Multimedia Projectors for School and Office: Types, Uses and Features

Multimedia Projectors for School have become an integral part of every educational institute and office. Schools and offices have changed dramatically over the last decade. With the advent of new digital technology, multimedia projectors have found utility in almost every educational and business organization.

Today multimedia projectors find themselves as a centerpiece of every lecture, classroom lesson, training session, conference, seminar, and business meeting. They have helped to transform a conventional educational institute or office by many folds. Today, the teacher no longer has to rely on papers to disseminate information among their students. Similarly, employees don’t need to crowd around a laptop/PC screen to access information.

Brands like Epson, Optoma, Globus Infocom offer a wide range of Multimedia Projectors for School ranging from short throw projectors to long-throw ones. Each one of them speaks of high-quality images, brightness, and low-maintenance operational life. However, each type of projector caters to different sizes and types of room. In this post, you will read in detail about different types of projectors and their uses.

Different Types of Multimedia Projectors

Short Throw Projector

Short Throw Projector, as the name suggests, is perfectly suited for small conference rooms, meeting rooms, classrooms, etc. As the projector is installed very close to the whiteboard or screen, there are no hassles of interfering shadows or glare in the presenter’s eyes. The presenter or teacher can easily demonstrate data on the screen without distracting shadows. Globus Short Throw Projectors are extensively used in our education solution Digital Teaching System. The projector is mounted just above the whiteboard to project images.

Long Throw Projector

Long Throw Projectors usually have long throw distance. The projector is placed at a larger distance from the projector screen as compared to the short throw projectors. Such type of projectors is suitable for large rooms, large hall, exhibition rooms, home theatres, classrooms, auditoriums, etc. With long throw projectors, you have a larger space between the projector and the screen.

Portable (Mini) Projector

Portable projectors are suitable for people who often travel for work. They are also work in the favour of educational institutes who don’t want to designate a particular room for classroom sessions. Portable projectors can be taken out anywhere and lessons/meetings can be delivered without much cable hassles. For example, Globus Gyaan Samvaad is lightweight and easy to carry. It comes with inbuilt speakers for audio output as well as a carry pouch to protect it from damage while traveling. Globus also provides pre-loaded content for multimedia-rich classroom lessons.

Multimedia Projector: A Requisite for Modern Classroom

With the advent of projectors in education, most teachers rely on displaying content and multimedia on a screen. Instead of writing the notes on the blackboard, teachers prefer powerpoint presentations or short videos for communicating course content to the students.

With the help of Multimedia Projectors for School, teachers can display PowerPoint presentations or highly organized notes for the class. This not only saves the valuable time of teachers and students but also avoids crowding near the blackboard. Importantly, students can even ask the teachers to email the slides in case they missed the class due to certain reasons. These notes can be preserved for further studies before the examination.

Secondly, subjects are better understood when students are provided with multimedia like images, videos, infographics support the learning. Teachers can also use the internet by displaying web content on the screen. The limited duration of a class can be utilized better in useful things instead of writing and erasing on the whiteboard. Teachers can prepare notes prior to the class for an easy presentation.

Students can get used to latest technology right from a young age with the help of projectors and interactive boards. Instead of making paper-based project files, they can prepare PowerPoint presentations or videos to display their understanding of the subject. This gradual move towards digital technology in education is also proving to be eco-friendly since there is reduced reliance on papers and print outs.

Important Things to Know About Multimedia Projector

Here are some important aspects to keep in mind while buying a projector. There are many words and jargon used to explain the technical specifications of a projector. It’s important for people to have an in-depth knowledge of these key aspects before picking up a projector.

Resolution and Aspect Ratio

Resolution is the number of distinct pixels in each dimension that can be displayed. It is expressed as the number of columns and rows of pixels creating the display. For example 1280x800 (WXGA). The greater the resolution, the greater will be the detail and sharpness of the image projected on the screen.

Contrast Ratio

The difference between the lightest and the darkest areas of the projected image is known as the contrast ratio of a projector.

Throw Ratio

The projection distance divided by the width of the projected image is called the Throw Ratio of a projector. A smaller throw ratio will provide large projection sizes from a shorter distance.

Keystone Correction

Keystone Correction is a digital image adjustment used to realign the image when projected at an angle to the screen. It enables the projector to display a rectangular image instead of a keystone shape. Some Projectors provide both horizontal and vertical keystone correction.

Globus offers a wide range of Multimedia Projectors for School ranging from ultra-short throw projectors to portable mini projectors. They are extensively used in many schools, colleges, organizations, etc. They are also a key component of the Globus Digital Teaching System.
