Since technological devices become smaller and our devices are more fused with our bodies, the logical next step is that technology will be placeable on our skin. In this thesis the design process towards a useful application of an interface on the skin is described. To get towards this design, several methods are used in the process. To shape the design challenge, a VIP inspired method is used, which provides a clear design goal and domain. For further developing the design, a user-centered approach is used, where the use of small prototypes helps improve the design. This resulted in a tattoo-like interface on the skin, which enables the user to have more unexpected interactions with others around him. This has been designed as a counter product towards the trend of people turning towards their devices in public situations. This tattoo offers a way of increasing real social interaction, and therefore decreases the social need of interaction through our smart devices. The design can be customly build up to fit the corresponding context, which makes it applicable in many social situations where people might have the need for more social interactions.
