If finger touch interactivity does not work, try the
following solutions:
- Make sure a Touch Unit is installed correctly and
the cable is properly connected. See your projector's online
Installation Guide for details.
- If the light on the Touch Unit is not on, check the
Touch Unit settings in the
Pen/Touch menu and make sure the Power setting is set to On.
- If you are using a Mac with your projector, make
sure that you installed the Easy Interactive Tools software, and
that you have downloaded and installed the latest Easy Interactive
Driver from the Epson support site.
- Adjust the angle on the Touch Unit. See your
projector's online Installation Guide for
details.
- Make sure
there are no obstacles (such as cables) between the Touch Unit's
laser diffusion ports and the projection surface. If there are any obstacles that are difficult to move, attach
the infrared deflectors to the projection surface. See your
projector's online Installation Guide for
details.
- Remove any
decorative lights from around the projector or projection
surface.
- If you are
having difficulty double-clicking on a Mac, go to the System Preferences menu, select Mouse, Trackpad, or Mouse
& Trackpad, and reduce the Double-click speed.
- Make sure
there is no interference from infrared remote controls, mice, or
infrared microphones.
- Make sure
you have performed pen calibration and finger touch calibration.
Try recalibrating.
- Keep your clothing or parts of your body more than
0.4 inches (1 cm) away from the projection surface.
- If there are people within 4 inches (10 cm) in front
of or around the projection screen or there are any obstacles
causing interference, touch operations may not work properly.
- If touch operation does not work correctly even
after calibration, check the Calibration
Range setting in the Pen/Touch menu. Select Wide if you drag items when touching the
screen or Narrow if mouse
operations do not work smoothly.
