Touchscreen Drag Mode Switching for Multi-Action Item Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panel operating methods limit the flexibility of drag operations, restricting them to specific directions based on the orientation of the list, which restricts the ability to perform multiple alternative processes on selected items.
Innovation Solution
A data processing device with a displaying unit, operation receiving unit, and screen generating unit that evaluates user operations and switches modes to allow drag operations in different directions, enabling flexible operation by transitioning between first and second modes based on drag direction and user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the drag operation direction is controlled by the list orientation, then the operation logic is simplified, but the flexibility and freedom of drag operation is reduced
Solution Approach 1:
The patent applies dynamics by making the operation mode switchable between first mode and second mode based on user interaction. The system transitions from a static operation mode to a dynamic one where the operation evaluating unit changes modes in response to drag operations, allowing the drag direction interpretation to adapt based on the current mode state rather than being fixed by list orientation
Solution Approach 2:
The patent changes the parameter of operation interpretation by switching between two distinct modes. In the first mode, drag operations are evaluated based on list orientation, while in the second mode, the same drag operations are evaluated differently to enable alternative processes. This parameter change allows the system to provide both simplified logic and flexible operation
2Ease of operation
If drag operation is limited to specific directions based on list arrangement, then the operation evaluation is straightforward, but the ability to perform multiple alternative processes is restricted
Solution Approach 1:
The patent implements multi-functionality by enabling the same drag operation interface to serve multiple purposes through mode switching. The operation evaluating unit can interpret identical drag operations differently depending on the mode, allowing users to access both default processes and alternative processes through the same interaction mechanism, thus providing universal access to multiple functions
3Reliability
If the operation mode is fixed based on list direction, then the system behavior is predictable, but the user freedom in drag operation is limited
Solution Approach 1:
The system transitions from fixed predictable behavior to dynamic adaptive behavior. The operation evaluating unit monitors drag operations and switches modes based on detected interaction patterns, allowing the system to maintain predictability within each mode while providing overall flexibility through mode transitions. This dynamic adaptation resolves the contradiction between reliability and user freedom
Data Source
AI summary
A data processing device comprises: a displaying unit that displays various different screens; an operation receiving unit, which is layered on the displaying unit, that receives operation inputted from a user on the screen; an operation evaluating unit that evaluates contents of the operation by the user on the operation receiving unit; and a screen generating unit that generates a screen including a operation object, and changes the screen in response to the contents of an operation. The operation evaluating unit switches its mode from first mode of a default state to a second mode in response to a drag operation in the lengthwise direction of the operation object on the operation object on the screen, and evaluates an identical drag operation in a direction that is different from the lengthwise direction of the operation object to be different instruction operations between the first mode and the second mode.
