Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
In the embodiment of the invention, the Touch gesture is recognized based on a Multi-Touch Protocol (MTP).
In the embodiment of the present invention, as shown in fig. 1, the detailed method flow of touch gesture recognition is as follows:
step 101: the method comprises the steps of monitoring the coordinate change of the center point of the contact surface of at least one finger and the touch screen in the touch screen operation process, and monitoring the change of the long axis and/or the short axis of the contact surface of the at least one finger and the touch screen.
In a specific implementation, the touch screen obtains a touch event after detecting that a finger contacts the touch screen, and the touch event may be represented by any one or a combination of the following identifiers:
the X-axis coordinate of the contact surface center point, expressed as ABS _ MT _ POSITION _ X event;
the Y-axis coordinate of the contact surface center point, expressed as an ABS _ MT _ POSITION _ Y event;
a contact patch MAJOR axis value, denoted as ABS _ MT _ TOUCH _ MAJOR event;
the contact patch MINOR axis value, denoted as ABS _ MT _ TOUCH _ MINOR event.
Wherein if the contact surface is circular, the influence of the minor axis value of the contact surface is not considered; if the contact surface is elliptical, then the major axis value of the contact surface and the minor axis value of the contact surface need to be considered.
The ratio of the major axis value of the contact surface to the minor axis value of the contact surface reflects the magnitude of the contact surface pressure.
The change of the long axis value of the contact surface and/or the change of the short axis value of the contact surface can reflect the change of an included angle between the finger and the touch screen.
In the embodiment of the invention, at least one finger can be simultaneously contacted with the touch screen.
Step 102: and identifying a touch gesture corresponding to the touch screen operation according to the change of the coordinate of the central point and the change of the long axis value of the contact surface.
In a specific implementation, if the ABS _ MT _ TOUCH _ MAJOR event changes, it indicates that the action of pressing the TOUCH screen by the finger changes one of the following changes:
1. the pressure of the finger pressing the touch screen changes;
2. the pressure of the finger pressing the touch screen does not change, but the angle between the finger and the touch screen changes.
In a specific implementation, if the ABS _ MT _ POSITION _ X event changes, the X-axis coordinate of the center point of the contact surface between the finger and the touch screen changes.
In a specific implementation, if the ABS _ MT _ POSITION _ Y event changes, the Y-axis coordinate of the center point of the contact surface between the finger and the touch screen changes.
Specifically, the touch gesture corresponding to the touch screen operation is identified according to the change of the coordinates of the central point and the change of the long axis value of the contact surface, which includes but is not limited to the following two specific embodiments:
first embodiment
If it is determined that the variation of the abscissa in the central point coordinate is smaller than a first preset threshold, the variation of the ordinate in the central point coordinate is smaller than a second preset threshold, and the variation of the long axis value of the contact surface is not smaller than a third preset threshold, it is determined that the touch screen operation is that the pressing force of the finger on the touch point changes, and the touch screen operation is identified as a touch screen gesture corresponding to the change of the pressing force.
Optionally, in the first embodiment, the recognizing the touch screen operation as the touch screen gesture corresponding to the change of the pressing force degree may specifically be:
determining at least one touch gesture corresponding to the change of the pressing force degree after the touch screen operation is determined to be the change of the pressing force degree of the finger to the touch point;
selecting touch gestures corresponding to the number of fingers from the at least one determined touch gesture according to the number of the fingers contacting the touch screen, and taking the selected touch gestures as finally recognized touch gestures; alternatively, the first and second electrodes may be,
and selecting a touch gesture corresponding to the number of the fingers with the changed pressing strength from the at least one determined touch gesture according to the number of the fingers with the changed pressing strength in the fingers contacting the touch screen, and taking the selected touch gesture as the finally recognized touch gesture.
In the first embodiment, if the variation of the ABS _ MT _ TOUCH _ MAJOR event and/or the ABS _ MT _ TOUCH _ MINOR event is not less than the third preset threshold, i.e., is changed greatly, while the variation of the ABS _ MT _ POSITION _ X event is less than the first preset threshold, and the variation of the ABS _ MT _ POSITION _ Y event is less than the second preset threshold, i.e., the variations of the ABS _ MT _ POSITION _ X event and the ABS _ MT _ POSITION _ Y event are small, it is considered that only the pressing force degree between the finger and the TOUCH screen is changed, and the contact POSITION between the finger and the TOUCH screen is not changed. In this case, the touch operation may be recognized as a touch gesture corresponding to the pressure strength change.
In the first embodiment, after the touch operation is recognized as the touch gesture corresponding to the pressure force change, a more accurate touch gesture can be further determined according to the number of fingers simultaneously contacting the touch screen.
For example, if there are multiple touch gestures corresponding to changes in the pressure of the fingers on the contact surface, one touch gesture is selected from the multiple touch gestures according to the number of fingers simultaneously contacting the touch screen. Assuming that the number of fingers simultaneously in contact with the touch screen is 2, selecting the touch gesture corresponding to the 2 fingers from multiple touch gestures corresponding to the change of the pressure force of the fingers on the contact surface.
Second embodiment
If the change of the long axis value of the contact surface is larger than a third threshold value, the variation of the abscissa in the central point coordinate is not smaller than the first preset threshold value, and/or the variation of the ordinate in the central point coordinate is not smaller than a second preset threshold value, determining that the touch screen operation is a finger shaking operation, and identifying the touch screen operation as a touch screen gesture corresponding to the finger shaking operation.
Optionally, in the second embodiment, a shaking direction of the finger shaking operation may be determined according to a changing direction of the center point coordinate, and a touch screen gesture corresponding to the shaking direction of the finger shaking operation in the touch screen operation is identified.
Optionally, in the second embodiment, the identifying the touch screen operation as a touch gesture corresponding to the change of the coordinates of the central point and the change of the long axis of the contact surface specifically includes:
determining at least one touch gesture according to the change of the coordinates of the central point and the change of the long axis value of the contact surface;
and identifying a touch gesture corresponding to the touch screen operation from the at least one determined touch gesture according to the number of fingers in contact with the touch screen.
Optionally, in a second embodiment, the identifying the touch screen operation as a touch gesture corresponding to the change of the coordinates of the central point and the change of the long axis of the contact surface specifically includes:
determining at least one touch gesture according to the change of the coordinates of the central point and the change of the long axis value of the contact surface, and determining the number of fingers subjected to finger shaking operation;
and identifying a touch gesture corresponding to the touch screen operation from the at least one determined touch gesture according to the number of fingers which are subjected to finger shaking operation in the fingers which are in contact with the touch screen.
In the second embodiment, if the variation of the ABS _ MT _ TOUCH _ MAJOR event and/or the ABS _ MT _ TOUCH _ MINOR event is not less than the third preset threshold, i.e. the variation is large, and the variation of the ABS _ MT _ POSITION _ X event is not less than the first preset threshold, and the variation of the ABS _ MT _ POSITION _ Y event is not less than the second preset threshold, i.e. the variation of the ABS _ MT _ POSITION _ X event and the ABS _ MT _ POSITION _ Y event is large, the angle between the finger and the TOUCH screen is considered to be changed.
Also, the direction of the shaking of the finger can be determined based on the initial coordinates of the center point of the contact surface, denoted as [ ABS _ MT _ POSITION _ X _ ORG, ABS _ MT _ POSITION _ Y _ ORG ], and the coordinates of the center point of the contact surface after the change, denoted as [ ABS _ MT _ POSITION _ X, ABS _ MT _ POSITION _ Y ]. That is, the direction of the finger swing is a direction from [ ABS _ MT _ POSITION _ X _ ORG, ABS _ MT _ POSITION _ Y _ ORG ] to [ ABS _ MT _ POSITION _ X, ABS _ MT _ POSITION _ Y ].
In the second embodiment, after the touch operation is recognized as the touch gesture corresponding to the finger shaking, a more accurate touch gesture can be further determined according to the number of fingers simultaneously in contact with the touch screen.
For example, if the finger shaking corresponds to a plurality of touch gestures, the plurality of touch gestures respectively correspond to different numbers of fingers, and if the number of fingers simultaneously contacting the touch screen is 2, a touch gesture corresponding to the number of fingers 2 is selected from the plurality of touch gestures.
The touch gesture recognition method provided by the embodiment of the invention can be applied to any intelligent equipment, and each application in the intelligent equipment can define the corresponding relation between the recognized touch gesture and the function.
