This handset is a tool for every visitor of exhibitions like a national park or temporary trade fair. You can use it like a navigation system to get information (for example about location, stands). Additionally, it functions as a ticket which you receive at the entrance. Easily it can be placed around the arm and it fits on the shape of your wrist as a bracelet. In a national park you will have the possibility to navigate through the landscape by using the integrated touch display. An aerial registers your position and will help you to find the right way. If you hold the handset to your ear you can get more information about locational details. When finishing the tour, you can keep it by your own or drop it down on the ground, because the material and the printed electronics are bio-degradable and will leave a seed with a plant behind.
