rojection techniques have been widely used in
Expo '70. Obviously influenced by their flourishing popularity in the last exposition in Montreal,
designers have made projection the major ingredient of many displays. Given the difficulty of efficient mass communication in such a large exhibition, projection technique, which utilizes sight and
sound completely, is clearly a very efficacious medium of mass communication and display.
The exhibitions using projection technique can be
divided roughly into two groups. The first group is
composed of those projections that are adapted to
the flow of the display, allowing people to move
from one place to the next without pause. People
are led into a passageway on a conveyer, which
carries them past various displays along the way.
The second category, on the other hand, are those
projections that take the form of a conventional
film show. These shows may employ some new
schemes of projection or introduce new concepts
of cinematography, although they are basically an
obsolete means of display.
In the first group, the Dutch and Mitsubishi pavilions have quite brilliant exploitations of the pro-

jection technique. In the Dutch Pavilion, numerous
slides and film projections are used effectively in
the exhibition of "nature and the people." The
building is a complex construction that provides
many walls and corners for projection, but its concept and execution are rather orthodox.
The Mitsubishi Pavilion, on the contrary, is more
ambitious. As spectators enter the pavilion, they
are first taken into a room entitled "Four Seasons
in Japan." There, a series of paneled pictures on
the walls shows the beauty and simplicity of
nature. Then, as the spectator steps onto a conveyer (the "Travator"), he is brought into the middle of a violent storm-the chaos of Genesis. This
is the first of two demonstrations of the "Horizontal Mirror Screen" devised by Mitsubishi. As the
Travator carries spectators at the speed of 50 feet
per minute into the center of the room, dualmontaged films of storm are projected on the sidewall screens. Then, the anomalous reflections cast
on the ceiling, floor, and front and rear walls
create a striking world of illusion. This totally new
experience astonishes the senses. A second demonstration uses the same technique: the Travator runs
