Notification Cache Interfaces for Lower-Power Touch Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User interfaces for accessing notifications on electronic devices with touch-sensitive surfaces are cumbersome and inefficient, leading to energy waste, particularly in battery-operated devices.
Innovation Solution
Implement improved methods and interfaces for accessing notifications, including transitioning between screen states, navigating notification history, and using cover sheets and mini-application objects, which reduce the number and nature of user inputs, conserve power, and enhance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional notification interfaces are used, then notifications can be displayed, but user interaction becomes cumbersome and energy consumption increases
Solution Approach 1:
The system pre-loads and stages notification content in the notification cache before it is actually displayed to the user. This allows notifications to be ready for immediate display without requiring full rendering or data processing at the moment of user interaction, thereby reducing energy consumption while maintaining ease of access.
Solution Approach 2:
The notification cache acts as an intermediary layer between the notification source and the display interface. It stores and manages notification data, allowing the system to serve notifications efficiently without direct real-time processing during user interaction, thus reducing energy consumption while maintaining operational ease.
2Loss of information
If notifications are displayed immediately upon receipt, then information is available to users, but navigation becomes confusing and time-consuming
Solution Approach 1:
Notifications are pre-processed and staged in the notification cache with their final display configuration prepared in advance. This eliminates the need for complex real-time navigation or reconfiguration when users access notifications, reducing navigation time while ensuring information is immediately available upon display.
3Ease of operation
If the device transitions to screen-on state for every notification access, then full interface functionality is available, but power consumption increases
Solution Approach 1:
The system implements partial screen-on functionality by displaying notifications in a cached, pre-rendered state that provides essential notification access without requiring the device to fully transition to the complete screen-on state. This delivers sufficient functionality for notification viewing while significantly reducing power consumption compared to full screen activation.
Data Source
AI summary
An electronic device concurrently displays a first user interface of first software and status information for an application that is different from the first software. The status information includes content of the application. As a state of the application changes, the device updates the content of the application displayed in the status information. In response to detecting an input corresponding to a request to display a different, second user interface of different, second software, while concurrently displaying the first user interface and a respective user interface object that includes the status information, the device ceases to display the first user interface and the respective user interface object, and displays the second user interface including content of the application, including, as the state of the application changes, updating the content of the application displayed in the second user interface, which includes information that is different from the status information.
