Smart projectors that enable users to interact directly with the images and videos displayed are increasingly being used in commerce and education to make meetings and lessons rich and collaborative, says electronics multinational Epson Europe, Middle East, Africa and Russia Visual Instruments director Hans Dummer. The 3LCD smart projectors can display an image with a diagonal length of up to 2.5 m, which is suitable for most meeting rooms and classrooms. The ultra short-throw projectors are mounted against the display surface, making the display shadow-less, which allows for direct interaction with the display on a surface such as a wall or a desk.
