The IW2 transforms most any flat surface – including walls and soft projector screens – into an interactive whiteboard for learning and presentations. And with the convenience of wireless operation – with no Wi-Fi required! – IW2 offers a dynamic new level of multimedia interaction for lessons and presentations. IW2 is made up of three devices: the Interactive Pen, the Sensor Cam, and the Wireless Receiver. The Sensor Cam reads infrared signals emitted by the Pen and sends that information wirelessly to the Receiver, which is plugged into your computer’s USB port. The Pen’s motion – as well as button presses – are translated into cursor movements, mouse clicks, and mouse drags. And because infrared is the same technology used in many wireless mousse, no Wi-Fi is required. IW2 just works! Included IPEVO Annotator software allows you to annotate your image in real time to add emphasis or even play educational games. IW2 is also compatible with many software applications, which you can control just as if you were at the computer. IW2 also works great with any IPEVO document camera so you can interact with real-time video of handwritten notes, 3D objects, and much more. Setup and calibration only take a couple of minutes. Plus, IW2 is ultra-portable and works with a wide variety of projectors – even short-throw and ultra short-throw projectors. You don’t have to worry about throw distance because IW2’s Sensor Cam connects wirelessly to your computer, not your projector. Please note: Computer and projector are not included in the package. You need to have an existing computer and projector to pair with the IW2.
