A couple of weeks ago I posted the concept of the Twettle, a Wi-Fi enabled kettle which automatically updates Twitter once it’s boiled. One of the things that influenced the project is my belief that we are are fast approaching automation of our status updates on Twitter and Facebook.

You can’t deny that there are millions of people who love telling friends and followers every single detail of their life no matter how trivial or personal. Services like Blippy which show online purchases in your news feed or gadgets like the IBM TV remote that tells your Twitter followers what you’re watching, are going to pop up more and more.

Now what if that automation could get as personal as your emotions?

Sola is a project by Nobu Nakaguchi, an interaction designer ITP Grad Student based in New York. It explores how communication is impacted when contextual emotions are available for everyone to see.

The device that does the work is wearable sensor which captures heart rate, temperature and skin response. This data is then matched to one of eight primary emotions – joy, trust, fear, surprise, sadness, disgust, anger and anticipation.

The emotion is then broadcast through a mobile to social networks like Twitter, Facebook and even blogs. Nobu has also set his Twitter profile picture to change based on his current emotion.

It’s a great idea, similar to the to the ‘Sixth Sense‘ concept showcased at TED.

How long before the capabilities of Sola are in our mobile phones? This offers a whole new way of thinking around marketing. The industry is always claiming that mobile offers the best channel for advertising because of its targeting possibilities, knowing where you are,  what you want and when you want it.

If sensors are measuring your body’s responses, then it doesn’t seem too far fetched that they could easily find out whether you’re thirsty and send you an offer for a bottle of Sprite as you walk past Tescos. Tired? Here, have some Red Bull. Enjoying a movie at the cinema? Recommendations for similar films get sent to your phone.
