Recently, Samsung disclosed a patent regarding the interactive design of smartwatches, focusing on optimizing the user interface of wearable devices. By integrating a touch-sensitive area on the strap with an intelligent rotating interface, it aims to provide users with a more dynamic interaction experience.
Traditional smartwatches primarily rely on screen touch for interaction, while Samsung’s innovative patent introduces a touch-sensitive area on the strap, which may even include a miniature display.
The patent describes that users can perform multi-touch gestures on the strap area and trigger different interaction functions by moving their fingers. For example, sliding the strap may switch applications, pinching fingers could adjust the volume, and it may even support more complex gesture combinations.


Another design highlight is the automatic interface adjustment feature. The patent indicates that the watch can detect the orientation or tilt angle of the wrist and dynamically adjust the GUI layout accordingly. For example:
When the user’s wrist is naturally hanging down, the interface elements may automatically rotate to ensure text and icons remain readable. When the user raises their wrist to view notifications, the interface may optimize the display to prioritize important information.


This adaptive design allows the watch interface to no longer be static but to intelligently adjust based on the user’s actual usage scenario, enhancing the comfort of reading and operation.
The patent also hints at the application of gesture recognition technology. Icons in the diagrams show arrows and annotations, indicating that the device may support finger movements or wrist motion recognition. For instance, swiping the wrist may switch applications; clenching a fist or rotating the wrist may trigger specific functions (such as taking a photo or playing music).
This interaction method is similar to the Apple Watch’s “Digital Crown” or Huawei’s wrist press feature, but Samsung’s solution combines touch and motion recognition, providing a rich array of control options.
Currently, the smartwatch market is highly competitive, dominated by leading brands. From Samsung’s patent, it is evident that future smartwatches will explore more novel interaction methods, such as the combination of touch-sensitive areas on the strap with intelligent rotating interfaces, enabling multi-touch, gesture recognition, and other complex operations to enhance the dynamism and convenience of interactions. They will also evolve towards a more natural and convenient direction, making operations more ergonomic and reducing the learning curve for users.
