Good Practice use of the E-Pen & E-Wand when presenting/
teaching:
Please note that as the Pro-Vue functions using infrared light, a ‘line-of-sight’
between the E-Pen/E-Wand and the Projector is essential for effective use.
Therefore, good-practice use requires the presenter/teacher to ensure the E-Pen/
E-Wand is used out of any shadow area, which may occur dependent on your
positioning of the projector to screen. Ceiling-mounting the projector, or use of the
E-Wand (as opposed to the E-Pen) in portable/temporary applications, will
significantly reduce the possibility of shadow.
Using the E-Wand will all but eliminate any
‘in-shadow’ issues.
With your back to the audience, the
E-Pen is most likely to be in shadow.
Facing side-on to the screen and
your audience will significantly reduce
shadow.
