A visual presenter is a device that helps to thoroughly view any object by placing it in the camera lens.
It is also called a visual presenter by document cameras, visualizer, and digital overhead (
Also known as Document Camera)
It is an information and communication technology demonstration for classroom teaching.
It can be connected directly to a PC or an interactive whiteboard, projector or LCD screen.
It is one of the most suitable demonstration tools for teaching in today's era.
It can show any kind of material. e.
Photos, books or 2D
3D objects and provide high resolution output for video, projector, display and interactive whiteboard or videoconferencing.
There are three types of visual presenters on the market: desktop visual presenter portable visual presenter goose neck visual presenter desktop has a large operating surface area that can be operated without a computer, portable visual presenters are particularly useful for unimpeded maintenance of views between teachers and students.
The goose neck visual demonstrator offers flexibility to connect to a microscope that helps to display small objects into a larger view.
The use of visual presenters of arts and crafts is not limited to catering to specific topics.
Its flexibility allows the device to be used for different purposes.
Therefore, teachers can use this equipment in their respective subjects.
Similarly, in the case of arts and crafts class, if the teacher wants to make a sculpture of a Shell Wind Bell while making the Wind Bell, the teacher wants to drill a small hole in each shell.
By putting your hand under the camera lens, it can be easily displayed to a large number of students.
Students sitting in any corner or place of the classroom will soon see it.
Teachers and students can enjoy the classroom without any interference.
Here, students need to learn about the various devices in the physical laboratory, such as PRISM, lens and mirror.
The visual presenter is able to show a small part of the device. e.
.
It allows us to easily display the small parts of the cursor calipers on the display, namely the outer claw, the sliding strip and the depth probe of the huge shape.
It can help students to easily see images without pushing their eyes.
Another important equipment in the physical laboratory is the kilogramme, which is also known.
The name itself means measuring a small length.
Teachers don't need to worry about showing details to students.
Having a visual presenter helps to easily display small details.
By connecting the head of the visual presenter to the microscope, any microscopic objects, slides, and celestial bodies can also be displayed effortlessly to each student.
For example, Prism.
Size object of solid shape.
When discussing the terms of the Prism correctly.
Sometimes the students say "Madam, we can't understand the concept clearly", which annoys the teacher.
Can you explain it again? Wait a minute;
Teachers have visual presenters, save lectures with audio
Video records of countless queries can be displayed at any time.
Similarly, students can understand the reflection rules of the mirror with more precise focus maps.
Most students encounter problems in the light drawing;
It needs to be practiced several times.
Visual Presenters animate the light map of a concave or convex mirror, making it easier to quickly and correctly understand, enabling them to absorb the concept of a lifetime.
This also helps students to illustrate this in practice.
Similarly, with the help of an animated representation by a visual presenter, the light of the lens can be more effectively understood when it passes by converging or divergent.
Here, teachers can define the concept many times;
Due to the applicability of the recording function, teachers do not need to draw charts over and over again.
Biology lab 3-visual presenters can also be usedD objects, i. e.
Flowers, leaves and specimens.
Students can understand the work of surgical and anatomical tools such as blades, tweezers, surgical knives, tissue punches for anatomical activities and their storage.
By placing these tools under the camera, they are easily known, and a large number of students will see the images of the tools clearly.
Similarly, teachers can easily demonstrate the structure, the atomic bond angle, associated with the chemistry laboratory.
Visual Presenters also help to understand the angle between bonds and their molecular structure --
Linear, triangular plane, four sides, eight sides and triangular pyramid with 3-
D representation and key angle.
In order to understand the molecular structure effectively, the graph representation of the key is used as 2-
Molecular structure is obtained by visual presenter.
A space-filled model or CPR model that displays the atoms in the color scheme in the representation, where the molecules are represented by overlapping spheres that represent the atoms.
If a teacher tries to show it by hand, everyone can't see it clearly.
If you try to use a visual presenter, you can expect a good response from the student side.
The clear picture will give students more clarification by turning the hardest courses into easier ones --out.
When it comes to understanding mathematics, students will encounter difficulties.
For a better understanding of the bidagolas theorem, it can be understood using graphs or models.
By using visual presenters, teachers can make the whole horror course more interesting and easy to understand.
When students learn with the help of charts, they tend to contact more.
In fact, how to apply the mathematical concept in an interesting way makes the concept more practical.
Everyone knows that it takes a lot of time when a teacher makes a chart for some math equations, sometimes it becomes untidy, students are hard to understand, and when the teacher is done, they keep silent.
Due to incorrect graphics, students become hesitant to clear queries. Ready-
The chart or textbook content produced can be placed under the lens of a visual presenter.
It will show each student the correct image in a clear way.
Everything looks interesting and pragmatic in general.
It seems that it gives meaning to the education system in which teachers and students tend to associate with concepts by injecting new ideas.
Visual Presenters have the ability to create interest for students and teachers.
