1Productivity
If conventional touch-sensitive surface methods are used to manipulate user interface objects, then basic functionality is provided, but interaction becomes cumbersome and inefficient, increasing interaction time and energy consumption
Solution Approach 1:
The patent changes the parameter of touch input from binary (touch/no touch) to continuous intensity levels. The touch-sensitive surface detects and responds to varying intensities of user input, enabling a single continuous interaction to perform multiple operations or provide progressive feedback, thereby reducing the number of separate inputs required and improving interaction efficiency
Solution Approach 2:
The patent implements visual and haptic feedback mechanisms that respond to touch intensity in real-time. As users apply increasing pressure or intensity to a touch input, the system provides corresponding visual changes (such as scaling icons) and haptic feedback (vibrations or resistance changes), allowing users to understand system response and adjust their input accordingly, reducing uncertainty and interaction time
2Use of energy by moving object
If conventional touch-sensitive surface methods are used to manipulate user interface objects, then basic functionality is provided, but the number of user inputs increases, leading to energy wastage in battery-operated devices
Solution Approach 1:
The patent transforms the touch input system from requiring multiple discrete inputs to accepting a single continuous intensity-based input. By detecting the intensity parameter of user touch, the system can interpret different intensity levels as different commands or provide progressive disclosure of options, reducing the total number of inputs required and thereby conserving battery energy
Solution Approach 2:
The patent introduces dynamic responsiveness where the system adapts its behavior based on the real-time intensity of user input. The interface elements dynamically change their state (visual appearance, functionality) in response to varying touch intensity, allowing the system to respond appropriately to user intent without requiring multiple sequential inputs, thus reducing energy consumption

AI summary
An electronic device displays a control user interface that includes a plurality of control affordances. The device detects a first input directed to a location that corresponds to a first control affordance, of the plurality of control affordances. In response to detecting the first input, if the first input meets control toggle criteria, the device toggles a function of a control that corresponds to the first control affordance. And if the first input meets enhanced control criteria, the device displays modification options for the control that correspond to the first control affordance. While displaying the modification options, the device detects a second input that activates a modification option of the modification options and, accordingly, modifies the control that corresponds to the first control affordance.
