[0002] A ring mouse, also known as an air mouse, is a mouse that is shaped like a ring and is worn on the finger. The ring mouse is equipped with sensors such as a gyroscope and an accelerometer.

[0036] The present invention provides a method and system for recognizing gestures through a ring mouse. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] Regarding the technical principles of the present invention, it needs to be explained in advance that the present invention obtains the spatial motion data of the ring mouse through the sensor in the ring mouse. The sensor includes a three-axis gyroscope and a three-axis accelerometer. Since some gestures will produce specific spatial motion trajectories, such as moving the palm backward to make a fist and reversing the palm, the spatial motion data corresponding to the gesture can be obtained through the sensor when the ring mouse follows the hand. Conversely, the corresponding gesture can also be identified based on the spatial motion data of the ring mouse.

[0038] See also Figure 1 , Figure 1 is a flow chart of a method for recognizing gestures through a ring mouse according to the present invention; Figure 1 As shown, a method for recognizing gestures by using a ring mouse of the present invention comprises:

[0039] Step 100, pre-setting gesture data, the gesture data including motion data of multiple gestures, the motion data including linear motion data and rotational motion data; specifically, the present invention can recognize many gestures, each recognizable gesture has standard linear motion data and rotational motion data, these gesture data are stored in a database, and the gestures corresponding to the gesture data include one or more of moving the palm up, moving the palm down, clicking the finger downward, turning the palm over, drawing a circle clockwise, drawing a circle counterclockwise, moving the palm backward to make a fist, moving the palm forward to spread out, and drawing letters.

[0040] Step 200, when the ring mouse moves with the hand, the spatial motion data of the ring mouse is obtained in real time; specifically, the ring mouse is worn on the index finger of the user's right hand, and when the ring mouse moves with the hand, the ring mouse sensor obtains the spatial motion data of the ring mouse in real time, the sensor is a three-axis gyroscope and a three-axis accelerometer, and the obtained spatial motion data is divided into ring mouse linear motion data and ring mouse rotational motion data, the ring mouse linear motion data describes the motion curve of the ring mouse, and the ring mouse rotational motion data describes the angle change of the ring mouse.

[0041] Step 300, compare the spatial motion data with the gesture data; specifically, after the ring mouse obtains the spatial motion data, compare the linear motion data of the ring mouse with the preset linear motion data, and compare the rotational motion data of the ring mouse with the preset rotational motion data. It should be noted that when comparing the spatial motion data with the gesture data, the spatial motion data must completely match the gesture data, that is, the comparison is successful only when the spatial motion data matches the motion data of a certain gesture.

[0042] Step 400: When the spatial motion data meets the motion data of a certain gesture, the gesture is determined to be a ring mouse following hand gesture. Specifically, the motion data includes linear motion data and rotational motion data. The preset linear motion data and rotational motion data have directionality and are a range value. For example, the linear motion data corresponding to the palm moving backward and making a fist is (-, >10cm) and the rotational motion data is (↓, >70°), - represents backward movement, ↓ represents downward rotation; when the spatial motion data meets the linear motion data of moving backward more than 10cm and the rotational motion data of rotating downward more than 70°, the ring mouse following hand gesture is determined to be a palm moving backward and making a fist.

[0043] A method for identifying gestures through a ring mouse as described above, wherein the gestures corresponding to the gesture data include one or more of palm up, palm down, finger down click, palm flip, clockwise circle, counterclockwise circle, palm back to make a fist, palm forward to spread out, and letter drawing. Specifically, the above gestures are all recognizable, and each gesture corresponds to separate linear motion data and rotational motion data, such as the linear motion data of palm up is (+, >10cm), and the rotational motion data is (N, <5°), where the rotational motion data is actually an error range, because the palm up will produce an angle change, N means that the direction is not determined, and <5° means that the rotational motion data does not exceed 5°; it should be particularly noted that the difference between palm down and finger down click is that the palm down has a smaller rotational motion data, and the rotational motion data is controlled within the error range, and the finger down click has a larger angle rotational motion data. The linear motion data and rotational motion data of other gestures are specific and will not be repeated here.

[0044] A method for identifying gestures through a ring mouse as described above, wherein the spatial motion data of the ring mouse includes linear motion data of the ring mouse and rotational motion data of the ring mouse. Specifically, the linear motion data of the ring mouse is obtained through a three-axis accelerometer, and the rotational motion data of the ring mouse is obtained through a three-axis gyroscope. The linear motion data of the ring mouse is compared with the linear motion data of the gesture data, and the rotational motion data of the ring mouse is compared with the rotational motion data of the gesture data.

[0045] In the method for recognizing gestures through a ring mouse as described above, step 100 specifically includes: the first step of obtaining linear motion data of the ring mouse through a three-axis accelerometer; the second step of obtaining rotational motion data of the ring mouse through a three-axis gyroscope. Specifically, the combination of a three-axis accelerometer and a three-axis gyroscope can accurately obtain spatial motion data of the ring mouse, and the three-axis accelerometer and the three-axis gyroscope are both prior art and will not be described in detail; obtaining linear motion data of the ring mouse through a three-axis accelerometer and obtaining rotational motion data of the ring mouse through a three-axis gyroscope are also prior art and will not be described in detail.

It is completely different from the existing data gloves.
