Twine, one of the first Kickstarter projects dealing with specific hardware to connect sensors and aktuators with the Internet, is starting to ship the first bundles these days. For around $100 you can buy a Twine box, that is shown above, that offers WLAN and a multitude of different sensors to check the status of your house or any other real world object you can think of. It runs on two batteries that should offer enough energy to keep Twine up for more than two month.

Another interesting feature is the Web interface Twine offers for specifying event condition action rules for reacting on user defined situations, without programming. The Web interface and ECA rules look quite similar to Microsoft’s On{X} Android App, which we discussed some month ago.

Analyzing and Classifying Personality Traits with Smartphones

Gokul Chittaranjan and his team, including members from Nokia, published an interesting work which introduces the investigation of the relationship between behavioral characteristics derived from rich smartphone data and self-reported personality traits. They used data stems from smartphones of a set of 83 individuals collected over a continuous period of 8 months. The analysis showed that aggregated features obtained from smartphone usage data can be indicators of the Big-Five personality traits. They also developed an automatic method to infer the personality type of a user based on cellphone usage using supervised learning. Surprisingly, their method performs signi cantly above chance and up to 75.9% accuracy.
This seems to be one of the first studies that analysis and classifies the personality characteristics by using smartphone data!

And they won the Pervasive2011 conference best paper award, congratulation guys!
