Description
Technical Field
[0001] The present invention relates to the technical field of attention training, and in particular to an attention allocation training device. Background Art
[0002] When performing various flight missions, pilots need to monitor a large amount of information at the same time, which requires them to have efficient visual attention allocation capabilities. The pilot's attention allocation ability directly affects flight safety. Through effective attention allocation training, the risk of misjudgment and operational errors caused by distracted attention during flight can be reduced.
[0003] After searching, the Chinese patent number CN220340816U discloses an auxiliary training device for recording the attention distribution of flight trainees, including a bottom plate, a base fixedly connected to one side of the top of the bottom plate, a slide groove provided on the base, and a seat provided on the slide groove for supporting the flight trainees; a visual component, which is arranged on the other side of the top of the bottom plate through a multifunctional bracket, and is used to provide visual and sound feedback to the flight trainees; a simulation component, which is arranged on the multifunctional bracket and located between the seat and the visual component, and is used to simulate the flight function for the flight trainees; a detection component, which is arranged corresponding to the simulation component and is worn on the eyes of the flight trainees, and is used to monitor the eye movement trajectory of the flight trainees. This patent is small in size and light in weight, so that pilots can perform eye movements more naturally during the mission, thereby improving the precision and accuracy of the recorded data, and improving the training quality and flight safety of pilots. The Chinese patent number CN220340816U solves the problems of existing simulator equipment, which are high cost and poor scalability. Eye tracker technology mostly uses head-mounted or desktop devices, which are large in size, heavy in weight, not natural and convenient enough, and it is difficult to ensure the natural eye movement state of pilots when performing tasks.
[0004] However, in the actual use of the above-mentioned device, the attention load capacity of different flight trainees varies greatly. It is difficult for the training equipment to carry out personalized training, and it is difficult to adjust and optimize according to the specific needs and skill levels of each trainee, which may lead to unsatisfactory training results. Therefore, it is necessary to propose an attention allocation training device. Summary of the invention

[0034] Among them, x is the output value after the convolution operation;
[0035] Pooling operation: By selecting the average value in the local perception area as the pooling result, the spatial dimension of the feature map is reduced and important feature information is retained;
[0036] Fully connected operation: After multiple convolution and pooling operations, the feature map is expanded into a one-dimensional vector and passed through a fully connected layer for classification or regression tasks. Each neuron in the fully connected layer is connected to all neurons in the previous layer, and the mapping relationship between input and output is established by learning weights and biases.
[0037] Loss function: In the convolutional neural network model, the cross entropy loss function is used to measure the gap between the model's prediction results and the true label;
[0038] Back propagation algorithm: Use the back propagation algorithm to calculate the gradient of the loss function with respect to the model parameters, and use gradient descent to update the model parameters to continuously optimize the performance of the model.
[0039] The first rotating shaft is rotationally connected to the eye detection platform, the third rotating shaft is rotationally connected to the slider, the outside of the eye detection platform is fixedly connected with a fixing rod, and the fixing rod is slidingly connected to the slider.
[0040] A first motor is fixedly installed on the outside of the eye detection platform, and the output end of the first motor is fixedly connected to the threaded rod.
