Dual Touch Panel Input Continuity Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with dual touch panels struggle to accurately determine the continuity of touch operations across the screens, especially when users perform operations in unstable conditions, leading to incorrect processing of intended user actions.
Innovation Solution
An input apparatus and method that includes a display unit, input detecting unit, position acquiring unit, start-position estimating unit, and continuity determining unit, which estimates the start position of a touch operation on one screen based on the speed and direction of the previous operation and determines if the subsequent touch operation on the other screen is a continuation of the previous one, using coordinate data and timing information to ensure accurate continuity assessment.

1Volume of moving object
If the electronic device uses a hinge mechanism between two touch panels, then the device can be collapsed to save space, but it becomes difficult to accurately determine whether touch operations on different screens are continuous
Solution Approach 1:
The system performs preliminary actions by detecting and recording the end position and timing of touch operations on the first screen before the user completes the operation. This allows the system to prepare for continuity determination by having the end position data ready, enabling accurate matching when the user touches the second screen.
Solution Approach 2:
The system provides feedback by comparing the start position of the touch operation on the second screen with the previously detected end position on the first screen. This feedback mechanism determines whether the operations are continuous, allowing the system to correctly interpret user intent across the hinge mechanism boundary.
2Productivity
If the user performs touch operations quickly across two screens, then operation efficiency increases, but the time period between operations may cause incorrect determination of operation continuity
Solution Approach 1:
The system performs preliminary detection and recording of the end position and timing of touch operations on the first screen. By having this data prepared in advance, the system can quickly compare it with the start position on the second screen, enabling accurate continuity determination even when operations occur rapidly.
Solution Approach 2:
The system replaces manual judgment of operation continuity with an automated coordinate-based detection system. By using the position acquiring unit to precisely track touch coordinates and timing, the system objectively determines continuity based on spatial and temporal relationships rather than subjective interpretation, enabling accurate detection of rapid operations.
