Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In order to detect a knocking event without an acceleration sensor, an embodiment of the application provides a knocking event detection method and a device, wherein the knocking event detection method comprises the following steps:
when sound information belonging to a knocking event is monitored and a clicking event is detected, judging whether the time difference between the moment of monitoring the sound information and the moment of detecting the clicking event is smaller than a first preset time;
if so, a tapping event is determined to have occurred.
According to the technical scheme provided by the embodiment of the application, the knocking event can be considered to be the combination of the clicking event and the sound, so that the knocking event can be judged to occur under the conditions that the sound information belonging to the knocking event is monitored, the clicking event is detected, and the time difference between the time of monitoring the sound information and the time of detecting the clicking event is smaller than the first preset time. The scheme can completely eliminate the use of an acceleration sensor, and further realize the detection of the knocking event under the condition without the acceleration sensor.
First, a method for detecting a knocking event according to an embodiment of the present application will be described below. The method for detecting the knocking event can be applied to equipment with a touch screen function, such as a touch screen mobile phone, a tablet, a conference tablet and an all-in-one machine capable of touching a screen.
As shown in fig. 1, a method for detecting a tapping event provided by an embodiment of the present application includes the following steps.
S101, when sound information belonging to a knocking event is monitored and a clicking event is detected, judging whether the time difference between the moment of monitoring the sound information and the moment of detecting the clicking event is smaller than a first preset time; if so, step S102 is performed.
The click event may be a click operation performed by a user on the touch screen, and the click event may be considered as a combination of the click event and sound, that is, when the user clicks the touch screen harder, sound may be generated on the touch screen, and at this time, the click event may be considered as a click. For example, when a user strongly clicks the touch screen with a finger joint, a sound is generated on the touch screen, and this motion of the finger joint may be considered as a tapping motion.
The sound information can be monitored in real time, in one implementation mode, the sound information can be collected in real time, whether the collected sound information is the sound information of the knocking event or not is detected, and if the collected sound information is the sound information of the knocking event, the sound information belonging to the knocking event can be determined to be monitored. The mode of collecting the sound information can adopt a sound pick-up, a matrix type microphone and the like.
The first preset time length may be set by a user, and the first preset time length may be set to be shorter in order to ensure that the monitored sound information and the detected click event belong to the same click event. For example, the first preset time period may be set to 50 ms, and when a difference time period between a time when the sound information is monitored and a time when the click event is detected is less than 50 ms, it may be determined that the click event occurs.
S102, judging that the knocking event occurs.
When the time difference between the time when the sound information is monitored and the time when the click event is detected is less than a first preset time, the monitored sound information and the detected click event can be considered to belong to the same click event, and at this time, the occurrence of the click event can be judged.
If the time difference between the time when the sound information is monitored and the time when the click event is detected is not less than the first preset time, the monitored sound information and the detected click event can be considered to belong to different click events respectively.
If only the sound information belonging to the tapping event is monitored and the tapping event is not detected, or only the tapping event is detected and the sound information belonging to the tapping event is not monitored, it can be determined that the tapping event does not occur.
After the occurrence of the knocking event is determined, the operation corresponding to the knocking event can be executed. The operation corresponding to the knocking event may be preset. For example, if the operation corresponding to the preset tapping event is a screen capturing operation, the screen capturing operation is executed after the tapping event is determined to occur.
In one embodiment, the operation corresponding to the tapping event may be set in a user-defined manner, for example, the operation corresponding to the tapping event may be set as a screen capture operation, and may also be set as a wake-up operation.
In one embodiment, the click can be divided into a press action and a lift action, when a click event occurs, the press action occurs first, after the touch object contacts the touch screen, the lift action occurs, and after the lift action is completed, a click action is completed. The touch object may be a finger tip, a finger joint, a stylus, or the like.
When the touch object performs gesture operation on the touch screen, the device of the touch screen can acquire touch information. The type of the acquired touch information may include at least one of a press-down information, a lift-up information, a slide information, and the like. The touch screen comprises a touch screen body, a touch screen and a touch screen, wherein the touch screen body is provided with a touch screen body, the touch screen body is provided with a touch screen, the touch. After the pressing action occurs and before the lifting action occurs, the touch object is contacted with the touch screen.
When the touch information comprises first pressing information and first lifting information, the pressing action and the lifting action are represented, when the time interval for acquiring the first pressing information and the first lifting information is less than a second preset time length, the click event can be judged to occur, and the pressing action and the lifting action at one time with short time interval are the one-time click action. The second preset duration may be set by a user, and in general, the second preset duration may be set to be smaller in order to ensure that the pressing action and the lifting action belong to the same clicking action.
When the touch information includes second press-down information and second lift-up information, and a time interval between the obtaining of the second press-down information and the obtaining of the second lift-up information is not less than a second preset time length, it may be considered that the press-down action indicated by the second press-down information and the lift-up action indicated by the second lift-up information belong to a long press-down action, and it may be determined that a click event does not occur at this time.
For example, if the time interval between the pressing action indicated by the second pressing information and the lifting action indicated by the second lifting information is 2 seconds and is greater than the second preset time length by 50 milliseconds, it may be determined that the long pressing action occurs and the click event does not occur.
When the touch information includes third press-down information, sliding information, and third lift-up information, it indicates that a press-down action, a sliding action, and a lift-up action have occurred, and at this time, it may be considered that the touch object performs a sliding gesture or a dragging gesture including a sliding action on the touch screen, and it may be determined that a click event has not occurred.
In one embodiment, when the touch information includes third press-down information, sliding information, and third lift-up information, a sliding distance after the press-down action occurs may be determined from the sliding information, and it may be determined whether the sliding distance is smaller than a preset distance. The sliding distance is a distance that the touch object slides on the touch screen in a contact process between the touch object and the touch screen after the pressing action occurs and before the lifting action occurs.
Taking fig. 2 as an example, when the finger performs a pressing action, the finger is located at a position a on the touch screen, and then the finger slides from a to B on the touch screen, and performs a lifting action at a position B. The sliding distance of the finger on the touch screen is the distance between a and B.
The preset distance may be a user-defined setting. In a setting mode, the setting can be performed according to the size of the touch screen, specifically, the touch screen is smaller, and then the preset distance can be set to be larger, for example, for the touch screen of the mobile phone, the preset distance can be set to be 50 pixels. If the touch screen is large, the preset distance can be set to be small, for example, the touch screen of the conference tablet is large, and the preset distance can be set to be 5 pixels.
When the sliding distance is smaller than the preset distance, it may be considered that, after the pressing action occurs and before the lifting action occurs, only a short-distance sliding occurs in the contact process between the touch object and the touch screen, and the short-distance sliding may be considered as an error, and at this time, it may be determined that a click event occurs.
When the sliding distance is not less than the preset distance, it can be considered that a longer distance of sliding occurs in the contact process between the touch object and the touch screen after the pressing action occurs and before the lifting action occurs, at this time, it is determined that the sliding action occurs, and it can be determined that the click event does not occur.
In the embodiment, the preset distance is set, so that the short-distance sliding is allowed to occur in the clicking action process, and even if the short-distance sliding occurs in the clicking process, the clicking event can be considered to occur, and the success rate and the fault tolerance rate of the clicking event are improved.
In one embodiment, the sound information may be obtained, and in one implementation, the ambient environment may be monitored in real time to obtain the sound information of the ambient environment.
After the sound information is acquired, the acquired sound information can be matched with the voiceprint information corresponding to the preset knocking event, and if the acquired sound information is matched with the voiceprint information corresponding to the preset knocking event, the sound information belonging to the knocking event can be judged and monitored.
The voiceprint information is preset and can be stored in the device in advance. The voiceprint information is of a tapping event, and therefore, the sound information matched with the voiceprint information can be regarded as the sound information of the tapping event, that is, the sound of the sound information is generated by the tapping event.
In one implementation of the preset voiceprint information, the sound generated by the touch screens made of different materials when the touch screens are knocked is different, that is, the corresponding voiceprint information of the touch screens made of different materials is different. Various voiceprint information can be preset, and each voiceprint information corresponds to the touch screen made of one material. In this case, the acquired sound information may be matched with each piece of voiceprint information, and as long as the acquired sound information can be matched with one piece of voiceprint information, it may be determined that the sound information belonging to the knocking event is monitored.
According to the technical scheme provided by the embodiment of the application, the knocking event can be considered to be the combination of the clicking event and the sound, so that the knocking event can be judged to occur under the conditions that the sound information belonging to the knocking event is monitored, the clicking event is detected, and the time difference between the time of monitoring the sound information and the time of detecting the clicking event is smaller than the first preset time. The scheme can completely eliminate the use of an acceleration sensor, and further realize the detection of the knocking event under the condition without the acceleration sensor.
