Considerations on E14 Projection

It is evident that both an exterior projection on the corrugated aluminum of E14 and on the model are feasible. In general, I think the projection onto the building itself is more impressive.

Nevertheless, the choice of which path to take and how effective it will be is dependent upon the content and the message. I, personally, still feel as though the message is undefined. We want to celebrate the building, sure, but what is it that we are trying to convey to the sponsors that is specific to E14 and not merely a reiteration of the Lab's mission? Are we thanking the sponsors for their support of the Lab? Are we encouraging sponsors to continue supporting the Lab? Are we trying to point out what our audience of sponsors, not the future residents, have to look forward to in E14? To take the slogan used for E14, "A new home for technological innovation, design, and the arts," by itself does little to guide the performance. With simply that, I don't think we'll arrive at something remarkable. What specifically are we trying to convey? Also, to what degree is this performative?

If we are trying to explain the building, how it will function, and the arrangements of its spaces, then projection onto the model is probably the best route. Projecting onto the entirety of the building, as we can do with the model, we have the potential to highlight the entirety of the building.

Using the model, the piece would feel like an installation. As such, we don't have as strong a sense of narrative continuity and the experience lends itself to interactivity. Of course, an interactive experience is entirely possible with the exterior projection, too, and is perhaps worth exploring.

We had talked about using the model and projecting elsewhere to increase the scale of the experience. One idea I've been mulling over embraces the notion of projection and light. Suppose we consider the model as a lens and what gets projected onto it is distorted or magnified or diffracted into more detailed information as the model "transmits" the light to a surface beyond. Despite my qualms about projecting onto Here-There and that a wall not at full bleed will come across as a trite projection, I've been imagining having the model at the railing in the upper atrium. The E15 face of the model would be facing Here-There across the opening. A projection onto the model would then extend "through" the model onto the wall. Of course, this would be implemented by having one or more projectors mounted to project on the wall with the conceit of the projection emerging from the model. The projected image beyond would be able to extend below the first floor plane and increase the scale of the experience with the model. With appropriate black levels, designs not relying one the shape of the projected frame would help break the impression of merely a projected image. In this setup, instead of projecting onto the model, sponsors could take flashlights, for example, and shine them on the model. A system could track the orientation of the flashlight and project on the wall beyond accordingly, as if the beam of light continued through the building model onto the wall, showing an image of interior spaces or what have you corresponding to the the area of the model illuminated. Multiple users could participate this way.

Projecting onto the western or southern faces of the building itself would require a full-bleed setup to look decent. If the pipe screen is in fact up or partially up near the corrugated aluminum sections by Sponsor Week, this will be more difficult, as the pipe screen overlaps the solid wall. The south façade is a bit more challenging—though interesting—due to the stairwell windows. Those windows are not completely transparent and do reflect some light, so it may be interesting to use this for projection of silhouettes in the windows, but not for any important content. The projection can begin with the silhouettes interacting "behind" the glass and then extend out onto the aluminum surface.

Regardless, the window shapes will need to be treated integrally in the design of the content. Software will need to be developed to register the locations of the windows on-site during setup by computing homographies for each. For either façade, software will be needed for keystone correction, since the projectors in question have only vertical keystoning and we discussed mounting the projectors on their sides. The built-in keystoning is digital, not optical, so the pixel loss is moot. The lens did exhibit barrel distortion at that distance. Whether or not we'll need to compensate for this remains to be seen. Using multiple projectors, we'll need to edge blend by about 20% of the image. That can be done in the display software, as well.
