o
If the distance is less than 5 mm in all directions, optimal finger touch performance will
likely be achieved.
o
If the distance is between 5 mm and 10 mm in any direction, good to adequate finger
touch performance will likely be achieved.
o
If the distance is between 10 mm and 15 mm in any direction, it is possible to achieve
adequate finger touch performance. However, there could be issues completing the
installation. A flatter board surface is recommended.
o
If the distance is greater than 15 mm in any direction, select a flatter surface.
Surface obstructions
There should be no objects that protrude into the keep out area between the bottom of the projector
mount and the projected image. Objects in this area should be moved or removed before you use your
interactive projector as they can cause parts of the projected image to lose finger touch function.
