In the field of mobile devices, notifications represent a simple way to inform the users about new emails, messages or incoming phone calls. Besides the display, different output channels can be used to reinforce the hint that a new information has arrived. Simple melodies can be played by speakers or small electric motors can vibrate in different patterns to transport an information. Over time, the users learn how to distinguish these channels and which melody or vibration pattern represents a new email or an incoming phone call. But since 2007, when the company Apple introduced the first smart phone (known as the iPhone), the whole system, how notifications are presented to the user, didn’t change much. The main restriction is, that new notifications are bound to the device to which they arrive. Every time a new notification is posted by an app, the device rings or vibrates and the user has to take it out of his pocket or look for it in his near environment. In some cases, this can be very impractical and annoying when it happens in the middle of a conversation or the user is interrupted while he was working on something. After the user inspected the notification about a new arrived email or message, the new information turns out to be unimportant. If the user had the possibility to be informed about the new notification by another display or device that is near him, he could take a quick look and see if it is something important or not and then return to his previous activity. This thesis presents a notification system that displays user notifications from Android smart phones on different devices that are connected to a central platform. The output devices are simple tablet computers and controllable bulbs, so that they can easily and ambient be integrated in a home environment. We developed different methods to present users their notifications and evaluated them together with the notification system in a user study. In general, we wanted to find out in which situations do users prefer which output devices or methods for which notification types. The gained insights can be used to improve existing notification systems or develop new strategies how notifications could be presented to users.
