Imagine you miss nature and for some reason cannot leave your apartment.

With myGreenSpace we can bring the nature to you. We are proposing to use head tracking in combination with a wall-sized display for a rich and immersive experience of nature scenes. MyGreenSpace shows a nature scene, a forest in our video, on one wall of a living room. The perspective adjusts to match the position of the viewer. The viewer will feel as if he/she is in the forest.

The forest also conveys information via ambient sounds or visual overlays. Our forest shows "forest spirits" which represent the number of new emails or friends online. What exactly they stand for is up to the user.

Especially with a large screen there are numerous reasons why you might not want a message or reminder pop-up to clearly display certain information. You might want to be reminded of taking your pills but when other people are present in the room, you might find a reminder specific to healthcare devices stigmatizing. Or you just want to be aware of certain facts, like the number of new emails or how many of your friends are online in your favorite social network. Visual ambient information is always there but you can easily choose to ignore it. Sounds can add another layer of ambient information. A woodpecker, like church bells, can give you a sense of time. Or a nightingale can inform you of a certain event. For somebody who doesn‘t know, these sounds will blend into the subtle background noise of the forest, like the twittering of other birds or the sound of the wind in the leaves.

Large urban displays move into sight of our everyday city landscape more and more; they are not limited anymore to the public places of metropolises like New York or Tokyo. With the rapid advances in display technology in terms of size and costs, displays are gaining increased presence in everyday life and in all kinds of environments, leading to the coined term of "ambient displays." To simulate such future display technology like OLED or eInk we have constructed a display wall using rear projection with 6 projectors.

We use the wiiRemote of the Nintendo Wii gaming console as a low-budget head tracking solution. In this field, too, we can expect rapid changes in terms of availability and costs of intuitive head tracking solutions. Microsoft‘s XBox extension kinect (available at the end of 2010), for example, features full-body tracking without the need for any markers. This will make basic head tracking widely available.

MyGreenSpace can become an element of life style and, in combination with its integration into current phenomena like social networks, we consider it to be a desirable product.
