DETAILED DESCRIPTION

[0013] Example 1

[0014] like Figures 1 to 4 As shown, the utility model is a finger ring mouse, the main body of which is composed of a finger ring outer ring 1 and a finger ring inner ring 2. The finger ring outer ring 1 can be made of metal, plastic, ceramic and other materials according to the design, and the finger ring inner ring 2 is made of resin. The finger ring inner ring 2 is fixedly connected to the inner side of the finger ring outer ring 1. A flexible circuit board 3 and a battery 4 are sealed and installed between the finger ring outer ring 1 and the finger ring inner ring 2. The flexible circuit board 3 is electrically connected with a wireless charging module 301, a sensor 302, a charging management module 303, a lithium battery voltage stabilization protection module 304, a Bluetooth BLE chip 305, an indicator light 306, and a control switch 307. The sensor 302 is a three-axis three-in-one sensor including an acceleration sensor, a geomagnetic sensor and a gyroscope, which is used to detect three-dimensional motion and direction. The battery 4 is a polymer lithium battery, which supports wireless charging and contact-type wired charging. The charging method can be selected according to design requirements.

[0015] The battery 4 is electrically connected to the wireless charging module 301 through the charging management module 303, and is connected to an external power source through the wireless charging module 301. The input voltage is processed by the charging management module 303 and then the input current is used to charge the battery 4. The lithium battery voltage stabilization protection module 304 prevents voltage over-discharge, short circuit, etc., and protects the circuit. The battery 4 is electrically connected to the sensor 302 through the lithium battery voltage stabilization protection module 304. The Bluetooth BLE chip 305 is electrically connected to the sensor 302, the charging management module 303, the indicator light 306, the control switch 307 and the battery 4 respectively. The indicator light 306 displays the system status. The Bluetooth BLE chip 305 is connected to the terminal device 308 such as a computer and a tablet computer to ensure low power consumption and stable connection. The finger and hand movements detected by the sensor 302 are converted into action instructions such as cursor movement, clicking, and scrolling through the system algorithm.

[0016] The ring mouse is worn on the user's finger, obtains hand movement information through the sensor 302, and performs data analysis through the Bluetooth BLE chip 305, converts the movement information data into action commands such as cursor movement, clicking, scrolling, etc. and transmits them to terminal devices 308 such as computers and tablets to realize input control of the terminal device 308.

[0017] Gesture command settings include: left click: lightly click downward with your index finger;

[0018] Right click: thumb click index finger;

[0019] Double-click the left button: Click the index finger downward twice quickly;

[0020] Roll: Slide your thumb up and down your index finger;

[0021] Drag: Press the target with your index finger and move it;

[0022] Zoom in / out: open and close your thumb and index finger in the air;

[0023] Forward / backward: slide your index finger left or right;

[0024] Through these gesture operations, common mouse functions can be realized and the user experience can be improved.

[0025] Bluetooth BLE chip preprocesses data:

[0026] Fourier transform and power spectrum calculation: In the data preprocessing stage, Fourier transform is performed on each motion sensor data frame to calculate the power spectrum data of the motion sensor. The specific steps are as follows:

[0027] 1. Fast Fourier Transform (FFT):

[0028] -Perform an FFT on each frame of motion sensor data (such as accelerometer and gyroscope data).

[0029] -Generate power spectrum data for each sensor axis, such as the power spectrum Xt, Yt and Zt of the x, y, z axes of the accelerometer, and the power spectrum Rt, Pt and Wt of the roll, pitch and yaw axes of the gyroscope.

[0030] 2. Data combination and maximum value calculation:

[0031] -For each accelerometer data frame, take the maximum value of the x, y, and z axes to generate a single accelerometer frame value At, for example, At,i=max(Xt,i,Yt,i,Zt,i).

[0032] - Similarly, for each gyroscope data frame, the maximum value of the roll, pitch and yaw axes is taken to generate a single gyroscope frame value Gt, for example, Gt,i = max(Rt,i, Pt,i, Wt,i).

[0033] 3. Data averaging:

[0034] - Averaging a predetermined number of past data frames (eg, 20 frames) to generate a plurality of average motion sensor data values, for example, average accelerometer value Acci=mean(At,i, At-1,i, ..., At-w+1,i).

[0035] - Similarly, generate the average gyroscope value Gcci=mean(Gt,i,Gt-1,i,...,Gt-w+1,i).

[0036] Feature extraction subsystem

[0037] Feature extraction algorithm: The feature extraction subsystem is used to generate feature data based on the preprocessed sensor data. The feature extraction algorithm can be applied to the sensor data to select useful features. The specific steps are as follows:

[0038] 1. Statistical feature extraction:

[0039] - extracting a plurality of statistical features from the plurality of average motion sensor data values ​​and proximity sensor data values.

[0040] -Statistical features include: mean, minimum, maximum, median, standard deviation, range, and number of peaks.

[0041] -Generate summary data from these statistical features, such as mean, minimum, maximum, median, standard deviation, range, and number of peaks for each channel.

[0042] 2. Feature Fusion:

[0043] - Aggregate all statistical features of all channels into a one-dimensional vector D.

[0044] - Use the vector D as the input of the classifier for subsequent gesture recognition.

[0045] Gesture Recognition Algorithm

[0046] Classifier and gesture recognition: The classifier is used to classify gestures based on feature vectors. The specific steps are as follows:

[0047] 1. Classifier Model:

[0048] - The classifier can be any type of algorithm or model, such as a Support Vector Machine (SVM) or a Convolutional Neural Network (CNN).

[0049] - Training the classifier requires collecting labeled training data from sensors. The same fingers are used for training and gesture recognition to improve the effectiveness of training.

[0050] 2. Gesture classification:

[0051] - Classify gestures using a classifier to classify multi-finger air gestures into specific gesture categories.

[0052] -The classifier outputs gesture classification data, including labels or probability data associating sensor data with gesture categories.

[0053] 3. Dynamic Time Warping (DTW) algorithm:

[0054] - In some embodiments, the DTW algorithm is used to compare the filtered data information with the gesture model to find the typical model with the smallest Euclidean distance.

[0055] -Based on DTW results and statistical features, combined with the graphic features of each gesture, gesture information is determined to complete gesture input.

[0056] Cooperation between applications
