Visualisers and the Important Role They Play in Education(January 10, 2012)
MANCHESTER, UNITED KINGDOM -- (Marketwire) -- 01/10/12 -- JP UK is a major player in the educational supplies sector. One of our most popular products is called a visualiser; a piece of electronic equipment commonly used in modern classrooms to encourage interaction and engagement.
A visualiser is a specialised video camera which works by projecting an image of any item placed under the visualisers lens onto an interactive whiteboard, which is centrally located within a classroom or other teaching environment.
Visualisers can also connect to a computer via a USB connection to display the contents of the desktop; videos, slideshows, Power Point presentations, Word documents and websites (if an internet connection is available) can all easily be displayed onto a whiteboard.
This makes it extremely easy for everybody in attendance to see the same thing at the same time.
Teachers may choose to explain a project or assignment by placing an exercise book onto the base of the visualiser and displaying its contents on the central whiteboard, referencing the important sections of the document whilst maintaining eye contact with the students.
Visualisers can be used to display just about anything that is big or small enough to fit onto the base or under the lens (not all visualisers have a base); maps, objects, documents. This makes for a much more interesting lesson than copying notes from a blackboard.
An important factor to consider when researching for the purchase of a visualiser is the "maximum shooting area". This term relates to the size of the content a visualiser can show at any one time. For instance, the Samsung SDP-860 visualiser, which is currently JP-UK's best seller, can easily display an A3 sheet of paper in landscape position. Other visualisers on the market can only show A4 documents in portrait. This has a major impact on usability.
Some visualisers have a fixed camera, others allow for more flexible use and have a camera that can be tilted or rotated, raised or lowered. And just like the standard digital camera market, the quality of the camera inside a visualiser is defined in megapixels. Generally, more megapixels equal better quality images.
Because a visualiser is essentially a digital camera they almost always have the ability to zoom in on the subject. Typically, there are two types of zoom available; optical zoom and digital zoom. Optical zoom generally produces a better quality image; as the lens closes in on the subject the resolution stays the same. Digital zoom can result in grainy and pixelated images as it takes an existing part of the image and expands upon it, thus reducing the overall resolution.
The visualiser has revolutionised the classroom and quickly become a must have item. Teachers' have spoken about how they help to make lessons more engaging and encourage interaction between pupils' and teachers'. They brighten up lessons and easily enable the use of computers and other learning tools.
