Most of us would agree that a classroom or university auditorium is not the most exciting place to be, even for those that enjoy learning. And likewise, most educators would agree that it can be quite difficult to keep students focused for extended periods of time, especially if you are limited to a whiteboard and a few coloured markers. In a world that is filled with sensory stimulants, ranging from marketing efforts to social media, it can be hard to keep your audience engaged throughout a presentation. This is where a visualiser comes into play!

A visualiser, also known as a document camera, is a revolutionary device that allows you to display a real-time image or cast a live video feed onto a monitor or large format display, of anything that is placed underneath the camera lens. A visualiser is typically made up of a movable mechanical arm that has a camera mounted on the end, which allows the user to have a wider range of motion than would typically be afforded by a stationary webcam. This design enables presenters to easily display a variety of objects and documents on a larger screen so that the audience can have a clear view of what is being presented.

Visualisers are becoming an increasingly popular teaching aid as these devices enable teachers to present objects and physical items that can’t be photocopied and distributed to students. A visualiser can be very useful when trying to present material from a book of which you only have one copy. Whether you are trying to present an old newspaper clipping or performing a science experiment, students can easily follow along on a large screen to see exactly what is being presented. These devices are equipped with high-definition cameras and a zoom-in function to ensure that you are able to capture the finest details.

Document cameras range in size but are generally designed to be lightweight and collapsable, making them easily transportable. These devices are also easy to set up and there is no mess of cables to worry about. If you don’t have a computer to connect to, most visualisers can also be connected directly to a projector or LCD screen using the built-in video outputs. Some visualisers have a built-in microphone that allows users to record their session or stream audio without the need for a separate microphone.

AVer visualisers are able to manipulate the displayed image in a number of ways to further improve the clarity of documents or objects and help ensure that all participants are able to engage with the material. Rotate the image, adjust exposure, mirror the feed, zoom in, apply filters and take screenshots to your heart’s content, quickly and easily. Using AVer’s visualiser software, users can cast their webcam- and visualiser feed side by side on a conferencing application. This is especially useful for remote learning as this allows presenters to stream their webcam and visualiser videos to audiences at the same time.
