Hitachi data projectors are able to function as a mouse using either the USB port or the control port located on the back of the projector.
However, they are not intended to be used as a remote presenter. This means that although you can use the remote as a mouse, you will not be able to change slides in a full screen slide show using powerpoint.
I recommend the
Targus remote presenter for this purpose. This device will function as a mouse, pointing device, and will allow you to change slides in powerpoint. In addition, it's inexpensive, wireless, and small enough to easily fit in your pocket.
