Live Previews for Multitasking State Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Web applications with multiple activities often result in cluttered and confusing user interfaces due to the lack of visual representation for background activities, which are not accurately reflected by traditional user interface controls like tabs or lists.
Innovation Solution
Implementing a multitask preview interface that generates real-time, visual live previews for activities, even those hidden from the user's perspective, allowing users to switch between them seamlessly by selecting from a scaled-down representation of the current state of each activity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional user interface controls like tabs or lists are used to manage multiple activities, then the user interface achieves basic functionality for switching between activities, but the interface becomes cluttered and confusing
Solution Approach 1:
The patent creates visual copies (previews) of background activities that are displayed within the foreground activity interface. These previews are scaled-down representations that show actual content from background activities, allowing users to switch between activities by interacting with the previews rather than traditional tabs. This reduces interface clutter while maintaining ease of operation.
Solution Approach 2:
The patent adds a new visual dimension to activity management by displaying previews that occupy a portion of the foreground activity's display area. Instead of using separate tabs or lists that add horizontal or vertical complexity, the previews are integrated into the existing display space, showing scaled-down versions of background activities within the foreground context.
2Loss of information
If limited information is presented for background activities using traditional controls, then the interface remains simple, but users cannot accurately understand the current state of background activities
Solution Approach 1:
The patent creates visual copies (previews) of background activities that are displayed within the foreground activity interface. These previews are scaled-down representations that show actual content from background activities, allowing users to switch between activities by interacting with the previews rather than traditional tabs. This reduces interface clutter while maintaining ease of operation.
Solution Approach 2:
The patent uses visual characteristics including color, image, or other visual characteristics to differentiate between foreground and background activities. The previews display actual content from background activities with visual indicators that distinguish them from the foreground activity, providing clear state information without adding interface complexity.
Data Source
AI summary
Invoked states of one or more activities invoked in a web application is detected. The web application is configured to display, in a foreground, a current activity on a client device. On the client device, display of a multitask preview interface that includes one or more live previews is caused. Each live preview of the one or more live previews corresponds to an invoked state of an activity of the one or more activities. The one or more live previews includes a particular live preview that corresponds to a particular invoked state of a particular activity of the one or more activities. Selection of the particular live preview is detected. In response to detecting selection of the particular live preview, the current activity displayed in the foreground of the web application is switched to the particular state of the particular activity.
