The NEC U310W isn’t just your typical projector, it is also interactive. With additional purchase of an interactive pen from NEC you open up all kinds of new features. I should note that the interactive pen could be used with multiple projectors not just this projector itself. However, you would lose some key functionality like using the pen to access the menu system of the projector. That feature is specific to this model. Designed for teachers and educators of all types, the interactive pen allows you to control your projector via your IPad, and it allows you to more importantly control your laptop via your IPad. However, that is not all. The pen and IPad application have all kinds of annotation features and drawing tools which is what truly makes this tool a great educational tool. First I will discuss setting up the interactivity then I will walk through some of the features.
