Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.
The method and the device for quickly opening the object by using the gesture are applied to electronic whiteboard software input through touch equipment. The embodiment of the invention is applied to the courseware making process, and the teacher generates the electronic courseware by inserting and editing various editable objects on the electronic courseware editing page.
The electronic whiteboard software supports touch equipment input, and is generally a touch screen of an electronic whiteboard or a handheld terminal; and supports some commonly used gesture input operations such as: point touch dragging of objects, rotation of two-point touch, zooming of objects, sliding track display and the like.
Referring to fig. 1, a flowchart of a method for quickly starting a software function by using a gesture according to an embodiment of the present invention is shown.
The method for quickly starting the software function by using the gesture comprises the following steps:
step 101: presetting a characteristic area on the four edges of the current page;
step 102: detecting three to five point touch control operations which are continuously input by a user and all fall in the characteristic region;
step 103: when all the point touch operations are within a preset time interval and distance interval, entering a quick starting mode;
step 104: in the quick starting mode, further detecting subsequent sliding operation based on the point touch operation, and acquiring direction information of the sliding operation;
step 105: and reading a preset association list according to the direction information, and starting a corresponding software function.
In step 101, a feature region is preset on a current editing page of the electronic whiteboard software, the feature region is a rectangular region connected with four edges of the current page, and the length and the width of the feature region respectively account for 25% of the length and the width of the current page, so as to ensure an operation space for a user to perform gesture input as much as possible.
In step 102, a point touch operation of the user is detected, where the detection conditions are: the number of the continuous inputs falling in the characteristic region is three to five, namely three, four or five touch points falling in the characteristic region are detected. The lower limit of the number of point touch operations, i.e. the setting of three, is to distinguish from some common touch operations such as the point touch dragging object, the rotation of the two-point touch, the zooming object, and the like, so as to avoid the detection conflict and reduce the calculation amount of the detection processing. The upper limit of the number of point touch operations, namely five settings, is based on the operation habit of a human body, and touch operations are generally finished by one hand, so that double-hand operations are avoided, and the operation process is simplified.
In step 103, further determining the three-to-five point touch operations detected in step 102, and determining whether all of the three-to-five point touch operations fall within the feature region; and whether the time interval and the distance interval between any two consecutive point touch operations are both within a preset range. For the time interval, in the present embodiment, the preset time interval is 0-20 ms, that is, for any two consecutive point touch operations, the time difference between the two points touch on the touch screen does not exceed 20 ms; considering that the point touch operation gesture is operated by a single person, the point touch operation is completed by a single finger of a user, the operation is a relatively coherent action, a plurality of fingers fall down simultaneously, and a plurality of fingers can all fall down on the touch screen in a short time. For the distance interval, in this embodiment, the preset distance interval is 0-20 pixels, that is, the difference between the distances between the points falling on the touch screen for any two consecutive point touch operations does not exceed 20 pixels; considering that the point touch operation gesture is operated by a single person, for the completion of point touch by a single finger of a user, points of a plurality of fingers falling on the touch screen are concentrated in a range. And when the two judgment results are yes, namely all the point touch operations are within the preset time interval and distance interval and all the point touch operations are within the characteristic region, entering a quick starting mode.
In step 104, in the fast-on mode, the three-to-five point touch operation detected in step 102 is continuously detected, and it is detected whether the user uses the three-to-five point touch operation as a starting point, so as to form a sliding operation gesture. When the user inputs the above-mentioned sliding operation, further, the direction information of the sliding operation is acquired, that is, the sliding operation is continuously monitored, the moving direction of the sliding operation relative to the initial position thereof at the end thereof is acquired, whether the sliding operation is upward, downward, leftward or rightward is judged, and the direction is determined as the direction information of the sliding operation.
In step 105, a preset association list is read according to the direction information of the sliding operation acquired in step 104. The association list stores the corresponding relationship between the direction information of the sliding operation and the software functions, specifically, the direction information of the sliding operation, that is, the upper, lower, left, and right correspond to the functions of four commonly used electronic whiteboard software, for example, the screen locking function is triggered by the leftward sliding operation, and the upward sliding operation is triggered. After the association list is read to obtain the corresponding association relationship, the corresponding software function is started according to the direction information obtained in step 104.
In this embodiment, taking three-point touch operation as an example, the whole operation process of the user is as follows: and touching the touch screen by three fingers, and enabling the three points to fall into a preset first characteristic area near the edge of an editing page in the electronic whiteboard software, and entering a quick opening mode at the moment. And the user continues to form a sliding gesture based on the three-point touch operation to complete a leftward sliding operation, and at the moment, the screen locking function is triggered according to a preset association list, so that the software function is quickly started.
Referring to fig. 2, a flowchart of a method for quickly starting a software function by using a gesture according to another embodiment of the present invention is shown.
As another embodiment, the method for quickly starting the software function by using the gesture comprises the following steps:
step 201: presetting a characteristic area on the four edges of the current page;
step 202: detecting three to five point touch control operations which are continuously input by a user and all fall in the characteristic region;
step 203: and restoring all touch operation effects triggered in the process of entering the quick starting mode.
When the touch screen enters the fast starting mode, the point touch operations fall on the touch screen in sequence, and meanwhile, because the fingers fall on the touch screen to generate small movements which are difficult to be perceived by a user, in the process that the point touch operations fall in sequence, the point touch operations which fall in sequence are likely to be recognized as other conventional gesture touch operations. For example, when the first point touch operation falls and slightly moves, the first point touch operation is recognized as a sliding track display gesture, and a small section of track is generated on the current page; if the point touch operation falls on the editable object, and the second point touch operation falls and slightly moves relative to the first point touch operation, the second point touch operation is recognized as a zooming gesture, and the first editable object is zoomed. In order to avoid the above problem, in this step, all touch operation effects triggered in the process of entering the fast-on mode are restored, that is, the above moving and zooming effects are all cancelled.
Step 204: when all the point touch operations are within a preset time interval and distance interval, entering a quick starting mode;
step 205: in the quick starting mode, further detecting subsequent sliding operation based on the point touch operation, and acquiring direction information of the sliding operation;
in this embodiment, the process of acquiring the direction information of the sliding operation specifically includes: and respectively taking the connecting line of the starting point and the end point of the sliding operation as the horizontal and vertical components, and determining the larger value as the direction of the sliding operation. The sliding operation input by the user is not strictly in the horizontal and vertical directions, so that the direction of the sliding operation is required to be further determined, and the direction trend of the sliding operation can be determined by performing vertical projection in the horizontal and vertical directions, taking the corresponding components and taking the larger component. For example, if the sliding operation slides to the upper left and further to the left, the component in the horizontal direction thereof will be larger than the vertical component, and the direction of the sliding operation is determined to be to the left.
Step 206: reading a preset association list according to the direction information, and starting a corresponding software function;
in this embodiment, the association list allows a user to access and perform an editing operation, and the user can input a modification instruction to redefine an association relationship between the direction information of the sliding operation and the software function.
Step 207: and when the point touch operation falling into the characteristic region is completely finished, exiting the quick starting mode.
Since the point touch operation may be terminated due to the shaking of the user's finger or the shaking of the touch screen device, the determination condition for exiting the quick-start mode is set such that all the point touch operations falling within the characteristic region are terminated in order to avoid the above-mentioned erroneous operation.
The embodiment of the invention also provides a device for quickly starting the software function by using the gesture, and the device is a schematic structural diagram of the device for quickly starting the software function by using the gesture according to the embodiment of the invention with reference to fig. 3.
