Interaction Design Story

by Jungho Yeom

Mirrored Message Displays (Simple version of Mirrored Message Wall) are set up at the School of Design and Environment, National University of Singapore. To collect the students’ well wish for the Japan Earthquake and Tsunami, two display, which are used to repeat the department information at each floor in SDE building, are replaced with Mirrored Message Displays.

User can post their wishes via SMS and Twitter (@BurbleBubbles). Posted messages appear both displays and Twitter.

This work is supported by Interactive & Digital Media Institute, National University of Singapore.

Since the Mirrored Message Wall is trying to connect to social media such as Twitter, I currently tried to communicate between Twitter and Processing. It captures the tweet feed from the twitter api and send new tweet data to the api. Actually, operating Twitter on the web-based client server will be more efficient but the Processing is still powerful tool for the interactive media designers since it can communicate with other sensor devices to react immediately to the data.

Start communicate with below steps;

1. Create an application on the Twitter developer
http://dev.twitter.com/apps/new

2. Get your application’s “Consumer key” and “Consumer secret” in Application details and “Access Token” and “Access Token Secret” in MyAccessToken menu of your application setting.
Currently other developers using OAuth for Twitter, since previous methods have some errors.

3. Downloads twitter4j java library
http://twitter4j.org/en/index.html#download
(copy twitter4j-core-2.1.6.jar to Processing sketch folder (sketch_name/code))

4. OAuth login to use Twitter API

Twitter twitter;

String consumerKey = "Your Consumer key";

String consumerSecret = "Your Consumer secret";

String accessToken = "Your Access Token";

String accessTokenSecrect = "Your Access Token Secret";

twitter = new TwitterFactory().getOAuthAuthorizedInstance(consumerKey,consumerSecret, new AccessToken(accessToken,accessTokenSecrect));

5. Processing Code example

twitter.getHomeTimeline(); //call latest 20 tweets posted from you and your firneds
twitter.getUserTimeline(); //call latest 20 tweets posted from you
twitter.getMentions(); //call latest 20 tweets mentioned to your id
twitter.updateStatus(String message); //update your tweet

Since we are trying to merge the real and virtual groups, this is the one of  the methods to feel the presence of physical user in the virtual space. Real-time images are generated from the web-cam  using processing and it appears on pixelated tiles in Second Life . In the previous user test, privacy is one of the main issues what they are concerned. It may help to feel the awareness of physical user without privacy issues in the semi-large groups.

New version of Mirrored Message Wall will be set up for the ArchiFest 2010 and Coop in central library NUS soon.
