Urban Encounters is our imagination of the future of interactive surfaces within our 5x5x5 site. The crosswalk "island" we chose at the corner of Shattuck and Center in downtown Berkeley promotes an interesting combination of isolation, stuck-ness and loneliness. To bring out these themes into the physical world, we decided to modify existing objects to support traditionally web-only interactions. The two we chose are missed connections, which are the moments where you feel a connection to someone but cannot stop to acknowledge it, and casual encounters, which are the personal ads you often hear about posted on sites like Craigslist. By molding these interactions and inputs/outputs into the objects of the site, we hope to show how one day, anything will be able to be transformed into a computing interface.
- Median strip of crosswalk on Center Street across Shattuck Ave.
- East of Downtown Berkeley BART station
- One block west of University of California campus
- Surrounded by restaurants, stores, company buildings
- An estimated one million pedestrians pass between BART plaza and University of California campus
- Over 18,000 people pass through BART plaza daily
- Downtown Berkeley Association in coordination with City planted decorative native grasses on median strip
- BART station main entrance rotunda
- BART station plaza
- Art sculpture on median strip
- "Earth Song" by Pho Shu Want, native of China and Berkeley resident
- Installed on January 2003
- Deep red, slender, painted steel sculpture resembling tuning fork
- Approximately 42 feet high with 14 inch wide base
- Steel bell suspended around 3 feet above ground to stimulate interaction from passerby
- Designed to tune to the oscillating frequency of the Earth, a low frequency outside of audible human range
- Project of Berkeley Civics Arts Program
- Berkeley has received over $2 million to transform BART plaza and station
- Rotunda landmark will be redesigned to look more transparent
- BART plaza to be redesigned to invite more activity with dining area and seating
- Construction scheduled to start in spring 2015

Step 1: iPad App / Missed Connections
Create an iOS project and replace the default files with their corresponding files uploaded to Hackster. Add the skpsmtpmessage library from https://github.com/jetseven/skpsmtpmessage) (if using ARC: http://stackoverflow.com/questions/9551048/ios5-arc-errors-skpsmtpmessage). Follow the steps at http://dragonmobile.nuancemobiledeveloper.com/public/Help/DragonMobileSDKReference_iOS/Introduction.html to add the Dragon SDK. Upload code onto ipad. Attach to pole via velcro.
Step 2: Casual Encounters Form Factor
Laser cut two pieces of 1/16" plexi according to the cut file provided (one is for the Capacitive Sensor and one is for the LCD screen)
Cut out a circle of stretch jersey 1" larger than the diameter of the pole you plan to attach you device to.
Cut three rectangles. Two the same dimension as your plexi pieces and 1 very small for the aluminum foil. Make sure to leave the extra fabric attached so that you have room to hem the edge.
Hem the edge of your three rectangles using a sewing machine and sew a peice of elastic around the bottom. Make sure to use a zig zag stitch and stretch out the fabric and elastic as you sew them together (otherwise it will not stretch).
Stitch the plexi pieces into the device and attach the LCD and capacitive sensor.
Wire it up and you're ready to install.
Step 3: Casual Encounters Code
Import the CapacitiveSensor library from http://playground.arduino.cc/Main/CapacitiveSensor?from=Main.CapSense.
Upload the arduino code provided on hackster for both the pole attachment device and the crosswalk sensor.
Step 4: Casual Encounters Electronics
Configure Xbee radios to communicate (http://www.hughesy.net/wp/arduino/new-easier-xbee-for-mac-lion-os-x-10-7-with-arduino/).
Assemble electronics according to the fritzing diagrams.
- Adjust capacitive sensor analogRead threshold and/or resistors in circuit such that touch is detected. See http://playground.arduino.cc/Main/CapacitiveSensor for more info on how to set this up.
- Use long wires when connecting the photo-resistor so that it may be placed inside the crosswalk signal object.
- Adjust potentiometer to achieve the desired contrast in the lcd screen.
- Adjust photo-resistor analogRead threshold and/or resistor in circuit such that light and dark are detected reliably.
Step 5: Casual Encounters Form Factor 2 (Crosswalk Sensor)
Laser cut the box parts from the illustrator file provided on hackster.
Assemble the box around the electronics, with the photo-resistor going through the circular hole and the power switch going through the square.
Use your preferred type of adhesive to hold the box together (tape, hot glue, etc.)
