The EAT Research centre collaboration in the 1970 Osaka World Exhibition.

The creation of research centres such as the EAT (Experiments in Art and Technology, 1966) encouraged interdisciplinary collaboration between art and science. The involvement of technology companies like Siemens, HP, IBM, or Philips, provided technical and economic support for the development of new specialised optical, sound and data systems related to spatial and perceptive transformation. This collaboration was fundamental in exploring strategies between aesthetics and technology to handle multi-dimensional spaces, which led to experimental immersive spatial proposals performed in World Exhibitions pavilions.
The pavilions created for the Osaka World Exhibition (1970) illustrate the multidisciplinary nature of these collaborations. The interventions performed in the Fuji group, Pepsi Cola group, the US pavilion or the Theatre of total Movement of Jacques Polieri were characterised by technical solutions and multimedia presentations. The audience was located in the middle of the scene, and the dynamic arrangement of light and sound established a not linear spatial narrative conceived for the experience. The architecture was developed, facilitating the inclusion of audiovisual media. Art and technology generated spaces through mechanisms such as light, colour, movement, time, sound, optical devices, images, or the use of different materials, enhancing the spatial qualities to create a unified, interactive space in continuous transformation specially arranged for the observer. The overlapped effects between space and technology achieved an immersive experience, where the use of illusion created a sense of movement to the viewer. The pavilions were a space for perception where the audience could imagine the future and appreciate space in continuous transformation.
