You can use
your finger to interact with the projected screen, just as you
would use an interactive pen. You can use either a pen or your
finger, or use both at the same time.
When performing touch operations with your finger, you
can use up to six fingers (depending on the interactive mode,
operating system, and connection type).
Note: A Touch
Unit is optional for the BrightLink 1480Fi+
and must be installed for finger touch operation.
Note: Finger
touch operations may not work correctly with long or artificial
nails, or fingers wearing bandages. If your fingers are too close
together or crossed, or your sleeve or free hand touches the
screen, finger touch may not be recognized. Some operating systems
may not support gestures such as flicks.
