Growth – Design of a game using Kinect and physical building blocks

Growth is a two player life-size game that involves moving the whole body and building in 3D space. It uses a Kinect to recognize the building blocks as well as their attributes like colors and their height. This is combined with a projector that screens information such as score and instructions for the players on the play area. Visual feedback is given to the players throughout the game by projecting colors on the pieces of the person in the lead. After the game is finished, the pieces of the winner lights up to give direct feedback on the winner.

The game can be compared to plants battle for sunlight. Each player has to cover the largest possible area, as seen from the Kinect above, with their respectively colored blocks. These building blocks have a shape that supports a large variety of combinations and directions of the objects which results in a unique structure after each finished game.


The project is inspired by a research project by the PhD students Alexandru Dancu and Stig Nielsen who provided us with a technical platform that uses a combination of a projector, a Microsoft Kinect and pressure sensors to give live feedback indicating where the user should place building blocks for a stable construction. For our project, we kept the building part as the main focus of the game we designed, but we also made use of the color recognition and distance sensitivity of the Kinect.


The goal of the project is to design a concept for a tangible user interface for a two player game based on the already existing technology of the Kinect combined with a projector. In order to do so, we explore the possibilities and limitations of working with the Kinect combined with a projector. Another important aspect of the game is the playing pieces, why some focus is on designing and prototyping a suitable building block.
