Motorized Lens The lens mirrow is motorized. One power off it closes over the actual lens that emits the image. The image is produced by shining onto a convex like mirror that then directs the image towards the screen. This how it achieves larges images even though it only inches or a few feet from the screen.
Interactive Pen The interactive pen communicates with your projector. The projector communicates via USB with the laptop. Use it to draw, annotate and as a mouse.
