What is Aspect Ratio?
Aspect ratio is the ratio of the image width to image height. Standard TV 
screens and older laptops are 4:3; HDTV and most DVDs are 16:9; and 
widescreen computers are 16:10. If you are projecting onto a screen, the 
size/shape of the screen will influence the aspect ratio you decide to use. If 
you are projecting onto a blank wall, there are no screen size restrictions. 
What you plan to project will also help you choose between 4:3, 16:9 or 
16:10. Many TV shows are 4:3, while...

LiteBoard™ Wand
The LiteBoard Wand works like a wireless mouse - but one that works in 
midair, not on your desktop. Just hold the wand in your hand, and point it 
at the projected image to point, click and drag. The wand works with all 
your software, just like a regular mouse.

powered on and connected to your computer.

Buttons and Wand Tip
The wands three top buttons are equivalent to the left (labeled L), right 
(labeled R), and middle (labeled M) buttons on a mouse. The wands tip is 
also a button, and its also equivalent to the left mouse button. NOTE: By 
default, the M button changes wand motion between Normal and Draw. 
Normal makes clicking easier, but Draw allows smoother motion. You can 
change the M button to perform other functions, including a standard 
middle button mouse click (see LiteBoard Wand Menu...

moves when you hold down the wand’s tip or the L button on the wand 
(use the R button to click).
