Living in the city one quickly realizes a sense of paradoxical solitude in the presence of so many people. Many of us lead lives of splendid isolation even though we are in such great proximity to others. The NetLight seeks to represent the presence of those physically near as it acts as a networked light switch.

Audience
People who live close to each other physically but separated by the many barriers of modern urban life, for example students in a dorm or professionals in apartments. Later versions will harness the internet for connectivity, allowing greater distances to be bridged.

User Scenario
The switch is fairly passive. A user turns on his/her light and all other networked switches display this presence. Looking at the switch a user can get information about who is home and who is away.

Implementation
Netlight consists of a cut plexi faceplate that houses a switch and an array of LEDs that emit an interesting glow depending on the position of the viewer. An arduino monitors the state of the switch and controls the LEDs, communicating with other NetLights by XBee.

Conclusion
Simple technology can lead to interesting interactions and compelling experiences.
