Design a projected decal for a physical place or object. Your response could be a time-based display of graphics or video specifically composed to illuminate something other than a blank projection screen. Your imagery might relate to (and elicit new meanings from) otherwise banal architectural features in a wall, such as a power outlet, doorknob, water spigot, elevator buttons, or window frame. You might design a projection for a specific object, or, if you are able, for a dynamic site such as a vehicle or a performer's body.
Sketch some poetic or playful concepts for imagery that relates to the geometric, structural, historical, or political features of your site. Create your concept in code, and project your imagery onto your site or object, taking special care to document it. If your design requires precise alignment between virtual and physical spaces, you'll need a tool for projector calibration and keystone correction. Consider libraries like Keystone (for Processing), ofxWarp (for openFrameworks), Cinder-Warping (for Cinder), or software like Millumin or TouchDesigner.
A wide range of new meanings awaits when an illuminated virtual layer is superimposed onto the physical world. Projection can operate as a commentary or a critique, an intervention to probe the historical or political dimensions of a building or monument. In other uses, the projection is a site-specific information visualization, revealing the internal structures of places or objects, the activities that occur in relation to them, or the resources required in their operation. In performance contexts, projections have created new opportunities for responsive set designs, shadow-play, and choreographies of “digital costumes”: responsive, projected displays that are tightly coupled to a performer's body and movements. Augmented projections range from spectacular public illusions that make buildings appear to shimmer, to intimate poetic gestures at the scale of the human face.
The key challenge is to create a strongly motivated relationship between real and virtual: between the projected light and the specific person, place, or thing onto which it is projected. Exemplary works accomplish this through a combination of both formal and conceptual engagement with the site. Choices about what to project on, and what to project on it, are made simultaneously.
