“oneHug” is an interactive media installation for public spaces to strengthen the awareness of human beings towards ecological problems. The installation is meant to travel to different cities and countries. Each individual is asked to reflect its own attitudes. “oneHug” combines technology, natural materials and interaction in context of public spaces. It aims for a strong emotional perception of nature by addressing different human senses: the visual sense, the aural sense and the tactile sense.

In the center of the installation is an interactive replica of a tree, which attracts passersby and asks them for one hug. The tree notices the immediate proximity and reacts by an audiovisual response. The moment of amalgamation between the visitor and the tree is photographically conserved in the tree‘s memory. The memory is visualised by a projection and a special LED display in the treetop. The website (www.one-hug.net) is supposed to round up the installation, going from public space into private space and connect the visitors virtually, all images are collected at this place.

Capacitive sensors are hidden inside the tree trunk, which perceive the proximity of the visitors - the interface seems to work invisible. Thus it supports the feeling of magic and transmit the idea of sensitivity and not of physical forces.

The basic idea of this installation is to encourage the visitors to a non everyday activity in order to enable a new experience. This new curiosity should motivate a reflection of their thinking and behaviour. “oneHug” is aimed to guide into a small dream by sound and light to facilitate a moment of joy to the visitors.
