For experiment making, there are a few ways to build a study. Upon them is data science from used BCI. Most of the modern systems allow to fix study results in comfortable representation, for example, as raw EEG data appropriate for any next processing or typically classified by study settings. For example, in PsychoPy you can use a simple projecting interface with a comfortable visual development platform for processing data from different devices.
Experiments and tests usually are based on common popular methods with different levels depending on the target tasks field. This research demonstrates a result of training with Stroop test control, but there are a lot of other strategies which can be combined according to the purpose and the capacity of the system.
A typical organization of a modern intelligent environment equipped with a brain-computer interface passes
through several stages and has its own structure and features. Depending on the scope of application, different
design approaches are used, but the cognitive principles are still stay the basics for intellectual environments
organization [
In educational intelligent systems, the brain-computer interface can be implemented as a complex amplifying component that ensures the optimization of activities in several areas. The first is the braincomputer interface module itself, which adds a new degree of quality to the management of the environment and the operation of information. The second is a mandatory module of training own skills, which helps to realize the skills of mental management in a smart environment and expands cognitive competencies (soft skills). The third is specially focused on a specific application. It is also possible to expand efficiency of the system with the type of hyperscanning, brain-to-brain interaction through the cognitive network, discussion, and competition or game as an organizational approach.
One of the problems with the implementation of brain-computer interfaces is the long-term development
of user mental management skills and maintaining cognitive capacity. An indicator of readiness is a low level
of brain-computer illiteracy. Good data for activity is a reaction, good health, especially clear neurofeedback
of sufficient power [
Then brain-assisted intellectual environment must be equipped with means as technical as software for the
personal development of BCI-abilities and fit own skills constantly. To achieve these conditions the
organization of the BCI-environment should be embodied in efficient projection. The most successful possible
realization of such an idea is well argument decision with enough efficiency. A working group of users can be
represented as a small functional psychological group. Then for creating the special BCI the patterns for
common tasks and features of interaction must be studied, from which the suitable must be selected and
brought into the samples base, if machine learning is used for system development. This compliance is
regulated with basic standards and recommendations from the distributor of equipment and software [
The value of individual mental activity features factor, especially in international groups, should be considered. To pretend such causes, the program for common training must be successfully embodied into a real system and necessarily provided with its use.
For the efficient design with correct implementation of the cognitive approach for the educational environment, a few necessary principles must be obligatory observed. The first between them is the immersive component of user’s interface. Such condition is necessary to include dual concept as system preset as user's skills provided.
Personal-oriented BCI representation usually has a typical user profile descriptive mode, which can be
described as idiolect. A strong well-trained personal profile will be very efficient in the realization of such
functional patterns as mental command and identification (personal BCI recognition) [
Sure, all profiles can be improved in the testing process with a unique machine learning strategy for achievement of desired aim and level, which must be described at the beginning of design with a clear number of features (competencies) and its quality indicators (represented as Professional Brain view or Cognitive Image).
For small groups (5 persons) we can represent it with "jargon" – proficiency-oriented lexis and own
semantics. Usually, such vocabulary is embodied as a command space built with ordered logic-shaped
semantics of its interactions. Each command is a cognemic formation into some space of operational abilities
globally understood as a space of mental activity with the universal grammar of action execution with trained
free will efforts and general translation method namely EEG with chosen technology of signal reception
(fNIRS, MEG, SSVEP, P300 etc.) for recognized data input into the environment for the next management
realization and interface implementation (Fig. 1) [
This structure helps to achieve successful multitask interaction and is acceptable for real enterprises and educational networks including developers and agile platforms providing improving quality and evolutional stability at the same time.
Target tasks can be differentiated by some levels of activity and studies can include quality and priority accordance monitor also. For example, basic working actions can be noticed by screen-timing control in combination with pression and recall analysis. Mindfulness tasks can include individual research on personal psychological activity features namely real neuromarketing on the neuroplasticity training process.
For an illustration of the described method, we studied individual performance metrics dynamics during neuroplasticity training in the improvised environment using EmotivLABs BCI. For the primary and additional research, we have used EmotivBCI and PRO applications, so, our study includes data from different periods and conditions of activity such as routine, tests, stress situations, training, and so on.
Emotiv methods allow to classify a current mental activity based on EEG analysis and represent its results in a few modes. The constant is neuromanagement performance metrics, which illustrated the dynamical representation of activity during the task solving with a used interval of changes in 5 sec. The resultant norms of the efficient performance, collected by the research of 20 attempts with different exercises and training combinations are 54% value for engagement, 21% - exciting, 35% - focus, 21% - interest, 48% - relaxation, and 20% of stress (Figure 2).
Control tests included attention, decision, workload, and emotional metrics. In improvised situations tested
persons, who will more flexible, show the higher reaction in decision-making process then untrained. All these
results you can find in the Figure 3 graph, based on Stroop test control. As stimuli in this training randomly
colored words are used. Then the accuracy is dependent on correct detection of color confirmed by appropriate
key pressing or by voice input. Possible absolute BCI can include a biosensual device for throat impulses
sensing that allows to read and recognize appropriate lingual activity figures. Also, BCI can be combined with
eye-blinking recognition. These directions should have special research and discussion [
By control cuts: 1 – test introduction attempt, first metrics collection, individual image; 2, 3 – correction of individual metrics, development for training; 4, 5 – fixation of skills, current test; 6 – combining with meditation; 7 – stress situation, spontaneous test; 8-12 next 10 attempts training with the same exercises. 2 All values are demonstrating a rate of workload as a percentage relative to the absolute value of performance. Used indicators based on 5 seconds classified study of EEG data from mental activity during the task solving (means decision-making in case of the test).
The next levels of workload and cognitive organization of efficient network development obviously will include a range of improvements for special tasks and conditions. Research and implementation of hybrid BCI require a separate careful study of software connection for target interests achieving and right system design. Besides, this direction gets closer to the technology of invisible computing and intelligent environments using.
Individuality has a large importance in the development and implementation of cognitive networks based on BCI. The well-trained system must have frequent data collecting and serious processing to provide highquality data representation and clear settings with flexible functionality. The user profile must have a stable training program with regular updates.
The next development of described approach should continue accordingly to the conditions and requirements of chosen environment. To achieve the needed quality and efficiency of the system it is important to remember that a special attention must be paid to the software choice and system design.
The nearest conceptual approach which obviously should be considered is mindfulness training. Such ideology can improve the strategy of tests and increase the efficiency of the system, especially in long-term projects such as life-long studies.
The cognitive approach can be implemented with obligate changes and decisions suitable to chosen network features and its appointment. The optimal number of users for the system may be changed in a combined mode of design when some features are simplified, and the basic system is playing the role of server and moderator administrates the network.
