remake them into modern approaches.

We will try to make some adaptation, to apply there some new elements.

That are not only buttons, some specific buttons,change some graphics.

Accordingly we will carry out this modifications in the final laboratory works

in order to make it more convenient for people.

In the fourth laboratory work we will model visibility to which people pay attention,

and what points do people pay attention to most often.

What If, we take this screen,for example,

then we have a panel of buttons

and while I'm telling you something about this part, you don't look at it.

Respectively, your focus is on a central area. These tricks are also calculated for you.

Also there are methods of eye tracking, mouse (mouse-tracking),

and time parameters are explored, calculated ways

(how long we move on the screen, observe, recognize).

We will discuss those methods on our lectures, you will see them.

Well, so that we can somehow connect what we program,

we will need more such methods from mathematical engineering psychology.

There are many such methods,

formulas by which all this calculates for different age groups.

We will discuss this in lectures.

In the end, you will be able to take into account ergonomic shortcomings,

will create prototypes descriptions (2 - 3 laboratory works)

and behavior models (partly 2nd, partly 4th laboratory works).

In a complex, it will give you the chance to write better software products in offices.

In addition, when you formulate requirements,

you always want your program to provide certain functions.

If there is a function, then there is a criterion.

If there is a criterion, you need to select the desired component: button, drop-down menu etc.

The person respond faster to such elements and will control this device or interface faster.

You will also need to do performance evaluations.

Performance evaluations are usually calculated using statistical methods.

Perhaps such statistical methods were explained to you in mathematical analysis or linear algebra.

This is, for example, the arithmetic mean, variance,

median, weighted average, geometric mean, and so on.

These methods are mainly used.

You passed them on other subjects.

Now let's talk about basic concepts and definitions.

Our first question is the basic definitions.

It is worth writing down to remember later on the tests.

So, the most basic definition in Human-Machine Interaction is the interface.

We will look at the interface from a human perspective.

There are also software interfaces where APIs, data packets, electrical signals are transmitted.

Interface (from the eng. Interface - distribution, surface, partition), ie how it is separated from other components on the screen.

This includes research into the various means by which we can organize this interface,

methods, descriptions of rules (how who and with whom will interact to manage objects).

The interface means not only devices but also rules (protocols) of the interaction of these devices.

This is a general definition that says what an interface is in general, and then we will clarify it accordingly.

Intellectualization is what concerns the AI department.

Here comes the concept of the psychological life of a particular person.

If you choose a child, she has little experience, her own psychological reaction.

And if you take an older person, then she has experience in managing old devices.

Therefore, your program should preferably look like one of the old devices on the control buttons.

Then older people will find it easier to adapt.

Then you will be able to change different data a little.

First of all, we must first investigate a particular person: his age, gender, education,

his ability to respond to certain objects, and in general whether he wants to respond to them.

Accordingly, there are many methods of engineering psychology, which count it all in numbers.

In addition, it is necessary to take into account the spiritual component,

because religion has a strong enough impact on human life.

If you write programs for religious institutions,

then their religious canons will have to be followed.

Also, the level of intelligence, the level of understanding are important

and are taken into account when calculating those numbers and formulas,

which then allow us to place buttons on the screen.

Every time you do something, you will definitely have to go through certain stages.

These stages are the application of methods.

In all other subjects, you have always been taught: method, method, method ...

The method is a certain structured set of steps.

For example, there is a method: step 1- do it, step 2- do it, step 3- do it.

If you were able to go through all the steps step by step

you will then be able to build a fairly efficient interaction algorithm
