Smartwatch Crown Interaction for Small-Screen Watch Faces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interacting with a smartwatch through its small screen is cumbersome, and current methods of using the watch crown for interaction are monotonous, failing to meet user's personalized needs and underutilizing its potential functions.
Innovation Solution
The smartwatch displays interactive objects on the watch face interface, and based on the direction of crown rotation, controls these objects to move, shift, swing, or adjust their appearance, enhancing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the smartwatch uses only the small screen for interaction, then the device structure remains simple, but the user experience becomes cumbersome
Solution Approach 1:
The crown component is transformed from a single-function interface switch to a multi-functional interaction controller. It can detect rotation directions (clockwise/counterclockwise), rotation speeds, and continuous rotation patterns, enabling diverse interaction modes including character selection, menu navigation, and parameter adjustment, thereby improving ease of operation without requiring a larger screen
2Adaptability or versatility
If the crown is used only for switching interfaces and adjusting parameters, then the interaction method remains simple, but the crown's potential functions are underutilized
Solution Approach 1:
The crown interaction system transitions from static, predefined functions to dynamic, context-aware interactions. The system adapts the crown's functionality based on the current interface state, rotation characteristics (speed, direction, continuity), and application context, enabling the same physical component to perform multiple different functions without increasing device complexity
Solution Approach 2:
The patent utilizes changes in rotation parameters (direction, speed, duration) to trigger different interaction outcomes. For example, fast rotation vs. slow rotation, clockwise vs. counterclockwise, and continuous vs. intermittent rotation all map to different functions, maximizing crown versatility through parameter variation rather than adding physical components
3Adaptability or versatility
If the crown interaction is limited to basic functions, then the system remains simple to implement, but it fails to meet user's personalized needs
Solution Approach 1:
The system implements feedback mechanisms where the crown's rotation characteristics are continuously monitored and fed back to adjust the interaction mode. The system learns from user behavior patterns and adapts the interaction experience accordingly, enabling personalized interaction without requiring complex artificial intelligence algorithms

AI summary
This application relates to an interaction method and a smartwatch. An example method includes: displaying a watch face interface, where the watch face interface comprises clock hands and a first pattern; and in response to an operation of rotating a crown by a user, canceling display of the clock hands and adjusting a size of the first pattern based on a rotation direction.
