\"living01\"<\/a>
\nFor our living architecture course<\/a>, we created an interactive light installation in the elevator of Avery Hall, controllable by anyone with a cell phone and a twitter account. The simplified process includes texting an emotion to twitter from any cellular phone using the #livarch hashtag. That tweet is then picked up by a realtime search<\/a>, fed through our twitterfeed rss<\/a>, then added to our own twitter account<\/a>. For a more detailed explanation, see this previous post on getting multiple twitter users onto one twitter feed<\/a>. That emotion is then directed to our pachube feed<\/a> and sent through processing<\/a> to an arduino microcontroller<\/a> that controls the color and pulsing of the individual leds. The installation non-invasively attaches to the surface of the elevator via magnets. Allowing it to be placed on any metal surface, such as a building exterior, furniture, or a vehicle.<\/p>\n

 <\/div>\n

The lights within the elevator respond to the mood of the user. For instance, if a student texted \u201chappy #livarch\u201d the space within the elevator would begin to slowly pulse with a greenish\/blue hue. However, if another student sent \u201cangry #livarch\u201d the first light will quickly flash a bright red. There are twelve lights total and show the collective mood of the twelve most recent users. <\/p>\n

 <\/div>\n

In this way, the elevator becomes a living representation of the collective mood of the building, but it is also hoped that a feedback loop can be created, a loop that actually influences the mood of those that ride the elevator. The emotion felt in the lobby will be altered by the time you reach the sixth floor. And that new emotion becomes what gets texted back to the elevator.<\/p>\n

 <\/div>\n

Lastly, future installations will be physically located away from the target user. For instance, Avery\u2019s mood will be projected to the elevator in Uris Hall and vice versa. In this manner, we can both create a new form of pen-pal with distant locations, but also hope that our mood, whether angry, sad, happy or nervous, will both manifest itself in a new form of architecture, but also have an effect on the greater world around us.<\/p>\n
