The embodiment of the application discloses a collaborative input method of an electromagnetic touch digital pen. Referring to fig. 1, as an embodiment of a collaborative input method of an electromagnetic touch digital pen, the collaborative input method of the electromagnetic touch digital pen includes the steps of:
step 101, after the user selects an input mode in a first setting box of the writing device, determining the number N of electromagnetic touch pens to be used based on the selected input mode.
Specifically, the first setting box is a display control, and a plurality of input modes are set in the first control, including: drawing mode and writing mode; the drawing mode further includes: ink painting mode, oil painting mode, water painting mode. The number of pens that have different line thicknesses that need to be used for different input modes is different, and the writing device determines the number N of electromagnetic styluses that need to be used based on the selected input mode.
102, the writing equipment judges whether the number N is larger than 1; if so, configuring a connection entry based on the determined number; the connection inlet is used for connecting N electromagnetic touch pens.
Specifically, the connection inlet is a connection port for connecting the writing equipment and the electromagnetic control pen through Bluetooth, and the electromagnetic touch control pen connected with the writing equipment can be directly displayed in the writing equipment by generating the connection inlet, and equipment information of the electromagnetic touch control pen is read.
Step 103, the writing device records the device information of the connected electromagnetic touch pen.
104, the writing device generates a second setting frame; the second setting frame is used for displaying the connected electromagnetic touch pen and the writing equipment name of the electromagnetic touch pen.
And 105, after the user clicks a confirmation button of the second setting frame, determining the connection of the electromagnetic stylus and the writing device based on the angular velocity data detected by the gyroscope acceleration sensor of the electromagnetic stylus.
Specifically, whether the electromagnetic stylus is in writing is determined by angular velocity data detected by the gyroscope acceleration sensor, and the electromagnetic stylus in writing is connected with the writing device.
According to the application, the number N of the electromagnetic touch pens to be used is determined based on the input mode, when the number N is larger than 1, the connection inlet is configured based on the determined number, and the connection between the electromagnetic touch pen and the writing equipment is determined based on the angular velocity data detected by the gyroscope acceleration sensor of the electromagnetic touch pen, so that electric energy is saved.
As a specific embodiment of the cooperative input method of the electromagnetic touch digital pen, determining the connection of the electromagnetic touch pen with the writing device based on the angular velocity data includes:
judging whether the nth electromagnetic touch pen is in a moving state or not based on the received angular velocity data in a first duration of first connection of the electromagnetic touch pen and the writing equipment;
if so, the connection between the nth electromagnetic touch control pen and the writing equipment is maintained;
if not, suspending the connection between the nth electromagnetic touch pen and the writing equipment; when the nth electromagnetic touch pen recognizes that the nth electromagnetic touch pen is in a motion state based on the angular velocity data, the electromagnetic touch pen broadcasts a connection request to the outside; the connection request contains the equipment information of the nth electromagnetic touch pen; after the writing equipment receives the connection request, identifying equipment information of the electromagnetic touch control pen which is currently requested to be connected based on the connection request; judging whether the device information is one of the recorded device information of the electromagnetic touch pen; if so, establishing connection between the nth electromagnetic touch pen and the writing equipment.
Specifically, judging whether the electromagnetic touch pen is in a moving state or not based on the received angular velocity data in a first time period when the electromagnetic touch pen is first connected with the writing equipment, and if the electromagnetic touch pen is in the moving state, keeping connection; otherwise, the connection is suspended. This helps to avoid disconnection of the electromagnetic stylus when it is moving on the writing device, thereby improving the stability of the connection, while saving electrical energy for electromagnetic styluses that are not in a moving state, which are suspended from connection. When the nth electromagnetic touch pen recognizes that the nth electromagnetic touch pen is in a motion state based on the angular velocity data, the electromagnetic touch pen broadcasts a connection request to the outside, and the connection between the electromagnetic touch pen and the writing equipment can be accurately controlled. After the writing equipment receives the connection request, the equipment information of the electromagnetic touch pen which is currently requested to be connected is identified based on the connection request, and whether the equipment information is one of the recorded equipment information of the electromagnetic touch pen is judged, so that the use confusion caused by the fact that the electromagnetic touch pen which is not connected in advance is avoided.
As a specific embodiment of the cooperative input method of the electromagnetic stylus, after the connection of the nth electromagnetic stylus and the writing device is maintained, the system further includes:
every second time interval, if the nth electromagnetic touch pen recognizes that the nth electromagnetic touch pen is in a motion state based on the angular velocity data, a continuous connection request is sent to the writing equipment; after the writing equipment receives the continuous connection request, the connection between the nth electromagnetic touch pen and the writing equipment is maintained;
if the second time period is longer than the interval, the writing equipment does not receive the continuous connection request, and the connection of the nth electromagnetic touch pen and the writing equipment is suspended.
Specifically, by sending a request to continue connection to the writing device every second period of time after the connection of the nth electromagnetic stylus to the writing device is maintained, the nth electromagnetic stylus can be kept stably connected to the writing device. Meanwhile, by means of the second time interval, the writing equipment can timely receive the continuous connection request, and disconnection caused by delay is avoided. And then, a second time period is reserved, and if the writing equipment does not receive a continuous connection request, the connection of the nth electromagnetic touch pen and the writing equipment is suspended, so that electric energy is saved.
As a specific embodiment of the collaborative input method of the electromagnetic touch digital pen, after the writing device receives the continuous connection request, the system further includes: the writing equipment sends connection feedback information with equipment information; the connection feedback information is used for being identified by an electromagnetic touch pen corresponding to the equipment information;

Specifically, when the electromagnetic stylus pen does not receive the connection feedback information within the first time period, the electromagnetic stylus pen pauses to send the continuous connection request and searches for the beacon signal broadcasted by the writing equipment, so that the electromagnetic stylus pen can be prevented from frequently sending the connection request, and the occupation of network resources is reduced. If the beacon signal is detected, when the nth electromagnetic touch control pen recognizes that the nth electromagnetic touch control pen is in a motion state based on the angular velocity data, a continuous connection request is resent to the writing equipment, so that the electromagnetic touch control pen can be ensured to be in a connectable state all the time, and the connection reliability of the electromagnetic touch control pen and the writing equipment is improved.
