In our modern world of today, there are a lot of public locations with large open spaces where all people do is wait or pass through. Some examples are train stations, airports and waiting lines at theme parks. Even though people in these locations are surrounded by many other individuals, there is no social interaction and generally a gloomy atmosphere. I. M.O.V.E. is designed to change this. This interactive system based on motion tracking aims to entertain people using projections by motivating them to move around, explore and, most importantly, interact with each other. To begin this project, after defining and analyzing the problem, research was done on the subject of interaction design to discover more about how people could be attracted and encouraged to participate, how to detect people, interactive systems that already existed, the necessary hardware and how to generate fun and attractive graphics. To ensure a fluent development of the project, the development process was established beforehand describing all tools used for collaboration, planning and general organization. Based on the software design, I. M.O.V.E. was divided into three parts. The first part was calibration. Because the circumstances in which this system has to run are very diverse and unpredictable due to, for example, different projector and camera positions, the system has to be calibrated to be able to work properly on a specific location. The next part is people detection which extracts locations from people walking on the scene. The final part is the scene which generates art based on people’s locations and movements. All the possible events in the scene and their details are described in the system design. The system was well tested on different locations and machines. Each individual part was tested using specific methods and many integration tests were done to test the whole system and to optimize it for the final installation. An evaluation was done to describe the quality of the final product which includes a discussion and recommendations.
