ANTAGONIST APERTURE.

It performs. It provokes. Antagonist Aperture is a shutter that is responsive to sunlight and movement, operating as a sun shading device and a provoking mediator between the individual and their view. The aperture is closed when the sun is bright, yet opens as a person approaches. A field of Apertures produces provoking views by exploiting feedback from the physical movement along the length of the material actuator. During dark hours of the day the aperture is open, yet may close upon the approach of a person to hide undesirable views or to provoke engagement with the boundary of the building. In this way, walls become active participants – antagonists – in the experience of its users.

So why is responsive kinetic architecture important? Responsive kinetic architecture can mediate between multiple inputs and outputs. In our case it allows the aperture to act as both a window and sunshade without reducing the quality of each performance. Responsive kinetic architecture also allows performance in unexpected and engaging ways by provoking its user or drawing certain views/sequence of views that allow for a designed relationship between interior and exterior.

4a. Fanning Aperture Animation: This output prototype device was conceived on the notion that a small (yet strong) force was needed to open and close a shading component (note two notches at right bottom). This triangle shaped cell with a fan-like aperture didn't perform as expected due to several factors of material (it wasn't smooth enough to move freely and design (the fans didn't follow each other when opening). The animation details the intended output. We are rethinking this approach for future prototype designs.

4b.
Air Diffuser Prototype: This pre-fabricated unit found at the hardware store is shown here
to demonstrate potentials for off the shelf components.













4c. Disposable Camera Aperture: currently investigation...this video documents where we are at with activating the camera aperture.

Attempt to focus the PIR motion sensor.

Motion sensor encased within copper pipe with tapered opening. Motion sensor continues to trip, despite our efforts to limit its input. Perhaps it is broken.

We contacted the manufacturer, and they do not make a less sensitive PIR motion sensor.
