and 101, instructing a controller of the detection device to receive an input instruction, generating a communication instruction according to the input instruction and sending the communication instruction to a wireless communication module.

In a specific process, when a user uses the indication detection device and the pen pointer to perform input operation, the user sends an input instruction to a controller of the indication detection device by touching a touch screen of the indication detection device through a pen point of the pen pointer, the controller analyzes the input instruction after receiving the input instruction, generates a communication instruction according to the input instruction, and sends the communication instruction to the wireless communication module, so that the wireless communication module is controlled to perform the next action.

And 102, the wireless communication module receives indication attribute information sent by the pen indicator according to the communication instruction.

The indication attribute information comprises the pressed times and the pressed duration of the function keys of the pen indicator.

Specifically, the wireless communication module starts wireless communication with the pen pointer according to the communication instruction; the controller judges whether the wireless communication between the wireless communication module and the pen indicator is normally connected.

If the wireless communication connection between the wireless communication module and the pen indicator is normal, the controller generates a signal receiving instruction and sends the signal receiving instruction to the wireless communication module; the wireless communication module receives indication attribute information wirelessly transmitted by the pen indicator according to the signal receiving instruction.

If the wireless communication connection between the wireless communication module and the pen indicator is abnormal, the controller generates a prompt instruction and sends the prompt instruction to the display; and the display generates prompt information according to the prompt instruction and displays the prompt information.

Preferably, the function module of the pen indicator detects the key operation of the function key within the preset time; the function module generates indication attribute information according to the key operation and sends the indication attribute information to a wireless sending module of the pen indicator; the wireless sending module sends the indication attribute information to the wireless communication module; the wireless communication module receives the indication attribute information according to the signal receiving instruction.

In a specific process, in order to ensure that data transmission can be normally performed between the wireless communication module and the pen pointer, that is, to ensure that the wireless communication module can receive functional information data, before the controller controls the wireless communication module to receive data, after the wireless communication module starts performing wireless communication with the pen pointer according to a communication instruction, whether wireless communication between the wireless communication module and the pen pointer is normally connected is determined.

If the wireless communication connection between the wireless communication module and the pen indicator is normal, the wireless data transmission between the wireless communication module and the pen indicator can be carried out, and at the moment, the controller generates a signal receiving instruction and sends the signal receiving instruction to the wireless communication module, so that the wireless communication module is controlled to carry out data receiving action next. Before the wireless communication module completes the data receiving action, the functional module of the pen indicator needs to detect the pressing times and the pressing duration of the functional key within a certain time, generate indication attribute information according to the detection result, send the indication attribute information to the wireless transmitting module, and perform wireless transmission between the wireless transmitting module and the wireless communication module of the indication detection device, so that the wireless communication module completes the receiving action of the indication attribute information.

If the wireless communication connection between the wireless communication module and the pen indicator is abnormal, the wireless transmission module of the pen indicator does not start the transmission function or the pen indicator is in an inoperative state, so that information prompt needs to be carried out on a user, and the user is reminded to carry out state check on the pen indicator. In detail, the controller generates a prompt instruction according to the judgment result, sends the generated prompt instruction to the display, the display analyzes the prompt instruction, and the display generates prompt information and displays the prompt information to prompt a user. Preferably, the prompt message is embodied as "failure of wireless communication connection between the wireless communication module and the pen pointer".

And 104, the controller analyzes the indication attribute information and extracts the pressed times in the indication attribute information.

In a specific process, the controller receives and analyzes the indication attribute information, and extracts the pressed times in the indication attribute information, so that whether the indication operation is a selection operation is judged according to the pressed times, if the pressed times is one, the indication operation may be an erasing operation or a handwriting input operation, if the pressed times is two, the indication operation is a selection operation, and if the pressed times exceeds two, the indication operation is regarded as an initial default operation.

In step 105, the controller determines whether the number of times the pen pointer is pressed is one.

In a specific process, in order to distinguish the indication operation of the pen indicator, the controller firstly judges whether the pressed times of the pen indicator is one time, if so, further judgment is carried out according to the pressed time length, and if not, the next judgment is carried out on the pressed times.

If the number of times of pressing is one, step 106 is entered; if the number of times of pressing is not one, step 114 is entered.

And 106, the controller extracts the pressed time length in the indication attribute information and extracts a preset time threshold value in the memory.

In a specific process, when the controller judges that the number of times of pressing of the pen indicator is one, the controller extracts the pressed time length in the indication attribute information, and the controller further judges and analyzes the indication operation according to the pressed time length.

In step 107, the controller determines whether the pressed time period is greater than a time threshold.

In a specific process, the controller judges whether the pressed time length is greater than a time threshold, if the pressed time length is greater than the time threshold, the indication operation input by the user is a wiping operation, and if the pressed time length is not greater than the time threshold, the indication operation input by the user is a handwriting input operation.

The preset time threshold may be set by the user according to the usage habit of the user, for example, the time threshold is set to 3 seconds.

If the pressed time is longer than the time threshold, entering step 108; if the pressed time period is not greater than the time threshold, step 117 is entered.

And step 108, the controller generates a deletion operation signal, generates a specific display instruction according to the deletion operation signal and sends the specific display instruction to the display.

In a specific process, the controller generates a deletion operation signal according to the judgment result, generates a specific display instruction for controlling the display to perform display operation according to the deletion operation signal, and then sends the specific display instruction to the display.

And step 109, the controller generates an identification instruction according to the input instruction and sends the identification instruction to the position detection module.

In a specific process, the controller generates an identification instruction for controlling the next action of the position detection module according to the input instruction, sends the identification instruction to the position detection module, and controls the position detection module to perform the next action.

In step 110, the position detection module detects the indication operation input by the pen indicator according to the identification instruction.

In a specific process, the position detection module receives and analyzes the identification command sent by the controller, so as to detect the indication operation about the position indication input by the pen indicator.

And step 111, the position detection module generates handwriting information according to the indication operation and sends the handwriting information to the controller.

In a specific process, the position detection module generates handwriting information according to the detected result and sends the handwriting information to the controller.

And 112, generating display information by the controller according to the handwriting information, and sending the display information to the display.

In a specific process, the controller receives and analyzes the handwriting information sent by the position detection module, generates display information according to the handwriting information, and sends the display information to the display for displaying.

And 113, the display performs corresponding display operation on the display information according to the specific display instruction.

In a specific process, the display receives the specific display instruction and the display information sent by the controller, analyzes the specific display instruction, and identifies the specific operation intention of the pen indicator, so that the display information is correspondingly displayed according to the specific display instruction.

In detail, when the display analyzes that the specific display instruction is generated by the deleting operation signal, the display carries out deleting operation on the display screen on the display information input by the pen indicator; when the display analyzes that the specific display instruction is generated by the selection operation signal, the display performs selection operation on the display information input by the pen indicator and performs operation according to the next action of the pen indicator; when the display analyzes that the specific display instruction is generated by the handwriting input operation signal, the display performs display operation on the display information input by the pen indicator; when the display analyzes that the specific display instruction is generated by the default operation signal, the display performs the default operation on the display information input by the pen pointer.

When the number of times of pressing is not one, the process proceeds from step 105 to step 114.

In step 114, the controller determines whether the number of times of pressing is two.

In a specific process, when the controller determines that the number of times of pressing is not one, it is further required to detect whether the number of times of pressing of the function key of the pen pointer is two.

If the number of times of pressing is two, go to step 115; if the number of times of pressing is not two, step 116 is entered.

And step 115, the controller generates a selection operation signal, generates a specific display instruction according to the selection operation signal and sends the specific display instruction to the display.

In a specific process, when the pressed times are two, the operation intention of the user is a selection operation, so that the controller generates a selection operation signal, generates a specific display instruction according to the selection operation signal and sends the specific display instruction to the display.

After step 115 is executed, step 108 is entered for the next operation.

When the number of times of pressing is not two, the process proceeds from step 114 to step 116.

And step 116, the controller generates a default operation signal, generates a specific display instruction according to the default operation signal and sends the specific display instruction to the display.

In a specific process, when the number of times of pressing exceeds two times, the user may operate incorrectly, or the user may want to cancel the function selection, at this time, the controller determines that the operation intention of the user is a default operation, generates a default operation signal, and generates a specific display instruction according to the default operation signal to send to the display.

After the step 116 is executed, the step 108 is entered, and the next operation is entered.

When the pressed time period is not greater than the time threshold, the process proceeds from step 107 to step 117.

And step 117, the controller generates a handwriting input operation signal, generates a specific display instruction according to the handwriting input operation signal and sends the specific display instruction to the display.

In a specific process, when the pressing times are one and the pressing duration is not more than the time threshold, the controller judges that the use intention of the user is the handwriting input operation, and then the controller generates a handwriting input operation signal, generates a specific display instruction according to the handwriting input operation signal and sends the specific display instruction to the display.

After step 117 is executed, step 108 is also entered, and the next operation is entered.

According to the input operation method provided by the embodiment of the invention, the function selection of a user is judged according to the length of the pressing time and the pressing times within a certain time, and when the function key is pressed once within a certain time and the pressing time exceeds a preset time threshold, the electromagnetic pen performs erasing operation; when the function key is pressed once within a certain time and the pressing time does not exceed a preset time threshold, the electromagnetic pen performs handwriting input operation; when the electromagnetic pen is pressed twice within a certain time, the electromagnetic pen performs selection operation; when the number of pressing times exceeds two times within a certain time, the electromagnetic pen performs default operation, and the default operation can be set according to the use habit of the user, for example, the default operation is set as handwriting input operation. Meanwhile, the function keys do not need to be switched back and forth, the probability of function selection errors is reduced, and the operation time is shortened, so that the use of a user is facilitated.
