The editing software supports touch device input, generally an electronic whiteboard or a touch screen of a terminal, and supports input operations of common touch gestures, such as picture zooming and the like.
Fig. 1 is a flowchart illustrating a method for switching writing, selecting and erasing modes by gestures according to an embodiment of the present invention. The method for switching writing, selecting and erasing modes by utilizing gestures comprises the following steps:
step 101: detecting multi-finger touch information input by a user;
step 102: according to the input multi-finger touch information, judging whether one of a single-finger writing judgment condition, a two-finger selection judgment condition and a five-finger erasing judgment condition is met,
if the single-finger writing judgment condition is met, performing step 103;
if the two-finger selection judgment condition is met, performing step 104;
if the five-finger erasing judgment condition is met, performing step 105;
if any one of the three conditions is not met, the step 101 is repeatedly executed;
step 103: according with the single-finger writing judgment condition, calling a writing function and entering a writing operation mode;
and under the writing operation mode, the selection function is quitted, and the erasing function is quitted.
Step 104: according with the two-finger selection judgment condition, calling a selection function and entering a selection operation mode;
and under the selection of the operation mode, exiting from the writing function and exiting from the erasing function.
Step 105: and (4) according with the five-finger erasing judgment condition, calling an erasing function and entering an erasing operation mode.
And under the erasing operation mode, quitting the writing function and quitting the selecting function.
In the embodiment shown in fig. 1, the single-finger writing determination condition, the two-finger selection determination condition, and the five-finger erasing determination condition are sequentially determined, but this is merely an exemplary illustration, and the order of determination of the three determination conditions is not limited in the present invention.
In step 101, the multi-finger touch information refers to touch information sent to software by the system when the user interacts with the touch input device through a finger, and includes signals of position, time, width, height, pressure, and the like of the touch points.
The touch points can be divided into single-finger touch points, two-finger touch points, three-finger touch points, four-finger touch points, five-finger touch points, and the like according to the number of the touch points.
The touch point position interval refers to an interval between a touch point and another touch point closest to the touch point position.
The touch point time interval refers to a time difference between the touch point falling earliest and the touch point falling latest, that is, a time difference between the first touch point and the last touch point obtained by detection.
In step 102, as shown in fig. 2, the single-finger writing determination condition includes: the first condition is as follows: the number of the touch points is one, namely the touch points are single-finger touch points; and a second condition: the position of the single-finger touch point is not in the range of any two-finger selection gesture area; and (3) carrying out a third condition: the position of the single-finger touch point is not within the range of any five-finger erasing gesture area. If the three conditions are simultaneously met, the condition is judged to be met with the single-finger writing judgment condition, a writing operation mode can be entered, and writing operation can be performed through single-finger touch in the writing operation mode.
In step 102, as shown in fig. 3, the two-finger selection determination condition includes: the first condition is as follows: the number of the touch points is two, namely two finger touch points; and a second condition: the positions of the two-finger touch points are not in the range of any single-finger writing gesture area; and (3) carrying out a third condition: the positions of the two-finger touch points are not in the range of any five-finger erasing gesture area; and a fourth condition: the position distance between the two touch points is larger than the selection position distance, for example, the selection position distance is 40 pixels; and a fifth condition: the time interval between the two touch points is less than or equal to a selection time interval, for example, the selection time interval is 320 milliseconds; and a sixth condition: the two touch points fall on the same object. If the six conditions are simultaneously met, the condition is judged to be met with the two-finger selection judgment condition, a selection operation mode can be entered, and in the selection operation mode, the same object can be selected, dragged and the like through two-finger touch.
In step 102, as shown in fig. 4, the five-finger erase determination condition includes: the first condition is as follows: the number of the touch points is five, namely five-finger touch points; and a second condition: the position of the five-finger touch point is not in the range of any single-finger writing gesture area; and (3) carrying out a third condition: the position of the five-finger touch point is not in the range of any two-finger selection gesture area; and a fourth condition: the position interval of the five-finger touch points (the interval between any one of the five touch points and the touch point closest to the touch point) is less than or equal to the erasing position interval, for example, the erasing position interval is 120 pixels; and a fifth condition: the time interval between the five touch points (the time difference between the first touch point and the fifth touch point) is less than or equal to the erase time interval, for example, the erase time interval is 400 ms. If the five conditions are simultaneously met, the five-finger erasing judgment condition is judged to be met, an erasing operation mode can be entered, and the operation object can be erased through five-finger touch in the erasing operation mode.
In addition, in order to avoid the problem that the data error of the operation object is caused by simultaneously erasing different positions of the same object, for the five-finger erasing judgment condition, a judgment condition six: no other five-finger wipe gesture is in progress. That is, it is specified that only one erase operation is performed by the same object at the same time to ensure the correctness of the operation object data. However, the sixth condition is not a condition that needs to be satisfied for determining that the five-finger erase determination condition is satisfied, and the erase operation may be performed simultaneously for different positions of the same object.
The single-finger writing gesture area range, the two-finger selection gesture area range and the five-finger deletion gesture area range are dynamically determined according to specific operation modes. In particular, the present invention relates to a method for producing,
according to the step 103, after entering the writing operation mode, dynamically determining the single-finger writing gesture area range according to the writing operation range. For example, according to writing habits, a certain area range including a single-finger touch point is determined as a single-finger writing gesture area range.
According to step 104, after entering the selection operation mode, according to the selection operation range, dynamically determining the two-finger selection gesture area range. For example, a region having a certain range, such as a circle or a rectangle, determined from the start point to the end point of the two-finger drag operation is determined as a two-finger selection gesture region range.
According to the step 105, after entering the five-finger erasing mode, the area range of the five-finger erasing gesture is dynamically determined according to the erasing operation range. For example, an area having a certain range, such as a circle determined by a five-finger touch point, is determined as a five-finger erase gesture area range. The five-finger erasing gesture area range determined by the five-finger touch point is used as an eraser for erasing any position of an operation object.
As shown in fig. 5, according to the method of the embodiment of the present invention, on the same touch input device 501, a plurality of operation regions, such as a single-finger writing gesture region 502, a two-finger selecting gesture region 503, and a five-finger erasing gesture region 504, can be simultaneously divided, that is, on the same touch input device, three operations, i.e., writing, selecting, and erasing, can be simultaneously performed. Moreover, the three operations only execute corresponding operations within the gesture area range dynamically determined at this time, the three functions of writing, selecting and erasing are mutually exclusive, only the writing operation can be executed within the single-finger writing gesture area range 502, the selecting and erasing operation cannot be executed, only the selecting operation can be executed within the two-finger selecting gesture area range 503, the writing and erasing operation cannot be executed, only the erasing operation can be executed within the five-finger erasing gesture area range 504, and the writing and selecting operation cannot be executed.
According to the method provided by the embodiment of the invention, the functions of handwriting, selection and erasing can be respectively realized, and the quick switching among the functions of handwriting, selection and erasing can be realized. Specifically, in a writing operation mode, according to multi-finger touch information input in real time, if the two-finger selection judgment condition is judged to be met, the writing operation mode is exited, the selection operation mode is switched to enter, and if the five-finger erasing judgment condition is judged to be met, the writing operation mode is exited, and the erasing operation mode is switched to enter; under the selection operation mode, according to multi-finger touch information input in real time, if the judgment accords with the single-finger writing judgment condition, the selection operation mode is exited, the writing operation mode is switched to enter, and if the judgment accords with the five-finger erasing judgment condition, the selection operation mode is exited, and the erasing operation mode is switched to enter; under the erasing operation mode, according to the multi-finger touch information input in real time, if the judgment accords with the single-finger writing judgment condition, the erasing operation mode is quitted, the writing operation mode is switched to enter, and if the judgment accords with the two-finger selection judgment condition, the erasing operation mode is quitted, and the selecting operation mode is switched to enter. Therefore, the function switching can be realized by corresponding touch gestures without additionally clicking a function button, the three functions of handwriting, selecting and erasing can be quickly switched, the operation is simple and convenient, the response speed is high, and the use is very convenient.
