Interactive light systems create unique opportunities for different kinds of social interactions in public places. This thesis explores movement as the main interaction to discover and create new ways of engaging in social interaction as well as to encourage people of different age groups to come together and participate. To further explore and answer the questions in mind, different field studies such as interviews and user tests were implemented to gather information on how the pedestrian’s thoughts and actions were. The outcome of these field studies showed that there is a slight shyness in the Swedish people and that they need to be encouraged to start socially interacting. Which through the presented prototype and its mechanics worked and allowed the participants to express their thoughts and feelings regarding an interactive light system that could encourage social interaction in public spaces.
