What are visualisers?
Visualisers are also known as document cameras or visual presenters. They are the new modern version of overhead projectors (OHPs). Visualisers are basically cameras mounted on an arm or gooseneck arm used to show in real time, using a projector, monitor or television, a 2D or 3D object to an audience. They can also easily be connected to computers to capture images and interactive whiteboards for interactive presentations. Their ease of use and versatility makes them a very popular tool in education where they help capture the attention of pupils during lessons. They are also very useful in scientific and technical applications.
