In the first block of the module Interaction Design 1 we had to create an artifact that negates or amplifies a certain distance on campus. Even established students often only know their classmates and would like to meet students from other studies and faculties.
The social aspect is of utter importance in college life. This is where Campus•League comes into play. The service is supposed to connect students playfully by establishing a contest.
A unique ball is placed on every campus arousing the student´s curiosity. The balls resemble classic footbags. Playing with footbags or „Hacky-Sacks“ has come to be a trend over the past years and is especially popular among young people. In our case the balls are much bigger in order to be noticeable and to not get lost easily. It does not matter whether the students play volleyball, football/soccer or any other kind of ball games. The priorities lie within the social aspect and the competition as an appeal. The ball is able to track and send different data of its surroundings. The competition is based on the the individual playtime with each ball.
Hence a score for each campus ist given. Inspired by the Volleyball Wilson known from the movie „Cast Away“ each ball is able to communicate with its environment which encourages potential players even more to play with them. Additionally the current location is transferred in order to inform the followers about the current venue.

Prototype in comparison with a regular foam ball.
Logo family for differentiating between each ball.In order to protect the hardware components from environmental influences they are located within a hardcase shell in the core of the ball. It contains a Arduino Microcontroller which processes each additional module such as the accelerometer. Its purpose is to track the acceleration during the game which enables the differentiation between the ball being thrown and being transported in a backpack.
The GPS-Shield tracks the ball’s location. In order to send it’s current status based on the data required through the aforementioned sensors on social media platforms the micro controller is additionally equipped with a WLAN-Shield. A 9V battery serves as the power source. All components can be accessed through an opening in the hardcase.
Setup of a ball The accumulated data from the balls and different interfaces such as current weather data from OpenWeather are saved in a central database. This database provides the website and social media platforms with contents.
Additionally the database contains predefined quotes which which are sent to each platform after a reconciliation with the (locational) data thus enabling contextual reaction of the balls and there surroundings.
Process of communication between the balls and their environment. 
Website of the league and a ball’s twitter account.The accumulated data is synchronized with the website. Every data concerning the league are retrievable in real time. Additionally the website provides further information about the project and the balls. For enabling interested students to follow the balls’ everyday life each ball possesses own social media accounts.
These accounts serve as multiplicators for increasing the balls’ reputation and enable the players to communicate with each ball and with each other.
