Wearable Display Preview Layout for Low-CPU App Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices like smartwatches experience freezing during picture switching due to high CPU usage for image drawing and rendering, leading to poor operation smoothness and user experience.
Innovation Solution
Implement a display method with two display areas: a first area for application icons and a second area for interface preview, where the application interface is displayed starting from the edge of the second area, reducing CPU load and improving smoothness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the application interface is displayed starting from the application icon position, then the interface can be launched from the desktop, but the CPU consumes large computing power for image drawing and rendering causing freezing
Solution Approach 1:
The patent pre-displays the application interface in the second display area before the user activates the application. This preliminary rendering allows the interface to be ready for immediate display, reducing the CPU load during actual launch and preventing freezing while maintaining smooth operation.
Solution Approach 2:
The patent divides the display into two separate areas: a first display area for application icons and a second display area for pre-rendered application interfaces. This segmentation allows the system to pre-process and display interfaces in one area while maintaining the desktop interface in another area, reducing overall CPU consumption during launch.
2Ease of operation
If the application interface entirely covers the screen from the icon position, then the interface launch is straightforward, but the picture switching smoothness deteriorates due to large stroke length
Solution Approach 1:
The application interface is pre-displayed in the second display area before launch, so when the user activates the application, the interface is already rendered and can be switched to immediately. This eliminates the need for large-stroke rendering from the icon position, significantly improving picture switching smoothness.
Solution Approach 2:
The patent introduces a second display area that operates independently from the traditional single-screen icon-to-interface transition. By utilizing this additional dimensional space for pre-rendering, the system achieves faster interface switching without increasing the stroke length in the traditional sense.
3Power
If the application interface is pre-displayed in the second display area, then the CPU load during launch is reduced, but the display layout becomes more complex
Solution Approach 1:
The display is segmented into two functional areas with distinct purposes: the first display area for desktop icons and the second display area for pre-rendered interfaces. This segmentation, while increasing layout complexity, significantly reduces CPU load during application launch by enabling parallel processing of interface rendering.
Solution Approach 2:
The patent implements dynamic switching between the two display areas based on user interaction. The second display area is activated only when needed for interface pre-display, allowing the system to adapt the display layout dynamically rather than using a static complex layout always, thus managing complexity through temporal separation.
