Touch area
Touch area Touch area
Environment Condition
The touch module functions with an PointWrite interactive projector for
scalable finger touch functionality, transforming any flat surface into a virtual
interactive whiteboard.
For optimal finger touch quality, follow these guidelines:
1. Close all window curtains.
2. Select a projection area away from direct sunlight to prevent writing
interference.
3. Keep infrared devices, such as: infrared microphones, away from the
front side of the screen to prevent interference.
4. Remove accessories, such as: watches or necklaces, with a reflective
surface to prevent interference.
Preparation for Setup 5
Surface Condition
Optimal finger touch quality is dependent on the selected surface condition.
You can attach the touch module on a wall surface or existing board. It is
important to choose a smooth and flat surface area free of protrusions.
In the event of a projection surface not conducive to finger touch
functionality, select the PointWrite pen as the pointing method for the
classroom.
Selecting a Wall Surface
• Select a wall that is straight and flat, without any protruding objects on it.
• Writing directly on the wall with the pen can damage the wall. Test the
wall surface by writing on it with the dummy pen before you install the
touch module.
Using on the Wall Surface
Consider the following factors when selecting a wall surface to project your
image onto:
• Project on a smooth, semi-gloss painted surface to reduce glare from the
projector, to achieve optimal touch quality and to reduce wear on the pen
nib.
Using on a Dry-erase Board
• Attach a dry-erase board to the wall if you’re projecting on a textured
surface. A dry-erase board is a flat surface that works well with your
interactive projector and allows you to write smoothly in digital ink.
Preparation for Setup6
Measuring the Flatness of the Surface
<2mm <2mm
<2mm <2mm
1. Place a six-foot carpenter’s level horizontally across the projection area
(board).
2. Locate the point on the level furthest away from the projection area.
3. Measure the surface flatness on both sides of the projection area.
• Overall finger touch performance is influenced by the flatness of the
projection surface.
• A flatness variance of 2mm in any direction ensures optimal finger touch
performance.
Preparation for Setup 7
Surface Obstructions
Maintain the projection area clean and free of obstructions. The following are
common obstruction examples:
• Cables or wires that hang into the projected image.
Leave extra space between the cables and the projected image so you can
make image adjustments later.
Preparation for Setup8
