Smartwatch Crown Function Switching for Faster App Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices like smartwatches require complex and time-consuming interactive operations for users to access desired functions, reducing human-machine interaction and delaying the initiation of needed applications.
Innovation Solution
An electronic device equipped with a first component, such as a watch crown, allows users to initiate operations that trigger the display of function-specific controls, enabling direct access to functions like timing, motion, or gaming through rotation-based interactions, reducing unnecessary steps and improving user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users search for applications in the smartwatch to access desired functions, then the device can provide comprehensive function access, but the interactive operations become complex and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple quick access controls on the watch face that directly correspond to frequently used functions. When the user rotates the crown, the system preemptively displays relevant controls without requiring application search or navigation, thus resolving the contradiction between comprehensive function access and quick access by preparing function entry points in advance.
2Speed
If the smartwatch loads all application programs into memory, then function access is faster, but memory resources and energy consumption increase
Solution Approach 1:
The system performs preliminary action by pre-loading only the essential control interfaces and core function programs into memory based on predicted user needs, rather than loading entire applications. When a user rotates the crown, the system quickly activates the corresponding pre-loaded control, achieving fast function access while minimizing memory usage and energy consumption by loading only necessary components in advance.
3Ease of operation
If the smartwatch provides direct function access through crown rotation, then user experience is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing the crown component to serve multiple functions: it acts as both a traditional navigation control and a trigger for quick function access. The same crown rotation gesture can access different functions based on the current context (watch face type, time of day, user preferences), reducing the need for separate control mechanisms and minimizing device complexity while enhancing user experience.

AI summary
A function switching method and apparatus, and an electronic device, related to the field of electronic device technologies. The method includes: the electronic device first displays a first interface, where the first interface is a display interface of a first application. Then, the electronic device displays, in the first interface in response to a first operation when detecting that a user initiates the first operation on a first component, a first control that may be used to implement a first function. Further, the electronic device may perform the first function in response to an operation initiated by the user on the first control. The first component may be, for example, a watch crown, and the first operation may be a clockwise rotation operation.
