Projection technology in education has changed so much over the last few years and is a far cry from the dusty OHP acetates some of us remember from our school days.
Education venues still need large screen sizes to be able to share content with the whole class. This lends itself more to projector technology rather than flat screen displays due to the lower cost and portability of projectors. Flat screen displays would be incredibly expensive for the same screen size. Projectors can even go super-wide without requiring a huge increase in expenditure allowing more students to work collaboratively at the projection screen/wall.
Optoma has a range of document cameras which allow teaching staff to share passages of text, maps, diagrams and 3D objects with the whole class. Its DC550 has an 8 megapixel camera, 17x optical zoom and 30 frames-per-second video. Teachers can annotate on the image and even capture lessons as video clips to use later.
Interactive projectors foster greater collaboration in a class. Optoma’s 10-point finger-touch interactive technology, seen in its 320 range of ultra short throw projectors, enables several people to work simultaneously on the screen/wall without using a pen. It is easy to draw, annotate, zoom and rotate images, open documents or browse the web without touching a computer.
Education venues need to ensure that downtime through maintenance is minimised. Laser projectors, such as Optoma’s ZU650 projector, have now become a cost-effective option for schools and provide around 20,000 hours of impressive, virtually maintenance-free operation.
