Mobile Terminal Virtual Key Processing with Auxiliary Sensing Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile terminals with touch screens, users often inadvertently trigger multiple virtual buttons simultaneously, leading to incorrect processing due to the lack of differentiation in touch sensitivity between buttons and the surrounding area.
Innovation Solution
The implementation of a touch-sensitive auxiliary sensing area on the touch panel, which adjusts the processing priority of virtual buttons based on their distance from the sensing area, reducing misoperations by identifying the most distant button as the intended trigger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If virtual buttons are implemented on a touch screen without auxiliary sensing areas, then the device complexity is reduced and ease of manufacture is improved, but the reliability of button trigger detection deteriorates due to inability to differentiate between intentional and inadvertent touches
Solution Approach 1:
The touch panel is segmented into multiple functional zones: virtual button areas and auxiliary sensing areas. Each zone has distinct detection characteristics, allowing the system to differentiate between intentional button presses and inadvertent touches based on which zone is activated.
Solution Approach 2:
The auxiliary sensing area acts as an intermediary element that indirectly indicates the user's intent. When a user's finger approaches or touches near a virtual button, the auxiliary sensing area detects this proximity or light contact, serving as a mediator to predict the intended button press before actual contact occurs.
2Measurement precision
If the touch panel uses uniform sensitivity across all areas, then the ease of operation is improved and device complexity is reduced, but the measurement precision of touch intent deteriorates
Solution Approach 1:
Different regions of the touch panel are assigned different detection sensitivities and functions. Virtual button areas are configured for definitive press detection, while auxiliary sensing areas use proximity or light touch detection. This local differentiation enables precise measurement of user intent based on touch location and characteristics.
Solution Approach 2:
The auxiliary sensing area detects touches that are partial or incomplete (light touches or proximity without full contact). By detecting these partial actions, the system can infer user intent before a complete button press occurs, improving measurement precision of intended actions.
3Productivity
If no auxiliary sensing area is provided, then the device complexity is reduced and manufacturing is easier, but the productivity of user operations deteriorates due to incorrect processing requiring user correction
Solution Approach 1:
The auxiliary sensing area performs preliminary detection of user intent before the actual button press occurs. By detecting proximity or light touches in advance, the system can prepare for the intended operation, reducing the need for user correction and improving overall operation productivity.
Solution Approach 2:
The system uses feedback from the auxiliary sensing area to adjust processing decisions. When the auxiliary sensing area detects a touch pattern consistent with intentional button pressing, the system confirms the operation; otherwise, it can prevent incorrect processing, creating a feedback loop that improves operational accuracy.
