Soft Key Icon Modification for Mobile Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile device confirmation methods require users to navigate away from the main display or use both hands to confirm actions, obstructing the screen and complicating one-handed operation.
Innovation Solution
Displaying a confirmation message and soft key icons below the main display window, allowing users to confirm actions using updated soft key icons without leaving the active window, enabling one-handed operation and maintaining visibility of the main screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a message box is displayed to confirm user action, then user confirmation is obtained, but the main display screen is covered and user interaction is blocked
Solution Approach 1:
The confirmation message is moved from a full-screen overlay (2D plane covering the display) to the bottom portion of the screen, creating a spatial arrangement where the message exists in a different dimensional zone. This allows the confirmation message to be displayed without blocking the main display content, as the message and content occupy different vertical zones on the screen.
2Reliability
If traditional confirmation buttons are used, then user confirmation is obtained, but both hands are required for operation
Solution Approach 1:
The confirmation buttons are merged with the existing soft key interface elements that are already positioned at the bottom of the screen. Instead of creating separate confirmation controls that require stylus input or navigation, the soft keys themselves are repurposed to provide confirmation responses, combining the navigation and confirmation functions into a single integrated control mechanism accessible by one hand.
3Loss of information
If the display window is resized to accommodate confirmation message, then message visibility is improved, but the main display content area is reduced
Solution Approach 1:
The display screen is divided into different functional zones with different qualities: the bottom portion is dedicated to confirmation messages and controls, while the upper/main portion maintains its full quality for content display. This local differentiation allows the confirmation message to be clearly visible in its designated zone without reducing the area or quality of the main display content area.

AI summary
Prompting user confirmation of an action in a display window on a display of a mobile electronic device including displaying a pair of soft key icons, receiving a request to initiate an action from a user and displaying a confirmation message to confirm that a user wishes to proceed with the action. When the confirmation message is displayed, the pair of soft key icons are modified to create a pair of updated soft key icons. The receiving of the request may include detection of a soft key event. The updated soft key icons provide a first response and a second response to the confirmation message for selection by the user. The soft key icons and updated soft key icons may be displayed at the bottom portion of the display in a manner that does not obstruct the display window.
