Touch Interface Stack Navigation for Battery Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for navigating between user interfaces on electronic devices with touch-sensitive surfaces are cumbersome, inefficient, and energy wasteful, particularly in battery-operated devices, and can be distracting with abrupt transitions.
Innovation Solution
The implementation of methods and interfaces that allow for faster and more efficient navigation between user interfaces by displaying a stack of user interface representations, detecting drag gestures and intensity changes of contacts on the touch-sensitive surface, and adjusting the speed and offset of user interface representations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional user interface navigation methods are used, then user interface transitions are achieved, but the navigation is cumbersome and inefficient with more user inputs required
Solution Approach 1:
The system displays a stack of user interface representations in advance, showing multiple interfaces simultaneously. This preliminary display allows users to see upcoming interfaces before fully transitioning to them, enabling faster navigation decisions and reducing the number of input steps required to navigate between interfaces.
Solution Approach 2:
The patent introduces a vertical stacking dimension to user interface navigation, where multiple interface representations are arranged in a vertical stack rather than requiring sequential horizontal transitions. This dimensional change allows users to navigate through interfaces more efficiently by interacting with the stack structure, reducing navigation time and input complexity.
2Productivity
If conventional user interface navigation methods are used, then interface transitions are completed, but energy is wasted particularly in battery-operated devices
Solution Approach 1:
By displaying multiple user interface representations in a stack in advance, the system prepares navigation options before full transition is needed. This reduces the time and energy required for each navigation event, as the target interface is already visible and ready for selection, eliminating the need for lengthy sequential transitions that consume battery power.
Solution Approach 2:
The system dynamically adjusts the display based on user interaction, showing different portions of the stack depending on the current state and user gestures. This dynamic behavior optimizes energy consumption by only rendering and processing the necessary interface representations, rather than maintaining all interfaces in full detail simultaneously, thus reducing power usage while maintaining fast navigation capability.
3Productivity
If conventional user interface transitions are used, then navigation between interfaces is achieved, but abrupt transitions are distracting and jarring for users
Solution Approach 1:
The stack display shows multiple user interface representations in advance, including the target interface that will be displayed next. This preliminary visibility allows users to mentally prepare for the transition and see the continuity between current and upcoming interfaces, reducing the abruptness and distraction of transitions while maintaining efficient navigation speed.
Solution Approach 2:
The stack of user interface representations acts as an intermediary between the current interface and the target interface. Instead of making abrupt direct transitions, the stack provides a visual buffer that shows the progression and relationship between interfaces, smoothing the transition experience and reducing user distraction while maintaining navigation efficiency.

AI summary
An electronic device with a touch-sensitive display displays, on a touch-sensitive display, a first view of a first application. While displaying the first view, the electronic device detects a swipe input from an edge of the touch-sensitive display. In response to detecting at least a first portion of the swipe input from the edge of the touch-sensitive display, the electronic device concurrently displays, on the touch-sensitive display, at least a first application view corresponding to a first application, a second application view corresponding to a second application, and a representation of a home screen user interface that includes representations of a plurality of application launch icons.
