Pentagon Tiling

In searching for a good geometric system for the tiling of the pillows, we have become very interested in pentagon tiling. This system allows for a great deal of variation in the pattern while using the same shape. While we are not entirely constrained to use only one shape, this will make the fabrication process easier, and allow us to continue to design the overall shape after we start production of the individual pillows.

The definition of pentagon tiling patterns is a rich mathematical subject, with new patterns continuing to be discovered. So far, 15 have been discovered, the most recent in 2015. We are focusing on types 7 and 8, as they produce the most interesting, non-repetitive patterns:

Soft Interface

The interactive aspect of the pavilion has focused around the idea of “soft interface.” We consider this to be a key component of the soft city in general, and will use the pavilion as a chance to try to better define what it means for an interface to be soft. Preliminary schematics for this include the adaptability, plasticity, self-learning, tactility, embeddedness of an interface within a system. Considerations for the soft interface prototype in the pavilion could address sound, sight, text, or touch.

Prof. Sean Ahlquist at the University of Michigan is working on some very relevant research to this idea of soft interface, including his recent project “Social Sensory Surfaces” which:

looks to develop new material technologies as tactile interfaces designed to confront critical challenges of learning and social engagement for children with Autism Spectrum Disorder (ASD)…The project connects expertise and technology in textile structures and CNC knitting, programming of gestural and tactile input devices, and design of haptic and visual interfaces for enhanced musical expression. With textiles, the tactile interface is expanded in scale, from wearables to environments and varied in types of input for human-computer interactions. The textiles are tailored for gradations of touch and pressure sensitive input from large sweeping gestures to fine touch, calibrated to prompt a wide variety of response.

In considering how to implement a tactile system such as this as part of the inflatable system, we are considering two possibilities. The first would be to use barometric pressure sensors inside the inflatable to sense if a given inflatable has been squeezed. Though potentially quite simple to implement, obvious disadvantage of this approach is very low resolution (1 pixel!) and would require the  use of relatively small inflatable pillows. A second approach, which seems to pick up on the approach described in Prof. Ahlquist’s project, would be to employ stretch sensors integrated into the inflatable fabric to register pressing touch across a surface. Conductive rubber cord (from Adafruit) organized in a grid) is one relatively cheap system to achieve this. Here is a link from taobao.

(Inhabitable) Bubbles

Inspired by this recent radiolab episode on bubbles, in particular, David Stein’s “big bubble thing” apparatus. This gets me thinking about the form that the BDW pavilion might take, these could prove useful inspiration. The idea of bubbles inside of bubbles is one direction worth exploring. Mostly just fun, with my friend Nick Hanna’s amazing bubble machine kicking it off:

As well as some impressive bubble artistry:

Spatial Identity (Politics)

This fascinating, and somewhat unsettling study came out last year that illustrates techniques for user profiling based on a relatively small number of geolocated tags:

The underlying implications of this paper radically shifts the conversation on user profiling from a purely relational analytic to one with a distinctly spatial dimension. “You Are Where You Go” as the paper says. Looking at geospatial checkins taken from Weibo users in Beijing and Shanghai, the study had success in predicting demographic profile information such as “gender, age, education background, sexual orientation, marital status, blood type and zodiac sign.” Columbia University students also recently implemented the application for the US and US based geolocation/social media platforms.

How does this change the way we think about identity as a spatial construct in the city and the various (soft) tactics for manipulating our identity the city: camouflage, mimicry, misdirection, jamming, etc.? Is even Banksy safe? What new counter-mapping platforms are needed deploying tactics for amplifying or obscuring one’s geo-digital footprint, not only to foil the impending geospatial tracking capacities of governments, corporations, and other potential adversaries, but also, and more importantly, to open up a more engaged conversation with our (increasingly data-mediated) environment?

In this spirit, here is a great collection of maps and mapping practices that sought to “transgress space”, from the Situationists’ Naked City, to William Bunge’s radical cartography of 1960’s Detroit, to forensic maps of drone strikes or toxic waste spills.
