Smart TV Application Launch Preview via Picture-in-Picture Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart TVs experience slow application launch times, particularly during the cold-start of applications, which can frustrate users due to the lengthy wait before the application interface is displayed.
Innovation Solution
A method that displays a first user interface with application icons, determines if the focus on a target icon is held for a preset time period, and then updates the interface to show a display window of the target application in Picture in Picture (PIP) mode, allowing the user to preview the application interface before launching it in full-screen mode upon confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the application is launched directly in full-screen mode, then the application can be displayed completely, but the launch time is long and the user perceives slow loading
Solution Approach 1:
The patent applies preliminary action by displaying a preview of the application interface in a small window before the user confirms to launch the application in full-screen mode. This allows the application to start loading and rendering in the background while the user waits, reducing the perceived launch time because the user sees content appearing before the full launch is complete.
2Loss of information
If the application interface is displayed in a small window for preview, then the user can see the application content beforehand, but the interface complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the display into two separate interfaces: a first user interface showing application icons and a small preview window, and a second user interface showing the full application. This segmentation allows the preview functionality to be added without completely redesigning the main interface structure, thus managing complexity while providing content visibility.
Solution Approach 2:
The patent applies the nested doll principle by placing a small preview window (containing the application interface) inside the first user interface. This nested structure allows the preview to be embedded within the existing interface framework, providing additional functionality without significantly increasing overall interface complexity.
3Ease of operation
If the application is launched only after user confirmation, then the user has control over the launch, but the perceived responsiveness is poor due to the wait time
Solution Approach 1:
The patent applies feedback by providing visual feedback in the form of a preview window that shows the application interface loading in real-time. This feedback mechanism maintains user control through the confirmation step while improving perceived responsiveness by showing that the application is actively loading and preparing, rather than showing a blank or static screen during the wait time.
Data Source
AI summary
A method for launching an application of a display device is provided. A first user interface comprising at least one icon for an application is displayed on a display screen of the display device. It is determined whether a hold duration of a focus on a target icon exceeds a preset time period, the target icon is an icon of a target application. In response to the hold duration exceeding the preset time period, the first user interface is updated by a second user interface comprising a display window superimposed on the first user interface, the display window presents a display interface of the target application. It is determined whether an activation instruction for the target icon is received. In response to the activation instruction, the second user interface is updated by a third user interface that is a display interface displaying the target application in a full-screen mode.
