Use digital projectors, either wired or wireless, as a way to share one classroom computer screen at a time. Make use of this type of projector to share presentations with the entire class. Short throw projectors are a newer technology that allows the projector to be installed close to the screen This helps eliminate shadows and light in the eyes of the presenter. Because these projectors create larger pictures from shorter distances, they work well in the classroom.
You can also connect as many as 32 computers and display up to four of them simultaneously with the InFocus IN3900 Interactive Projector. Instructors can interact with the images through the use of a wireless wand.
