Used as a scanning
backlight, we are ok
if viewer moves up/down
But not left right, because at the bottom, one corner gets no rays
…nor if the viewermoves close because we
rays are always parallel

• People use IT to influence others, so the ideal interface is a link between people
• Aperture diffraction constrains window-like interfaces
• Passive guides have too few degrees of freedom so we need machine vision or active guides
