Here’s an interesting device, particularly because it offers you the ability to reflectively record and examine your life. Right now it seems to be only limited to movement tracking but I like the idea of using self-surveillance to gain knowledge about oneself. Lifestreaming on the web has already taken a step in that direction.
The simple pedometer has been given a makeover. Fitbit, a startup based in San Francisco, has built a small, unobtrusive sensor that tracks a person’s movement 24 hours a day to produce a record of her steps taken, her calories burned, and even the quality of her sleep. Data is wirelessly uploaded to the Web so that users can monitor their activity and compare it with that of their friends.
