Embodiment 1

[0036] The facial expression assistance system includes a head immobilizer and a biosignal detector. The biosignal detector is attached to the actuator. The biosignal detector and the actuator are connected to the controller. The controller communicates with the manual controller through the built-in remote communication module. The controller and the remote monitoring terminal are wirelessly connected, and the power module supplies power to the system. Among them, the actuators are divided into left actuators and right actuators, and the left actuators and the right actuators are symmetrically distributed; the left and right actuators are equipped with several skin pulling and pushing devices, and for each skin pulling and pushing device in the left actuator The right actuator has a corresponding skin pulling and pushing device corresponding to it; the skin pulling and pushing device is a model design and assembly, and there are pull bars that can be freely increased or decrea...

Embodiment 2

[0039]For the control method of facial expression assistance system, biosignal detectors, manual controllers and remote monitoring terminals can all collect or generate signals and transmit them to the controller; the control strategies of the controller are divided into intelligent control strategies based on bioelectric signals and intelligent control strategies based on bioelectrical signals. The passive control strategy of external control, wherein the intelligent control strategy includes a left-right balance module and a healthy subject model comparison module, and the passive control strategy includes a manual control module and a remote control module.

[0040] The working principle of this embodiment is as follows: the intelligent control strategy based on bioelectrical signals means that the controller receives the biosignals amplified and captured by the biosignal detectors in the left and right actuators corresponding one-to-one, and converts the bioelectrical signal...

Abstract

The invention discloses a facial expression auxiliary system and a control method thereof, and belongs to the technical field of motion recognition and application. The facial expression auxiliary system comprises a head fixator and further comprises a biological signal detector, the biological signal detector is attached to an actuator, the biological signal detector and the actuator are connected with a controller, the controller is in wireless connection with a manual controller and a remote monitoring terminal through a remote communication module arranged in the controller, and a power module supplies power to the system. The biological signal detector, the manual controller and the remote monitoring terminal can collect or generate signals and transmit the signals to the controller; the control strategy of the controller is divided into an intelligent control strategy based on a bio-electricity signal and a passive control strategy based on external control, the intelligent control strategy comprises a left-right balancing module and a healthy subject model comparison module, and the passive control strategy comprises a manual control module and a remote control module. According to the invention, the auxiliary realization of the facial expression of the user and the remote communication control and visualization are realized.

Description

technical field [0001] The invention belongs to the technical field of motion recognition and application, and in particular relates to a facial expression assistance system and a control method thereof. Background technique [0002] Facial paralysis is a disease mainly characterized by motor dysfunction of facial expression muscles. It is mostly manifested as paralysis of facial expression muscles on the diseased side. Patients are often unable to complete the most basic movements such as raising eyebrows, closing eyes, and puffing their mouths. In order to reduce the impact on the normal life of patients, more and more easy-to-operate and highly private methods for determining the degree of facial paralysis have been applied. However, the purpose of the determination method is to determine the degree of facial paralysis of the patient, or to give further diagnostic suggestions and knowledge questions and answers, but it cannot fulfill the needs of the patient's facial expr...
