When presenting to a class or an auditorium, you may want something to help you move from slide to slide from far distances. Or maybe something that can help focus attention to key words or when you explain parts of a diagram. These objects are usually called pointers. My main focus today would be one equipped with a laser.
The Logitech Wireless Presenter R400 (
link) is an excellent device for this example. With the capability of moving forwards or backwards in presentations, with a nifty laser to help focus the audience. It has two additional features that lets you turn off your screen (for specific software) and start your slide show from the first slide.
Pros: With the latest of Plug & Play USB technology, this device can self-install within mere moments of the USB reciever being attached to the computer. The wireless receiver also lets you move up to 50 feet away from it!
Cons: Unfortunately, the "Begin Slide" button, only works from the beginning of the presentation, and not from the current slide. Also, without the use of the mouse, some presentations may not be able to successfully control videos that were imbedded into the presentation.
