Solution Overview

Problem

Existing methods for managing concurrently open applications on portable electronic devices with touch-sensitive surfaces, such as smartphones, are cumbersome, inefficient, and energy-intensive, leading to cognitive burden and battery drain.

Innovation Solution

Implementing methods and interfaces on multifunction devices with touch-sensitive displays that allow for efficient selection and display of concurrently open applications through gestures and views, including three-dimensional stacks, predefined areas, and size variations, to manage and switch between applications quickly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple applications are displayed concurrently on small screens, then application visibility and management capability improve, but screen real estate and interface complexity increase

Engineering Contradiction:
Improveapplication managementVSAvoidscreen real estate
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent transforms the traditional two-dimensional grid layout into a three-dimensional stack arrangement where applications are organized vertically. This dimensional change allows multiple applications to be displayed without increasing horizontal screen occupancy, resolving the contradiction between application visibility and screen real estate utilization.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the application display into individual stacked elements, each representing a separate application. This segmentation allows users to manage applications independently while maintaining compact screen usage, as each segment can be individually accessed, minimized, or closed without affecting others.

Inventive Principle:
Principle #1Segmentation

2Productivity

If conventional application switching methods are used, then application management is achieved, but user efficiency decreases and cognitive burden increases

Engineering Contradiction:
Improveuser efficiencyVSAvoidcognitive burden
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent introduces curved transition animations when switching between applications, creating a smooth visual flow that guides user attention. This curved transition reduces cognitive burden by providing intuitive visual cues about application switching, eliminating the need for users to mentally track application states.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

Instead of requiring users to navigate through multiple menus or screens to switch applications, the patent inverts the approach by making applications directly accessible through the stack display. Users can tap any application in the stack to immediately switch to it, reversing the traditional navigation hierarchy and significantly improving user efficiency.

Inventive Principle:
Principle #13The other way round (Inversion)

3Use of energy by moving object

If applications are managed sequentially one at a time, then energy consumption is reduced, but time management and switching efficiency worsen

Engineering Contradiction:
Improvebattery powerVSAvoidapplication switching time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The patent displays thumbnails and previews of multiple applications simultaneously in the stack, allowing users to anticipate upcoming actions and make informed decisions about which application to switch to next. This preliminary visualization reduces unnecessary application switching and keeps applications in memory longer, improving time management while maintaining energy efficiency.

Inventive Principle:
Principle #10Preliminary action

4Measurement precision

If detailed application information is displayed, then application selection accuracy improves, but interface complexity and processing requirements increase

Engineering Contradiction:
Improveapplication selection accuracyVSAvoidinterface complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies different levels of detail to different parts of the interface. The stack thumbnails provide summary information at a glance, while full application windows display complete details. This local quality differentiation allows accurate application selection through visual cues without requiring complex interface elements throughout the entire system.

Inventive Principle:
Principle #3Local quality

AI summary

An electronic device detects a gesture on a touch-sensitive display. In response to detecting the gesture on the touch-sensitive display, when the gesture is a first swipe gesture in a first direction, the device displays a plurality of open application icons that corresponds to at least some of a plurality of concurrently open applications. When the gesture is a second swipe gesture in a second direction distinct from the first direction, the device displays one or more settings icons. In some embodiments, the first direction is a horizontal direction. In some embodiments, the second direction is an upward direction.
