Means for Solving the Problems

[0004] The technical solution of the present invention is as follows. A rotation interaction method based on single-handed operation, including the following steps: S1, the rotational movement of the rotating frame triggers a sensor to generate a signal, which detects the rotational speed and direction of the rotating frame and converts it into an electrical signal; S2, the processor, receives sensor signals and calculates and determines the rotation angle, speed, and direction of the rotating frame based on the changes in the signals; In S3, the processor associates rotation angle, velocity, and direction with specific device operations based on a pre-configured operation mapping table, and then executes the scheduled device operation.

[0005] In a more preferred embodiment, there is no mechanical contact between the rotating frame, the sensor, and the processor. In a more preferred embodiment, the rotation angle of the rotating frame is divided into multiple segments, with each segment corresponding to a different operation command. In another preferred embodiment, the sensor is a Hall sensor chip, which generates a signal as the rotating frame rotates, and the Hall sensor chip is positioned near the rotating frame to detect changes in the magnetic field and convert them into an electrical signal. Additionally, the rotating frame is equipped with at least one magnet, which works in conjunction with the Hall sensor chip to detect rotational motion.

[0006] Furthermore, the processor receives electrical signals and calculates the rotation angle of the rotating frame based on the changes in the signals; the processor determines the direction of rotation of the rotating frame by analyzing the phase changes of the electrical signals; the processor distinguishes whether the rotating frame is rotating normally or rapidly by analyzing the time intervals between changes in the electrical signals; if the time intervals between changes in the electrical signals are within a predetermined period, it is determined to be normal rotation and the corresponding device operation is initiated; if the time intervals between changes in the electrical signals are shorter than the predetermined period, it is determined to be rapid rotation and the corresponding device operation is initiated.

[0007] In a more preferred embodiment, a separate button or pressure-sensitive area that receives user commands is also included, and triggering this separate button or pressure-sensitive area enables single-click and double-click actions.

[0011] To more clearly explain the structural features and effects of the present invention, they will be described in detail using the following drawings and specific examples. The present invention relates to a rotational interaction method and smart device based on single-hand operation, as shown in Figures 1 to 5, and this interaction method includes the following steps: S1: The rotation of the rotating frame triggers a sensor to generate a signal, which detects the rotational speed and direction of the rotating frame and converts it into an electrical signal. In this embodiment, at least one magnet is installed on the rotating frame, and the sensor is located inside the device and near the magnet. The rotation of the rotating frame causes the magnet to move near the Hall sensor chip, causing a change in the magnetic field, which the Hall sensor chip generates a magnetic induction signal, detects the change in the magnetic field and converts it into an electrical signal.

[0012] S2: The processor receives the sensor signal and calculates and determines the rotation angle, velocity, and direction of the rotating frame based on the changes in the signal. In this embodiment, an ARM Cortex-M series microcontroller is used as the processor to receive the signal from the Hall sensor chip and determine the rotation angle, velocity, and direction of the rotating frame using digital signal processing techniques (e.g., filtering and integral calculations).

[0013] S3: The processor associates rotation angle, speed, and direction with specific device operations based on a scheduled operation mapping table, and then executes the scheduled device operation. Inside the processor is a memory module, and the operation mapping table stored in the memory module associates the calculation results with the device operations. For example, an increase in rotation angle corresponds to scrolling down the page, and a decrease in rotation angle corresponds to scrolling up. In this embodiment, the rotation angle of the rotating frame is divided into multiple segments, each segment corresponding to a different operation command. The rotating frame is designed in the form of a rotatable dial divided into 360 degrees. There is no mechanical contact between the rotating frame, the Hall sensor chip, and the processor, employing a non-contact detection method, which reduces mechanical wear and improves the durability of the device.

[0014] The processor receives electrical signals and calculates the rotation angle of the rotating frame based on the changes in the signals. The processor determines the direction of rotation of the rotating frame by analyzing the phase changes of the electrical signals and distinguishes between normal rotation and rapid rotation by analyzing the time intervals between changes in the electrical signals. Specifically, if the time intervals between changes in the electrical signals are within a predetermined period, it is determined to be normal rotation and the corresponding device operation is initiated. If the time intervals between changes in the electrical signals are shorter than the predetermined period, it is determined to be rapid rotation and the corresponding device operation is initiated.

[0015] Furthermore, it includes a separate button or pressure-sensing area for receiving user commands, and single-click and double-click operations on the device interface are achieved by triggering this separate button or pressure-sensing area. In this embodiment, the pressure-sensing area is mounted on a rotating frame, and a pressure sensor that senses pressure resistance is installed inside the rotating frame. The separate button is mounted on the side of the rotating frame.

[0016] A smart device utilizing the above interaction method for single-handed operation includes a case 10, a rotating frame 20, independent buttons 30, sensors, a processor, and a screen 40, where the rotating frame 20, sensors, and processor are located inside the case 10, and the screen 40 is exposed on the outside of the device. The rotating frame 20 is located on the outside of the smart device and is positioned to surround the outside of the screen 40, allowing the user to operate it. The independent buttons 30 are located on the side of the rotating frame 20. Sensors are located in a fixed position inside the device and detect changes in the magnetic field generated by magnets.

[0017] The user can operate the device by rotating the rotating frame 20. At least one magnet is installed on the circumference of the rotating frame 20, and a pressure sensor is installed inside the rotating frame 20. The sensor is a Hall sensor chip, installed near the rotating frame, and detects changes in the magnetic field. The processor has a memory module, has memory and computing capabilities, calculates the rotation angle, speed, and direction of the rotating frame based on the sensor signal, and executes the corresponding device operation.

[0018] This smart device is mainly operated by rotating the rotating frame. Using Hall magnetic sensing technology, the dial of the rotating frame is divided into 360 degrees, and the position of the magnet continues to change as the dial rotates. The magnet and the Hall sensor chip generate a magnetic induction signal, and the Hall effect sensor chip detects changes in the magnetic field and estimates the current angular position of the dial based on the changes. Also, the Hall effect sensor detects changes in the strength and direction of the magnetic field in real time, and determines the rotation direction and speed by calculating the time interval or frequency of the changes in the magnetic field. Combine the different signals generated by the forward and reverse rotation of the dial with a series of interaction methods generated by the only independent button (or the rotating frame that senses pressure). The Hall effect sensor chip transmits the detected rotation information to the processor of the device, and the processor determines the user's rotation operation based on the data provided by the sensor and makes the corresponding response on the interface. For example, menu scrolling, interface zooming, etc.

[0019] The specific operation method of this smart device is as follows: When the rotating frame is quickly rotated 180 degrees, the operation of advancing to the next page / skipping / returning to the previous page will be executed after 0.5 seconds. When the operation is triggered, a position indicator will be displayed on the screen, and the operation will be canceled if it is rotated more than 10 degrees in the reverse direction.

[0020] 2. The rotating frame has a built-in pressure-sensitive resistor, which has vibration feedback and can detect compression. A separate button is located on the side of the rotating frame. The pressure-sensitive resistor and the separate button are independent in the two operating modes and have the same operational effect. In other words, the action of compressing the rotating frame and the action of pressing the separate button achieve the same function. The rotating frame has a built-in pressure-sensitive resistor that can detect compression. A separate button is located on the side of the rotating frame. On the main screen, rotating the rotating frame 90 degrees will take you to the APP screen. You can select the APP by rotating it normally, or enter the APP by compressing the rotating frame or pressing the separate button. After entering the APP, pressing and holding the separate button or compressing the rotating frame will return you to the home key, and double-clicking the button or compressing the rotating frame twice will return you to cancel.

[0021] 3. On the standby screen, rotating the rotating frame 180 degrees or more in the opposite direction will activate the audio function and a prompt will appear in the UI. Rotating it another 90 degrees will open it, and rotating it in the opposite direction or stopping the rotation will cancel it. 4. On the PowerPoint screen, turning pages with normal rotation and quickly rotating the rotation frame a full turn will automatically play the PowerPoint presentation (during dual-display projection and dual-display DisplayPort).

[0022] 5. When the screen is in standby mode, if you quickly rotate the rotating frame 90 degrees counterclockwise and then return it to its original position, the camera icon will appear. If you rotate it counterclockwise again more quickly, the camera will open. This operation helps prevent accidental operation during rapid rotation. 6. On UI screens such as translation interfaces, lightly rotating the rotation frame will switch between screens A and B.

[0023] 7. On the music screen, rotating the frame normally adjusts the volume, rotating it quickly fast-forwards / rewinds, and rotating the frame more than 360 degrees quickly switches to the next / previous song. 8. The independent button enables the following three operations with a single hand: a. Short press to enter; b. Long press for 2 seconds to return to the home screen; c. Short press twice to enter the F screen.

[0024] Design focus of the present invention The proposed rotational interaction method and smart device are based on Hall magnetic induction technology and have the following advantages: ● Firstly, it improves the accuracy and sensitivity of rotational operations, allowing for real-time detection of rotation angle, direction, and speed. ● Secondly, by adopting a non-contact trigger signal method, mechanical wear is reduced and the durability of the device is improved. ● Thirdly, users can access a variety of interaction functions on smart devices with simple rotational operations, improving the ease of use and user experience of the device.

[0025] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the invention in any way. Therefore, any minor changes, equivalent changes, and modifications made to the above embodiments based on the technical essence of the invention shall fall within the scope of the technical solution of the present invention.
