There is a need for a method that can assist the treatment of a patient by the functional advantages of a computer to sustain the patient's routine work, brain-computer interface (BCI) and a magnetic wireless tongue-computer interface-Tongue Drive System (TDS). The BCI is used for communicating control command output by a brain, and other nerves are not depended on in the output process. BCI systems usually require complex devices implanted in the scalp or brain to acquire electroencephalogram signals, and then use correlation algorithms to perform feature extraction and conversion of the signals to determine the intention of a user and convert the intention into specific computer control commands. Finally, the command is input into the computer, and the computer operates according to the intention of the user. TDS is a tracking agent formed by implanting, puncturing or tissue-adhering a small permanent magnet to the tongue of a patient, collecting magnetic signals by a sensor to track the motion trajectory of the tongue, and finally outputting the signals to a computer device for processing. However, both of these methods are not widely used in daily life and the expensive system price is unacceptable to many patients.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, a tongue and tooth drive interaction method includes:
establishing an instruction library;
triggering signals of a nipple-like sensor carrier placed in an oral cavity through tongue and/or teeth, wherein the triggering types comprise tongue touch actions, tongue touch positions, tongue touch action times, tongue touch force, tongue touch time, tooth occlusion actions, tooth occlusion force, tooth occlusion action times, tooth occlusion time and tooth occlusion positions;
receiving a signal generated after triggering, and forming a trigger type set comprising a plurality of trigger types according to the received signal;
matching the trigger type set with corresponding instructions in an instruction library;
if the matching is successful;
and transmitting the command to an actuator, and executing the command by an operating device docked by the actuator.
The instruction is a combination of one instruction and one or more trigger types in a set time period. Depending on the meaning of the desired expression to be accomplished by the combination of types, for example:
the method can be divided into three levels of instructions according to the degree required by a user, wherein the first level operation is an emergency function: if rescue and assistance are needed, a primary alarm is issued to alert medical and nursing staff once the command is triggered. Secondary operations are requirements in daily life such as: the upper level of the equal-level operation can send out a second-level alarm according to different contents to inform nursing staff, such as 'eating', 'drinking', 'turning over', 'toileting', 'sputum excretion' and the like. The three-level operation is that the user performs some non-urgent but more complex operations, such as playing music, assisting communication, operating a personal computer or a smart phone, operating an intelligent wheelchair and the like, and the three-level operation requires the user to complete the operations together with the intelligent equipment by means of an upper computer program, and at the moment, the upper computer does not give an alarm. The actions of different levels can be completed by corresponding to different tongue and tooth matching modes, and generally, the actions are from difficult to easy to correspond to the operation levels from low to high (from three levels to one level). The operation of the three levels can be adjusted and divided according to the default recommendation of the system and the self-based condition and will of the user. Tongue and tooth fit can be operated in several ways: 1. the tongue touches a certain position of the bottom of the nipple alone, and the bottom of the nipple can be divided into different functional areas according to different positions and force according to the requirements of users. The action triggers three-stage operation, and when the tongue touches different areas of the bottom of the nipple, different commands are triggered. And transmitting the commands to the upper computer through the signal transmission part, and finally processing by the upper computer. The number of functions and the specific functions of the bottom functional area need to be customized according to the selection of a user. 2. The tongue is stirred and slightly pushed inwards in multiple directions such as up, down, left and right independently, and the system defaults to trigger secondary operation due to the fact that operation is simple. 3. The nipple is occluded by using teeth, and the action can be divided into a plurality of functions according to the requirements of users according to different occlusion times, occlusion force and occlusion time. Such as using a short snap to simulate a single click in computer operation, two consecutive short snaps to simulate a double click, etc. But by default the system will engage the nipple head for more than 1s triggering a level one operation, which is most easily done when the patient is in danger and is difficult to miss in everyday use. 4. Biting the nipple and shaking the head, which is a complex activity and requires the user to be conscious. The action is matched with the completion of three-level operation so as to complete the use of unnecessary but more advanced functions such as cursor movement, intelligent wheelchair movement control and the like. 5. The tongue cooperates with the teeth, and this and other actions can be customized to the user to accomplish their desired task. The actions, operation hierarchies and specific operations listed above are only one possible configuration, and the specific actions, hierarchies and operations can be selected or customized by the user for new functions.
In order to prevent the false judgment after the generation of the invalid signal of the user, the signal which is judged to exceed the set threshold value according to the size of the tongue touch force or the tooth occlusion force before the trigger type set is matched with the corresponding instruction in the instruction library is taken as the valid signal to be carried out in the next step, otherwise, the valid signal is taken as the invalid signal.
Referring to fig. 3, the pacifier-like sensor carrier includes a tongue contact region 2 composed of a plurality of functional regions and a tooth occlusion region 1 included in the tongue contact region and judged as tongue contact or tooth occlusion according to a position combining force. Each functional area is at least provided with one sensor, the sensors are coded according to the functional area where the sensors are located, and the tongue touch position is judged according to the codes of the sensors corresponding to the information.
The docked operating device is an intelligent auxiliary device comprising a computer, a smart phone, a tablet and an intelligent wheelchair.
And establishing the instruction library comprises generating a secondary instruction library from the total instruction library according to the operating equipment docked by the actuator, and triggering the type set to be matched with the secondary instruction library for instructions so as to adapt to different operating equipment.
Referring to fig. 2, the present invention provides a tongue and tooth drive interaction system comprising:
an instruction unit having an instruction library for performing interaction;
the acquisition unit is used for acquiring signals generated after signals are triggered on a nipple-like sensor carrier placed in an oral cavity through tongue and/or teeth, the nipple-like sensor carrier comprises a tongue touch area and a tooth occlusion area which are formed by a plurality of functional areas, the tooth occlusion area is contained in the tongue touch area and is judged to be tongue touch or tooth occlusion according to position combination force, and the triggering type comprises tongue touch action, tongue touch position, tongue touch action times, tongue touch force, tongue touch time, tooth occlusion action, tooth occlusion force, tooth occlusion action times, tooth occlusion time and tooth occlusion position;
a processing unit forming a trigger type set including a plurality of trigger types from the received signal;
the matching unit is used for matching the trigger type set with the corresponding instruction in the instruction library;
the execution unit is used for matching the matching unit successfully; and transmitting the command to an actuator, and executing the command by an operating device docked by the actuator.
And the judging unit is used for judging a signal exceeding a set threshold value as an effective signal to carry out the next step according to the size of tongue touch force or tooth occlusion force before the trigger type set is matched with the corresponding instruction in the instruction library, and otherwise, the signal is used as an ineffective signal.
The above units are realized by a server or a computer as an upper computer, the signal transmission part can be realized in a wireless mode, and the sensing equipment has the advantage of large internal space, so that the control module, the transmission module and the battery can be arranged in the sensing equipment.
The upper computer program part is used for realizing various functions of user operation, and can provide a function module list for a user firstly, so that the user can select the required function module and then add the function module into the system. Meanwhile, the corresponding functional modules can be adjusted according to the requirements of users in different periods. The function module of the upper computer program is divided into a basic function module and an advanced function module. The basic function module corresponds to the users with relatively critical illness states mainly by the primary operation and the secondary operation, and is used for disease monitoring or expressing daily requirements. The user is required to trigger by himself, and after triggering, the system informs the nursing staff or medical staff to help the patient. The function in the "advanced function module" is oriented to some users whose disease conditions are controlled and desire to perform other activities, and the module corresponds to the above three-level operation. The system can be butted with different types of upper computers according to the requirements of users, not only can use a common computer, but also can be butted with other equipment such as a smart phone, a smart wheelchair and the like.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
