Description
本发明涉及终端设备技术领域，尤其涉及一种检测触摸方式的方法及装置。The present invention relates to the technical field of terminal equipment, in particular to a method and device for detecting a touch mode.
随着触摸屏式智能终端技术的迅速发展，触摸屏上可用的触摸手势变得越来越丰富，比如手指滑动触摸、手指点击触摸、单指触摸、双指触摸等，不同的触摸手势指示了不同的触摸指令。为了进一步丰富触摸手势，满足触摸指令越来越多的需求，出现了对手指触摸和指关节触摸两种触摸方式的区分。比如，当用户用手指点击一幅图片时，图片会正常打开；而用指关节点击时，则会弹出该图片的菜单选项功能，就如点击电脑鼠标右键那样。With the rapid development of touch screen smart terminal technology, more and more touch gestures are available on the touch screen, such as finger slide touch, finger click touch, single finger touch, two finger touch, etc. Different touch gestures indicate different Touch commands. In order to further enrich touch gestures and meet the increasing demand for touch commands, a distinction has been made between finger touch and knuckle touch. For example, when a user clicks a picture with a finger, the picture will open normally; and when the user clicks with a knuckle, the menu option function of the picture will pop up, just like clicking the right button of a computer mouse.
针对手指触摸和指关节触摸两种触摸方式，主要通过触摸屏的触摸信号，如电容信号，以及加速度传感器在Z轴方向的加速度值来区分，比如，当检测到的电容信号所指示的最大电容值较大、且加速度传感器在Z轴方向的最大加速度值较小时，将触摸方式识别为手指触摸，相反，当检测到的电容信号所指示的最大电容值较小、且加速度传感器在Z轴方向的最大加速度值较大时，将触摸方式识别为指关节触摸。For the two touch methods of finger touch and knuckle touch, it is mainly distinguished by the touch signal of the touch screen, such as the capacitance signal, and the acceleration value of the acceleration sensor in the Z-axis direction, for example, when the maximum capacitance value indicated by the detected capacitance signal Larger and the maximum acceleration value of the acceleration sensor in the Z-axis direction is small, the touch method is recognized as a finger touch. On the contrary, when the maximum capacitance value indicated by the detected capacitance signal is small and the acceleration sensor in the Z-axis direction When the maximum acceleration value is large, the touch method is recognized as a knuckle touch.
但是，触摸屏的触摸信号和加速度信号经常会受到终端设备内和设备外、除真实用户的触摸之外的环境因素的影响，从而导致检测出的触摸方式出错，进而导致终端设备执行了错误的执行指令。However, the touch signal and acceleration signal of the touch screen are often affected by environmental factors other than the real user's touch inside and outside the terminal device, which leads to errors in the detected touch method, which in turn leads to wrong execution of the terminal device. instruction.

具体地，在上述各种具体的补偿参数信息中：Specifically, in the above-mentioned various specific compensation parameter information:
对于马达振动状态补偿信息：当触摸事件同时有马达振动事件，此时用于检测触摸方式的加速度信号为触摸事件在Z轴方向的加速度信号与马达振动产生的Z轴方向的加速度信号的叠加信号；因此马达振动产生的Z轴方向的加速度信号则构成了检测触摸事件的干扰信号，基于带有干扰信号的加速度信号检测触摸方式会影响检测结果的正确性，因此需要在所述带有干扰信 号的加速度信号中过滤掉干扰成分，这里的干扰成分即为：马达振动产生的Z轴方向的加速度信号，基于过滤掉马达振动产生的Z轴方向的加速度信号后的加速度信号检测触摸方式以保证触摸方式检测的正确性。如图2(a)所示，为手指触摸时的重力传感器的信号波形图，图2(b)所示，为指关节触摸时的重力传感器的信号波形图，图2(c)所示，为马达振动时产生的周期性的振动信号波形示意图，一旦该振动信号与图2(a)所示手指触摸时的信号叠加，形成如图2(d)所示信号波形，就可能导致叠加后的信号可以表征指关节触摸方式，从而导致检测的触摸方式出错。因此，针对这种情况，可以在Z轴方向的加速度信号中过滤掉马达振动产生的干扰信号(马达振动产生的Z轴方向的加速度信号)，如图2(e)所示，再基于调整后的Z轴方向的加速度信号，以及所述触摸信号，确定在所述触摸屏上产生的触摸方式。For motor vibration state compensation information: when there is a motor vibration event at the same time as the touch event, the acceleration signal used to detect the touch mode at this time is the superposition signal of the acceleration signal in the Z-axis direction of the touch event and the acceleration signal in the Z-axis direction generated by motor vibration ; Therefore, the acceleration signal in the Z-axis direction generated by the motor vibration constitutes an interference signal for detecting a touch event, and the detection of a touch method based on an acceleration signal with an interference signal will affect the correctness of the detection result. The interference component is filtered out of the acceleration signal of the signal, and the interference component here is: the acceleration signal in the Z-axis direction generated by the motor vibration, and the touch mode is detected based on the acceleration signal after filtering out the acceleration signal in the Z-axis direction generated by the motor vibration to ensure Correctness of touch detection. As shown in Figure 2 (a), it is the signal waveform diagram of the gravity sensor when the finger touches, as shown in Figure 2 (b), it is the signal waveform diagram of the gravity sensor when the knuckle is touched, as shown in Figure 2 (c), It is a schematic diagram of the periodic vibration signal waveform generated when the motor vibrates. Once the vibration signal is superimposed with the signal when the finger is touched as shown in Figure 2(a), the signal waveform shown in Figure 2(d) is formed, which may cause the superimposed The signal of the knuckle can represent the touch pattern of the knuckle, causing the detected touch pattern to be wrong. Therefore, in view of this situation, the interference signal generated by the motor vibration (the acceleration signal in the Z-axis direction generated by the motor vibration) can be filtered out from the acceleration signal in the Z-axis direction, as shown in Figure 2(e), and then based on the adjusted The acceleration signal in the Z-axis direction and the touch signal determine the touch mode generated on the touch screen.
对于音视频播放状态补偿信息：当触摸事件同时有音视频播放事件，此时用于检测触摸方式的加速度信号为触摸事件在Z轴方向的加速度信号与音视频播放产生的Z轴方向的加速度信号的叠加信号；音视频播放产生的Z轴方向的加速度信号则构成了检测触摸事件的干扰信号，需要在所述带有干扰信号的Z轴方向的加速度信号中过滤掉干扰成分，这里的干扰成分即为：音视频播放产生的Z轴方向的加速度信号，基于过滤掉音视频播放产生的Z轴方向的加速度信号后的加速度信号检测触摸方式以保证触摸方式检测的正确性。由于音视频的频率以及响度的不同，音视频播放产生的Z轴方向的加速度信号也不同，所述音视频播放产生的Z轴方向的加速度信号可以是预先设置的，也可以随着音视频播放动态调节。For audio and video playback state compensation information: when a touch event has an audio and video playback event at the same time, the acceleration signal used to detect the touch method at this time is the acceleration signal of the touch event in the Z-axis direction and the acceleration signal in the Z-axis direction generated by audio and video playback. The superimposed signal; the acceleration signal in the Z-axis direction generated by audio and video playback constitutes an interference signal for detecting touch events, and it is necessary to filter out interference components in the acceleration signal in the Z-axis direction with interference signals. The interference components here That is: the acceleration signal in the Z-axis direction generated by audio and video playback, and the touch method is detected based on the acceleration signal after filtering the acceleration signal in the Z-axis direction generated by audio and video playback to ensure the correctness of the touch method detection. Due to the difference in frequency and loudness of audio and video, the acceleration signals in the Z-axis direction generated by audio and video playback are also different. The acceleration signals in the Z-axis direction generated by the audio and video playback can be preset, or can be played along Dynamic adjustment.
对于角速度传感器的信号补偿信息：角速度传感器可以感应终端设备的移动方向，例如左转右转。当终端做圆形轨迹运动(比如用户乘坐旋转木马)时，角速度传感器会产生角速度信号，也即离心力信号，当角速度信号在Z轴方向有分量时，用于检测触摸方式的加速度信号为触摸事件在Z轴方向的加速度信号与Z轴方向的角速度信号的叠加信号；Z轴方向的角速度信号则构成了检测触摸事件的干扰信号，需要在所述带有干扰信号的加速度信号中 过滤掉干扰成分，这里的干扰成分即为：Z轴方向的角速度信号，基于过滤掉Z轴方向的角速度信号后的加速度信号检测触摸方式以保证触摸方式检测的正确性。For the signal compensation information of the angular velocity sensor: the angular velocity sensor can sense the moving direction of the terminal device, such as turning left and turning right. When the terminal moves on a circular trajectory (such as a user riding a carousel), the angular velocity sensor will generate an angular velocity signal, that is, a centrifugal force signal. When the angular velocity signal has a component in the Z-axis direction, the acceleration signal used to detect the touch method is a touch event. The superposition signal of the acceleration signal in the Z-axis direction and the angular velocity signal in the Z-axis direction; the angular velocity signal in the Z-axis direction constitutes an interference signal for detecting touch events, which needs to be included in the acceleration signal with the interference signal Filter out the interference components, where the interference components are: the angular velocity signal in the Z-axis direction, and detect the touch mode based on the acceleration signal after filtering out the angular velocity signal in the Z-axis direction to ensure the correctness of the touch mode detection.
当接近光传感器被物体遮挡住或者处于黑暗的环境时，会输出一个“遮挡”信号，利用接近光传感器可以对终端设备的工作状态进行识别，比如，当接近光传感器被遮挡时，用户很有可能在打电话，或者将触摸屏靠近了头部或者脸部，此时如果用户的耳朵或者头骨碰到触摸屏，就会发生触摸事件，而显然，这时候的触摸都是误触摸，因此，通过接近光传感器输出的“遮挡”信号，可以确定所述终端设备处于非主动触摸状态，即产生的触摸事件不是用户主动触摸，可以忽略此次触摸事件，不进行触摸方式的识别。When the proximity light sensor is blocked by an object or in a dark environment, it will output a "blocking" signal. The proximity light sensor can be used to identify the working status of the terminal device. For example, when the proximity light sensor is blocked, the user is very You may be making a phone call, or bring the touch screen close to your head or face. At this time, if the user's ear or skull touches the touch screen, a touch event will occur. Obviously, the touch at this time is a false touch. Therefore, by approaching The "blocking" signal output by the light sensor can determine that the terminal device is in the non-active touch state, that is, the generated touch event is not the user's active touch, and the touch event can be ignored without identifying the touch mode.
同理，当环境光传感器周围没有光的时候，环境光传感器会输出一个“暗”的信号，利用环境光传感器可以对终端设备的工作状态进行识别，比如，当环境光传感器被遮挡时，终端设备可能是被放在包里，此时若用户的钥匙或者硬币触碰触摸屏，就会发生触摸事件，显然，这时候产生的触摸事件不是用户主动触摸，因此，通过环境光传感器输出的“暗”信号，可以确定终端设备处于非主动触摸状态，可以忽略此次触摸事件，不进行触摸方式的识别。Similarly, when there is no light around the ambient light sensor, the ambient light sensor will output a "dark" signal, and the ambient light sensor can be used to identify the working status of the terminal device. For example, when the ambient light sensor is blocked, the terminal The device may be placed in a bag. At this time, if the user's key or coin touches the touch screen, a touch event will occur. Obviously, the touch event generated at this time is not the user's active touch. Therefore, the "dark" output through the ambient light sensor ” signal, it can be determined that the terminal device is in the non-active touch state, and the touch event can be ignored, and the touch method will not be identified.
基于上述描述内容，在S102的具体执行过程中，基于所述第一参数信息对所述Z轴方向的加速度信号进行调整，包括：Based on the above description, in the specific execution process of S102, the acceleration signal in the Z-axis direction is adjusted based on the first parameter information, including:
当所述第一参数信息包括所述马达振动状态补偿信息时，在所述Z轴方向的加速度信号中过滤掉因马达振动产生的Z轴方向的加速度信号；When the first parameter information includes the motor vibration state compensation information, filtering the acceleration signal in the Z-axis direction due to motor vibration from the acceleration signal in the Z-axis direction;
当所述第一参数信息包括所述音视频播放状态补偿信息时，在所述Z轴方向的加速度信号中过滤掉因音视频播放产生的Z轴方向的加速度信号；When the first parameter information includes the audio and video playback state compensation information, filter out the acceleration signal in the Z axis direction due to audio and video playback from the acceleration signal in the Z axis direction;
当所述第一参数信息包括所述角速度传感器的信号补偿信息时，在所述Z轴方向的加速度信号中过滤掉Z轴方向的角速度信号。When the first parameter information includes signal compensation information of the angular velocity sensor, the angular velocity signal in the Z-axis direction is filtered out from the acceleration signal in the Z-axis direction.
以下实施例为体现上述思想的一个较具体的实施例。The following embodiment is a more specific embodiment embodying the above idea.
如图3所示，为本发明另一实施例提供的检测触摸方式的方法流程图，包括以下步骤： As shown in FIG. 3 , it is a flowchart of a method for detecting a touch mode provided by another embodiment of the present invention, including the following steps:
S301：当检测到来自触摸屏的触摸信号后，确定加速度传感器输出的Z轴方向的加速度信号，以及影响对作用于所述触摸屏上的触摸方式的检测的第一参数信息和第二参数信息；所述第一参数信息用于调整所述Z轴方向的加速度信号，包括马达振动状态补偿信息、音视频播放状态补偿信息、和角速度传感器的信号补偿信息中的一种或多种；所述第二参数信息用于确定所述终端设备的工作状态，所述第二参数信息包括接近光传感器的信号状态信息和/或环境光传感器的信号状态信息。S301: After detecting the touch signal from the touch screen, determine the acceleration signal in the Z-axis direction output by the acceleration sensor, and the first parameter information and the second parameter information that affect the detection of the touch method acting on the touch screen; The first parameter information is used to adjust the acceleration signal in the Z-axis direction, including one or more of motor vibration state compensation information, audio and video playback state compensation information, and angular velocity sensor signal compensation information; the second The parameter information is used to determine the working state of the terminal device, and the second parameter information includes signal state information of the proximity light sensor and/or signal state information of the ambient light sensor.
S302：在基于所述第二参数信息确定所述终端设备处于非主动触摸状态时，不对作用于所述触摸屏上的触摸方式进行识别，在基于所述第二参数信息确定所述终端设备处于主动触摸状态时，基于所述第一参数信息对所述Z轴方向的加速度信号进行调整。S302: When it is determined based on the second parameter information that the terminal device is in a non-active touch state, do not identify the touch mode acting on the touch screen, and when it is determined based on the second parameter information that the terminal device is in an active touch state In the touch state, the acceleration signal in the Z-axis direction is adjusted based on the first parameter information.
该步骤中，基于接近光传感器和/或环境光传感器输出的指示被遮挡的信号，可以获知在产生触摸信号的时间范围内是否终端设备处于非主动触摸状态(终端设备当前不会出现用户主动触摸所述触摸屏的情况)，若终端设备处于非主动触摸状态，说明此次触摸事件为误触摸，不对触摸方式进行识别，若终端设备处于主动触摸工作状态，则基于第一参数信息对Z轴方向的加速度信号进行调整。具体地，在Z轴方向的加速度信号中，过滤掉干扰信号，比如马达振动时产生的Z轴方向的加速度信号、音视频播放产生的Z轴方向的加速度信号、终端设备内设置的角速度传感器输出的Z轴方向的角速度信号。In this step, based on the signal indicating that the proximity light sensor and/or the ambient light sensor output is blocked, it can be known whether the terminal device is in the non-active touch state within the time range when the touch signal is generated (the terminal device currently does not appear to be actively touched by the user) In the case of the touch screen), if the terminal device is in the non-active touch state, it means that the touch event is a false touch, and the touch mode is not identified. If the terminal device is in the active touch working state, then based on the first parameter information, the Z-axis direction The acceleration signal is adjusted. Specifically, in the acceleration signal in the Z-axis direction, the interference signal is filtered out, such as the acceleration signal in the Z-axis direction generated when the motor vibrates, the acceleration signal in the Z-axis direction generated by audio and video playback, and the angular velocity sensor output in the terminal device. The angular velocity signal in the direction of the Z axis.
S303：基于检测到的触摸信号和调整后的Z轴方向的加速度信号，确定作用于所述触摸屏上的触摸方式。S303: Determine a touch manner acting on the touch screen based on the detected touch signal and the adjusted acceleration signal in the Z-axis direction.
该步骤中，如果确定终端设备处于主动触摸工作状态，基于来自触摸屏的触摸信号及调整后的Z轴方向的加速度信号，确定作用于所述触摸屏上的触摸方式是手指触摸，还是指关节触摸。比如，当触摸屏为电容式触摸屏时，可以基于获取的触摸信号确定电容值分布信息(各个网格内分布的电容值)，并基于调整后的Z轴方向的加速度信号确定Z轴方向的加速度值，基于确定 的电容值分布信息和加速度值，确定触摸方式。比如，当确定的电容值分布信息中指示最大电容值在第一设定范围内(比如大于0.42pF、小于或等于0.46pF)，并且分布有非零电容值的网格个数大于或等于7，在设定时间段内，加速度最大值小于设定的阈值(比如，在5ms内，加速度最大值为2g，小于设定的阈值3g，g为重力加速度)时，确定该触摸方式为手指触摸；当确定的电容值分布信息中指示最大电容值在第二设定范围内(比如小于或等于0.42pF)，分布有非零电容值的网格个数小于7，在设定时间段内，加速度最大值大于设定的阈值(比如为3g)时，确定该触摸方式为指关节触摸。In this step, if it is determined that the terminal device is in an active touch working state, based on the touch signal from the touch screen and the adjusted acceleration signal in the Z-axis direction, determine whether the touch mode acting on the touch screen is finger touch or knuckle touch. For example, when the touch screen is a capacitive touch screen, the capacitance value distribution information (capacitance value distributed in each grid) can be determined based on the acquired touch signal, and the acceleration value in the Z-axis direction can be determined based on the adjusted acceleration signal in the Z-axis direction , based on determining The capacitance value distribution information and the acceleration value of the sensor determine the touch mode. For example, when the determined capacitance value distribution information indicates that the maximum capacitance value is within the first set range (such as greater than 0.42pF, less than or equal to 0.46pF), and the number of grids with non-zero capacitance values distributed is greater than or equal to 7 , within the set time period, when the maximum acceleration value is less than the set threshold value (for example, within 5ms, the maximum acceleration value is 2g, which is less than the set threshold value 3g, and g is the acceleration of gravity), determine that the touch method is finger touch ; When the determined capacitance value distribution information indicates that the maximum capacitance value is within the second set range (for example, less than or equal to 0.42pF), the number of grids with non-zero capacitance values distributed is less than 7, and within the set time period, When the maximum value of the acceleration is greater than a set threshold (for example, 3g), it is determined that the touch mode is knuckle touch.
