  3. 3. Primary Research Observations Monon Trail, Broad Ripple, IN, USA Cultural Trail, Downtown Indianapolis, IN, USA Our first-hand observations of four different greenway systems revealed important characteristics of greenways and their users. Our observations supported the claims we had found in our secondary research; greenways are unique public spaces that act as an aesthetic experience themselves. Users of greenways are more likely to engage and interact with each other than they would be in a different environment. 1
  4. 4. Primary Research Observations High Line, New York City, NY, USA Paseo de la Reforma, Mexico City, Mexico Our observations helped us understand certain characteristics of greenways critical to our design to be consistent between four different cities and two countries. We found large public art displays; volunteers taking an inventory of local flora; community improvement efforts such as bike rental; and public education projects. In short, we found greenways were public places the local community engaged with in a more than superficial way. 2
  5. 5. Primary Research Feasibility Test Our design relies on a camera/projector system to share the Let’s Chalk square with the partner city; it was critical for us to figure out if this idea was feasible in the least. We were able to determine that it was possible, but our test showed us a few problems for which we would have to account. We determined the chalking surface ought to be painted white in order to maximize contrast and visibility in the projections. We also realized an awning of some sort would be necessary in order to block direct sunlight on the chalking area. 3
  6. 6. Primary Research We ourselves took the opportunity to play a little...for science! Not only was it fun, but helpful to our design. We discovered that while sidewalk chalk is easy to use, one uses up a single piece rather quickly. A reliable, easily accessed source of chalk will be absolutely necessary to the success of our design. For a pilot test, we left behind some fresh sidewalk chalk pieces in a location on Indiana University’s campus. A couple of days later we found a message someone else had left behind with our chalk. This showed us that sidewalk chalk itself invites use. 4

  8. 8. Design Inspiration Brain Extravaganza (http://www.jbtbrains.org/) http://www.wherethehellismatt.com/ Our sources of design inspiration were critical in helping us decide how to execute and frame our design. One of our main inspirations is the recent Brain Extravaganza! public art project undertaken by Dr. Jill Bolte-Taylor and her colleagues in Bloomington, IN. The Brain Extravaganza! was 22 large, anatomically correct brain sculptures placed around the city of Bloomington, IN in order to raise awareness of brain health. The Brain Extravaganza! was meant to be beautiful, entertaining, educational, and interactive. Another source of inspiration is the “Where the Hell is Matt?” project from Matthew Harding. It is a straightforward idea - he travels the world and films himself doing a rather silly dance with local people. It sounds simple, but for us proved to be a powerful exemplar. Matt demonstrated that even just seeing people from other places can have a strong and lasting impact. This insight lies at the center of the collaborative aspects of our design. 6
  9. 9. Design Inspiration High Line Projector, New York City Sidewalk Chalk Art [2] Centro de Cultura Digital, Mexico City Chalk It Up, Sacramento, CA, USA [1] We also drew inspiration from photos of sidewalk chalk festivals. Many cities hold annual community events during which participants come to play with sidewalk chalk and spend time with other community members. Events like Chalk It Up encourage individuals to come and create their own sidewalk chalk art or contribute to a community sidewalk square. Chalk It Up also brings in local artists to create masterpiece squares for everyone to admire. Our observations showed us a couple of other examples of efforts using similar technologies - outdoor projectors, interactive community art projects, dedicated spaces for play. These served as encouragement for our design as we hashed out the details. 7

  11. 11. Let’s Chalk First Iteration An early imagining of a Let’s Chalk installation An early scenario: John and Stacy have been in a long-distance relationship for the past 6 months. One day, John in New York tells Stacy to go to the Let’s Chalk! installation on a greenway in San Francisco at 5pm. She visits it and sees he’s written a message for her, and she can see him projected onto the sidewalk as well. Touched, she writes him a message in return.

  14. 14. Community Place Opportunity Play The framework that defines the opportunity space our design occupies. Community is constrained by place, and place is shaped by that community. The community and place also determine the form of play members take part in. That play, in turn, shapes both the community and the place. As an example: A group of friends (community) plays in a gymnasium (place). The play (basketball) shapes both the community (now an ad hoc basketball team) and the place (now a basketball court). 12
  15. 15. Mobile App From our extended abstract: “If the Let’s Chalk installation provides the surface interaction of the system, the mobile app provides a more in-depth interaction. Its purpose is to provide sharing and communication options that give more meaning to the interpersonal aspects of the surface interaction. The app also serves a support role by allowing users to report problems with the installation.” Having access to the Let’s Chalk mobile application is not a prerequisite for playing with the installation. It will be advertised with a QR code on a display at the installation. It will also be linked on the Let’s Chalk website for download.

  18. 18. Website While the mobile app is meant to enrich the in-the-moment interaction, the website will most likely be used by those who are either about to visit or have already visited a Let’s Chalk installation. Because of this, we designed our website with three specific goals in mind: we want to afford our users an opportunity to reflect on the experience; inform them about the project - why, what, and where; and encourage them to return to the installation. The main page provides our primary reflection tool - a gallery of the pictures of the shared chalking square, called “The Sidewalk.” The sidewalk would include all of the images captured from the current city partnership. A user could switch to different partnerships sidewalks, or view the sidewalks from past weeks. Also on the home page are ways to share the sidewalk images and information about upcoming partnerships. Click here for an interactive wireframe of the Let’s Chalk website. 16

  20. 20. Usability Testing Our usability tests focused on our mobile application. As a result, we changed wording and layout on the home page and the “Report a Problem” screen. The usability tests were a medium fidelity paper prototype conducted in a “Wizard of Oz” style. 18
