Engineering Contradiction Analysis
1Productivity
If conventional touch-sensitive surface manipulation methods are used, then user interface operations can be performed, but the operations are cumbersome and inefficient, leading to increased energy consumption
Solution Approach 1:
The system performs preliminary actions by displaying preview areas and visual feedback before the user completes the manipulation gesture. This allows users to see the intended result beforehand, reducing the need for corrective gestures and improving overall efficiency while reducing energy consumption.
Solution Approach 2:
The system implements continuous visual and haptic feedback during touch gestures, including dynamic visual feedback that changes based on gesture progress and intensity. This real-time feedback helps users understand system response immediately, reducing manipulation time and energy consumption.
2Ease of operation
If conventional touch-sensitive surface manipulation methods are used, then user interface operations can be performed, but the number and complexity of required user inputs increase
Solution Approach 1:
The system dynamically adapts the user interface based on gesture characteristics, displaying different preview areas and visual feedback depending on the type, intensity, and progression of the touch gesture. This dynamic response simplifies user interaction by providing context-appropriate information without requiring users to understand complex interface rules.
Solution Approach 2:
The system uses color and visual appearance changes to convey different states and information during manipulation. Visual feedback elements change appearance based on gesture progress and system state, providing intuitive cues that simplify user understanding without adding operational complexity.
3Loss of time
If conventional touch-sensitive surface manipulation methods are used, then basic user interface operations can be performed, but the time required for operations increases, wasting energy
Solution Approach 1:
The system displays preview areas and visual feedback during the manipulation gesture itself, allowing users to see the intended result before completing the gesture. This eliminates the need for separate actions to view or confirm operations, reducing both time and energy consumption.
Solution Approach 2:
The system maintains continuous visual and haptic feedback throughout the manipulation gesture, ensuring that useful information is always available to the user. This continuous feedback reduces hesitation and correction actions, thereby reducing operation time and energy consumption.

AI summary
An electronic device with a display and a touch-sensitive surface: displays a first user interface that includes a plurality of selectable objects; while a focus selector is at a location that corresponds to a respective selectable object, detects an input that includes detecting a contact on the touch-sensitive surface; and in response to detecting the input: in accordance with a determination that detecting the input meeting input criteria, including a criterion that is met when the contact meets a respective input threshold, displays a menu that includes contact information for the respective selectable object overlaid on top of the first user interface; and in accordance with a determination that detecting the input includes detecting a liftoff of the contact without meeting the input criteria, replaces display of the first user interface with display of a second user interface.
