetermined layer are scroll-displayed on the basis of detection results of the movement direction and the movement amount if a movement of manipulating bodies whose number corresponds to the predetermined layer is detected, display items belonging to another layer are displayed if a movement of manipulating bodies whose number corresponds to the other layer is detected, and the display items belonging to the other layer are scroll-displayed on the basis of detection results.
