Dual Touch Panel Input Control for Display Target Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current input methods on touch panels, such as smartphones and portable game devices, can be confusing and prone to user errors, particularly when trying to move or scroll through multiple pages or items, as they often require precise finger movements that can lead to unintended actions or malfunctions.
Innovation Solution
An input control system that utilizes both a front and rear touch panel, allowing users to designate a target for movement or deformation with one hand while scrolling or switching pages with the other, using distinct input entries to maintain clarity and reduce errors, and incorporating visual feedback to confirm mode changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single touch panel is used for all input operations, then the device structure remains simple, but user operations become confused and error-prone when needing to both select targets and scroll through lists
Solution Approach 1:
The touch panel is divided into two independent functional zones: a front touch panel for selecting display targets and a rear touch panel for scrolling through lists. This segmentation allows users to perform different operations simultaneously without confusion, as each panel has a dedicated function. The front panel handles target selection while the rear panel handles navigation, eliminating operational ambiguity.
Solution Approach 2:
The patent adds a spatial dimension by introducing a second touch panel in a different location (rear side) compared to the front panel. This dimensional separation allows users to intuitively distinguish between target selection (front) and scrolling operations (rear), improving operational clarity without requiring complex software modes.
2Measurement precision
If precise finger movements are required for input operations, then input accuracy improves, but user friendliness decreases due to difficulty in performing operations while holding the device
Solution Approach 1:
By segmenting the input functions into two separate panels, the system allows users to hold the device with one hand while operating the rear panel with the other hand. The rear touch panel is specifically designed for scrolling operations, enabling users to navigate lists without needing precise finger movements on a single panel while maintaining device grip stability.
3Device complexity
If only one touch panel is used, then the device structure remains simple, but unintended actions and malfunctions increase when users need to perform multiple operations
Solution Approach 1:
The touch panel is segmented into front and rear panels with distinct functions. The front panel handles target selection while the rear panel handles scrolling. This segmentation prevents unintended actions because each panel is dedicated to specific operations, eliminating ambiguity about which operation should be performed based on finger position and movement direction.
Solution Approach 2:
The system uses the spatial separation between front and rear panels as an intermediary mechanism to distinguish between different input intentions. The physical location of the finger on either the front or rear panel serves as an intermediary signal that disambiguates between target selection and scrolling operations, preventing malfunctions.

AI summary
A game device includes: a display control unit that displays a plurality of display targets on a display screen of a display device; an input acquiring unit that acquires a position of input from a front touch panel or a rear touch panel, which can detect input on the display screen; and a movement control unit that defines as a target to be moved a display target displayed by the display control unit on the display screen at a position corresponding to the position of a first input entry acquired by the input acquiring unit, and operative to scroll a display target other than the target to be moved in accordance with a second input entry acquired by the input acquiring unit while keeping the display position of the target to be moved at the position of the first input entry.
