Social network, such as Facebook or Twitter, are an important factor in the communication between individuals of the so called digital natives generation. More and more often, they are used to exchange short bursts of thoughts are comments as a means of staying connected with each other.
The instant communication enabled by those social networks has however created a form of peer-group pressure to constantly check for updates. For example, has an informal get-together been announced or has somebody requested to become your friend? This emerging pressure can make people return to the computer more often than they want. This is why we find our colleagues regularly looking for new status updates in meetings, or on our parties we see it more often that our friends cannot resist to check their Facebook account.
One solution to this is notifying users when something important happened. Mobile phones as personal, ubiquitous, and always connected devices lend themselves as platform, as they are carried with the user most of the time. This, it is no surprise that our phone now not only notify about incoming short messages, but do the same for Twitter @mentions, Facebook message, or friend requests. However, these notifications may go unnoticed, too. Thus, instead of checking our Facebook & Twitter account, we keep looking at our mobile phone for notification items.
With AmbiTweet, we investigate conveying social network statuses by ambient displays. We use a live wallpaper showing a beautiful blue water.The wallpaper can be connected with a Twitter account and visualizes the level of activity in an ambient way. The higher the level of activity on this Twitter account, the brighter and the more busy the water becomes. This can be perceived even in the periphery of the field of vision. Thus, users can become aware of important activity without the need to focus the eyes on the phone.
Ambient displays, in general, have the advantage that they convey information in a continuous but unobtrusive way. They exploit the fact that the brain can process information pre-attentive, i.e. without generating apparent cognitive load. AmbiTweet therefore allows concentrating on a primary task while remaining aware of the level of activity on a social network account.
