Unlike Overhead Projectors, Visualisers can display documents, books and many other objects directly through a multimedia projector or Display Screen. Visualisers provide the means for large or small audiences to see details, which would be impossible to see either due to limitation of the human eye, of a subject size, the surroundings or remoteness of the object being viewed.

The Visualisers are a versatile communications tool for applications in corporate training, education, science labs, video conferencing applications.
