Solution Overview

Problem

Portable electronic devices with touch-sensitive displays face challenges in efficiently managing limited screen space for multiple applications, as existing technologies do not effectively allow users to preview information from one application without opening it, especially in small form factors.

Innovation Solution

A method and apparatus that detects specific gestures on the touch-sensitive display to preview information from a second application without launching it, allowing users to control the amount of information displayed and optionally open the application with a single continuous gesture.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the device size is decreased to improve portability, then the screen space becomes more limited, but the ability to efficiently manage and preview multiple applications is worsened

Engineering Contradiction:
Improvedevice sizeVSAvoidapplication management efficiency
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent introduces a new spatial dimension for application preview by displaying a snapshot of the second application within the display area of the first application. This dimensional approach allows multiple applications to be visually accessed simultaneously without requiring additional physical device space, effectively resolving the contradiction between small device size and efficient multi-application management.

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

Solution Approach 2:

The patent employs a gesture detection mechanism as an intermediary between user input and application switching. By detecting specific gestures (such as sliding gestures from the edge of the display), the system provides an intuitive intermediate step that allows users to preview applications without fully opening them, thereby improving operation efficiency on compact devices.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If users open every application to view its information, then complete information access is achieved, but time consumption and operational complexity increase

Engineering Contradiction:
Improveinformation access completenessVSAvoidtime to access application information
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The patent implements preliminary action by displaying a snapshot (preview) of the second application's information before the user actually opens the application. This advance viewing capability allows users to assess whether they need to fully open the application, thereby reducing unnecessary application launches and saving time while still providing access to essential information.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies partial action by providing a partial view (snapshot) of the application information rather than requiring the full application to be opened. This partial information display is sufficient for many user needs, reducing the time and resources required while maintaining adequate information access.

Inventive Principle:
Principle #16Partial or excessive action

3Loss of information

If multiple applications are displayed simultaneously to improve information access, then screen space utilization becomes insufficient, but the interface complexity increases

Engineering Contradiction:
Improvemulti-application information visibilityVSAvoidinterface complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the display area into different functional zones: the primary display area for the active application and an overlay region for the application snapshot. This segmentation allows multiple applications to be visually represented simultaneously while maintaining clear visual hierarchy and reducing interface complexity through spatial organization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a nested structure where the snapshot of the second application is displayed within the display area of the first application. This nesting approach allows efficient use of limited screen space while maintaining a clean interface, as the preview is contained within the existing display boundaries rather than requiring separate display regions.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A method includes displaying information associated with a first application on a touch-sensitive display of an electronic device. A gesture is detected on the touch-sensitive display, which gesture indicates a request to display information associated with a second application. At least part of the information associated with the second application is displayed without opening the second application.
