What must I watch out for when using HoloPro™?
HoloPro™ is a rear-projection medium. That means that illumination is from behind and the viewer stands in front of the projection screen. Viewing position and distance: The visibility of HoloPro™ is ±45° horizontally and ±15° vertically. Top view: Side view: Depending on the size of the screen used, there are several possible viewing distances: How high must the HoloPro™ screen be hung up? As a condition of the vertical visibility of ±15°, the centre of the picture on the screen should be positioned at a height of 1.65 m. This corresponds roughly to the average human height. Position of the projector: HoloPro™ is designed so that illumination by the projector takes place at an angle of approx. 36°. It does not matter whether the projection takes place from above or below (the HoloPro™ screen simply has to be turned around accordingly). Projector geometry using a 50″ screen as an example: The larger the illuminated surface is, the further away the projector has to be positioned.
