If the walls could listen

Leah Buechley from MIT has been working on a project to create interactive wallpaper that uses low-tech materials to create an amazing display.

What I like about this project is how it utilises technologies such as bluetooth: a technology that I still think is underrated and under used. What if your mobile phone could automatically send a signal to the wallpaper, instructing it to change colour in accordance with your mood?

Throughout the day many people update their Facebook or Twitter statuses with either positive or negative posts discussing how they feel. Automated sentiment analysis already exists, all we would need is a mobile app that calculated your mood by analysing your day’s social network updates.

I’m on the hunt for interactive devices that use Twitter and Facebook in more useful ways. Last year those cats at Poke put together Baker Tweet using Arduino, it would be great to see more work like this next year.
