Problems solved by technology
[0002] At present, in the process of processing gesture data, gesture actions in any state are analyzed in real time. As long as the detected gesture data meets the preset trigger conditions, the specified gesture action associated with the gesture data can be triggered. However, This gesture recognition method has no effective means to distinguish valid gesture data from invalid gesture data. For irregular regular gestures triggered by the user, with this method, the wearable device cannot correctly judge the irregular regular gestures. Whether the action is valid gesture data, thus increasing the probability of misrecognition caused by irregular regular gesture actions accidentally triggering specified gesture actions

Embodiment Construction
[0064] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0065] Based on the above problems, the present invention provides a gesture recognition method.
[0066] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the gesture recognition method of the present invention.
[0067] In this embodiment, the gesture recognition method includes:
[0068] Step S10, when the mobile terminal detects the gesture signal, obtain the original acceleration parameter currently detected by the acceleration sensor in the mobile terminal, and obtain the historical acceleration parameter within the preset time period before the current moment;
[0069] In this embodiment, the mobile terminal can be understood as a wearable device, such as a smart bracelet, and the gesture recognition method of this solution is suitable for wearable devices with high real-tim...

The invention discloses a gesture recognition method and device. The method comprises the following steps: when detecting a gesture signal by a mobile terminal, acquiring an original acceleration parameter which is currently detected by an acceleration sensor in the mobile terminal, and acquiring a historical acceleration parameter with a preset time period before the current moment; calculating a state signal logical vector of the current moment according to the original acceleration parameter and the historical acceleration parameter, and acquiring a first gesture state within the preset time period before the current moment; and determining first gesture state integration time of the current moment according to the state signal logical vector and the first gesture state, and determining a second gesture state of the current moment according to the first gesture state integration time. The gesture recognition method provided by the invention reduces the probability of incorrectly triggering specified gestures by irregular conventional gestures and improves the accuracy of gesture recognition.
Description
technical field [0001] The present invention relates to the field of human-computer interaction technology, in particular to a gesture recognition method and device. Background technique [0002] At present, in the process of processing gesture data, gesture actions in any state are analyzed in real time. As long as the detected gesture data meets the preset trigger conditions, the specified gesture action associated with the gesture data can be triggered. However, This gesture recognition method has no effective means to distinguish valid gesture data from invalid gesture data. For irregular regular gestures triggered by the user, with this method, the wearable device cannot correctly judge the irregular regular gestures. Whether the action is valid gesture data, thereby increasing the probability of misrecognition caused by an irregular regular gesture action accidentally triggering a specified gesture action.
