Declarative UI Timeline Views for Low-Latency Mobile Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for displaying application information on mobile devices are inefficient, as they often require users to launch applications, leading to increased interaction time and device processing time.
Innovation Solution
The implementation of user interface timeline views that are declaratively defined and rendered in advance by a background process, allowing for efficient display of dynamic application content without the need to launch associated applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If application information is displayed by launching the associated application, then the information can be accessed, but user interaction time and device processing time increase
Solution Approach 1:
The system pre-renders user interface timeline views in advance and stores them for later display. When a user wants to access application information, the pre-rendered views are immediately displayed without requiring the full application to be launched, thus reducing user interaction time while maintaining ease of access
Solution Approach 2:
The system creates simplified copies of application interfaces (timeline views) that contain essential information and can be displayed independently. These copies are rendered in advance and stored, allowing users to access application information through lightweight view displays rather than launching the complete application
2Loss of time
If application information is displayed by launching the associated application, then the information can be accessed, but device processing time increases
Solution Approach 1:
The system performs the computationally intensive rendering of user interface views in advance during low-load periods and stores the rendered views. When display is needed, the system simply retrieves and displays the pre-rendered views, dramatically reducing device processing time at the moment of user access while maintaining full functionality
Solution Approach 2:
The system creates and stores copy representations of application interfaces that can be displayed without requiring the original application's full processing resources. These copied views contain sufficient information for user interaction but require minimal processing to display
3Use of energy by moving object
If user interface timeline views are rendered in advance, then resource usage is optimized and battery consumption is reduced, but rendering cost must be managed within update budget
Solution Approach 1:
The system renders user interface timeline views in advance during periods of low device activity and stores them for later display. This shifts the energy-intensive rendering operations to times when the device is already active and resources are available, reducing peak power consumption and extending battery life while managing rendering costs through scheduled updates
Solution Approach 2:
The system implements periodic rendering of timeline views according to update budgets and device activity patterns. By scheduling rendering operations periodically rather than continuously or on-demand, the system optimizes energy usage and manages rendering costs effectively while ensuring views are available when needed
Data Source
AI summary
A device implementing a system to render user interface timeline views for display of dynamic application content includes a processor configured to retrieve a data structure corresponding to user interfaces of an application associated with respective times, and at least one declaratively defined user interface element. The processor is further configured to determine whether a rendering cost of a plurality of the user interfaces complies with an update budget of the application, where the rendering cost includes interpreting the at least one declaratively defined user interface element for the respective times. When the rendering cost is determined to comply, the processor is further configured to render the plurality of the user interfaces in advance of the respective times associated with the plurality of the user interfaces. The processor is further configured to display at least one of the rendered plurality of the user interfaces based on a current time.
